Growing Herbs from Seed
- Spring
There are a great many reasons for starting your own herb plants
from seed. Most gardeners are first prompted to venture down this
road by this motivator: necessity. How many of you have wished for
the perfect herb to fill in that one last spot in the garden or the
perfect shade of pink in your flower border and then have gone to
your local garden center only to find out that it is not available
locally? Economics is another motivator for starting your own seed.
Plants, especially exotic, can be expensive even to buy just one and
often one is not enough. Starting plants from seed often gives us
more plants than we need. Quality is another motivator for seed
starting. Often the plants found at the local big box stores have
been sitting around at the mercy of whoever remembers to water it.
Starting plants from seed at home insures that plant health is
controlled which gives the plant a good start for a long life.
For
me, winter begins when the onslaught of seed catalogs hit my
mailbox. I am like a kid in a candy store with wonderland stretched
out in front of me. And all of this in the luxury of my nice warm
easy chair. When the catalogs start rolling in, I take a few minutes
with each one and circle whatever suits my fancy with a black magic
marker. I go through all of the seed suppliers since there is a
likelihood that one of the suppliers has the perfect basil or
oregano that I don’t have yet. I then whittle down my selections to
the chosen few and place the orders. Place your orders right after
the first of the year because by March most supplies are starting to
dwindle.
Finding the space to start your seeds could pose some logistic
problems, so before you actually begin, decide where you plan to
keep the trays. Seeds need warmth and moisture to germinate and once
germinated they will need light. My suggestion is that if you don’t
have plant lights or fluorescent lights use what you have in the
house. Seed germinates between 65 and 70 degrees Fahrenheit. The top
of the refrigerator or the top of the TV. or a warm windowsill are
all good places to start the germination process. Before you begin
your seed starting adventure gather a few key items. Containers can
be of various shapes and sizes. From propagation trays with domes to
clean egg cartons, these will work as long as they can hold a little
seed starting mix and can handle a little moisture. They must be
clean and free of contaminates. Wash the trays with one part Clorox
to 9 parts water and rinse well. As with anything else in life the
preparation of growing medium for seeds can be as simple or as
complex as you want to make it. We chose to be as simple as possible
with our growing mix opting to pick up several bags of the Jiffy
like mix at our local home improvement stores. Pre-moisten your
growing mix before using will kept the dust down and make sowing
those tiny, tiny seeds a whole lot easier.
Most
seeds can be sown straight from the packet, but on occasion seed
jackets are too tough and germination is virtually impossible. By
chipping, nicking or soaking the seeds for a period of time in warm
water, the jackets will more likely open up and receive the moisture
needed to germinate. Most seed companies give you some information
about the best method of preparation so read the back of the package
carefully.
Eliminate confusion at sprouting time by marking your trays with its
contents. Little white tags with name of seed, when sown and any
other pertinent information can be written down. Tamp down the
medium and level off in the container. Make indentations or rows for
the seed keeping the depth according to package instructions or your
own experience. Either with a pinch of two fingers or a gentle shake
of the package those tiny seeds will be on the growing medium. Tamp
down the seed to make contact with the medium. Cover your seed trays
with plastic wrap or plastic domes to retain moisture. Place under
growing lights or on top of refrigerator. Most seeds will germinate
in 7-10 days with some exceptions. There are some herb seed that
requires refrigeration before sowing. Again, experience and a little
research will give you the information needed to reach a high rate
of germination.
Once
germination has occurred take the domes and plastic wrap off the
seedlings. Place seed trays under grow lights or near a sunny
window. Turn the trays often to insure that the seedlings are
receiving enough light and watch for drying out which occurs
quickly. Damping off occurs when the stems of the seedlings rot at
the soil surface. The seedling falls over and dies. Water the
seedlings by sitting the tray in a pan of water or the sink and let
the moisture absorb from the bottom. Once the herb seedlings have a
true set or their second set of leaves it is time to transplant to
their new homes. Pot up the new herb babies in clean and sterile
pots. Use a potting mix that is friable and light. Poke a small hole
in the potting mix. Gently pry your seedling out with a popsicle
stick under the roots and gently place into hole in potting mix.
Lightly tamp soil down and gently mist. Water until well
established. Excerpt from “Starting Herbs from Seeds” by Michele
