Choosing the Right Location

Calla lilies thrive in well-draining soil and prefer partial shade to full sun exposure. When selecting a planting spot, aim for an area that receives at least six hours of direct sunlight per day. These flowers also appreciate protection from strong winds, which can damage their delicate blooms.

Preparing the Soil

Calla lilies prefer a slightly acidic soil with a pH range of 6.0 to 6.5. Before planting, amend the soil with compost or well-rotted manure to improve drainage and provide essential nutrients. Loose, nutrient-rich soil is crucial for encouraging healthy root growth and supporting the plant’s development.

Planting Depth and Spacing

Plant calla lily rhizomes (underground stems) approximately 4 to 6 inches deep and 12 to 18 inches apart. This spacing allows for proper air circulation and prevents overcrowding, which can lead to disease and poor growth.

Watering and Fertilizing

Watering Needs Calla lilies have moderate water requirements. Water the plants deeply once or twice a week, ensuring the soil remains consistently moist but not waterlogged. Avoid wetting the foliage, as this can promote fungal diseases. During hot, dry periods, increase watering frequency to prevent the soil from drying out completely.

Fertilizing Apply a balanced, water-soluble fertilizer every six to eight weeks during the growing season. Calla lilies are heavy feeders, and proper fertilization is essential for promoting robust growth and abundant blooms.

Maintenance and Care

Deadheading Regularly remove spent blooms by cutting them off at the base of the stem. This process, known as deadheading, encourages the plant to divert its energy toward producing new buds and flowers, extending the blooming period.

Dividing Rhizomes Over time, calla lily rhizomes can become crowded, leading to reduced flowering and overall plant health. Divide and replant the rhizomes every three to four years in early spring or fall for optimal growth and performance.

Winter Care In colder climates, calla lilies may need to be lifted and stored indoors during the winter months. Before the first frost, carefully dig up the rhizomes, shake off any excess soil, and store them in a cool, dry place, such as a basement or garage. In the spring, replant them once the danger of frost has passed.
