I no longer winter sow due to critters disturbing my seed containers. For the past several years, I have had great success sowing indoors under shoplights outfitted with UV bulbs.
For these past several years, all I have done to give perennial seeds their stratification period is keep the seed packages in the crisper drawer of the fridge in an opaque, sealed container. Everything I read however, says you have to put the seeds into some type of medium - or at the very least wrapped in a damp paper towel in a sealed baggie.
I have never done this and it's never been a problem.
My question, however, is due to my recent purchase of certain perennial seeds that were a bit uncommon and expensive, and I don't want to goof anything up.
Is just putting the sealed seed packs in the fridge for about 8 weeks not enough to "stratify" the seeds or MUST I open the packs, put the seeds into some type of growing medium, wrap in damp paper towels, etc?
Apologies if this is in the wrong forum. Thanks in advance!
