Hi Gardeners
Tulip Orca-2015

Ah, what a difference a week makes. Since I last wrote we had 8 inches of snow that has now mostly melted. Today it’s 70 degrees and humid.  As we drove down the curvy, hilly, white pine lined road to our voting place this morning the sun was peeking through the fog.  We vote north of our home in the “antique” village of Kingston, which is a sleepy town surrounded by beef farms.  I love small town voting, where the wait is non-existent most times and you run into the neighbors.

After voting as we drove home I noticed the Canada geese were everywhere, every snow melt puddle and half thawed pond.  Some are resident geese, but others are journeying north, I have heard and seen flocks headed that way the last few days. The red winged blackbirds are here in force now, they were singing like crazy this morning.  Soon we may be hearing frogs. 

The weather looks mild for at least the next week, but with lots of rain chances.  I looked back at last year’s weather and it was similar last year, maybe not quite as warm.  But at the end of March we had two pretty good snowfalls last year although they quickly melted.  I have spring fever and I am wishing I could do some work outside but my bum arm and the wet soil are pretty much limiting my options.

I did start some seeds last week – well actually I transferred them from the wet towels I sprouted them on to pots.  And here is my epic seed starting "fail". I had some new seed starting soil from Gardeners Supply to trial- and it’s great by the way. I set the open bag on the shelf in my home office, close to my canaries, to keep it from Gizmo, my dirt loving pup. Evidently seed got spilled into the open bag- a lot of seed. It was strange but I didn't notice this when I started some seeds and transplanted some seeds sprouting on paper towels last week. But I sure noticed in the last few days. Evidently canary seed loves Gardeners Supply soil. I had to very carefully pull out the sprouted canary seed- it was very thick- hoping I didn't disturb the other seeds. The house birds and the chickens are getting a big pile of sprouts. I checked the remaining soil in the bag and sure enough seeds were even growing out tiny holes in the bag. It was a lot of seeds- I still can't figure out how- maybe a husband trick?

Canary seed mess.
This issue is primarily about the various aspects of selecting and starting seeds indoors.   I don’t start a lot of seeds inside anymore; I just don’t have the room.  But every spring I do manage to start some, usually experimental things or hard to find plants.  Even if you don’t have a lot of room, a lot of experience or time, I encourage you to at least try starting a few seeds inside, as you wait for better weather.

Should you start seeds inside?

It’s a personal choice as most people can find the plants they want in local stores or through on line or catalog sources.  But sometimes rare varieties may be hard to find, or very expensive as plants.  For some people seed starting can be an economical way to get a lot of plants, especially if you re-cycle pots and get seeds by swapping with friends.  But if you are a person who just wants 2 or 3 tomato plants starting them from seed will not save you money.

Many vegetable garden plants and annual flowers are best started where they are to grow outside.  There’s more about which seeds to start inside or outside later.  Some plants don’t reproduce well by seed.  But there are many things you can start from seed and it’s a fun thing to do while you are waiting to get outside to garden.  Children love to be included in seed starting.

If you are new to the idea of starting your own seeds inside then read this blog issue for guidance and then get your hands dirty.

Selecting your seeds

Before you can start seeds you have to have seeds.  New gardeners are often confused by all the advice thrown at them by other gardeners.  Buy organic, choose hybrids for vigor, choose heirlooms for best taste, you must choose open pollinated, buy seeds grown in your growing zone, don’t buy GMO seeds and so on.  Here’s some definitions and information that may help you sort through all that advice.

Defining organic

One of the problems with the organic growing movement is how people define organic.  If you take the word organic for what it means in the agricultural sense - growing things without synthetic chemicals, both pesticides and fertilizers, then certainly hybrid seeds can be grown organically.  Any type of seeds can be produced organically.  The parents of hybrid seeds can be grown organically so the word hybrid should not determine the organic status of any seed.

Recently some people have begun to assert that the label organic should also mean seeds that were produced by plants that were not “genetically modified” as well as being grown without synthetic chemicals.  But technically GMO seeds could be produced and grown organically.  Its unlikely home gardeners will have to face this problem however, see the definition of GMO below.

