Caladiums are popular ornamental plants known for their vibrant, colorful foliage. Harvesting their tubers correctly ensures healthy growth and beautiful plants in the following season. This guide provides step-by-step instructions on how to harvest caladium tubers for future planting.
Timing for Harvesting Caladium Tubers
The best time to harvest caladium tubers is after the growing season has ended, typically in late fall or early winter. Wait until the foliage has turned yellow or brown and has begun to die back naturally. This indicates that the plant has completed its growth cycle and the tubers have matured.
Tools and Supplies Needed
- Garden gloves
- Garden fork or spade
- Pruning shears or scissors
- Clean, dry storage containers or paper bags
- Labels for identification
- Optional: fungicide or fungicidal dust
Steps to Harvest Caladium Tubers
Step 1: Prepare your tools and select a dry, sunny day for harvesting. Wear garden gloves to protect your hands.
Step 2: Carefully dig around the base of the caladium plant using a garden fork or spade. Gently lift the plant, taking care not to damage the tubers.
Step 3: Shake off excess soil from the tubers. If needed, rinse them with water to remove stubborn dirt, then let them dry completely in a well-ventilated area.
Step 4: Inspect the tubers for any signs of rot, disease, or damage. Discard any unhealthy tubers.
Step 5: Cut away any remaining foliage or stems with pruning shears. If tubers are large, you can divide them into smaller sections, each with at least one eye or growth point.
Step 6: Optional: Dust the cut surfaces with fungicide or fungicidal dust to prevent rot during storage.
Storing Caladium Tubers
Store the harvested tubers in a cool, dry, and dark place. Use paper bags or breathable containers to prevent moisture buildup. Label each container with the variety and harvest date. Proper storage can keep tubers viable for several months.
Tips for Successful Replanting
- Inspect tubers periodically for signs of rot or mold.
- Allow tubers to rest for a few weeks before planting again in the spring.
- Plant in well-draining soil with adequate moisture and indirect sunlight.
- Wait until the danger of frost has passed before replanting outdoors.
By following these steps, you can ensure healthy caladium plants year after year, maintaining their vibrant foliage and adding beauty to your garden each season.
