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.

We guarantee the perishable items we sell to be in good, viable condition when we sell them. Perishable items include, but are not limited to, garlic bulbs, flower bulbs, seed potatoes, onion sets & transplants, potted or bare root trees, vegetable crowns, etc. If your perishable item arrives in substandard condition, take photographs and please contact us within 3 days of the purchase date (or delivery date) and we will provide you with a refund of the purchase price (excluding shipping costs), or a replacement. Accordingly, we urge you to open any boxes marked as ""Perishable"" immediately upon receiving them and inspect the shipment thoroughly (do not crack open heads of garlic, we do not accept claims on cracked garlic). Because some perishable items can deteriorate very quickly, we cannot accept any claims beyond the 3-day time frame as it becomes too difficult to determine if these items were delivered in substandard condition, or if they turned into such substandard condition because of having been improperly cared for or stored once delivered.