It can be hard to raise good quality parent plants without pesticides.  This is especially true of some vegetables we grow from seed because the parent plants must grow until their second year to produce seeds.  Organic seed generally sells for more than conventionally grown seed, although the costs have come down on popular items.  If you don’t see that seeds are labeled “organically grown” they are probably conventionally grown, and that means at least some pesticides or synthetic fertilizers were used on the parent plants.

Can you grow organic food or flowers if the seeds weren’t grown organically?

Some organic purists, and people who want to be certified as growing organically, insist that the parent plants that produce the seeds they are going to grow were also grown without any synthetic chemicals. However if no seed treatments are applied to the seeds of plants that were not grown organically then you can grow organic produce or flowers from those seeds if you follow organic practices.

The problem with “non-organic seeds” is if the seeds themselves were treated with one of the neonicotinoid pesticides.  Many types of seeds are treated with these products to prevent insect damage in storage.  Since the seeds take up these pesticides the neonicotinoids also protect the seedlings as they begin to grow.  As the plants get older, if no neonicotinoid pesticides have been applied since the seed treatment the amount of the pesticide in plant tissues continues to decline.  However studies have shown that a small amount of pesticides can remain in plant parts, including pollen and nectar for at least a year.

Neonicotinoid pesticides are very safe for humans, other mammals and birds and that is why their use is so popular.  The problem is that along with harmful insects neonicotinoids can kill or weaken pollinators and other helpful insects.  There is ongoing research on this subject, but it seems that seed treatments or treating seedlings and nursery starts with neonicotinoids can affect pollinators when those plants bloom, weeks or months later.

Plants grown from seed treated with neonicotinoids will not harm you, only pollinators and other insects.  If you are going to plant things that you consume before they bloom, such as lettuce, carrots, beets, broccoli and so on then the infinitesimal amount of pesticide left from a seed treatment should not be any problem. If you used organic growing practices your food is very, very close to organic, although legally you may not be able to label it as such.

Plants like trees or shrubs that will take several years to bloom from seed will not have any pesticide residue left to harm bees. Whether you choose to grow neonicotinoid treated seeds for plants like beans, sunflowers, squash and flowering plants attractive to bees that bloom the first year, is a personal choice.  At this time research suggests there may be some damage to pollinators with some species of plants whose seeds were treated.

There are occasionally other types of seed treatments.  Fungicides are sometimes applied to seeds to prevent rotting in cold wet soil.  These do not persist long in plant tissue, and if you follow organic gardening practices the plants produced from the seeds are, for all purposes, organic and not harmful to you or pollinators.  Seeds are sometimes treated or inoculated with natural soil mycorrhizae and microbes.  Since the products occur in natural conditions they should be considered organic.  Seeds that are pelleted for easy handling are generally coated with a clay product that is totally organic and safe. 

If you are worried about planting seeds that could harm pollinators or want totally organic seeds there are now many companies that offer either organic seed or seed produced conventionally that is not treated with neonicotinoids.

Defining GMO

The term genetically modified should be applied to plants or animals whose genes are altered in some way that can’t happen naturally such as when we use a virus to put animal genes into plants or genes from plant species that can’t cross naturally with each other.  These genes will then carry into future generations if similar plants are bred together and could be carried to other similar plants in a natural cross.

There are many field crops on the market that have been genetically modified, wheat, corn, soybeans and such.  But very, very few garden plants have been altered in this manner.  Your hybrid sweet corn, cabbage, marigolds and so on generally are the result of good old fashioned plant sex.  The very few genetically modified garden crops are expensive and generally available only to large commercial growers.  

The contamination of plants by stray pollen from genetically modified plants can happen to all varieties of plants not just hybrids.  But in garden seed that possibility is remote at best.

Defining hybrid

A hybrid seed is the result of crossing two purebred varieties of plants.  This usually happens in the old fashioned way, by insects or wind carrying pollen from one type of plant to another.  Plant sex.  If you plant a row of Blue Lake beans next to a row of Straight Arrow beans and bees carry pollen from one to another, the beans produced on those plants are hybrids.  The purebred parents and the resulting seeds can be grown without synthetic chemicals so yes, hybrid seeds can be organic.  

