December 11, 2018


Hi Gardeners

Another cold and gloomy day here in Michigan but I won’t complain too much.  It could be much worse- like North Carolina.  Soon the longest night will pass and we’ll be climbing the hill again.

I am already planning what new things I’ll buy for the garden next year.  I am exploring catalogs and websites to add to the list I keep on the right side of the blog- and I see so many interesting things I’d like to grow.  I’ll be adding new listings to the page through January- take a look when you have time.

The birds have been busy at the feeders. I hope you are feeding the birds because it’s so interesting to watch them in the winter.  I put out only two items in the winter, black oil sunflower seeds and suet.  Ninety percent of the birds here in winter are attracted to those two items and nothing else is needed. I have tried mixed bird seed, but the birds waste a lot of it. Cracked corn is liked by some birds but it attracts deer so it doesn’t go out here.

I spent some time moving my plants around indoors this weekend because I wanted to bring the amaryllis’s off the porch into warmer conditions. That took some juggling, but I managed. My holiday cacti are all blooming nicely now.  Hibiscus are blooming nicely too.

I was noticing on the porch how nice the large canna still looked. They aren’t blooming but the foliage is still pretty, and they are actually adding new leaves.  They could be a candidate for those of you who like large, big leaved houseplants. Just bring them in before frost.  I keep mine potted to make that easier. 

There are many colors of canna foliage.  I have a maroon and a green leaved variety.  I let the tropicanna variety, with striped foliage, get hit with frost and it hasn’t come out of dormancy yet.  I think that canna could even bloom inside if they had enough light. I just don’t have room for canna’s in the main part of the house.

I will be busy baking cookies and making meat pies this week.  I hope all of you are making and eating your favorite holiday foods and seeing your favorite people.  Just don’t let the rush of preparing for the holiday spoil your joy.
  
Holiday plants you may want to avoid

Plants have been brought into the home to decorate it around the winter solstice for hundreds of years.  They have become part of the tradition and lore of the holidays and the practice persists even today.  But not all holiday plants are safe for children and pets and knowing which ones are poisonous is important for a happy holiday.

The poinsettia has long been listed as a poisonous plant, but as toxic plants go, it’s probably not that harmful.  Yes, if someone ate a lot of poinsettia there could be serious consequences, but that scenario is unlikely.  The sticky white sap of the poinsettia is unpleasant tasting enough that even the naughtiest dog probably wouldn’t eat enough to get more than a stomach ache.  It would take eating several large plants to be lethal to a pet or child, if that.

Mistletoe on the other hand is extremely poisonous and just a few of the berries dropped on the floor and eaten by a pet or child could cause death. All parts of the plant are toxic, dried or fresh. Mistletoe is a plant that does not belong in homes where children and pets are present.

Holly is often used in decorating for the holidays but all parts of the plant are poisonous.  The leathery leaves would be unlikely to be eaten but the bright red berries that some holly has would be attractive to children and pets. 

Another very poisonous plant that is sold around the holidays as a potted plant is the Jerusalem Cherry (Solanum pseudocapsicum).  The plant is a compact bush-like house plant with glossy green leaves and bright orange-red berries.  All parts of this plant are poisonous.

In fact, around the holidays many plants with red or orange berries are sold.  Some of these are new to the trade and little is known about their toxicity - whether they are poisonous or harmless.  It’s a good idea to place any of these attractive plants out of the reach of children and pets.  Always keep a plant label with a plant so if any part is ingested you can tell poison control what it is.

Amaryllis bulbs are often sold around the holidays either in bloom or as kits that you add water to and watch it grow.   They are often sold as a bulb in fancy pots.   They have long strap-like leaves which appear after the bloom stalk.  The amaryllis bloom is trumpet shaped; there may be one or several blooms on each tall stalk.  It comes in red, white, pink and other pastel shades.  All parts of the plant are poisonous.

Another bulb often given as a gift kit is the narcissus or daffodil bulb.    The common one sold is called paper white narcissus.  They are often set in gravel and water to grow roots and bloom.  They have flat, grass like leaves, and the typical daffodil flower of a “cup” surrounded by a ring of petals.  They are white or yellow and have a strong fragrance.  All parts of the plant are quite poisonous as is the water surrounding the bulb, or if the blooms are cut and put in a vase of water, that water is also toxic.  Narcissus and daffodils should never be put where children or pets might taste them or drink the water they are in.

