Overwintering In Pots
I am planning on dividing my 6 foot "patch" of undulata albomarginatas during the next month or so to spread out along my front porch. I'm wanting to leave space between them for planting some annuals and seeds in the spring, so I know that means I'm going to end up with more hostas than I have space for.
I have another bed that I would like to move them to, but I need to move other flowers out of the way first and that won't happen until the spring (too much shade for my coneflowers and hibiscus). I would like to put my "extra" hostas into nursery pots (those cheap black plastic ones) until I have space freed up in my bed. Will the hostas survive the winter in those pots? Should I put them in our shed so they don't get too cold? It's just a prefab shed... no heating or anything.
I'm hoping this will work because I'll also be getting some hand-me-down plants from a friend, come spring, and I would like to do just a big spurt of gardening :) Any suggestions would be appreciated. Unfortunately, I don't have any other pots I could use.
