July 28, 2020 the Hopniss is happy


Hi Gardeners

It’s a beautiful day here today with lower humidity and temperatures. Yesterday afternoon we had a nice, soaking rain of about 7/10 inch, which keeps me from having to water for a day or two. My zinnias are finally starting to grow well and bloom. The tropical plants are happy too.  The taro and elephant’s ear are getting huge leaves.

My new Joe Pye weed is in bloom and garden phlox are blooming. Some daylilies are in bloom and the lilies Casa Blanca and orientpet “Debby” are blooming.  Black eyed Susan’s and the shasta daisy are still blooming.  But it looks like I’m about to have that lull in bloom, just as I am expecting visitors to the garden in a week or two.  Isn’t that what always happens?  Of course, the annuals are still going strong, especially after the rain.

I’m starting to see lots of butterflies.  The hummingbirds must have their babies out of the nest and flying because there are little hummingbird battles all around the garden. They fight so fiercely, then they come to the feeders and get chased away by bees.

I was out with the dogs in the old pasture and kept hearing a weird noise. It sounded like a hawk scream, but odd. There were a lot of blue jays flying around and I thought one of them was mimicking a hawk. Then I finally saw him, a young hawk, I think a red-tailed hawk, sitting in a tree.  He was practicing his call, I guess. It was low and kind of muffled.

And after the rain the other day, which was late in the day, I saw a turkey vulture perch in a dead tree and spread his wings out, turned so that they were facing the sun. He sat there until the sun got too low to hit him, drying his wings. I love watching the birds and this time of year there are many to watch.

Oh, the weeding I need to do.  And now I will need to mow again. The grass is green and growing again. But when the days are like this, I still love summer. I am hoping the hot and humid stuff has mostly passed. After all we are a month pass the equinox and the sun is sinking lower each day.  We lose a few minutes of sun every day now.  How time does fly.

Seeds from China

You may have heard this already, but for those who haven’t people in several US states have received packages from China that contain seeds they did not order. These come in little plastic packages that fit in your mailbox. They are often labeled jewelry or electronics, but the inner package contains seeds.  The outer package may have Chinese lettering or say Chinese Post.

If you get one of these packages do not open the seeds.  Save the outer packaging.  Call 1-800-877-3835 or email SITC.Mail@aphis.usda.gov

Or go to this link and find your closest USDA office.

Contact the USDA office and they will tell you if they want the seeds and packaging or not and how to dispose of them.

Do not plant or handle these seeds. The motivation behind the seeds is unknown but packages examined contained mostly weed seeds.  It is thought the seeds may simply be a cheap way to do a scheme called “brushing”.  The packages are sent to people and then fake reviews are put online about a product to give it a good rating and the recipients name and other information is used in the rating. But there could be other motives.

Since the seeds were not inspected before entering the US, they could be a noxious weed, a dangerous plant or infected with plant diseases. And they are illegal to have, and certainly illegal to plant.  If you don’t want to bother with the USDA at least dispose of the seeds by burning the seeds and package.

Since we are talking about Chinese seeds let me repeat a warning about buying seeds on Ebay or Amazon.  There are all kinds of fake seed companies operating on these sites. They offer things like blue strawberry and rainbow rose seeds among other more common seeds. Inexperienced gardeners are often fooled by faked pictures of these plants and lured by low prices.

There are no blue strawberries or rainbow roses and they certainly wouldn’t be grown from seeds. Almost all of the seeds offered on these sites aren’t what they are represented to be. Someone emailed me pictures of strawberry seeds they received. The seeds were large, flat and light brown.  I have no idea what they were from, some weed behind the seller’s house I would imagine. You can see what strawberry seeds look like if you examine a ripe strawberry, they are the tiny black specks on the outside.

Buy seeds from reputable seed companies with a US based company. Seed companies from the UK and Europe usually have US outlets. They are going to cost more and generally charge a shipping fee. But you will actually get what you order. Ebay and Amazon just aren’t good places to buy seeds. By the time you realize you have been fooled it’s too late to get a refund in most cases.  The Chinese and other fake companies make a lot of money from those small, cheap packets of seeds.

Fall webworm (Tentworms)

A lot of people are getting excited and worried over fall webworms, often mistakenly called tent worms. While the “tents” look bad, the worms don’t harm the trees much. Often people damage the trees more with their control methods- like using a blow torch- than the worms damage the tree.  You can safely ignore the tents.


Fall webworms make a web like structure on the ends of branches that encloses leaves inside, which the worms feed on. They occur in mid to late summer. In spring the Eastern tent worm makes tents in the branch crotches and the worms leave the tent to feed on leaves.

Insects often have years when they seem to have a boom in population, and this seems to be a boom year for fall webworms. You know, why not? It’s 2020.

Side dressing sweet corn

If you are growing sweet corn and it’s starting to tassel, it’s time to apply a side dressing of a high nitrogen fertilizer.  This means sprinkling the fertilizer on the ground between your plants. If you are totally organic there are organic fertilizers, but you could use blood meal, I guess.

Corn is a heavy feeder and unlike some garden plants, needs a lot of nitrogen to produce a good crop.  Nitrogen is the one nutrient in the garden that disappears quickly.  When you fertilize at tasseling time, you’ll have a better chance of getting lots of big ears of corn.

Sweet Corn pollination information

Corn has two types of flowers on each plant, male and female. The male flowers are at the top of the plant and are called the tassel.  Female flowers are formed in a husk at the junction of leaves and the corn stem. You probably know them as “silk”.  Each strand of silk is a single female flower and produces a single kernel of corn. They’ll still be attached when you shuck the ear to eat it.