Yews are not used as often as some evergreens for holiday decorating but they are sometimes used in floral arrangements and unsuspecting homeowners may bring branches inside for decorating.  They have soft, flat dark green needles and are often sheared into hedges around a home. The yew is an extremely toxic plant with only a bite of the plant causing death to a pet.  It sometimes has fleshy red berries with a hard seed inside that attract children and pets.  The soft part of the berry is harmless, but a few swallowed seeds can be deadly.  A mouthful of the plant can kill a grown cow.  It is not a plant that should be brought into the home.

Sweet Annie or other kinds of wormwood (artemisia) are often used in wreaths and other dried arrangements.  While unlikely to be eaten in quantity, these plants are also poisonous, and munching should be discouraged.  Since wreaths, dried arrangements and fresh floral arrangements can have all sorts of exotic plants tucked in them and might be sprayed with chemicals, it’s a good idea to keep them out of the reach of children and pets.

Growing Hazelnuts or Filberts
Immature hazelnuts

A new study by Oregon State University found that when older adults were given about a third cup of hazelnuts per day for 16 weeks it improved their blood levels of magnesium and vitamin E.  These two nutrients are often lacking in modern diets.  Other studies have found that people with low levels of these nutrients were at greater risk of developing Alzheimer’s disease. Did you know that most gardeners can grow these healthy nuts?
Some of you may know hazelnuts as filberts. Hazelnuts and filberts are essentially the same thing. The name depends on what country you are in and what species of Corylus you are growing.  There are native hazelnuts in both Europe (Corylus avellane, Corylus maxima) and North America (Corylus americana, Corylus cornuta).  There are also other species and hybrids of species.
Hazelnuts have alternate, heart shaped or oval leaves with toothed edges, (double serrate) that are paler green underneath and sometimes lightly hairy.  
These nuts grow as small trees to about 15 feet or as shrubs depending on the conditions and pruning. Hazelnuts spread by suckering and soon form thickets of trees or shrubs. They are deciduous and fall color is variable, ranging from a dull yellow to pretty rose or purplish reds.
Male flowers are long yellowish drooping “catkins” that appear before the leaves.  Female flowers are small globes with red "petals” (stigmas) sticking out.  They also appear before the plant leaves. They are in clusters and a rough, jagged looking set of leaf bracts will surround them as they mature into nuts.
Each hazelnut plant has both separate male and female types of flowers but flowers on the same plant cannot mate in European hazelnuts and while you may get some nuts from a single American hazelnut, production is greatly improved with two or more plants. They are wind pollinated. For best production plant at least two hazelnuts.
The seed (nut) has a tough leaf bract, a thin hard shell, and a papery husk before you get to the part we call the nut meat. (Leave the shell on if you are planting a nut.)  It takes 7-8 months to mature on the tree and then the nuts fall.  Harvest is done by picking up the nuts after they fall.
Hazelnuts are cold hardy to at least zone 4 but nut production is often diminished from late frosts in zone 4-5. They will grow in most types of well drained soil and prefer full sun. In the south they tolerate partial shade but don’t produce as well in those conditions.
Gardeners may want to buy small trees to start a hazel nut grove. If you plant 3 feet tall trees, you’ll probably get a harvest in about 3 years.  It takes about 8 years to a harvest from planting a seed.  Buy domesticated cultivars if you want nuts for personal use as the domestic cultivars have larger nuts and a more abundant harvest. If you want them for wildlife, you can plant wild types.
Since hazelnuts sucker and produce a dense thicket if left alone you should prune out suckers too close to each other, leaving at least 6 feet between plants. Or if you want neat, tree shaped plants remove all suckers. You can prune hazelnuts so they form a shrub, to make them easier to harvest, by pruning down the leader or main stem by about a third.  Prune when dormant to shape the plant but you can take out suckers at any time.
Hazelnuts mature over an extended time period and will be ripe up to a month before they fall from the tree. Ripening may begin in September.  It’s easier to wait until they fall to harvest them, because you will know they are ripe then. You can give the trees a shake to speed things along.  Mow the area under the trees short when they start falling so you can see them.  Pick them up daily or animals will get them. The nuts may have fallen without the papery bracts or you can remove the bracts from nuts.
After you pick them up spread them out on newspaper in a warm, dry place for about two weeks.   A ripe nut has a firm, cream colored meat.  Nuts in the shell will last several months.  If you remove the nut meats store them in closed containers in a cool place.  Freeze them if you will be keeping them more than a month.
Hazelnuts are prone to blight diseases and some areas have problems with one strain of blight while others have problems with another. Look for blight resistant varieties grown locally. Dorris, Jefferson and Felix are some blight resistant varieties. Many animals and birds like the huts and you will have to compete with critters to get them.
Two types of worms, the filbertworm and the nut weevil, can infect hazelnuts.  This will leave tunnels in nut meats, or you may see small worms.  These will need to be controlled by insecticides.  Talk to your local Extension office to see what to use and when to apply it.


