Calla Lily Planting Guide

How to plant callas:
Plant callas lilies outdoors in a location that gets bright, morning light. They like some late afternoon shade, particularly in hot-summer areas. Keep them well-watered and weeded. Callas grow best in a moist soil that includes some organic matter. Plant the bulbs 4 to 6 inches deep and 1 to 2 feet apart. They can be planted 6 to 12 inches apart when grown in pots. Fertilize monthly with a good all-purpose fertilizer.

When to plant callas:
Although calla lilies are known as 'spring bulbs,' in tropical climates or USDA zones 8-10, calla lilies thrive outdoors year-round. They can be planted at any time!

In other areas, they can be planted when temperatures rest higher than 55 degrees F (below 55 degrees, calla lilies stop growing). Just make sure that there is no danger of frost or of temperatures dropping below 55 degrees in the first 12 weeks after planting.

Did you know...calla lilies make excellent houseplants! They maintain lush green foliage year-round!

During the winter:
In tropical climates (zones 8-10), calla lilies can be left in the ground over winter without trouble, although some gardeners prefer to mulch with bark or straw during the colder months.

In other areas, lift the bulbs before the first frost, clean off excess soil, let dry out of the direct sun for a few days, then store in a dry location that remains between 50 and 60 degrees F. Re-plant in spring after the soil has warmed and all danger of frost has passed.