Wind shakes a cloud of pollen down on the silks to pollinate them.  Wind can blow pollen to nearby corn plants too. How the wind blows can affect how well your corn ears fill out with kernels.  That’s why it’s good to plant corn in blocks, rather than a single row. Pollen from a single row can just blow away and not get many silks pollinated. When you have ears of corn where only one side has kernels developed, it’s caused by poor pollination.

Corn is the one common garden plant where this year’s pollen can affect the taste or shape of this year’s harvest. That’s why it’s not a good idea to plant sweet corn close to field corn or popcorn. The kernels that develop from cross pollination won’t be as tasty or tender. And popcorn might not pop as well if sweet corn grew nearby. Separate corn types by at least 100 feet.  

You can sometimes grow two types of corn near each other if you carefully plan for when they will be pollinating so that one is far ahead of the other, but that is tricky to do.  Some types of sweet corn need to be isolated from other types of sweet corn for the best taste also.  You’ll see these listed in catalogs with a warning about what types of corn they should be isolated from.  These are usually the more expensive, super sweet varieties.

Hybrid corn is produced by planting rows of different varieties next to each other. Then the tassels are removed from one variety.  The ears from the de-tasseled corn will be hybrid, since they could only have been pollinated by the other variety. This used to be a job that farmers hired high schoolers to do every summer. The hybrid ears are generally used as seed corn for next year.

When corn is pollinating avoid spraying anything on it. Pollen isn’t carried by insects, but it needs to be fluffy and light to be successfully delivered to the silks. Oily insecticides for example, might keep pollen from landing on the silks.

Sweet corn takes a lot of room in the garden but if you have ever had sweet corn just after picking it, you will immediately want to grow corn every year.  There’s just nothing to compare with sweet corn picked at the right stage, brought into the home and cooked immediately and then eaten.

Hanging basket, containers and annual beds in mid- summer

If your hanging baskets, containers and annual beds are starting to look a bit straggly it might be time for two things, a fertilizer boost and a cut back.  If you act now your plants could bounce back and give you many weeks of color until frost comes.

Some people use the fertilize with every watering method of caring for baskets and containers. If you tend to water with the hose though, you may not be doing this. I use a granulated, slow release fertilizer in my baskets and containers when I plant in spring. Then I don’t worry about fertilizing them until right about now. If you used this method in the spring or you haven’t been fertilizing now is the time to do it.

If you want to use a granulated slow release fertilizer simply follow label directions for the amount to use, sprinkle it on top of the planting medium and water it in. If you want to use a liquid fertilizer mix it according to label directions and apply.  Most liquid fertilizers do not last long.  You may not want to use them with every watering but every week or every other week would be a good idea. Those of you already using diluted fertilizer every time you water don’t need additional fertilizer.

Annuals in the ground may not require fertilization, especially if you fertilized when you planted them. If the plants look dark green and full, they may not need fertilizer. However, if they look pale, yellowed or spindly a fertilization may be in order. Granular fertilizers work best for plants in the ground.

Should you trim plants back now? Many annual plants look better and flower better if cut back around this time in summer. Petunias that are straggly and long are a good example. Older varieties are more prone to doing this, newer varieties may stay compact and blooming all season.  Other plants that benefit from a pruning back are lobelia, straggly ivy geraniums, sweet potatoes that have gotten straggly, million bells, osteospermum, nemesia, bacopa, and any of those trailing plants added to containers.

When I do a pruning back, I take off about a third of the plant. They bounce back quickly from this.  If you are going on vacation and don’t mind the plants not blooming for a couple weeks to a month, you could prune back the plant to about half.  Prune off any dead stems, dead flowers and anything that looks really bad.

Other annuals do best with a good deadheading, cutting off dead flowers, but stems should not be cut back. This includes begonias, snapdragons, zinnias, cosmos, marigolds, salvia, most geraniums and any annual plant with a single stem.  Just remove the dead flowers.  Coleus is a kind of in between plant, some varieties that get long and lanky, with lots of bloom stalks might benefit from a prune back, more compact, bushy types can just have flower spikes removed.

I have pruned back plants that like cool weather, like pansies, diascia and calendula, back to an inch or so from the ground, after they have yellowed and start to look bad. In fall with good weather these may perk back up and bloom again.

The common ditch lily dies back in hot weather, if you remove the dead foliage it will probably green up again and look better in cool weather, although it will not bloom again. It is a perennial.

Oriental and Asiatic lilies, canna, dahlias and other bulbs can be trimmed back after the stalks have yellowed. They won’t bloom again this year and are perennial plants. Do leave the stalks to finish maturing and turn yellow if you want bigger, healthier bulbs the next year.

Hopniss or Groundnut

Apios americana, Hopniss, groundnut
How would you like a vine that’s native, edible, medicinal, and has pretty chocolate colored flowers? I have some growing rampantly in my yard, but I bet most gardeners have never heard of the plant. Hopniss or groundnut, Apios americana, is an unusual plant that more gardeners should try growing. I’m going to call it hopniss because groundnut is also a common name for the peanut.  It’s also called Indian Bean or Indian potato.



There is one other species of hopniss in the US called Price's Groundnut (Apios priceana). It is extremely endangered and found in one small area of Illinois. The flowers of this species are a light pink.  It has one larger tuber instead of many small ones.

Hopniss was a staple in the diet of many Northeastern Native American tribes and may even have been selected for certain traits and grown as a cultivated crop. It’s native from southern Canada to deep in the southern US from the east coast to the Rockies. It is becoming rarer and is listed as endangered in some states.  A few nurseries grow the plant and Louisiana State University has tried to develop hopniss into a commercial crop. Other universities have studied the plant for its medicinal qualities.  There is a small commercial crop grown in Japan.

