Do I Have to Dry My Canna Plants for Winter?

Problem

• Gardeners that live in U.S. Department of Agriculture plant hardiness zones below 8 should remove the canna rhizome from the soil before the first hard freeze. The rhizome will freeze and rot if left in the soil.

Solution

• Dig up the rhizome in the fall. Allow the rhizomes and roots to dry on the soil for three to four hours.

Considerations

• It is important to not let the canna rhizomes freeze over the winter; store them in an area that remains below 50 degrees Fahrenheit. An unheated garage, connected to the home is an ideal storage area.