Hybrids happen between plants all the time, without man interfering at all.  Every time you plant 6 varieties of tomatoes in the same garden you are creating hybrid tomato seeds.  You probably don’t save and grow the seeds the next year and there is a good reason for that.   Those six types of tomatoes combined and produced all kinds of hybrids or crosses. Some of the combinations are great, some mediocre and some awful.  If you planted those seeds next year you wouldn’t know what you would get, although it certainly would be tomatoes.

When man discovers two purebred varieties of plants that when crossed produce something good, he may set out to deliberately re-create it by hand pollinating the plants or by removing the anthers (pollen producing parts) from one variety so it can only be reproduced by another variety grown nearby for that purpose.  He can discover which plants combine well by experimenting with hand crosses and carefully keeping records of the results.  Then when he finds combinations or hybrids he likes, he can re-create the cross.

Hybrids usually have something known as hybrid vigor.  The offspring of that first cross of 2 purebred parents are generally more vigorous and healthy than the offspring of pure bred parents.  This happens because when we mate purebred animals or plants to another of the same pure breed generation after generation we start concentrating certain genetic material and genetic variability, the thing that lets plants or animals adapt to changing conditions, is lost. Over time a purebred strain tends to become less able to reproduce successfully, loses vigor and is more susceptible to disease.

Just as we know what we are getting when we mate a purebred plant to a purebred like it, when we save the seed and plant them, we can know what to expect when we cross 2 different varieties of the same plant.  Thus we can name these crosses and people can confidently plant them and know what to expect.  Sometimes we can even successfully cross two distantly related species, such as the plum and the apricot and get good results.

If you save the seeds from hybrid plants the third generation will recombine genes in many ways and you will get all kinds of plants, and probably not ones like the parents.  But you could get something better than the parents, you never know.   Most home gardeners don’t save food plant seeds from their own plants to grow the next year anyway.  They don’t have room to separate plant varieties and can’t generally control what the neighbors are planting and plants can spread their pollen some distance with the help of the wind and insects. 

If you don’t save seeds to plant the next year then don’t worry whether you choose hybrid or open pollinated seeds.  There are far more varieties of hybrid vegetables and flowers on the market than open pollinated.  You have a better chance to find highly productive, disease resistant seeds among hybrids.  Whether seeds are hybrid or open pollinated does not influence their flavor or nutrition, despite many strident claims.  Some hybrids can also be considered heirlooms, since they have been around for a very long time.

Defining open pollinated

Purebred varieties of plants are called open pollinated.  The only advantage they have is that you can save the seeds and if you have carefully isolated that variety of plant from similar plants, the seeds you save and plant next year will produce plants like the parents.  Open pollinated plants don’t always taste better than hybrids nor are they more nutritious.  They may be less vigorous than hybrids and more susceptible to disease.

It’s a great thing to save old breeds of open pollinated plants. We need the purebred lines to produce new and better varieties of plants and preserve genetic diversity.  But if you are just a gardener trying to grow good, safe food you don’t need to worry about whether your seeds are open pollinated or hybrid.  If you don’t use synthetic chemicals in your garden then you are growing organically, regardless of what seeds you planted.

So choose the hybrid seeds that appeal to you and don’t worry that you are violating some great organic principal.  If you look, you can find hybrid seed that was grown organically if that’s important to you. Expect to pay more than for hybrid seeds grown conventionally.   If people choose organically grown seed more often then more will be grown and fewer pesticides will be used over all.  But if you follow good organic garden practices any seed you buy that hasn’t been treated with neonicotinoids can be grown organically.

Defining heirloom

The definition of heirloom varies from company to company, gardener to gardener.  Some insist only open pollinated plants (see above) can be heirlooms.  Some use a hundred years as a distinct variety as the definition, some use 50 years- it’s all over the map.  But the common thing is that the plant variety has been around for fifty years or more.

There are certain groups of people that will tell you that heirloom or heritage varieties are the only ones you should grow because they taste better or are more nutritious or are more fragrant or attractive to bees.  But that is just nonsense. 

Some heritage/heirloom varieties may taste better than some modern varieties but taste is highly selective anyway.  There are perfectly delicious modern varieties of plants like tomatoes and beans too.  Some of these modern varieties are more nutritious than older ones.  And modern varieties are often more disease resistant, which keeps you from having to use pesticides as often to produce a good crop.  Modern varieties, especially hybrids, often produce more food in the same space and they adapt to various climates and conditions better than some heirlooms.

