How to Harvest Crocus Corms for Replanting: A Step-by-Step Guide

Harvesting crocus corms is a rewarding process that allows you to propagate these beautiful spring flowers year after year. Properly collecting and replanting corms ensures healthy growth and vibrant blooms. This step-by-step guide will walk you through the process to help you succeed.

When to Harvest Crocus Corms

The ideal time to harvest crocus corms is after the foliage has withered and died back naturally, typically in late spring or early summer. Waiting until the foliage has yellowed ensures the corms have stored enough energy for next year’s growth.

Tools and Preparations

  • Garden gloves
  • Sharp garden trowel or small shovel
  • Clean, dry containers or baskets
  • Disinfectant solution (optional)
  • Storage area with good ventilation

Step-by-Step Harvesting Process

1. Wait for Foliage to Die Back

Allow the crocus plants to complete their natural cycle. The leaves will yellow and wither, indicating that the corms have matured and are ready to be dug up.

2. Carefully Dig Around the Plant

Use a garden trowel or small shovel to gently loosen the soil around the base of the crocus. Be careful not to damage the corms during this process.

3. Lift the Corms Out

Once loosened, carefully lift the corms from the soil. Shake off excess dirt and inspect for healthy, firm corms. Discard any that are soft, moldy, or damaged.

4. Clean and Dry the Corms

Gently brush off remaining soil. Place the corms in a well-ventilated area to dry for several days. Proper drying prevents rot during storage.

Storing the Corms

Store the dried corms in a cool, dry, and dark place. Use breathable containers like paper bags or mesh baskets. Label the corms if you have multiple varieties.

Replanting the Corms

Replant crocus corms in the fall, about 3 inches deep and spaced appropriately. Water them well after planting. With proper care, they will bloom beautifully the following spring.