The native habitat of hopniss is at the edges of moist woodlands and along rivers and streams in moist bottom lands. Hopniss is a vine or it sprawls over the ground if it doesn’t have something to climb. It will climb to 8 feet or more in a good site. The leaves are arranged alternately, pinnately compound, consisting of 5-7 oval leaflets. They remind me somewhat of wisteria leaves. 

Two butterflies use hopniss as a larval food plant, Epargyreus clarus (Silver-spotted Skipper) and Thorybes bathyllus (Southern Cloudywing). Deer feed on the foliage and small animals eat the tubers.

Hopniss flowers are intriguing. Bloom time is mid to late summer, with August being the bloom period in Michigan. The plants produce clusters of “curly” looking milk chocolate colored flowers, with a flared “hood’ consisting of two fused petals, two tiny petals near the bottom and a curious curved tube in the center that protects the pistil and stamens. 

The end of the tube appears to be buried at the top of the hood but if you so much as touch the curved tube it will coil away from the hood wall and the tip will slowly split, first the pistil and then the stamens will poke out.  You can watch it slowly happen.  I imagine that an insect landing on the hood area or the curved tube would also provoke the reaction.  After the flowers curved part has been activated the hood folds around the curved tube and is said to be “tripped”.  

It's not known for sure what pollinates hopniss.  Leaf cutter bees and flies do visit the plants. Leaf cutter bees have been seen to trip the “tube”. Honeybees occasionally visit the flowers, but since honeybees aren’t native, they are not the original pollinator.  However, the subject of pollination may not be important, as many plants do not produce seeds.

Hopniss comes in two strains, a diploid and a triploid. This refers to sets of genes that the plant has. It’s impossible to tell whether hopniss is a diploid or triploid by looking at it. In the north most hopniss is triploid and does not produce seeds.  Reproduction is from the little tubers the roots form.

Farther south and in a distinct region around the Black River in central Ontario,]some stands of hopniss are diploid and produce narrow, bean like, slightly curved pods. The pods have maroon seeds that darken to chocolate brown when dried. The pods split when mature and “shoot” their seeds.

Flowers and seeds of hopniss are edible.  The flowers are used medicinally in the treatment of diabetes. The beans were dried and ground into flour or boiled and eaten by Native Americans.

It’s the little tubers that form along the rhizomatous roots that earn hopniss the name groundnut and that are the primary food product. The tubers form along the roots like knots in a rope.  They are about the size of your thumb or smaller. They are dark brown on the outside and creamy yellow inside.  The texture is much like a potato.

These little tubers have about 3 times as much protein as potatoes and a different type of starch called oligosaccharides.  They also have lectins, a chemical found in raw beans. They are high in iron and calcium. The tubers should always be cooked before they are eaten.  Even so some people who eat the tubers will experience extreme gassiness and bloating and may have diarrhea.  It is said that a sensitivity in some people may build up after consuming it about ten times, causing an allergic reaction.

Native Americans collected hopniss tubers and dried them on mats for winter storage. They were powdered and used as a flour or boiled in soups. Some tubers were sliced and fried as we do potatoes. Hopniss was boiled in maple syrup to produce a type of preserves.  The taste of hopniss is said to be like a nutty potato and quite good.

Hopniss was one of the native foods that the first European settlers had to survive on the first winter after they arrived. It remained a popular winter survival food for many years.  Hopniss tubers were introduced to Europe and other places. Japan embraced them as an edible crop as they were similar to another Japanese crop.

Hopniss is said to be a signal to archeologists that an Amerindian site is nearby, so maybe my yard is located on one. The plants were here when I arrived and this house is over 100 years old.  Henry Thoreau is said to have eaten them when his potato crop failed.

Growing hopniss

Hopniss is a perennial plant and if you want to grow it you will probably start with tubers, not seeds. Just plant the tubers on their sides in about 3 inches of soil.  It likes light textured, moist soil in full sun to light shade. The plants fix nitrogen in the soil like soybeans, so they need little fertilization. It can take several years for the vines to grow until there is enough tubers for a harvest. Hopniss is hardy to at least zone 4.

If you grow hopniss for the flowers or for a screening vine, remember that they spread quite quickly in spots they like. They can take over a lot of fence or cover a lot of ground. The vines die back in winter and come back from the ground.  Most flowers in the north will not make seedpods.

Hopniss has few insect or disease problems. They may die back in very hot, dry weather.

Growing hopniss as a crop is tricky because of the perennial nature of the plant and the years needed for a crop. You dig up the vines in early fall after the first frost to collect the tubers. You can’t pull the vines out of the ground; they need to be dug.  Save some tubers to replant, right there after harvest.  Tubers are stored like potatoes, in a dark, cool but above freezing place.

Medicinal uses of hopniss

Hopness flowers are used to lower blood sugar. I believe a tea is made with them. Boiled tubers are used as a poultice on wounds. Eating the tubers is said to lower blood pressure, cholesterol and triglycerides and is being studied for those purposes.

There are chemicals in the tubers that have anticarcinogenic properties and one compound, Genistein-7-O-gentiobioside, is being studied as a treatment for breast cancer. It may also be helpful in colon and prostate cancer.

Hopniss is an interesting native vine with pretty flowers and many edible parts. You may want to include it in your garden.

July 21, 2020 garden going golden


Hi Gardeners

We got two rain events since I last wrote. One was almost an inch, a very good rain and the other, early Monday morning was about a half inch. We may get more tonight.  Plants love a good rain.  You can just see them perk up and shoot up. I hope all of you got rain if you needed it.


Getting good rains gives me more time to catch up on weeding and other garden chores since all my time isn’t devoted to watering. I still have to wait until the sun is going down because of the heat but I’m getting a little done.  I have been going around with the loppers and pruning snips and trying to get rid of the seedling walnuts and box elders popping up everywhere.