The countries that produce the most hazelnuts are Turkey, Italy and the United States in that order.  Hazel nuts can be eaten raw or roasted, made into a paste or “butter” and an oil can be expressed from them. They are often combined with chocolate in desserts called truffles, used in cakes, made into the spread called Nutella and a liqueur called Frangelico. 
There is an effort by the Arbor Day Foundation to locate wild North American hazelnuts so that genetic diversity can be preserved. If you know where some are growing you can contact them at;  https://www.arborday.org/programs/hazelnuts/consortium/locate.cfm

Can your spices make you sick?

Do you sprinkle your food with black pepper when it’s on your plate?  You may want to reconsider that practice and how you use other herbs and spices.  We often don’t stop to think about spices and herbs being responsible for food poisoning or lead poisoning, but we should be paying more attention. Spices and herbs have caused several confirmed outbreaks of food poisoning in the US and numerous hospitalizations and even deaths.
 
A new study done in New York found that many herbs and spices are contaminated with all sorts of things, such as heavy metals like lead, pesticides, molds, and bacteria like salmonella and E. coli.  Insect parts, rodent feces, animal and human hair, plastics and other synthetic material are also common contaminants.

Studies have found that the spices most likely to be contaminated with salmonella are black pepper, thyme, oregano and turmeric. The New York study found the highest levels of lead in a spice called kviteli kvavili, or "yellow flower." Other spices with lead contamination included turmeric, hot pepper, chili powder, and paprika.  But all spices can be contaminated.  Cinnamon and ginger rarely have bacterial contamination because they have anti-bacterial properties, but they can be contaminated by other things like heavy metals and filth.

Most spices are grown in other countries.  We have little control over the conditions they are grown in, stored in, and processed in.  Contamination can happen in the fields they are grown in, from harvesting or in the packaging, storing and shipping process.  Spices and herbs that get damp for example, may grow molds, some of which are carcinogenic.  Expensive spices are often cut with other cheaper plant products, and they may not have been harvested cleanly.

Spices are often a small farm crop and in many countries these crops are fertilized with manure, and animals roam the fields and may even be used in harvesting.  Irrigation water may be contaminated with heavy metals, pesticides are used that are banned in the US.  The nature of spices and herbs means they are often stored for years, in various types of facilities.  And harvests from different farms and even different countries are mingled, making contamination difficult to trace. The FDA tries to test spices for contaminants, but our system currently doesn’t test every package in every shipment. 

Where should you buy spices?

While many people feel they are getting a bargain when they buy bulk spices and others think buying spice mixes sold at farmers markets or flea markets are tastier and fresher, those are the two places with higher levels of contaminants in several studies.  Bulk spice containers where consumers scoop out their own often test positive for bacteria common to human feces.  You may have noticed people scooping up a bit of bulk spice with their hands to smell or taste.  Children may be allowed to put their hands in bins. Mice and roaches may roam the store after hours. 

While some spices sold at farmers markets may be locally grown and dried many are simply repackaged mixes of bulk spices the seller purchased elsewhere. There are many spices that aren’t grown in the US.  Every time spices and herbs are handled increases the risk for contamination. Improper storage containers, ones that aren’t sealed, are also a problem.  Some sellers may have meticulous handling practices as they package spices, but no control over how the bulk spices they purchased were handled.

Researchers feel the safest spices and herbs to buy are those that are individually packaged in sealed containers soon after harvest by reputable companies.  Those little cans and bottles may cost more than bulk spices, but they are safer.  A sealed can of black pepper, for example, can be stored safely for years.  Large, well known companies are also likely to test for heavy metal and pesticide contamination.  Avoid bargain spices and herbs, spices sold bulk, and farmer and flea market offerings. 

Also, bacterial contamination of spices is harmless if they are heated to 160 degrees F for 5 minutes or more.  That means season the food before you cook it and avoid adding spices and herbs after cooking.  Also, be careful using spices on foods that aren’t cooked. Of course, heat won’t remove heavy metals or pesticide contamination.

If you grow your own spices and herbs, make sure they are dried in a clean place and that they are kept away from animals.  Handle them with clean hands.  They should be stored in tightly sealed containers.

