When to Harvest Calla Lily Bulbs
The timing of harvesting calla lily bulbs is crucial. It’s best to wait until the foliage has naturally died back, typically in late summer or early fall. This signals that the plant has finished its growth cycle and the bulbs have stored enough energy for the next season. Look for signs like yellowing leaves, wilting stems, and a general decline in plant vigor.
Preparing for the Harvest
Before you start digging, gather your tools and prepare the area. You’ll need:
- A sharp garden trowel or spade: For carefully lifting the bulbs from the ground.
- A bucket or container: To hold the harvested bulbs.
- A dry, airy space: To store the bulbs after they’ve been cleaned.
The Harvesting Process
1. Locate the Bulbs: Gently dig around the base of the plant, carefully avoiding damaging the bulbs. Calla lily bulbs are typically found just below the soil surface.
2. Lift the Bulbs: Once you’ve located the bulbs, use your trowel or spade to gently lift them out of the ground. Be careful not to break the bulbs or damage their roots.
3. Clean the Bulbs: Brush off excess soil and debris from the bulbs. You can also wash them gently with water, but make sure to dry them thoroughly before storing.
Inspecting and Sorting the Bulbs
After harvesting, take a moment to inspect each bulb for any signs of damage or disease. Discard any bulbs that show signs of rot, mold, or insect infestation. You can also sort the bulbs by size, as larger bulbs tend to produce more flowers.
Storing the Bulbs for Winter
Calla lily bulbs require a period of dormancy to prepare for the next growing season. Proper storage is essential for preserving their vitality.
1. Air Drying: Allow the bulbs to air dry in a cool, dry, and well-ventilated area for a few days. This helps to harden the outer skin and prevent rot.
2. Storing in a Cool, Dark Place: Once the bulbs are completely dry, store them in a cool, dark, and dry place. A basement, garage, or even a refrigerator (in a paper bag) can work well.
3. Maintaining Moisture: Avoid storing the bulbs in a humid environment, as this can lead to mold growth. Check the bulbs periodically for signs of rot or damage.
Replanting Calla Lily Bulbs
When spring arrives and the threat of frost has passed, it’s time to replant your calla lily bulbs. Choose a sunny spot with well-drained soil. Plant the bulbs about 4-6 inches deep and 12-18 inches apart. Water them thoroughly to help them establish roots.
Benefits of Harvesting Calla Lily Bulbs
Harvesting calla lily bulbs offers several benefits:
- Propagation: You can use the bulbs to start new plants, expanding your collection or sharing them with others.
- Disease Prevention: Removing the bulbs from the soil helps to prevent the spread of diseases.
- Control: Harvesting allows you to control the number of plants you have in your garden.
- Winter Storage: Storing the bulbs indoors protects them from harsh winter conditions.
