- Planting the Calla lily in loose soil with good drainage is essential for the flower's health. Temperature changes can stress the bulb, so add mulch to the soil to help maintain a constant temperature around the bulb. This will also absorb moisture.
- The Calla lily is grown from a "tuber," which must be dried out before it can be planted. You can leave the tuber in any well-ventilated area to dry. When choosing where to plant, keep in mind that the lily can grow up to 3-feet tall and take up about one and a half square feet. Once you have chosen a location, plant the tuber approximately 2 inches deep. Stems will develop from the tuber, so ensure they are pointed toward the surface. Calla lilies can grow in direct sunlight or partial shade, depending on the climate. After planting, water the tuber thoroughly. The soil should be kept moist but not soaked.
- When the Calla lilies have withered, you can dig up the tuber, store it in any cool dry location and replant it next spring. You can store the tubers in a bag or container with perlite, peat moss or vermiculite. Once you have replanted them, fertilize them.