In flowers some new varieties may have lost their scent, some may have doubled their flowers, changed the flower color or modified the flower so it’s not as attractive to bees, but many modern varieties are also more fragrant, or more attractive to pollinators also.  Just like vegetables, modern flower varieties are often more disease resistant or have other good traits older varieties don’t have.   You have a choice of what to plant. 

There is a great need to keep diversity in the genetics of all crops, whether or not they are flowers or vegetables.  It can be great fun to grow plants your grandmother grew.  It’s wonderful to include some heirloom varieties of vegetables, fruits and flowers in your garden, even more wonderful if you can save seeds and pass them along.  But don’t feel guilty or deprived if you don’t use all heirloom plants in your garden.

Just because a variety of plant is old or open pollinated doesn’t mean its superior to modern varieties.  Some are, many aren’t.  People have been improving plants for thousands of years.  There are trade-offs for many choices.  An outhouse may save water and be more environmentally friendly than a flush toilet.  But given the choice most people will pick the flush toilet.

What to start from seed

Any plant that produces viable seed can be started from seed.  But be aware that some seeds won’t look like the parent plant when grown, especially if they are seeds saved from hybrid plants or from plants like apples, which don’t allow pollination from a similar variety.  Some plants resent transplanting and are best started where they are to grow and some will do fine started in pots or flats. And other plants started from seed will take a long time to grow or to produce flowers and food so they are generally purchased as plants, although you can start them from seeds if you like.

In the vegetable garden these seeds are generally started in the ground; carrots, beets, leaf and romaine lettuce, spinach, beans, corn, and peas. These plants are started indoors or purchased as small plants; tomatoes, peppers, eggplant, cabbage, broccoli, Brussels sprouts, cauliflower, head lettuce and most herbs.  Dill can be planted directly in the ground and will mature.

Cucumbers, pumpkins and melons can be started inside if they are started just a few weeks before going outside. They should only have one or two sets of true leaves when planted in the garden after all frost danger has passed. Larger plants of these varieties are stressed by transplanting and may not grow well for a while.  These seeds can also be planted outside after frost has passed and the soil is warm and will do well.

Onions can be started as seeds inside, purchased as plants, or started in the ground outside from “sets” which are small onion bulbs.  Garlic is generally planted from “cloves”, small segments of the garlic bulb. Shallots are planted as small bulbs. Chives can be started from seed inside or purchased as plants.  Potatoes are started from small tubers or pieces of cut tubers.  Jerusalem artichokes are started from tubers.

In the flower garden annual flowers like zinnias, marigolds, nasturtium, cosmos, sunflowers, morning glories, and snapdragons can be started directly in the ground or in pots or flats if you wish about 6 weeks before the last frost. Annuals or tender perennials that take a long time to bloom are generally started about February inside or purchased as plants.  These include petunias, impatiens, verbena, calibracoli, begonias, fuchsia, and coleus. 

Most garden perennials can be started by seeds but gardeners will find it much easier to buy plants to set out.  These include things like daylilies, hosta, echinacea, monarda, phlox, heuchera, daisies, coreopsis, hollyhocks, mums, hellebores.  Iris are started from rhizomes (root like pieces).  Canna’s, lilies, dahlias, callas, glads, tulips, daffodils, hyacinths, crocus, snowdrops, all could be started from seed, but most gardeners will want to start with bulbs or corms of these because they will take 2 or more years to bloom from seed.

Roses should not be started from seed unless you are an experienced breeder.  They will not look like the parent plant and many roses are not hardy unless grafted on to a hardy rootstock.  Trees and shrubs can be started from seed but many need to be started from cuttings if you want certain varieties and are best purchased as plants.  All fruits should be started as plants.  Most fruit trees and many grapes are grafted. 

When to start seeds in planting zones 5-6

Seeds to be started in January and February include; Begonias of all types, impatiens, coleus, geraniums, petunias, lisianthus.  Tuberous begonia bulbs, calla lily, banana and elephant ear bulbs can also be started in pots.  Start pansy and viola seeds because they can be planted outside quite early.

