Is It Possible To Split Calla Lilies In Autumn?

Calla Lilies grow from rhizomes, which spread and sprout from underground. They are best divided in spring or fall, especially in warm climates where the rhizome can be left in the ground year-round. To ensure the health of your Calla Lilies, divide them during their dormant period, typically in late fall or early winter.

When replanting the divided bulbs, ensure they are planted at the correct depth. Calla lily rhizomes can be lifted in fall after the foliage turns brown and pulls away from the roots easily. Remove any remaining foliage and brush off the soil, then cut or break apart the rhizome, making sure each section has at least one eye.

Dividing calla lilies during the winter months whenever necessary is recommended, as there is no set timetable. The clumps are dug up and segmented into smaller sections. Divide calla lily rhizomes in late winter or early spring to allow new divisions time to establish before the summer growing season.

Dividing calla lilies depends on where you live, with experts suggesting late September as the best time for division. In warmer climates, it is best to divide calla lilies in the spring after frost has passed and the soil is beginning to warm. In cooler areas, dividing calla lily bulbs in late September is recommended.

In summary, dividing calla lilies is a simple process that can help propagate and rejuvenate plants.

How do you divide lilies in the fall?

Early fall is a good time to dig and divide Asiatic, Oriental, and other garden lilies. Carefully dig up the clump, separate the bulbs, and replant them immediately. If planting is delayed, place the bulbs in a plastic bag containing lightly moistened sphagnum peat moss and place in the refrigerator. Plant the bulbs as soon as possible. Tiger lilies are not suitable for planting near Asiatic, Oriental, or other garden lilies due to the risk of lily mosaic virus.

This virus causes little harm to tiger lilies but can be carried by aphids and other sap-feeding insects. Infected hybrid lilies produce distorted foliage and fewer flowers, so they should be dug up and discarded.

Can I divide calla lilies in the fall?

Divide calla lilies in spring, especially in warm climates where the rhizome can be left in the ground year-round. In cooler areas, divide them in late summer or fall when they are dignified for winter storage. To divide calla lilies, lift them in fall after the foliage turns brown and pulls away from the roots easily. Remove any remaining foliage and brush off the soil. Cut or break apart the rhizome, ensuring each section has at least one eye. Let the rhizomes dry for a day to form a callus before replanting.

If you live in cooler areas, store the rhizomes and replant them in the spring. Allow them to dry in a well-ventilated area for two to three days, brush off any dirt, and dust the bulbs with bulb dust to prevent rot. Store them in a paper bag of peat moss or vermiculite in a cool, dry location. In late winter or spring, chop apart sections of the plant at the first sign of new growth, lift them, and replant them immediately. This method is easier for new gardeners as it doesn’t require identifying the eyes.

What to do with calla lilies in the fall?

Calla lilies are tender perennials that require their rhizomes to be dug up in fall and stored indoors during the winter months. After a killing frost, cut off the foliage 1 to 2 inches above the soil surface. Carefully dig up the rhizomes, avoiding cutting or injuring them. Dry them in a warm, dry location for 1 to 2 weeks, then bury them in vermiculite, sawdust, or peat moss. Store them in a cool, dry location between 50 to 60 degrees Fahrenheit. For more information on overwintering tender perennials, refer to the article on how to do so.

Is it too late to divide lilies?

Lilies require division and transplanting in late September or early October for optimal results. They should be lifted and transplanted immediately after being lifted. The best time to transplant depends on the zone, and some plants may last longer into the season. Allowing them to remain with foliage intact until the last possible date before frost helps them gather energy for massive blooms. Division of lilies should be included in your list of fall chores a few weeks before the first frost date. Sign up for the Gardening Know How newsletter to receive a free download of our DIY eBook.

Can calla lilies be left in the ground over winter?

