How to Start Cannas
- 1). Plan ahead for planting canna seeds in your garden. You should start growing canna seeds indoors at least six to eight weeks before the last frost of the spring.
- 2). Use a small nail clipper to nick the edge of the seeds. Soak the seeds in warm water for a day. Plant the seeds in moist, well-drained potting soil in small pots. The seeds should germinate in one to two weeks.
- 3). Grow the cannas in a warm location with plenty of sunlight. Keep the soil well-watered, and fertilize once a month. When the last frost has passed and the weather is consistently warm, transplant the cannas to your garden. You can also keep the plants indoors and transplant them to larger pots as they grow.