In March most types of perennial and bi-annual flower seeds can be started.  Start celosia, diascia, marigolds, nicotiana, snapdragons, salvia, verbena, perennial herb seeds, onions from seed, celery.   If you have a heated green house a few early tomatoes and peppers can be started, don’t start your whole crop this early. March is a good month to root cuttings from over wintered coleus, impatiens, geraniums and begonias.

In April start tomatoes, peppers, eggplant, cabbage, broccoli, Brussels sprouts, alyssum, cosmos, zinnias, calendula, cleome, sunflowers, head lettuce, basil, cilantro, ornamental kale and cabbages.   Pot up canna and dahlia bulbs for a head start. In April peas and leaf lettuce can be planted directly in the garden.  In southern counties radishes, carrots, beets, set onions and potatoes can also be planted in the garden.

In May start, morning glories and moon flower vines, hyacinth bean, nasturtiums,  cucumbers, squash, melons, beans and corn ( for those who like transplants instead of direct seeding in the garden).  By early May most areas can plant radish, beets, carrots potatoes and set onions directly in the garden.  In late May - early June plant sweet and pop corn, beans, squash, melons, cucumbers, sunflowers directly in the garden.

Seed starting tips

If you are a Michigan gardener who is ready to get growing and you are thinking of starting seeds for your garden indoors, here are some things you need to know.

Don’t buy too many seeds. 

Seed catalogs are very tempting and it’s easy to go overboard on seed purchases.  Seeds store easily in a small space, seedlings need much more room.  If your seedlings are too crowded they may not get the light, air circulation and water they need and will suffer.  Consider how much space you have to grow seedlings until they can go outside and chose accordingly.

If you want just a few plants of many varieties maybe a gardening friend will share an order of seeds with you.  Buy the smallest packages of seeds that are available and remember most seeds can be saved for one or two years if properly stored, so you don’t have to plant them all.

Light

Light is the most critical factor in producing healthy seedlings grown indoors.  Seedlings that don’t get the proper light will become spindly and weak and are more prone to disease. Southern facing windowsills may work for some plants, but aren’t ideal.  Most windows facing other directions won’t produce healthy seedlings.

Small greenhouses are ideal for starting seeds but if you start before April in Michigan you will need to have a heat source for chilly nights and cloudy days.  In April seeds can usually be started in unheated greenhouses or cold frames.

If you don’t have a greenhouse you will probably need to grow your seedlings with artificial light, at least as a supplement.  Florescent lights are ideal for beginners starting seeds indoors. LED and CFL bulbs are also good choices but more expensive.  Use grow light bulbs or combine warm and cool type bulbs for the right wavelengths of light to promote healthy growth. Seedlings should have 10 -12 hours of darkness each night.

Artificial light sources need to be close to the seedlings.  They need to be about 6 inches above the plants at all times, so they will need to be adjustable, so you can move them as the plants grow.  Many people hang the light fixtures on chains that can be raised.  Another way to adjust lighting is to be able to lower the shelves the plants sit on.

If you decide to use a south window, rotate the plants every few days so they don’t lean toward one side.  Surrounding the seedlings with reflective material such as foil covered board will optimize the light.

Use clean pots or flats

If you are re-using plastic pots or flats they must be scrubbed in hot, soapy water, then soaked in a solution of 1 part household bleach to 3 parts water for a few minutes, then rinsed well.  This helps prevent disease which can linger on pots and flats from a previous year. Any re-cycled food containers or other things must be washed in hot soapy water, to remove food residue which can start mold and bacteria growing. 

Pots made from paper, peat pots, and other porous material that can’t be washed should be fine unless they have been in contact with plants.  Do not re-use these materials after plants have been grown in them. 

Use sterile seed starting medium.

The best thing for starting seeds is sterile seed starting medium, which can be purchased in most garden shops. It’s not soil but a combination of peat, vermiculite and other things which are lightweight, and get seedlings off to a good start. Some have fertilizer added. 


Home garden soil, compost, recycled potting soil and other things can harbor disease organisms, especially the dreaded dampening off fungal disease.  If you must use them you can sterilize them by moistening the soil, spreading it in a thin layer on a pan and baking in the oven at the lowest heat setting for 30 minutes.  This will smell. Microwaves should not be used.  Cool the soil before using.  Shift this cooled mix through a screen to make it fine enough for seeds.

