When Should Calla Lilies Be Divided?

Calla lilies are a popular plant for their dormant period, typically in late winter or early spring. They can be divided during this time, especially in warm climates where they can remain in the ground year-round. In cooler areas, they can be divided in late summer or fall when the plants have finished. The best time to divide calla lilies is in late winter or early spring after all frost danger has passed, or in late summer or fall when the plants have finished.

To propagate calla lilies, divide the rhizome in late winter before replanting. In zones 8-11, dividing and transplanting can be done when the plants have finished blooming and the foliage begins to die back. The best time to dig up canna lilies is when they aren’t blooming, either by storing them in winter or digging them up just before new growth begins.

The Royal Horticultural Society suggests dividing in spring if needed. Divide the rhizomes of your calla lily when you first notice tiny green new shoots begin to form. The best time to divide calla lily bulbs is during their dormant period, typically in late winter or early spring. Calla lilies can be divided during the winter months whenever necessary, with no set timetable. The clumps are dug up and segmented into smaller pieces.

Do calla lilies like sun or shade?

Calla Lilies, native to South Africa, are tender perennial plants that grow from a bulb-like rhizome. They thrive in full sun or partial shade, with full sun being ideal for cool summer areas and partial shade for hot summers. They thrive in organically rich, moist, well-drained soils, with consistent moisture but avoiding overwatering to prevent rot. These flowers, known as chalice-shaped flowers, surround a yellow finger-like stalk. They are easy to grow, providing a spectacular effect with their rich, cheerful colors and chalice-shaped flowers.

They bloom from 6 to 12 weeks in late spring and throughout the summer, depending on location and variety. There are early-season, mid-season, and late-season calla lily varieties available. However, they are poisonous and can cause severe discomfort if ingested. To ensure the best results, choose rhizomes that are large, firm, and plump, as the size of the rhizome is highly correlated to the plant’s overall size and its blossoms.

How do you keep calla lilies blooming all summer?

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.

Do calla lilies grow better in pots or in the ground?

Calla lilies are suitable for houseplants, patios, or seasonal outdoor bedding displays. They should be planted under the soil surface with the rhizome’s eyes facing upwards. A loam-based compost like John Innes No. 2 or a good multi-purpose compost is suitable for pot planting. Plant one rhizome to an 8″ pot or three to a 16″ pot. Cover the pots with decorative stones if desired. Water freely during the summer months and feed with a fertilizer every two weeks.

Caring for calla lilies involves lifting them before frosts and storing them in trays of compost in a cool, dark, frost-free location. Do not overwater and ensure that the rhizomes are covered with decorative stones if desired. In most areas, the foliage will be affected by frost and slightly blackened.

How do you know when to repot a Calla Lily?

Calla Lilys may need repotting if they experience root-bound symptoms, such as root congestion, stunted growth, reduced flowering, or water drainage issues. Root congestion indicates the plant is pleading for a new home, while stunted growth and reduced flowering indicate a sense of squeeze. Water drainage problems, where water rushes through the pot without allowing roots to drink, or pools at the top, are also signs of root-boundness. It’s crucial to address these issues to ensure the plant’s health and longevity.

Do calla lilies like big pots?

Calla lily rhizomes thrive when planted 1 inch deep and 1 to 2 inches apart in pots at least 10 to 12 inches in diameter. Proper drainage is crucial to prevent rots and fungal diseases. The planting medium should retain moisture without being too soggy. Calla plants should be watered when the first inch or two of the soil is dry to the touch, then deeply and thoroughly. Overwatering can cause brown foliage tips. Container-grown calla lilies should be fed a general-purpose fertilizer every three to four weeks in spring and summer.

They grow best in full sun to part shade, with ideal temperatures between 60 and 75 degrees F. and nighttime temperatures not below 55 degrees F. If potted calla lilies are grown indoors, these ideal temperatures should be maintained.

How many years do calla lilies last?

Calla lilies are perennial flowers that live for at least two years and thrive in ponds, streams, or rivers. They can thrive all year through multiple growing seasons with the right temperature and climate. Perennial plants bloom during spring and summer, die back in autumn and winter, and return in the following spring. The rootstock, which sits underground, is responsible for a plant’s ability to survive winter without dying completely, protecting it from harsh weather conditions.

Can I transplant lilies in summer?

If your lily garden is at risk due to new patio or city road/water/power line work, you can safely relocate them by digging up the entire clump with a good root ball of soil. Fill a hole slightly larger than the required size with water and loose soil to create “mud”. Place the entire clump into the hole, filling in and gently tamping loose soil around the root ball. Use just enough water to firm the soil and withhold water until the soil has started to dry out, typically 7 to 10 days.

This method should only be tried under emergency conditions, as the best time to transplant is in the fall after foliage has matured. Avoid giving the bulbs extra water to cover “transplant shock” and stop watering until the soil is dry at least two inches below the surface.

What happens if you don’t divide lilies?

Lilies, regardless of their Asian or Oriental origin, add beauty and serenity to any landscape. They undergo naturalization, where the plant produces more bulbs that mature under the soil. As the bulbs grow older, they become the center of the action and require lifting and transplanting to create new stands of vigorous blooms. Most zones allow for lifting and separating bulbs, and planting them to overwinter in the ground. However, colder climes may require indoor storage and chilling before planting outdoors in spring. Only in colder regions should bulbs be stored indoors.

What time of year do you split lilies?

Lilies, which produce from bulbs, require division and transplanting in the fall for optimal results. Experts recommend late September or early October for this process. Once lifted, transplant the bulbs immediately. The best time to transplant depends on the zone and the plant’s longevity. Some plants may last longer and should be left with foliage intact until the last frost date to gather energy for massive blooms.

Division of lilies should be done a few weeks before the first frost, and every 2 to 3 years for optimal lily stands. If uncertain, dig up the lilies when the foliage starts to yellow and separate and replant them.

How do you split and replant calla lilies?

It is possible to divide large overwintered garden clumps into smaller sections by lifting the plant before top growth, cutting through the roots with a spade, and subsequently dividing the roots into smaller sections.

What month do you divide calla lilies?

The optimal period for new growth is in late winter or early spring, immediately preceding the onset of new growth.
