Understanding the Calla Lily Life Cycle

The calla lily life cycle begins when soil temperatures warm in late spring. After planting, the Red Alert Calla Lily produces foliage first, followed by bold red blooms in early to midsummer. In USDA zones 8–10, bulbs can remain in the ground year-round. In colder climates, they should be dug up and stored over winter. With proper care and replanting, the bulbs multiply each season, delivering even more showstopping blooms year after year.

Growing Calla Lily Red Alert Bulbs

Plant Red Alert bulbs 4 inches deep and 12 inches apart in loose, well-drained soil. Amend planting areas with compost for added fertility and moisture retention. Place in a site that receives full sun to partial shade and keep soil evenly moist but not soggy throughout the growing period.

Sunlight and Watering

Ensure at least 6 hours of sunlight daily. After planting, water thoroughly and maintain consistent watering during the active growth phase. Reduce watering as foliage yellows and dormancy begins in late summer or early fall.

Care and Maintenance

Deadhead spent blooms to prolong flowering. In cooler regions, dig and store bulbs in a dry, frost-free location. Allow foliage to die back naturally to replenish energy to the bulbs. For detailed bulb care tips, refer to our Flower Bulb Growing Guide.
