  • Plant in the spring after danger of frost has passed. Start new plants indoors for quicker blooms.

  • 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.
