Kim, I have tried several methods over the past few years, but
the method this past season gave me the best germination
rate. More than I wanted were 100%. Of course, this is for this zone, which
may or may not make a difference.
First, the gathered seeds were allowed to dry for 2 days.
Second, the seeds are placed in a small plastic bag with
a tiny piece of folded paper towel dampened with a 10% peroxide
and distilled water solution. The refrigerator is set to 39 degrees
and the seeds are placed in the bottom crisper. The paper towel
is placed in the top of the bag, away from the seeds. I put all the
small bags of the same date into larger bags, then the next later
dated bags into larger bags, etc., just to keep up with when they
might be germinated, and checked them often. So, a really lot
of seeds fit into the crisper. The seeds stayed plump.
The seeds began to germinate (thought I would have more time to plant)
in about 3 weeks in the refrigerator, and as they did, I planted all
the seeds in the bag. I heated the potting soil in the microwave
to avoid fungus gnats and bacteria, which appears to have done the job,
as I did not have damping off or gnats from the potting soil.
I plant seeds rather shallow, one-fourth to one-half inch beneath
the soil depending on the size of the seed. Then place plastic wrap
over the pot, and secure it with a rubber band. The plastic
wrap keeps the soil moist, so no need to water. I have had no
damping off with the use of the plastic wrap. When I see the
green spikes of the seedlings coming up, I remove the plastic wrap.
Did a comparison of the microwaved and not microwaved soil
the year before, and definitely saw a difference. The seedlings
will stay in the house until mid April to mid May usually. If temps permit, they
are then taken outside, and acclimated to the sun slowly depending on the weather, and
planted into the beds prepared for them.
Lots of ways to do this with good results, as others have found
what works for them as well.
