How to Grow Cala Lilies in Containers

Calla lily produce flowers in a variety of colors.

Calla lily, or Zantedeshia aethiopica, grows from bulbs, rhizomes or tubers. Calla lilies can mature to a height of up to 2 feet tall. The plants produce stunning trumpet-shaped, fragrant blossoms in various colors, like red, yellow, white, pink and purple. Native to South Africa, the calla lily grows best in USDA hardiness zones 9 to 11 outside. Those living in other areas of the country can grow calla lilies in containers or pots. Use one 6-inch pot to plant each calla lily bulb.

Things You'll Need

• Containers
• Potting soil
• Calla lily tubers/bulbs
• Hand trowel
• Fertilizer

Instructions

1. Fill containers that have drainage holes with good-quality potting soil.

2. Dig a hole to a depth that is twice the size of the calla lily bulb. This may vary depending on the variety selected.

3. Place the side of the calla lily bulb with the most "eyes" facing up, and then cover with soil.

4. Soak the containers with water to moisten the soil thoroughly. Water the calla lilies only when needed to keep the soil moist, but not soggy.

5. Place the containers in locations providing full sunlight.

6. Apply a slow-release fertilizer as directed after the plants emerge and again in the spring each year. Or use a water-soluble fertilizer weekly throughout the growing season.
