Often asked: How Do You Repot Canna Lilies?

How to Replant Canna Lily Rhizomes

  1. Dig up the canna plant for transplanting, if applicable, in fall before hard frost or in spring before new growth begins.
  2. Turn a 2-inch compost layer into the top 6 inches of soil with a spade.
  3. Plant the canna root so the top sits 2 inches beneath the soil surface.

When can you repot cannas?

A plant should be repotted when its root system has grown to take up all of the soil it is growing in. Water immediately if plants are under lighting, or in a hot or dry environment. Watering can wait up to half an hour if the climate is cooler and the lighting is less intense.

What time of year do you transplant canna lilies?

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.

When should you divide canna lilies?

The best time to dig up your canna lilies is when they aren’t blooming. If you store your bulbs in the winter, then divide when you dig them up for storage. If you leave your bulbs in the ground all year round, dig them up in the fall or early spring every three or four years.

How often should I water cannas?

Once sprouted, water cannas at least once a week by slowly soaking the area around the roots. During the hottest weeks of the summer, give the plants a good soaking drink of water every other day.

Are cannas sun or shade?

Cannas thrive in hot, humid weather. They are thirsty plants and need a consistent supply of water throughout the growing season. In warm areas, cannas grow well in full sun or in partial shade. In cooler areas they grow best in full sun.

How do you keep cannas blooming?

For best blooms, plant cannas in full sun, water regularly and fertilize plants 2-3 times throughout the growing season with a general 10-10-10 fertilizer. The most common reason for no flowers on a canna plant is overcrowding. When grown as perennials, canna lilies will grow and spread very quickly.

What kind of soil do cannas like?

Canna lily plants prefer rich, water-retentive, well-drained soils that are high in organic matter but will do fine in a wide range of soils. They prefer a pH around 6.5.

How do you plant calla lilies in pots?

Plant the calla lily rhizomes about 2 inches deep in a well-drained potting mix with the eyes (or in my case shoots) facing up. After potting, water well and place the containers in a warm spot. Keep the potting mix moist, but not wet (or you will rot the bulbs).

Do canna lilies need full sun?

Cannas are moisture-loving bulbs that thrive in wet soil and full sun. These plants grow to be large, so make sure they have space to spread out.

Can I transplant cannas in spring?

The Canna bulbs, which are actually swollen root sections called rhizomes, require division every four years to prevent overcrowding. Transplant Canna in warm climates during spring just as its new growth begins. In colder regions, dig up Canna in autumn before the first expected frost.

What is the difference between a canna lily and a calla lily?

Cannas grow anywhere between 1 1/2 and 8 feet tall with a spread of up to 6 feet, whereas callas are generally more restrained, growing to only 2 or 3 feet with a 2-foot spread. Canna and calla leaves bear some resemblance to one another in that they are both long and wide, tapering at one end.

Can canna lilies be transplanted?

Not only can you transplant and divide canna lilies, but you actually should do so every few years to prevent overcrowding, disease and pests. Like iris plants, canna rhizomes multiply quickly and eventually older rhizomes in the center of the mass can be choked out.
