|What is meant by 1-10" water depth over top of pot? Do they require alot of water?|
|Cannas are large tropical plants that grow from tubers. The are available in different sizes, leaf colors (green, purple, red, yellow, striped) and flower colors.
Cannas need rich, moist soil and can even be pond plants (hence the reference to 1"-10" of water). Put lots of organic matter in their soil and fertilize about once a month during their growing season. They are frost tender, so plant after danger of frost, spacing tubers about 18" apart, 4" deep. When frost blackens the foliage in the fall, dig, clean and store the tubers until next spring. I hope this info helps!
