Growing Calla Lily Picasso Bulbs

Plant these bulbs in spring once the threat of frost has passed. Choose a site with rich, well-drained soil and provide full sun to partial shade. Plant tubers 4 inches deep and 12 inches apart with the growing points facing upward. In USDA zones 8–10, bulbs may be overwintered in the ground. In colder climates, dig and store the bulbs in a cool, dry location for replanting the following spring.

Climate and Soil Requirements

It grows best in USDA zones 8–10. It prefers moist, nutrient-rich, and well-drained soil to support healthy root and bloom development.

Sunlight and Watering

Provide full sun to partial shade. Keep the soil consistently moist, especially during the blooming period, but avoid waterlogging which can cause bulb rot.

Care and Maintenance

Feed monthly during the growing season with a balanced fertilizer. Remove faded blooms to encourage new growth and allow foliage to mature naturally before removing it at the end of the season.
