How To Plant Bulbs Of Calla Lilies?

Calla lilies, known for their elegant tubular shape and vibrant colors, are a beautiful addition to various gardens. They require frost-free conditions, which can be grown on a well-lit windowsill, in a conservatory, or in a heated greenhouse. However, it is best to grow calla lilies from bulbs as sprouting seeds can take a long time.

Calla lilies are native to South Africa and are tropical plants, so they can be kept outdoors in the same conditions. They grow from bulb-like rhizomes, which are flat with noticeable bumps, and require 1 to 1½ feet of growing space between each plant. After planting, thoroughly water the bulbs.

Calla lilies thrive in well-drained, loose soil, and should be planted at a depth of approximately 2 inches with the developing foliage pointing upwards. They need 1 to 1½ feet of growing space between each plant. Planting in the spring after any threat of frost has passed is recommended, but in colder zones, it is advisable to wait until the soil is at least 65°F.

Most Calla Lily varieties are winter hardy in zones 8-10 and should be planted outdoors in the spring after the risk of frost has passed. Plant in the spring months for flowers in June/July. Dig a hole that is approximately 3-4 inches deep and maintain a spacing of about 6 inches between each bulb.

Planting in full to part soil, in soil that drains well, and with adequate moisture are the three most important aspects of growing calla lily bulbs. For your lilies to thrive, they should be planted in loose, well-draining soil in full sun or partial shade in warmer climates.
