Answer: Cannas are warm-season flowering plants. It is best to move them when they are dormant during the late winter or the early spring months before new growth begins from the underground rhizomes. Some gardeners like to dig and divide the plantings yearly to prevent crowding and to revitalize the beds.
Do canna lilies grow from rhizomes?
Planting Your Canna Lilies Canna rhizomes can be planted from spring (after all danger of frost has passed) through early summer. If conditions are cool or soil temperature is cold, delay the planting until the soil has warmed to at least 65°F (18°C). Plant your canna rhizomes 4 in. deep (10 cm).
Should I soak canna rhizomes before planting?
Soaking canna bulbs before planting them is not required. However, soaking them for 12-24 hours could help break dormancy faster. Try adding a little fish emulsion or compost tea to the water before soaking them to give them even more of a boost.
Do you have to dig up canna lily bulbs?
“To successfully overwinter cannas indoors, the bulbs should be dug up after the first light frost has killed the top of the plant,” she explains. “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.
How do you split canna rhizomes?
Divide canna lilies in spring before planting them back outside in the garden, or dig them up if you have overwintered them outside (wait for all risk of frost to pass, first). Remove sections of rhizomes with at least two or three growing points, and pot on.
Can you replant canna lily bulbs?
Container grown cannas will need to be replanted in fresh soil next season for best results. Separate the rhizomes with your hands. Be gentle, but do not worry if they break. The fleshy roots will dry up during storage, so again, handle carefully but don’t worry too much about breakage.
How long does it take a canna bulb to sprout?

Do canna lilies multiply?
Canna flowers are not true lilies and their root structures are more like irises than lilies. Like iris plants, canna rhizomes multiply quickly and eventually older rhizomes in the center of the mass can be choked out. Dividing perennial grown cannas every 3-5 years will keep them growing in smaller healthier clumps.
How deep do canna lilies need to be divided?
In warm climates, divided canna lilies are then transplanted 6 inches (15 cm.) deep, and the rhizomes will settle into their new home through winter. In cooler climates, zone 7 or lower, the rhizomes need to be dried out, then stored indoors throughout winter in a location that does not get colder than 45 degrees F. (7 C.).
How do you move a canna lily without killing it?
Of course, knowing how to move a canna lily without causing damage is important too. Carefully dig up the rhizome mass and cut any remaining stems or foliage back to about an inch (2.5 cm.). Brush off any soil stuck to the rhizomes so you can see the joints where new rhizomes grow from older ones.