There was also a forest of giant ragweed plants growing in the back yard by the bird feeders, where the mower can’t get to them. Some of them were up to the eaves of the house, easily 8 feet and had stems 2 inches in diameter.  But they cut easily, and I got them before they bloomed. Yeah, the jungle is getting away from me.

Last week I talked about battling trumpet vine.  This week it’s been grape vines. We have an electric wire that runs from the house to the barn.  I noticed it was sagging then noticed the grape I had planted on the old dog kennel fence had scaled the 8-foot fence and started sprawling out on the wire above it.

I hated doing it because there were many clusters of little grapes hanging from that vine on the wire, but I had to cut it down. That many ripe clusters of grapes might have brought that old wire down. There are still a great many grapes on the vine if the Japanese beetles don’t ruin them all this year.

There’s also a wild grape I’m trying to cut out of the young oak tree and the old scotch pine next to it. Wild grape vines are everywhere this year it seems.  I’m cutting them out of flower beds and off poles and fences.

In the garden this week it’s turning golden. The large black-eyed Susan’s are beginning to bloom, the golden glow is blooming, I have lots of various colors of yellow and orange daylilies in bloom, the yellow martagon lilies are blooming, yellow canna’s are in bloom and the darn yellow quill mum is beginning to bloom already.

My oxycontin orchid, Epipactis helleborine, that exotic little invasive that some people would scream at me to pull immediately, is in bloom. I like it and have no intention of getting rid of it.  It popped up here 3 years ago in the shade of the oak tree. It’s up to 2 flower stalks now of tiny pinkish orchid like flowers. It has minute amounts of a chemical similar to oxycodone that intoxicates pollinators, but doesn’t harm them. If it does start spreading, I’ll pull or mow it. 
 
Epipactis helleborine,
Crocosmia is starting to bloom and the larger salvias. The oriental lily Casa Blanca is starting bloom. The pineapple lilies (Eucomis) are blooming.  Lots of hosta are blooming now, some hosta blooms are quite pretty. I have been picking cucumbers and I will pick my first tomato in a day or two.  Just waiting for that first BLT sandwich.

It’s supposed to storm on and off this week, and into the weekend. Across much of the US there’s a chance for severe weather this week.  Pay attention to your local weather and stay safe.

Weeds from birdseed

Do you feed the birds? If you do chances are good the seed has brought some weeds into your landscape. Even if you just feed black oil sunflower as I do some weed seeds will be present. In my case the oilers seem to be contaminated with giant ragweed.  It grows up around the feeders every year.

Birdseed is allowed to have a certain percentage of weed seeds in it. They are accidental contaminates for the most part, although certain seeds used in bird food are weedy in their own right.  Niger (thistle) for example and buckwheat, milo and wheat can also look weedy in the garden.

You can clean up spilled seed if you have no critters to do it for you. But even so, some seeds will manage to germinate. It’s probably best to move feeders away from ornamental gardens into the lawn, where sprouting weeds will be mown down.

Using just black oil sunflower and thistle will also be helpful. There is less waste with these seeds. Cracked corn can’t germinate, although it can mold and smell. The cheaper the birdseed the more likely it is to have weed seeds and seeds birds don’t like that well, like milo.  Buy the best birdseed you can afford, and you’ll have fewer weeds.

Potato Growing Tips

Lots of new gardeners are growing potatoes this year.  They are a crop that can really produce a lot of food in a relatively small space, and the crop can be stored without much preparation.  However, there are some differences in growing potatoes and other garden crops.  Here’s some potato observations/tips.

Potatoes are a crop that likes lots of moisture and cooler temperatures.  The hot, dry summer many places are having this summer is hard on them.  If it’s dry in your area, you’ll have a better crop if you water the plants deeply at least once a week.

Growing potatoes in containers is just for those who have no other place to grow them or for a novelty exhibition. You’ll get a much better crop if they are grown in the ground.  Containers should be quite large, 5 gallons at least if you grow potatoes in them.

If you are growing potatoes to get the maximum food production use large tuber, commercial type varieties like russets and red Norlands.  Heritage varieties have wonderful tastes but often aren’t as productive.

Potatoes have flowers similar to tomatoes, but they are purple or white. You’ll get potato tubers even if the flowers aren’t pollinated but if they do get pollinated, they may develop small fruits that look like green tomatoes. This is normal but the fruits are poisonous and should never be eaten.  The fruits have seeds, and the seeds could be planted, but it’s much easier and faster to use small potatoes or pieces of potato tuber to start new plants.

Potato flowers


A few weeks after you see the plants flower you may dig down and find some small potatoes. If you carefully remove some you can eat these as new potatoes and let the rest mature into larger tubers.  Try not to damage the roots too much as you do this.

After blooming the potatoes will start to yellow and die back. This is normal and when most of the vines have died and dried up you can harvest your crop. You can however, harvest potato tubers anytime after they start growing.  The tubers will also hold in the ground a long time before they need to be harvested without harm.  Animals may find them however, voles and mice like potatoes.  They must be harvested before a freeze.

Japanese beetle traps

I talked a little about Japanese Beetles last week.  Many people are buying Japanese beetle traps hoping to protect their plants but there’s something you should think about when you buy those beetle traps. Unless you have a large piece of property and can put the traps far away from plants you want to protect, these traps can actually make your problem worse.

Far away means 100 feet or more. Most subdivision lots won’t give you that room. The beetle traps lure Japanese beetles from a wide area.  Not all of them will go in the trap, many will pause to eat on your garden. As the traps fill up, they still lure beetles but it’s easier for the beetles to get out of the traps and continue feeding. 

And after feeding those beetles will be mating and laying eggs on your lawn areas. The eggs hatch into tiny grubs, that will overwinter in the soil and begin feeding on grass roots in the spring, emerging as beetles later in the summer.