Calla lilies are not cold hardy, so their winter care in warm climates is different from other gardens. If you live in USDA plant hardiness zone 8 or higher, your calla lilies can survive the winter outdoors in the ground without needing to be dug up. To do this, mulch the spot where they grow and stop watering for the winter, allowing the plant to go dormant and rejuvenate itself. If you find your calla lilies are not performing well in a warmer climate, store the calla lily rhizome for winter.

In colder climates, calla lilies will not survive the winter cold, so winter care will involve digging the rhizome of the plants. Digging them after frost has killed the foliage ensures that the calla lilies have stored all the nutrients they need to survive the winter. After digging, brush off any remaining dirt, leave the rhizomes to dry in a warm, dry place for four to seven days, or curing them. Store the calla lily rhizomes in a cool, dry place around 50 F.

(10 C.) and ensure proper winter care for these lovely flowers to keep them in your garden year after year. Sign up for the Gardening Know How newsletter today to receive a free download of our DIY eBook “Bring Your Garden Indoors: 13 DIY Projects For Fall And Winter”.

Do calla lilies get cut back in the fall?

Calla lilies should not be pruned regularly, except for withered flowerheads and leaves that turn yellow prematurely. They should be repotted every 2 to 3 years, using a flower pot at least one third larger in diameter than the root ball. The pot should have a water drainage hole and a drainage layer like coarse gravel at the bottom. A potting soil like Plantura Organic Flower Compost, mixed with up to 30 pine bark, is suitable for calla lilies, as it requires a coarse, organic substrate.

The peat-free organic potting soil contains quality compost, coconut and wood fibers, crushed expanded clay, clay minerals, lime and magnesium fertilisers, and a primarily organic fertiliser. This soil provides all essentials for long-term plant growth and beautiful blossoms.

Should calla lilies be dug up for winter?

Overwintering indoor and garden calla lilies differs significantly. Indoor callas can be overwarmed as a whole plant, but they require a bright location without direct sunlight and a constant temperature of 10°C or less. Garden callas require preparation starting in August, stopping fertilization and gradually decreasing watering. In early October, the tubers are extracted and cut back to five centimetres. The soil is carefully removed, and the tubers are dried on a rack for two to three days.

The callas are then moved into their winter quarters, such as a dark, dry place like a cellar. Temperatures should never rise above 15°C or below 0°C, as they will freeze. The tubers are placed in a box filled with dry sand or dry straw, allowing them to rest over winter and be planted out again in the spring. This method ensures the calla lily’s survival during the winter without damage.

What happens if you don’t divide lilies?

Lilies, beautiful perennial flowers, can become overcrowded when their bulb structure becomes too large. To prevent this, divide them every 3-4 years, and after 3-4 years, they can be planted again. Once the bulbs are separated, they can be planted back in the ground or in a container. It’s important to water the bulbs immediately to ensure they grow well next year. After 3-4 years, wait until the stems and leaves turn from yellow to brown before digging up the bulbs to avoid harming the plants. Transplanting in early spring may not yield as many flowers or blooms. Avoid digging up bulbs on warm, sunny days to avoid damaging them.

Do calla lilies multiply every year?

Calla lilies are perennial plants that can produce new growth and blooms year after year under the right conditions. They require well-drained soil, regular watering, and partial shade to full sun. They are hardy in USDA zones 8-10, but may need indoor storage in colder climates to prevent frost damage. Calla lily flowers contain calcium oxalate crystals that can cause irritation and swelling in the mouth, tongue, and throat.

Ingestion can lead to difficulty breathing, kidney failure, and even death in cats. The description of these plants is based on various external sources and height, bloom time, and color may vary in different climates.

Can you transplant calla lilies in the fall?

The optimal period for transplanting calla lilies is mid-spring to early summer or late fall to mid-winter. This ensures optimal growth, with a well-drained location and gentle root care to reduce shock during transplanting.

Do calla lilies multiply?

Calla lilies reproduce vegetatively via the formation of growth buds on their rhizome, a process that can be readily managed in a majority of climatic conditions.
