When to plant red canna lily bulbs?
Cannas are heat-loving plants and will not grow in cold soil. The rhizomes can be planted as soon as all danger of frost has passed, but it’s best to wait until the soil has warmed to at least 65°F. In northern areas this will be late May to early June. Cannas thrive in hot, humid weather. In colder areas north of zone 8, these tropical beauties won’t survive in the ground during winter.
