How to Grow Calla Lilies in Zone 6


The calla lily plant is a herbaceous perennial that grows from tuber roots similar to bulbs. The plant is native to Africa and is known for its elegant funnel-shaped flowers. You can plant calla lilies year-round in USDA growing zones 8 through 10. You can grow them in colder zones--including zone 6 where low temperatures range from minus 10 to 0 Fahrenheit--if the tubers are stored indoors during the winter.

Step 1

Select a planting location for your calla lily tubers that has well-draining soil and at least 6 hours of direct sunlight each day.

Step 2

Using a shovel, work 2 to 3 inches of organic compost into the ground at your planting site. Dig a planting hole 4 to 6 inches deep. Place the tubers in the hole so the growing buds face upward. Cover the tubers with soil, making sure the top is sticking out of the ground.

Step 3

Water the soil generously after planting. Continue to water the plants during the growing season when rainfall is less than an inch per week. The lilies prefer a moist soil but will not tolerate standing water.

Step 4

Fertilize the calla lily plants twice a month during the growing season with a liquid general purpose fertilizer. Do not overfeed the plants, as this will result in burnt leaves from too much nitrogen.

Step 5

Apply a 2- to 3-inch layer of mulch around the calla lily plants once they emerge from the ground. This will hold down weeds and help retain soil moisture.

Step 6

Cut calla lily foliage to a length of 2 to 3 inches once the foliage turns yellow in the fall. Remove the calla lily tuber roots from the ground after a strong fall frost. Remove dirt from the tubers and let them dry for two days. Place the tubers in a container filled with peat moss and store them during the winter in a dry location that is at least 60 degrees Fahrenheit.

Step 7

Replant the calla lily tubers in the spring when the danger of frost is over and the soil has warmed past 55 degrees F.