Plants that attract Japanese beetles

Japanese beetles will eat over 300 species of plants, but they are attracted to some plants more than others. Here’s a list of plants that Japanese beetles really like;

Apple, crabapple, Malus spp
Asparagus, Asparagus officinalis
Japanese beetle on yellow dahlia
Cardinal flower, Labelia cardinalis
Clematis, Clematis spp.
Clethra, Summer-sweet, Clethra spp.
Dahlia, Dahlia spp.,

Morning-glory, Ipomoea purpurea

Red raspberry, Rubus idaeus
Rhubarb, Rheum rhabarbum
Rose, Rosa spp.
Sunflower, Helianthus annuus
Sweet corn, Zea mays
Virginia creeper, Parthenocissus quinquefolia
Zinnia, Zinnia spp.

Japanese beetles are also attracted to almost any yellow flowers and foliage. They prefer plants in sunny locations too.

Plants Japanese beetles don’t like very well.
Ageratum, Ageratum spp.
Begonia, Begonia spp.
Burning-bush, Euonymus spp.
California poppy, Eschscholzia californica

Poppy, Papaver spp.
Moss-rose Portulaca grandiflora
Nasturtium, Tropaeolum majus
Redbud, Cercis spp
Sedum, Sedum spp.
Violet, pansy Viola spp.

In addition, Japanese beetles rarely feed on evergreens like pines, spruce, junipers and arborvitae.

Hollyhocks

Hollyhocks are popular this year and I am glad to see an old favorite being used in gardens again. However, there are some things to keep in mind about hollyhocks.

Most hollyhocks are bi-annual. The first year they grow only vegetation, the second year they flower and then die. Many hollyhocks you buy in garden stores, especially if they are blooming, are not going to return next year.  There are some varieties that tend to be more perennial than others, coming back for several years but they are not long-lived perennials by any means.

The good news is that most hollyhocks will reseed if you let them and once you have hollyhocks blooming, you’ll probably have them for many years. If you collect hollyhock seeds plant them soon after collecting them, don’t wait for the next spring. New plants may start growing and you’ll have a good chance of them blooming next year. If you wait until spring to plant seeds the plants that come up probably won’t bloom that year.

A few new varieties of hollyhocks will bloom the first year from seed if you start them early inside. But be aware they probably won’t return the following year.

If you would like to know more about growing hollyhocks here’s an article I wrote about them.





How to can green beans

If you have an abundance of green beans right now you can either freeze or can them.  You can also buy them at the farmer’s market to store for winter.  To can them safely you’ll need to use a pressure canner.

Choose young tender beans for canning, the baby bumps in them should still be small. Go through them before using, discard any with bug holes, or that look discolored or moldy.

Purple beans usually turn green when cooked but using some yellow pod beans mixed with the green beans makes for pretty jars.

Wash the beans well then remove strings if they have them, use your fingernails to pull the “string” off the pod. Newer varieties of beans are stringless.  Cut off both tips of the beans.  You can leave beans whole or break or snap them in half.  If you like French style green beans use scissors to cut the bean pod down its length or use a special “frenching” tool. In pint jars the beans probably should be in smaller pieces.

Wash pint canning jars in hot soapy water.  Rinse well and leave them in a pot of hot water. You need a pint jar for every pound of beans you intend to can.

Now place the beans in a large pot of water and bring to a boil, boil for 5 minutes. Turn off heat.

Take your hot jars out of the hot water, drain, and place a ½ teaspoon of salt in the bottom of each jar.  You can leave out the salt or use less if you want.

Pack the hot beans loosely in the jars. There is some swelling during the canning process so don’t pack them tightly.  There should be 1 inch of headspace at the top of the jars.

Pour hot cooking water from the beans over the beans in the jar. The beans must be completely covered but leave the inch of headspace at the top.  You can boil extra water to use if you need to. 

Run a knife or bubble stick through the jars to remove bubbles. Wipe the jar rims.  Add lids to jars and tighten.  Place in pressure canner as your canner instructions direct.

For 0-2000 feet in altitude set dial gauges at 11 pounds, for 2001-4000 feet set at 12 pounds, 4001 to 6000, set at 13 pounds, above 6000 set at 14 pounds. For weight gauges use 10 pounds to 1,000 feet and 15 pounds above that.  Follow instructions for adjusting pressure on other pressure canners.

Process pint jars in a pressure canner for 20 minutes. Turn off heat.

Let pressure release, following your canner directions. Remove jars, wipe, and let cool. Check seals, label and store.

I used pint jars here because for a small family that’s the average size needed for a meal. Quart jars need 25 minutes processing time.  If you use other size jars you’ll need to look up canning times and pressures for them.

July 14, 2020 trumpet vine troubles


Hello Gardeners

Trumpet vine flowers
Trumpet vine is a pain in the butt. I know it’s a native and hummingbirds like it but think very, very carefully before you get it started in your garden. I didn’t start the trumpet vine growing here, it was here when we moved in. Last night I was out in the far reaches of the yard trying to untangle a big hydrangea bush from the trumpet vine bully.


It’s been too hot to do a lot of work in the sun, so I kind of ignored that plant way out there in the yard.  And then I noticed orange flowers mixed in with the white hydrangea flowers and knew I had to act. Its pretty in a way but I knew if I left the trumpet vine the hydrangea would suffer. 

There was so much trumpet vine in that hydrangea.  It had to move underground, across a mowed space about 30 feet wide to come up in the hydrangea. I began breaking and cutting it out – it breaks easily- and I had a huge pile of branches on the ground.  Then suddenly, as I got close to the center of the plant I ran into a problem. Birds nest. Yep a small bird of some type had a nest in there.  (Not a hummingbird though). 

