Plant them in a rich, moisture-retentive soil in full sun or light shade.

What to do with canna bulbs in the fall?
In the fall, dig rhizomes after the leaves have yellowed, died back or have been killed by frost, but before the ground freezes. Leaving your cannas till after a freeze provides the longest possible growing season so the plant can store food for next year’s growth. In cool climates, canna bulbs are planted each spring, then in fall they are dug up, divided and stored away from the winter chill to be replanted in spring. Even in warmer climates, cannas will need to be dug up and divided every 4-5 years.Now it is time to overwinter these tender rhizomes. In the fall, dig rhizomes after the leaves have yellowed, died back or have been killed by frost, but before the ground freezes. Leaving your cannas till after a freeze provides the longest possible growing season so the plant can store food for next year’s growth.During the hottest days, you may need to water every other day.

Cannas are very heat tolerant and thrive in the hottest days of summer, though their flowers can wilt on especially hot days.Although technically they are not bulbs, but rhizomes, cannas need to be treated as tender bulbs and must be dug up to survive the winter.Cannas planted in zones 8 and warmer can be left in the ground all winter. Zone 7 is middle ground for determining what to do with cannas in the winter. Digging cannas in the late fall is necessary to overwinter cannas in zones 6 and colder.
Can a canna lily be a houseplant?
Cannas are very heat tolerant and thrive in the hottest days of summer, though their flowers can wilt on especially hot days. Cannas are sensitive to frost and cold.

Tender perennials, cannas are planted in the garden in late spring to early summer, after the danger of frost has passed. To get a jumpstart on tropical blooms and foliage, many Northern gardeners will start canna rhizomes indoors about four weeks before transplanting them to the garden.Cannas love moisture but don’t like to sit in waterlogged soil. During the growing season, water deeply once or twice a week, depending on rainfall and temperatures. In hot climates, they may need more frequent watering to prevent the soil from drying out.Cannas are slow to sprout. Once sprouted, water at least once a week by slowly soaking the area around the roots. Full foliage color develops when days are warmer (59ºF or more). Blooms should appear in 10 to 12 weeks.Cannas are vibrant tropical plants that can be grown as perennials in USDA hardiness zones 8 to 10. In regions north of zone 8, cannas can’t survive winter in the ground. If you’re in a northern region, you can grow cannas as annuals and discard them at the end of the season, or dig up and store the bulbs for spring.
Do I soak canna bulbs before planting?
Enhancing growth: soaking Canna bulbs Soaking allows the bulbs to absorb moisture, kickstarting their internal processes for robust growth. Begin by placing the bulbs in lukewarm water for a few hours. This hydrates and activates the bulbs, giving them a head start for successful planting.
