How to Start Calla Lilies from Seed: A Beginner’s Guide

Calla lilies are elegant and striking flowers that can add a touch of sophistication to any garden or indoor space. Growing calla lilies from seed might seem challenging, but with the right steps, beginners can successfully cultivate these beautiful plants. This guide provides a simple, step-by-step approach to starting calla lilies from seed.

Understanding Calla Lilies

Calla lilies (Zantedeschia spp.) are native to Africa and are known for their distinctive trumpet-shaped flowers. They are perennial plants that thrive in well-drained soil and prefer warm temperatures. While they are often propagated through rhizomes, starting from seed is an alternative method that can be rewarding for gardeners seeking to expand their collection or experiment with propagation techniques.

Gathering Supplies

  • Fresh calla lily seeds
  • Seed-starting trays or small pots
  • Seed-starting soil mix or well-draining potting mix
  • Watering can or spray bottle
  • Plastic wrap or a clear plastic lid
  • Warm, bright location
  • Optional: Rooting hormone

Preparing the Seeds

Calla lily seeds are often small and may require scarification or soaking to improve germination. To prepare the seeds:

  • Gently nick the seed coat with a file or knife to help water absorption.
  • Soak the seeds in warm water for 12-24 hours before planting.
  • If desired, dip the seeds in rooting hormone to encourage root development.

Planting the Seeds

Follow these steps to plant the prepared seeds:

  • Fill your trays or pots with moist seed-starting soil mix.
  • Plant each seed about 1 inch deep, with the pointed end facing down.
  • Lightly cover the seeds with soil and gently water to settle the soil.
  • Cover the tray with plastic wrap or a clear lid to maintain humidity.

Providing Proper Conditions

Calla lily seeds require warm, moist conditions to germinate. Keep the trays in a location with the following conditions:

  • Temperature: 70-75°F (21-24°C)
  • Light: Bright, indirect sunlight
  • Humidity: High humidity to prevent drying out

Check regularly and keep the soil moist but not waterlogged. Remove the plastic cover once sprouts appear to prevent mold growth.

Transplanting Seedlings

When seedlings develop their first true leaves and are strong enough to handle, they can be transplanted into larger pots or outdoors. Follow these tips:

  • Gradually acclimate seedlings to outdoor conditions if transplanting outside.
  • Plant in well-drained soil enriched with organic matter.
  • Space plants about 12-18 inches apart.
  • Water thoroughly after transplanting.

Caring for Calla Lilies

Once established, calla lilies require minimal care to thrive. Ensure they receive adequate sunlight, water regularly, and fertilize during the growing season. Protect outdoor plants from frost by mulching or bringing potted plants indoors during cold weather.

Conclusion

Starting calla lilies from seed can be a rewarding experience that expands your gardening skills. With patience and proper care, you can enjoy the beauty of these elegant flowers in your garden or home. Happy planting!
