Winterize potted plants
I'm running out of space. I've started to planting in pots. I've researched online. Everyone says plants should be 2 zones colder in hardiness and put close to the foundation. Is that ture? Some even say put them in the shed. My basement is 3/4 finished. I have no garage. I check the shed's temp, it's as cold as outside. I have a deck warps around the unfinished part of the basement. Last winter I winterized potted peonies under the deck. It was a success.
So which one is the best location for winter protection, close to basement, the shed, or under the deck?
