I sowed hardy perennials in late Sept/early oct. some have germinated and are tightly packed in the pot. I think it is too late to prick them out. Will they survive in my plastic greenhouse? I have each pot in a ziplock freezer bag which is open now, but I can close over the winter. I have overwintered older seedlings(from summer sowing) in plastic boxes with snap lids before. this is my first attempt at autumn sowing. Should I do anything else?
