Any advice on overwintering seedlings- I have neither a cold frame nor greenhouse. I have some Hollyhock seedlings that I started in August and moved once into community pots. They don't seem to be growing very much at all(barely have their second set of leaves), so I don't know if I messed up by moving them; they have very long roots even as young seedlings. I also have some trumpet vine seedlings in a community pot; I don't know if I could just mulch them well and leave them there for winter(I generally will sink pots in the ground,too). Any thoughts on overwintering these two ?
