Calla Lily Seed Pod Harvest and Germination: Complete Guide

From Pod to Plant: Growing Zantedeschia from Seed

Allow calla lily seed pods to dry completely on the plant until they turn brownish-yellow. Cut pods and dry indoors for a few more days. Seeds resemble small peas and detach easily from the dried pod.

Sowing and Germination

Start seeds in January: plant ½ inch deep in a seed flat with well-draining soil. Maintain warmth and consistent moisture. Germination takes 2-3 weeks at 75°F. Provide intense light—seedlings need 8 inches of clearance below a 40-watt shop light.

Hardening Off and Transplant

After the last frost, place flats in a shaded, protected area for 10 days (shielded from sun, wind, rain). Then transplant to garden beds. Plants bloom in 2-3 years from seed.

Reviving Pale Pink Blooms

Faded flower color often indicates nutrient deficiency. Apply bone meal or bulb fertilizer per package directions to restore vibrant pigmentation.

Winter Care

In cold climates (like Ohio), lift corms in fall and store in a cool, dry basement until spring replanting.
