I've had great luck with calla lilies in my garden, and I'd be happy to share some tips with you. They prefer bright, indirect sunlight, so a spot near a window or under a tree is perfect. As for watering, make sure the soil is moist but not soggy, as they're prone to rot if it's too wet. After they bloom, you can cut back the flower stalk and let the plant die back naturally, which will help it conserve energy for next year's bloom. In the long term, divide and repot your calla lilies every few years to keep them healthy and thriving.