Always moisten the medium before placing it in the pot or flat.  If you try to water after you plant seeds they will often be washed out, washed deeper or moved too close together.

Follow label directions for planting

If you don’t have a label, look up planting needs in a good reference.  Most seeds are buried about 3 times as deep as their diameter, but some seeds need light to germinate and should just be sprinkled on top of the medium and lightly pressed into the soil.  Most seeds like warmth for germination but some, like lettuce and pansies, won’t germinate if the soil or room is too warm.

The label should give you an optimum temperature for germination and the number of days before you can expect to see seedlings.  It will also tell you how many weeks before you want to plant outside that the seeds should be started indoors.  Don’t start too soon. 

Speaking of labels- don’t forget to label each flat or pot with the plant variety you planted. 

Use bottom heat for germination

Most types of seeds will germinate faster with gentle bottom heat.  This means sitting the pots or flats on a special seed starting mat you plug in, a waterproof heating pad on low, or on top of a warm surface such as the top of your refrigerator or hot water heater.   There are exceptions to the bottom heat rule - such as pansies and lettuce, which germinate best in cool temperatures.

Too much heat can be as bad as too little.  The soil should not be heated to more than 80 degrees F. for most plants.  Soil temperature may be different from air temperature, especially when using bottom heat.  Use a soil thermometer, (usually less than $20 in a garden store), or any small thermometer pushed into the soil to check the temperature.

Seeds don’t need bright light until they germinate.  Once you feel most of the seeds have sprouted, you can then move them into the greenhouse or under grow lights.  After they are growing air temperature can also be cooler.  Most plants will thrive at air temperatures between 65-75 degrees F. in the day and 55-65 degrees F. at night.

Water carefully

Seedlings should be watered from below if at all possible, especially when plants are still small.  This means sitting pots with holes in the bottom or absorbable pots like peat or paper into trays that hold water.  Use warm, not hot water and make sure the water absorbs until the pot surface looks moist.

Don’t over water; it will rot the roots of the seedlings.  Only the very bottom of the pot should be in standing water for more than a few minutes.  Allow the pot surface to dry before adding additional water to the tray.  Paper and peat pots will need to be watered more often as water evaporates into the air from them. Use rain water or distilled water if you can for seedlings. 

Once the seedlings are larger and growing vigorously you can use gentle overhead watering if you like.  But seedlings should always dry off quickly, always water long before dark. 

Transplant or thin

Don’t let seedlings get too crowded, they will be weak and spindly.  You can cut off excess seedlings with a pair of small scissors or gently prick them out of the soil and transplant them. 

When transplanting seedlings handle them only by the leaves.  If you bruise or break the stem the plant will generally die, a leaf can be replaced.  A good time to transplant seedlings is when they have 2 sets of true leaves.  The first set of leaves that a broad leaf plant seedling has are usually two thick, rounded leaves, often with a piece of seed coat still attached.  In a few days additional sets of leaves that look like the adult plant leaves will develop.  In a monocot, ( grasses, lilies, onions, and a few others,) one thin narrow grass like leaf will generally appear first, with additional leaves following.

After transplanting or thinning your seedlings you can begin fertilizing them with a liquid fertilizer unless the potting mix contains fertilizer.  Check the label.  Follow label directions on the fertilizer container for seedlings or if there are none cut the amount for container plants in half for seedlings until the plants are several weeks old and well grown.

With a little care homegrown seedlings will provide you with unusual and rare varieties of plants as well as hours of enjoyment during a cold Michigan winter and early spring.

Recycling for seed starting

All through the winter those gardeners who like to start seeds inside should be saving up items for seed starting.  You don’t need expensive peat pots and plastic flats when you can re-purpose other items you have around.  But before I get into a list here are some things to remember. 

Wash all recycled items that have had food or other materials in them with hot soapy water.  If you are using things that once held other plants or soil first wash with hot soapy water and then rinse with a solution of 1 part household bleach to 3 parts water. This is to kill any disease organisms.

Don’t re-use containers that held toxic chemicals such as strong cleaning solutions, pesticides and so on.  Even washing some of these containers might not remove all traces of the former product.  If washed and rinsed well bleach and laundry soap bottles are safe.

