Growing flowers and vegetables from seed can be one of
the most rewarding gardening experiences a person can
have. You can do it alone, or with others. Now is a
great time to get a head start on Spring by planting
seeds indoors. No matter were you are, starting your own
seeds now will give a head start and allow you to try
new varieties. What do you need to start?
Here are some basics:
- Seeds
- Containers
- Soil (growing media)
- Water
- Light
- Warmth
Seeds
Choose the type of seeds by looking back on your past
gardens. What are some of the plants you have had the
most success from? What are some plants you might like
to try? Are there some things you have not seen before
that looks interesting? Browse selections in seed
catalogs and make a
list. A few seeds are better to plant directly in the
ground where they will grow through the season. Some
examples are corn and root crops. Most flowers, herbs
and vegetables do well when started early and
transplanted.
How many packages do you
need? Most packages contain more seeds than you might
need for a home garden and since the seeds are sold by
weight, the smaller the seed size the more per package.
What about seed you have from previous years? The simple
answer is fresh seed has the best chance of growing. If
you have some seed from previous years, you can do a
simple germination test by placing a few of the seeds in
a clear quart jar with a damp paper towel, close the top
and place in a warm (60-70f) spot with bright light.
Most good seeds will sprout in about 10-15 days. You can
usually store unused seed for the next season if you
keep it in a dark and dry location.
Containers
Seed
starting does not require a large container. In fact,
shallow containers are generally best. Low rectangular
containers called trays
or flats are well designed with enough space to
start many seeds. You can recycle old trays or
containers, but they should be cleaned and treated to
avoid contamination from diseases. An easy way to treat
your container is to apply a simple mixture of household
bleach and water. In addition it works best if you cover
the container with a clear
dome. Soil
Perhaps the most important thing after choosing seeds is
the soil selection. The selection of the right material
will go a long way toward your success. First, do not
use used soil. Start with vermiculite, sand and (or)
sterilized potting mix. There are many different recipes
for seed starting, but one that we like is to use ½
washed river sand and ½ vermiculite.
Save a small amount of sand for seed cover.
Water
Before planting, add enough water to make the soil moist
without making it soggy. Misting with hand a held
sprayer or a Garden
Coil will work best. It will be necessary to add
water later and misting will be easiest.
Light
There is no equal to sunlight, so wherever possible, use
the brightest natural light you can. If you have low
light or very short days, consider using a lighting
system. The light needs to be placed very close to
the surface of the container which makes fluorescent
light a good choice because it does not get as hot as
incandescent light. To save energy, try to use the
lighting system to make the daylight hours longer and
use it just before sunset for three or four hours.
Warmth
All
seeds germinate best with warm temperatures and bottom
heat is best because it helps draw the roots down
through the rooting soil. Using a heating
mat can make the seeds germinate more uniformly and
quickly. If you do not have a heating mat, find a
location were the temperature remains stable around
60-70f.
Planting
Fill the container with the moist mix and press it down
firmly with a flat board. To prevent disease, lightly
coat the seeds with organic
garden dust by placing a tablespoon in a bag, add
the seeds and shake vigorously. If the seeds are very
small, mix them thoroughly with a cup of sand. (Note:
though they can easily be planted directly in the
garden, peas and beans should be soaked in water for
about 24 hours before seeding) Sprinkle the seeds over
the surface and press them in with the board. Cover the
soil with just enough sand to hide the seed. Mist
lightly with water. You do not need to add fertilizer,
that will come later when you transplant the seedlings.
Place the clear dome over the top and if you have a
light and mat, plug them in. Germination can begin in as
few as 3-5 days or as long as 2 weeks. Be patient and
make sure the soil stays moist to the touch. Keep the
dome on until the seedlings have grown to about one inch
tall, then it can be removed. When your seedlings are
about 1 ½ to 2 inches tall, they can be transplanted
into individual containers 3-4 inches in size for
planting later.
Time your seeding to be
ready about the time the weather allows you to plant in
your zone. Be sure to make notes about the varieties,
timing and names. Experiment with at least one fun plant
like Garlic
Chives.
