I have been gardening for several years, but this is the first time I've collected my own seeds. Instant addict!!! I agree with someone else who said you start to look at flowers and plants in a completely new way. I'm obsessed.
Anyway, my question is, do the seeds I collect have to be sown within the next growing season, or do they "expire?"
Thanks for taking the time to share your knowledge with newbies like me.
PS love your writing style, Critter! I've read tons of your articles :)
Most seeds are "good" for at least five years if stored properly. Room temperature works fine, but a hot attic wouldn't be good. If you're storing them in plastic bags, make sure they are completely dry before sealing them up (or you'll have moldy seeds). A lot of seeds are good for much longer than 5 years, although their germination percentage may drop a little. There are a few exceptions, but for the most part there's no rush to sow your seeds immediately.
