Cannas – Transplanting Tips
Q: I planted ten different cannas which are all blooming, anywhere from three feet to six feet tall. I want to transplant the smaller ones. Do I have to wait for the blooms to finish?
A: The cannas will be happier if you wait until frost has killed the leaves. At that time you can cut the stems just above the soil surface and dig the thick roots from the ground. Cannas are usually, but not always, winter-hardy in the Atlanta area. You can store the roots wrapped in newspaper until planting time in spring. Or you could plant the roots where you like and mulch heavily.
