- Plant in the spring after danger of frost has passed. Start new plants indoors for quicker blooms.
- Space low-growing varieties 10 to 12 inches apart and taller ones up to 24 inches apart. Plant 4 to six inches deep.
- Fertilize only when the plants are actively growing, and keep the withered blooms picked off.
- Cannas are native to tropical and subtropical areas and can't tolerate freezing temperatures. In zones colder than 7 they should be lifted and stored in a frost free area for the winter.
- If overwintered in the ground, lift and divide every three to four years. Leave 3 to 4 eyes on each division for strong, sturdy plants.
A tub of cannas makes a terrific accent for a sunny patio or porch.
