Calla lily is also called arum-lily, which has large, exotic-looking spathes that look like flowers, and is now widely available in a variety of colours. These flowers are always beautiful in gardens and patios, so planting calla lilies is almost a must-do.
When Does Calla Lily Bloom?
Calla lilies bloom from early summer to late fall on strong upright stems, its beautiful foliage adds to the ornamental value of calla lilies. The lush, bright green leaves are often dotted with silver or white and Care wide and broad. Calla lilies can be kept in the freezer for up to two years. The rhizomes and fleshy roots of most calla lily can then be replanted in the spring. White arum lily (Zantedeschia alpina) is the exception. It is not hardy in warm areas.
How To Grow Calla Lilies
Calla lilies can be purchased as rhizomes, or pot-grown plants. They are best grown in pots made of peat-free multipurpose compost and placed in an area that is frost-free. Make sure to water and feed them regularly. Then bring them indoors in autumn for overwintering.
Where to Grow Calla Lilies
Calla lily hybrids need to be kept warm as they can easily withstand frost damage. You can grow them in a sunny window, conservatory or heated greenhouse. Calla lily is safe to grow in the garden or in pots once the frost is gone. The ideal is a bright, well-lit area that receives the strongest midday sunlight. Plants can tolerate some shade but should be avoided in total shade. It’s important to protect them from the wind.
How To Plant Calla Lily
Calla lilies grow from thick rhizomes and fleshy roots. These are usually sold in spring or winter when they are dormant. You can buy ready-grown plants in spring or summer, usually when they are in full bloom.
Dormant Rhizomes can be grown by being purchased in spring or winter and planted 8-10 cm deep in a multi-purpose, peat-free potting soil. For earlier blooms, you can either pot up and begin indoor growth or transplant outside after the frosts. Indoor plants must be hardened off to make them adjust to outdoor conditions by being exposed for longer periods of time.
Calla lilies can be grown in the ground. To improve soil, add plenty of compost or a soil conditioner. Plants should be spaced 30-45 cm apart.
Taking Care of Calla Lilies
To maintain calla lily’s lush, handsome growth, it is essential to water them regularly. It is best to keep the compost moist, but not over-water. After the calla lily flowers, you should feed it every three to four weeks with liquid fertilizer rich in potash. Don’t forget to remove all dead or faded flower stems and leaves regularly.
How To Care For Lillies After Flowering
After flowering is finished, you can continue to water and feed calla lilies for several more weeks. However, it is important to not over-water the plants until they start to lose their leaves. Potted plants should be brought indoors prior to the frosts. Leave the pot in its place while it is dormant. Calla lily that have grown in the ground should be pulled up and the rhizomes placed in trays of moist compost in a cool, frost-free area. Repot the roots in moist compost, and place them in a warm area to begin growth.
Propagating Calla Lilies
Calla lily rhizomes are advised to be divided in late winter before replanting them.
