Dwarf Butterfly Bush
I have several dwarf butterfly bushes in 10-inch pots. They have a 2 ft. spread. I live in Zone 5. I would like to keep these in pots for next year as well. How should I over-winter these potted bushes?

Make sure that for the winter months they are in a sheltered location, like near a foundation. This will reduce the chances that the cold will kill them.