I left the nest and the remaining trumpet vine for now. The nest looked unoccupied but in case it was soon to be a bird home I decided to wait a bit. Goldfinches are still nesting.  I’ll check in a week or two and see if its still unoccupied.

Want to know more about trumpet vines? Check out this page.

I don’t know how many of you got rain last week. We got less than a half inch although places around us got much more.  We have entered what meteorologists call “very dry” conditions but it sure looks like drought to me.  After a few days of cooler weather, it’s hot and humid again today and it’s supposed to stay that way for a long time.

Most of us in the US are going to sweltering until the end of July, at least, because of this big dome of high pressure over us.  It’s supposed to be a bit stormier this heat wave than the last. The plants would handle the heat much better if we got more rain.

Many of my hosta that are in sunnier locations are showing leaf scorch.  They are getting watered regularly, but the heat and sun are too much. I am noticing some trees and shrubs are starting to droop and it’s hard to get water to them. 

I mowed the lawn and pasture this weekend just because things like trumpet vine, bristly locust, black walnut, bamboo, and staghorn sumac don’t mind sending out runners to colonize the areas around them even in a drought.,

Even though I water, the zinnias, cosmos and other annuals I planted from seed are very short and are starting to flower with very small flowers. I have a mum beginning to flower- in July- it’s probably heat stress. All the orienpet lilies are beginning bloom, the martagon lilies and Asiatic lilies are blooming.  Daylilies are blooming. My new climbing rose hasn’t grown very much but it is flowering, quite a pretty red and yellow flower.

The lavender likes this weather. It’s blooming like crazy. The cannas and dahlias are finally starting to bloom. Woodland nicotiana, cleome, Joe Pye weed, English daisies and snapdragons are in bloom.

In the vegetable garden I harvested a small cucumber and a red pepper this week.  I’ll have tomatoes soon.

Weeds that spread disease to your plants

When it’s hot and plants are mature enough to compete well with weeds, gardeners sometimes give up on weeding.  Besides the fact that weeds shade garden plants and compete for water and nutrients, there is another reason to keep weeds out of the garden. Some weeds also bring disease and harmful insects into the garden.

Common lambsquarters, pigweed and nightshade all get some of the fungal diseases that tomatoes and potatoes get.  These are extremely common weeds in gardens.  They can serve as a source of infection for early and late blight and also septoria leaf spot.  Nightshade is a perennial and some fungal diseases may over winter in its living tissue.  Petunias, while not a weed, can also carry some tomato-potato diseases.  Don’t plant them near those crops.

Lambsquarters


Dandelions and wild carrots or Queen Anne’s Lace, growing near garden carrots may be a source of “aster yellows” a disease that infects garden carrots. They are spread to carrots by an insect called a leafhopper that feeds on both types of plants.

Many viral diseases are spread by aphids, leafhoppers and beetles feeding on infected weeds and then moving to related garden plants. Tobacco mosaic virus of tomatoes and peppers, cucumber mosaic virus and powdery mildew are some diseases that can be spread by insects from weeds to garden plants. Pests like the tomato hornworm may begin feeding on nightshade and then move to tomatoes.

Here are some other weeds that are important to remove from your garden to help control disease and insects.  Prickly lettuce, sowthistles, Canadian goldenrod, ragweed, shepards purse, purslane, yellow rocket, dayflower, deadnettle, teasel, heal all, chickweed and bur cucumber.

Prickly lettuce


If you grow raspberries or blackberries in the garden all wild brambles should be removed for 100 feet around your plot.  They serve as a reservoir for rust and other diseases.

Neem oil- and how to use it in the garden

Neem oil is the newest wonder product of the plant world, although it’s been around gardens a long time. While Neem is a chemical product derived from a plant, it is a registered pesticide and should always be treated as such.  While it is considered organic and is less harmful than some other chemicals, there are still risks associated with the use of Neem, and it can have toxic effects, including death, to humans and animals if not handled in the right manner. Neem can also kill or damage plants if not applied properly.

Neem oil is derived primarily from the seeds of a tree native to India and Burma, (Azadirachta indica). Other parts of the plant are also used for various commercial uses. There are a number of different formulations and strengths of neem oil.  Azadirachtin is the chemical in neem oil responsible for its pesticidal effects.  However even neem oil purified to have little of that chemical retains some pesticidal advantage.

Neem oil works in two ways to kill insects, by smothering those it directly contacts and by altering hormonal activity in those that ingest it. When the oil gets on an insect it is non- selective- that is it kills both good and harmful insects. However, when the spray has dried on plant leaves only insects that eat the plant will be affected. It can take some time for insects ingesting neem to die.

Not all insects are equally affected by neem oil. It doesn’t seem to do much to Japanese beetles for example. Soft bodied insects like aphids are more easily killed by neem oil.

Neem is also used for some fungal diseases of plants. It does not cure plants of fungal disease, rather it limits the ability of the fungus to reproduce and spread. It can be used as a preventative for fungal disease because fungal spores landing on treated foliage do not reproduce well.

Neem oil won’t help plant problems caused by environmental factors, such as blossom end rot in tomatoes.  It is not a fertilizer and won’t correct nutritional deficiencies. Neem oil won’t kill mosquitoes, ticks or fleas unless it gets directly on them and it should never be applied to humans or pets to control these pests. Neem oil is moderately toxic to fish and other aquatic life and should never be put in natural water or ornamental ponds.

No pesticide, including neem oil should be used unless necessary. Try other non-chemical means of controlling pests first, such as hand picking or trapping insects.  Neem oil is not harmless, as many gardeners seem to think, and should be used carefully.  Plants often experience problems from the application of neem oil, especially if it is done more often or in stronger concentrations than recommended on the label.