Everything must have drainage.  Paper and thin cardboard pots will generally allow moisture through without holes.  Punch holes in thicker cardboard.  Holes can be easily melted through plastic items with the tip of a skewer, icepick, fork or knife that is heated to red hot on a stove.

Pots, especially paper and cardboard ones, will be easier to handle if they are set in trays.  Deli trays, old pans, used flats, disposable aluminum pans, plastic tubs and food keepers, dish pans, plastic lids off containers and so on can work.
 
Recycled items that can be used to start seeds
Re-closable clear plastic storage bags can have several small pots inserted in them and function as a mini- greenhouse while containing water that drains.  Larger plastic bags can be slipped over trays of pots or flats.  The greenhouse effect can raise humidity and warmth and protect baby plants from drafts.  Open the bags slightly if they are in full sun on a warm day to prevent over-heating.  If excess moisture builds up on the bag sides open the top for a short time.

If fungus gnats hatch from your choice of potting mix the bags help contain them.  It can also prevent things like white flies or aphids present in the environment from reaching the new little plants.  And the bags make moving plants in fragile paper pots easy.

Here are some things to save to start seeds in;  Deli containers, disposable serving pans and platters, plastic and foam cups, butter, cottage cheese and other food containers, small cardboard boxes- (trim them down to a good size if needed), plastic bottles ( also can be cut down) cardboard tubes from paper towels, gift wrap and toilet paper, ( cut into several sections, either set in tray with open bottom or make several small cuts around the bottom and fold a portion inside to make a bottom).  You can re-use cell packs, flats and small plastic pots you bought other plants in.

Paper pots are easy to make from stiff paper, thin cardboard or several layers of newspaper.  They can be planted directly in the soil outside. See the directions here.  http://www.examiner.com/article/how-to-make-paper-pots-for-starting-seeds
Paper pots

DO NOT USE EGGSHELLS for starting seeds.  This is a common spring tip probably because eggs are cheap and we are all thinking about decorating eggs for Easter.  But despite all the folksy lore, eggshells do not break down quickly in the soil and plants transplanted in them generally suffer from root crowding and circling.  Eggshells don’t have room for much potting medium anyway and are tricky to handle and get to stand upright.  Even if you crush the shell as you plant it in the garden or take the plants out they are just not worth the trouble.  And the shell doesn’t break down fast enough to give the plants any nutritional boost either.

Dampening off – seedling disease

If your seedlings suddenly fall over or look like the stem is pinched and blackened they probably have dampening off- a common name for the presence of several fungus diseases that affect plants.  You may also see gray mold on the potting soil surface or on plants.  These fungal diseases are common and the fungal spores can be carried by wind, insects, contaminated soil or pots, humans and many other things. 

There are some anti-fungal solutions that some commercial growers drench the soil with to help prevent dampening off but the home seed starter probably won’t want to use these.  Home remedies of garlic oil, chamomile tea, tea tree oil, red pepper and other things have not been proven scientifically to help and may even cause more problems. Use at your own risk.  These things are used to prevent fungus infection, not cure it.

Here’s a suggestion for those of you who like home remedies for everything that I am going to suggest.  I haven’t tried it yet but I have heard from a few people that it seems to work.  Since there is scientific basis for it, I’ll tell you about it and let you decide if you want to try it.  There’s no guarantee, but it could be an interesting experiment.  Once again, its prevention, not a cure.

Coffee grounds have been shown to have fungicidal properties in several scientific studies.  Used coffee grounds retain those properties.  Sprinkling coffee grounds on the surface of seeded pots or flats might help to keep the fungi that produce dampening off from growing.  I don’t think it could harm anything.  I would use a light even layer for the soil surface.  If you do this and it seems to work for you let me know about it.

Once the seedlings are infected with dampening off there is no cure.   A few seedlings survive dampening off infections but most will die and the disease quickly spreads.  When you notice it remove the plants with the disease and dispose of them.  If the disease is in one corner of a large flat you can try removing that section but if it appears in a small container you should dispose of the whole container of seedlings.  Don’t re-use the container until it is scrubbed and disinfected with bleach.

