“I seem to be having trouble finding information regarding container gardening with butterfly bushes. Is it worthwhile to attempt, and how do they fare? Emily Rumpf from Cato, New York asks.

Melinda states that containers can be used to grow butterfly bushes as well as other trees, shrubs, and perennials. Plants that are at least one zone hardier than your area will give you the best chance of surviving the winter. You will need to offer additional winter protection in colder climates.


After the soil has thawed and dried, move the plants inside an unheated garage and water them as needed. Alternatively, place wood chips over the roots and encircle them with soil bags or another kind of insulation. Another choice is to submerge the pot in a sheltered, unoccupied area of your garden.