Go through your spices and herbs periodically and throw out the older ones.  Store the herbs and spices in their original containers tightly closed or put them in containers which can be tightly sealed. When you measure spices and herbs pour them into the spoon instead of dipping the spoon into the container.  When adding spices to cooking food put the spice in a spoon then add it to the food.  Sprinkling spices from the container over hot food often results in steam getting in the container, which can cause caking and also mold.

Spices and herbs make food taste better and even have health benefits, so I am not trying to discourage you from using them.  Just use caution about what herbs and spices you buy and how you store them.

Christmas gifts for gardeners

Need some ideas for gifts? If there’s a gardener on your list here’s dome ideas.
The number one thing you can get gardeners for Christmas is a gift certificate to their favorite garden store or catalog.  If you need a list of catalogs look to the right of this blog where I have assembled a page with links to hundreds of catalogs.  Or look around the gardener’s house- what garden catalogs are lying around?  And it’s not just plants, a gift certificate for a load of compost, manure or woodchips is also appreciated by many gardeners.

Buying actual plants can be a tricky situation unless you too are a gardener and know the gardener you are buying well.  If they have expressed the hope or desire for a certain plant and you can find it then that’s probably a good choice.  But if you don’t know what plants a gardener likes or has the right conditions for, it’s probably better to go the gift certificate route.  And remember live plants have to be properly cared for while you are waiting to give them to a gardener.

An amaryllis bulb is often a good plant choice for a gift.  Many are sold around Christmas with elaborate planters.  They vary in price from around $10 for a common colored, smaller bulb in a plastic pot to more than a $100 for large or multiple bulbs in gorgeous pots.  There are rare and unusual colors and flower shapes to choose from for the gardener who already has the common red amaryllis.  Amaryllis bulbs are good choices for introducing kids to gardening.  The bulbs are easy to get to bloom (that first time anyway) and make an impressive flower display indoors in winter.

To learn how to keep your amaryllis bulb and get it to bloom again see this article; https://gardeninggrannysgardenpages.blogspot.com/p/houseplants-amaryliss4-amaryllis-did.html

Grow lights and grow light systems are popular gifts this year. That may be because many places have legalized growing pot or because many people want to grow fresh herbs and greens inside. There are a lot of choices on the market now. You can choose LED bulbs that fit a variety of fixtures or buy a system that includes lights, fixtures and planters. There are grow “tents” and grow “closets”.  It helps to know what crop the gardener wants to grow before you choose. Larger crops like pot and tomatoes need larger systems than a system for growing greens on a countertop. 

One note on grow lights.  There are sodium halite grow bulbs on the market that produce intense light for growing things like pot and tomatoes. These are much harder to install, usually requiring an electrician, and they are a fire risk as they get very hot. I would not buy them as a gift unless a gardener has told you they want them.

Garden art, décor, fountains and the like are tricky to give as gifts unless you are sure you know the gardeners taste, or they have hinted to you they want a certain piece. If a gardener has a preference for a naturalistic theme, they may not appreciate a plastic statue of a boy peeing.  That said, wind spinners and fancy wind vanes are popular garden art now, as are bottle trees, and leaping glass or china fish. Rain chains also remain popular.

Tools are always a good gift for gardeners especially if they are high quality tools.  Ergonomic tools for gardeners with arthritis or other disabilities are a good gift.  Here too, it pays to know what tools the gardener already has and listen for hints about what they need.

Garden gloves are usually a good gift.  Buy good quality gloves that will fit the gardener’s hands. Every gardener can use back up gloves, even if they have a pair they love. Other gardening clothing, like hats and aprons, can be a good gift too.

Garden books or a garden class can be great gifts.  Can you buy your gardener a ticket to a garden expo or seminar, or pay for a Master Gardener class?  Make sure the event will fit into the gardener’s schedule.  If you have lots of money to spend on the gift you could book the gardener a trip to a famous garden.
 
Things for the birds and bees may be appreciated by your gardener.  A complete bee keeping start up can be an expensive gift, but you can buy homes for native bees and bee feeders for a reasonable cost.  Bird houses and feeders are good garden gifts too.

If you still need those garden gifts better get shopping.
  There’s still time to order by mail if you hurry. 

Is an artificial tree better for the environment?

One of the biggest environmental myths is that buying an artificial Christmas tree is somehow saving the environment.  The mistaken theory is that you are keeping a tree from being cut down each year you use one of those awful plastic trees.  What some people don’t realize is that Christmas trees are a crop, grown to be cut, and that they are constantly being re-planted.  Over 95% of Christmas trees sold come from tree farms and are not harvested from the wild.

