Growing and Care

Soil and Planting

Light and Temperature

Fertilization

Fertilize Blue Picasso calla lilies monthly during the growing season with a balanced liquid fertilizer. Avoid over-fertilizing, as this can lead to foliage burn. Deadhead spent blooms to encourage continued flowering and prevent seed production.

Winter Care

In USDA hardiness zones 8 and above, Blue Picasso calla lilies can be left in the ground over winter.
