Known for its elegant trumpet-shaped blooms and vibrant foliage, the calla lily perennial (Zantedeschia aethiopica) is a captivating addition to any garden. This versatile plant thrives in a wide range of climates, making it a popular choice among gardeners worldwide.
Cultivation and Care
Planting
Calla lilies prefer well-drained, fertile soil rich in organic matter. They can be planted in full sun to partial shade. Dig a hole twice the width of the root ball and deep enough so that the top of the bulb is slightly below the soil surface. Water thoroughly after planting.
Watering
Calla lilies require regular watering, especially during the growing season. Keep the soil consistently moist but avoid overwatering. Reduce watering when foliage begins to yellow in the fall.
Fertilization
Fertilize calla lilies monthly with a balanced fertilizer during the active growing season. Use a fertilizer specifically formulated for flowering plants.
Pruning
Deadhead spent flowers to encourage new bloom production. Remove yellowing or damaged leaves to improve the plant’s appearance and prevent disease.
Propagation
Calla lilies can be propagated by division. Dig up the plant in the fall or spring and separate the rhizomes. Replant the rhizomes in well-drained soil.
