Although not considered true lilies, the calla lily (Zantedeschia sp.) is an exceptional flower. This beautiful plant, which comes in a variety of colors, grows from rhizomes and is ideal for use in beds and borders. You can also grow calla lilies in containers, either outdoors or in a sunny window as a houseplant. Here are a few tips for growing calla lilies that will make them sparkle in your garden. Calla Lilies Growing Tips It’s easy to grow calla lilies. These plants generally don’t require too much attention. Proper planting and location are the only important things to consider when growing calla lilies. Caring for calla lilies requires that they be planted in loose, well-drained soil. They prefer a spot in full sun or partial shade in warmer climates. Calla lilies are usually planted in spring. However, wait until the threat of frost has passed and the soil has warmed sufficiently before planting calla lilies.
Calla lilies should be planted fairly deep, about 4 inches (10 cm) for better results, and spaced about 0.5 m (0.5 m) apart. After planting, the area should be well watered. Calla lilies like to be kept moist and will also benefit from a monthly dose of fertilizer throughout the growing season.
Caring for Calla Lilies As with planting, caring for calla lilies doesn’t require all that much other than watering and fertilizing. An adequate layer of mulch around the plants will help keep the area moist and weed-free. Calla lilies need a dormant period once flowering has stopped. During this time you should water as little as possible so that the plant can die. If you are growing calla lilies in containers, stop watering and place the plant in a dark place once the foliage has faded. Regular watering can be resumed within two to three months.
Although calla lilies can remain in the ground year-round in warmer climates, they should be raised and stored in cooler areas. Caring for calla lilies in winter In autumn, usually after the first frost, dig up the rhizomes and shake off the soil. Let them dry for a few days before storing the rhizomes for the winter. Calla lilies should be stored in peat moss and kept in a cool, dry, preferably dark place until warmer temperatures return in spring. Likewise, you can choose to plant your calla lilies indoors in late winter and transplant them outside in spring. Calla lilies can also be divided when being cultivated or during their dormant period.