It takes water and some protective chemicals to grow great Christmas trees but it takes a lot of far more harmful chemicals and water to make that plastic tree.  Dangerous chemicals are used to make the fake trees including polyvinyl chloride (PVC) and lead.  The manufacturing of products from PVC releases dioxins into the environment.  Dioxins accumulate in fatty tissues and become more concentrated as in the tissues of animals high in the food chain, like man.  There they cause cancer and other dangerous health problems.

While many of those toxins remain in China- where most, (85%), artificial trees are produced by minimum wage workers, some does make it into our food supply.  Some chemicals, like lead, may be given off as the plastic slowly degrades and reacts to other environmental chemicals and those go right into the air of your home, where the tree is displayed or stored.  In fact, California requires plastic Christmas trees to have a warning label about lead poisoning.

Fake trees sometimes have actual wood “trunks” or other parts and this wood from China has been responsible for at least one exotic pest, a wood boring beetle, to be brought into the US and has the potential for other pests to be carried in the plastic tree shipments.

Plastic trees cannot be recycled; the plastic used in them is not commonly recycled.  A real tree will break down in the environment and do good instead of harm like the plastic trees leaching chemicals into the air and soil.
 Are you worried about fire safety with a real tree?  Thinking a plastic tree is safer is wrong, fire statistics say its faulty wiring that causes most Christmas tree fires and both real and fake trees will ignite.  Make sure to always keep a real tree in water.

The production of Christmas trees uses land in a sustainable way and fewer fertilizers and pesticides are used on tree crops than conventional crops so it’s good to encourage the local tree farmers.  While trees are growing, they release oxygen, moderate the temperature, filter the air and provide homes for wildlife.  Help our environment, buy a US Christmas tree and help keep dioxins in China.

It takes a little more time and effort to use a real Christmas tree each year, but the smell alone is worth it.  And who doesn’t want to do good in the holiday season?  Many Christmas tree lots are run by charitable organizations who use the money they make to help people in need, so you help people while you are helping the environment

Snickerdoodle cookie bars

I made a batch of these this weekend and they were delicious as usual.  It’s an easy recipe and the spicy goodness works well as a holiday gift or dessert.  I like bar cookies because putting all those individual cookies on pans takes a lot of time.

The biggest thing to watch with these snickerdoodles is getting them baked without overbaking.  The sides should be lightly browned but still a bit soft in the center when done baking.  Cut these while they are still warm but let them finish cooling in the pan.

Ingredients

1 ½ sticks (12 tablespoons) butter at room temperature
1 cup + 2 tablespoons sugar
½ cup packed brown sugar
2 eggs
2 teaspoons vanilla
2 cups flour
1 teaspoon baking powder
3 teaspoons cinnamon
1/8 teaspoon nutmeg
1 cup butterscotch baking chips

Directions

Preheat oven to 350 degrees F.  Spray a 9 x9 or 8x8 pan with pan spray.

Combine the flour, 2 teaspoons of the cinnamon, nutmeg, and baking powder.  Blend well, set aside.

In another bowl cream the butter, the brown sugar and 1 cup of the white sugar until fluffy with electric mixer.

Add the eggs and vanilla and mix well.

Slowly beat in the flour mixture until a soft dough forms.

Spread the dough evenly in the pan.

Mix the remaining cinnamon and sugar together and sprinkle evenly over the top of the dough.

Bake about 25-30 minute, watching carefully near the end of the baking time.  You want lightly browned, firm sides and a slightly soft center.

Remove pan from oven and sprinkle the butterscotch chips evenly on top immediately.

Let the chips soften a bit – about 2 minutes, then spread them out evenly with a knife to cover the cookie bars.

Cut the snickerdoodle bars into the sizes you prefer while still warm but let the bars cool in the pan for at least 10 minutes before trying to remove.

If left overnight the bars will be a bit firmer/drier. To store cover tightly. 

“Now is the time of fresh starts
This is the season that makes everything new.
There is a longstanding rumor that Spring is the time
of renewal, but that's only if you ignore the depressing
clutter and din of the season. All that flowering
and budding and birthing--- the messy youthfulness
of Spring actually verges on squalor. Spring is too busy,
too full of itself, too much like a 20-year-old to be the best time for reflection, re-grouping, and starting fresh.
For that you need December. You need to have lived
through the mindless biological imperatives of your life (to bud, and flower, and show off) before you can see that a landscape of new fallen snow is THE REAL YOU.
December has the clarity, the simplicity, and the silence you need for the best FRESH START of your life.”
