3. Planting Your Canna Lilies. Canna rhizomes can be planted from spring (after all danger of frost has passed) through early summer. They may be started indoors as early as a month before the average last frost date (for earlier blooms) or planted directly in the ground after the danger of frost has passed.

Beside this, when should canna bulbs be planted?

When to Plant Cannas

  1. Plant outdoors in late spring and early summer. Soil temperature must be 60°F (15°C) or warmer.

Keep plants well watered and weeded.