Damage to plants from neem oil includes yellowed, dying foliage, areas that look scorched or bleached, death of new growth, wilting and distorted foliage and flowers.  Poor growth and stunting may occur with frequent use.

If you want to try neem oil in your garden always buy a product intended for garden use. (There are neem oil products for human cosmetic and medicinal uses.)  Then read and follow the label directions carefully. Usually if mixing is required only water is used.  DO NOT MIX NEEM OIL WITH OTHER PRODUCTS.  Do not add soap, vinegar, baking soda, or other things.  These things can interact with neem oil and make it more harmful to both you and your plants. There are many “homemade recipes” out there that raise the harmful effects of neem oil considerably.

Neem oil should be applied to plants in the early morning or evening when pollinators are not active.  It will kill pollinators and other beneficial insects if it contacts them. Don’t apply neem oil to flowers pollinated by insects. It should not be applied when the sun is high as neem oil often causes a photoreaction “burn” if applied in the sun. Don’t apply it when temperatures are above 95 degrees F or below freezing.
  
Do not apply neem to newly transplanted plants, or wilted plants. Doing so may kill or damage them. Some species of plants do not tolerate neem oil well and it shouldn’t be used on them.  Those plants include impatiens, carnations, hibiscus, and fuchsia as well as some other less common plants.

Always try a little neem oil pesticide on a small part of a new plant first, especially if it is a valuable one, and observe for 24 hours.  Even if you have used neem oil on a plant before different environmental conditions or different neem products can cause plant damage. Tender new growth on any plant is more likely to be burnt by neem oil.

Human and animal problems

When used as directed on the label neem oil has a low toxicity to humans, wildlife and pets. It can be used on food crops safely, but produce must be washed before it’s eaten. However, if it is mixed with other products the mixtures can be harmful. Birds and animals do not seem to have problems eating plant parts treated with neem. Fish are harmed by neem and it should be kept out of natural water bodies.

Some people have reported that cats are more sensitive to neem oil toxicity than other pets. They should not be sprayed with neem and probably shouldn’t ingest plants sprayed with it. However not much has been reported in science based articles on the subject.

Neem oil pesticide products must never be directly consumed by pets or children. Keep products out of their reach. Death can result from this and poison control should be called immediately. It can cause severe vomiting, convulsions, metabolic acidosis, kidney failure, encephalopathy and severe brain ischemia.  Yes, there are neem products like toothpaste and herbal preparations that people use in moderation, but neem pesticides are not safe to consume. 

Avoid getting the neem products on your skin-the pesticide can be absorbed through the skin. Many people have allergic reactions like rashes when neem oil gets on skin. Do not use neem oil for gardens on people or pets to control things like lice or fleas. There is a neem preparation for lice sold, but it can be a harsh treatment.

Neem oil is very irritating to the eyes.  It can cause problems if spray is inhaled also.  In herbal medicine neem is used as a contraceptive and to cause abortions (among many other things). It is known to cause reproductive problems in animals exposed to it. If you are pregnant or trying to become pregnant, I would be very careful using neem products.

Neem oil can be helpful in the garden with low toxicity.  However, it is still a pesticide and should be used exactly as directed on the product label.  While it works well to control some insects and aids in controlling some plant diseases it does not solve every garden pest problem.

New Garden? How to decide what to plant

Do you have a new garden spot you want to develop or a garden area you want to renew?  Many people are hesitant to trust their own judgement when choosing what to plant or they don’t have any idea of what species of plants they can choose from.

Here’s how many new gardeners plan a garden. They show a picture to social media and ask what to put there. They are bombarded with suggestions reflecting with what each person likes and dislikes, often without regard to conditions at your garden or size of the plants you need. And it’s often apparent the people offering the suggestions really don’t know much about the plants they are suggesting.

Or the new gardener asks for plant donations and accepts everything anyone offers. They cruise stores for deals and marked down plants.  Free plants and deals are fine- if they are plants that will suit your growing conditions and stay within your garden boundaries. New gardeners should be very careful adding marked down, half dead plants to their new garden.  It’s a good way to get some insect pest or disease started.


The right way to plan your garden

Do your research first. Know what plants will grow in your planting zone and growing conditions. People always want to skip any research and just ask someone for help. But there is so much to learn that conversations with friends and people online just can’t substitute for a little research. I am going to give some tips here, but you still need to do some research and make some decisions.

It helps to decide on a look or theme you want for your garden, formal, low maintenance, cottage garden, all native, wetland, and so on. Look at other people’s gardens, public gardens, gardens in books and online.  Be aware that formal gardens, those with sheared hedges and topiary plants, generally need a lot more labor than less formal gardens.

Decide what you like. Don’t let people intimidate you into only native plants or a formal garden if that’s not your idea of a garden. Your garden should be what you like, not what others want.

To plan properly you must know your garden zone.  This is very important as you select perennial plants.  It determines what plants are likely to survive winter in your zone and thrive there. You can choose plants with a zone rating lower than yours or the same as yours but choosing plants with a higher zone rating will probably be a waste of time and money because they won’t survive in your area.

You can find that information here.


What kind of light conditions does your garden spot get? Remember that light conditions will change somewhat during the year as the suns position changes. Determine your average light conditions by observing the spot about this time of the year- late June-early July.  Full sun is considered to be about 8 hours of sun a day. Partial shade is 4-5 hours of sun a day. Light shade is filtered light through a small tree, or lattice. If the north side of a house doesn’t get any additional shade from trees or other buildings, it’s probably light shade. Full shade is no direct sun.

Check your soil type. Is it sandy, nice loam, or clay?  All kinds of soil can support a nice garden and there are plants that will grow in just about any soil type. What is the drainage in the spot? If water puddles there after a good rain and stays for more than an hour you probably have poor drainage or a wet spot. You’ll have to fix the problem or choose plants that tolerate wet roots.

