Frozen seeds?
 

I am wondering if my germination problem is due to the seeds sitting out in the mailbox and getting too cold...like frozen? Would this kill off even fresh seeds? I don't want to even think that way but I have had some germination problems with "Black from Tula". Anyone experience this?

I have kept seeds in freezer with no problems.

I find 100's of "volunteers" growing each spring in my garden and compost pile.

It stays below freezing here for weeks on end so it's safe to say that tomato seeds exposed to freezing for a few days wouldn't hurt them. :wink:

Storing them at high humidity in a warm environment is much more likely to affect germination over freezing. Perhaps they are old?

Carolyn and others here have a trick that sometimes wakes up old seeds. I'll let them post the info.

Yes Mischka there are some ways to wake up old seeds but when Sue talks about them being in her mailbox I didn't get the sense that they were old.

Were they Sue?

Were they purchased or traded seeds and do you know the seed age?
