Best Growing Conditions
The best time to plant canna lilies is in April and May, and are usually best started off in pots. Cannas have strong underground stems, known as rhizomes. In the dormant season you’ll find rhizomes for sale in bags in the garden centre or nursery. In summer they’re sold as potted plants. When planting canna rhizomes into pots, use a large (20cm) plastic pot. Ensure that any shoots are just above the surface. Place the pots in a heated greenhouse, water and wait for signs of life. From late May, after all risk of frost has passes and new shoots or roots have grown, harden off your cannas and and then plant them in the garden. They should flower in their first year. Cannas bought as potted plants can be planted directly into the garden. Water in well and feed with a slow-release fertiliser. They rarely require support.