For new gardeners it’s always a good idea to get a soil test done.  That will tell you the soil pH, (whether your soil is acidic or alkaline), and some basic information about soil fertility. Call your local county Extension office to find out how to submit a soil sample.

Next consider the time you have for gardening. Do you need low maintenance plants?  Then check to see if there are any laws or ordinances for your site that might affect what plants you can have.  In most places there won’t be, but some neighborhood associations and cities or villages do restrict what you can grow. They may require vegetable gardens be located in the rear of the house for example.

After you have done all this research, make a list of the plants you like that are suitable for your garden conditions and keep it handy.

First year


How a professional garden designer would work

A professional garden designer, or garden architect, would go about the project this way. They would come and thoroughly measure every aspect of the new garden site, including the length, depth, width, distance to trees, tree canopy space, location of buildings, decks, patios, drives and walks, location of wells, air conditioning units, meters, underground utilities and other obstacles. They would measure the distance from the ground to the bottom of windows that might be in the proposed garden space, and the distance between windows and doors in the space.   

A detailed, to scale drawing would then be made on graph paper showing all of these things. After a design is created using simple forms like circles, tall ovals, boxes and so on to indicate plant shapes, the designer would develop a list of plants that fit the site conditions and then would indicate the plant species on the design. The mature sizes of the plants would be used to decide what would fit where and their natural forms would be used to complete the design- a rounded form for a circle on the graph for example

People planning a new garden can do this themselves and it can be invaluable in planning. Bring out that list of plants you like that fit your conditions.  Make sure the mature height and width of those plants is included. Now get some graph paper. Graph paper has little squares evenly covering it and its available in most places paper is sold.
Assign a measurement such as 1 foot, to each square on the graph paper. Put in all the measurements you have taken- where the trees, windows, paths and other things are located on your “plan”.  Make sure you draw them in scale, if a path is six feet wide and each graph square equals 1 foot in the real garden, then you would block out 6 squares on your plan for the width of the path and as many squares long as the actual path runs.

You can then decide how many plants you can put in the space, allowing for paths and other things.  Use your prepared list of plants. Some people like to color in the square to coordinate with what the actual bloom color or foliage color of the plants might be.

You may want a separate drawing for every area you intend to plant in.  Make a master copy with the measurements and then you can make copies that you can mark up and move things around on.  Even a basic rudimentary drawing is better than no plan.

Quick general suggestions

Before you start any digging, you need to know if there are any underground pipes or wires you might damage. You also need to see where overhead wires are and to know where your property lines are located.

Put taller species in back or the center of a bed that can be seen from all sides. A variation in plant height is more natural looking, with the shorter plants in front.

Don’t just choose plants for their flowers, how they will look when not flowering should be considered. Some things will die back after flowering and disappear. You’ll want something present in the garden all season and you may want winter interest too.

If you like flowers- some people prefer mainly foliage- try to choose plants that bloom at various times, spring, summer, and fall. Most perennials have one bloom period, they don’t bloom all season. You may want some of the few that do bloom for long periods like the landscape roses, to keep color in the garden all season. It’s also good to add some annual flowers each year to fill in when the perennials aren’t in bloom.  Annuals tend to bloom all season.

One big hint. Don’t choose plants at a nursery because the flower colors look good together unless you carefully look up the normal bloom time for the plants and the growing conditions they require.  Plants in nurseries often don’t bloom at the same time they would in your garden. Those plants may never bloom again at the same time and worse they may require different growing conditions, so they can’t be grown together.

Color schemes should suit you. Formal gardens tend to have one or two main colors with an accent color here and there. Informal gardens tend to blend many complementary colors.  Some people find a simple color scheme soothing and pleasing. While other people are more attracted to the riot of “anything goes” color schemes. Do what you like.

Foliage color should also be considered. Various shades of green and perhaps some variegated foliage are more pleasing to the eye than one shade of green.  Don’t overdo “accent” colors like golden or purple foliage plants. One or two is nice, a whole garden of golden or purple foliaged plants is generally not very appealing.

Choose a variety of shapes and textures of plants. Formal gardens will have less variety and informal gardens more. That does not mean that every plant should be different. Generally, plants look better in clusters of 3 or more but that’s not a hard and fast rule. Sometimes one larger plant can be a focal point, a weeping tree or Japanese Maple for instance.  And small areas may only be suitable for one plant of each kind instead of clusters.

If you are offered plants or see bargains refer to your plant list.  Don’t take just anything because it’s free or cheap.

You may have to plan your garden in stages, in fact that’s an excellent way to start. You learn over time to save up for a large, quality plant instead of settling for a cheap seedling from a little known company that you are going to have to replace 3 times or that will take 10 years to grow to blooming size.  Buy a few good plants instead of a lot of bargain bin half dead plants.  Next year add a few more quality plants. 

When you do have a budget to consider, buy the plants that will be focal points or the largest plants first. They can be growing in your garden, getting large and beautiful as you fill in around them.

New gardeners tend to jam too many plants of too many species into a garden. You probably cannot have every plant you’ve ever admired in the same garden bed, unless it’s very large.  And it’s tempting to plant too closely when plants are small. Plan for the mature size of the plants. The old saying first year they sleep, second they creep, third they leap is pretty accurate. Until they “leap” you can fill in with annual plants.

Gardening is a learning experience and you need to take the time to learn a little about it. Planning a garden is a lot of fun, or it should be. You won’t get your garden perfect the first time. It will need to be tinkered with and improved. Every gardener I know is planning changes for the next year. But starting with a plan and some knowledge will get you better results than just jamming a bunch of plants you know little about into an empty space.