To prevent dampening off use clean containers and sterile seed starting medium for seed starting.  Let the soil surface dry a bit between watering.  Watering from the bottom and keeping leaves dry can help.  Some professional growers use a light layer of fine gravel (parakeet grit, baby chick grit) or diatomaceous earth on the soil surface after the seedlings sprout to keep the soil surface drier. 

Good air circulation can help.  Many people use a fan blowing gently over seedlings to increase airflow.  This dries the foliage and soil surface. Solar radiation seems to help.  Seedlings exposed to sunlight and not artificial light seem to have fewer problems.  This may be because the suns heat also dries the soil.  But keeping plants too warm can harm their growth, so raising room temperatures may not help, unless your conditions are on the cool side, say below 60 degrees.

Open up plastic or glass covered containers if heavy moisture develops on the sides. If you are using a small greenhouse and water is dripping from the ceiling and sides you need to increase air circulation.  Wet foliage is more prone to fungal infection.

Growing your seeds in several small containers rather than all in one flat or container may keep you from losing all the plants since you can quickly remove the infected containers and make changes if needed to keep other containers from being infected.

Get rid of the Epsom salts!

I think this is a pet peeve, but many knowledgeable garden experts share the same feelings- Epsom salts do not belong in most gardens.  Every time I go to an online site, or read a garden article in the popular press I seem to find someone recommending Epsom salts for everything under the sun- increasing plant growth, chasing away bugs, curing disease, improving flavor, more roses, the of miracle things Epsom salt is said to do go on and on.  The problem is that Epsom salts does absolutely nothing helpful but cure a magnesium deficiency in the soil if you have one, which you probably don’t.

There are no scientific studies that have ever proven any benefit to Epsom salt other than correcting a soil magnesium deficiency.  Despite all the magazine and on line articles, all the testimonials given so enthusiastically, Epsom salt is no miracle cure and can even harm your soil and your plants.  All these sources usually point to each other as the reference in one giant circular myth. 

Epsom salts contain magnesium, which is an essential macro nutrient for plant growth.  When soil magnesium levels are low or magnesium can’t be taken up because of other mineral imbalances, plant leaves may yellow, called chlorosis, and plants may not grow well or produce many flowers or fruit.  But many other mineral imbalances and other things will cause the same symptoms.  Magnesium deficiency is probably one of the lesser causes.

Unless the soil you garden in was used for intensive crop farming, or heavy grazing fairly recently it’s unlikely to be deficient in magnesium.  Sandy soil low in nitrogen, and very acidic is more prone to magnesium deficiency.  A soil test will tell you if your soil is magnesium deficient.  Magnesium may not be available to plants if conditions are very dry or cold, even though there is plenty in the soil.  These conditions do not require more magnesium, but correction of the conditions, which often happens naturally.


Adding magnesium in the form of Epsom salts when your soil doesn’t need it is not only wasteful but it can damage your soil and may harm animals exposed to it.  It can leach and pollute ground water or wash into surface water.  Plants do not suffer much from excess magnesium in the soil, they take up what they need, although growth can slow if the level gets high.  However when you put Epsom salts in a hole dug for a transplant you can burn that plants roots.  When you spray Epsom salt solutions on plant foliage you can burn that foliage.  Too much magnesium in the soil - and soils vary in how much they store safely, can lead to a mineral imbalance and cause other important minerals to become unavailable to plants.

Epsom salt does not chase animals or insects away.  It can make your pet sick though if it decides it likes the salty taste and eats it, or licks too much off its feet.  Epsom salts does not cure fungal or other diseases.  It does not improve the growth of plants or fruit flavor- unless the plant was magnesium deficient.  In fact too much magnesium may cause blossom end rot in tomatoes.

If you notice yellowing foliage on a plant and there seems to be no other reason for the problem it may be a nutrient deficiency.  It may be magnesium that’s lacking or iron or several other nutrients.  It won’t hurt in this circumstance to give the plant a dose of Epsom salts dissolved in water and see if it greens up, which would indicate magnesium deficiency might have been a problem.  If you have a soil test done and the results indicate low magnesium levels you’ll probably be given advice on how to correct the problem.

Other than a magnesium deficiency there’s no reason to have Epsom salts in the garden unless you want to soak your tired feet.  Spread the word and let’s stop polluting the soil and water unnecessarily.  And to stop the he said- she said debate here’s some links to scientific articles that support what I have just written.
