Re: Frozen seed

Freezing under outside conditions in no problem in itself(I'm assuming
these are not tropicals?) however freezing in a household freezer can be
a problem due to rapid rates of change that the seeds can't compensate
for, resulting in ruptured membranes. I would be more concerned about
cooking them on the first warm sunny day this spring, the temps in a
closed bag can soar to well over 100 deg quickly. Placing them in a
nearing frame or shaded cold frame might be a safer idea. Shaded cool
poly houses also work well.

seedlings a year plus a bunch of germination research, so we too have a
lot at stake.)
