Caladiums are vibrant, colorful plants that bring a tropical touch to gardens and indoor spaces. However, they are sensitive to cold temperatures and require proper care to survive winter. This guide provides step-by-step instructions on how to prepare your caladiums for the colder months, ensuring they return healthy and beautiful next season.
Understanding Caladiums and Their Winter Needs
Caladiums are native to tropical regions of South America. They thrive in warm, humid environments and are not frost-tolerant. As temperatures drop below 60°F (15°C), their foliage begins to decline, signaling that it’s time to prepare for winter. Properly overwintering caladiums can extend their life and preserve their striking foliage for years to come.
When to Start Preparing Your Caladiums
The ideal time to start preparing caladiums for winter is when nighttime temperatures consistently fall below 60°F (15°C). In most regions, this occurs in late fall. Monitor local weather forecasts and be proactive to ensure your plants are protected before the first frost.
Signs That It’s Time to Dig Up Your Caladiums
- Foliage turning yellow or brown
- Leaves wilting or dying back
- First frost forecasted within a week
Steps to Prepare Caladiums for Winter
Follow these steps to safely store your caladium tubers during winter:
1. Cutting Back the Foliage
Once the foliage has yellowed and died back naturally, cut the stems close to the tuber. Use clean, sharp scissors or pruning shears to prevent disease.
2. Digging Up the Tubers
Carefully dig around the plant with a garden fork or shovel, avoiding damage to the tubers. Lift them out gently and brush off excess soil.
3. Cleaning and Inspecting
Rinse the tubers with water to remove remaining soil. Inspect for any signs of rot or disease. Discard any damaged or soft tubers.
4. Curing the Tubers
Allow the tubers to dry in a warm, well-ventilated area for a few days. This helps to prevent mold and prepares them for storage.
5. Storing the Tubers
Store the dried tubers in a cool, dark, and dry place. Use paper bags, mesh containers, or peat moss to keep them from rotting. Maintain a temperature of about 50-60°F (10-15°C).
Additional Tips for Successful Overwintering
Here are some extra tips to ensure your caladiums survive winter and thrive next season:
- Label your tubers to remember their varieties.
- Check stored tubers periodically for signs of rot or drying out.
- Replant tubers in spring after the danger of frost has passed.
- Start with healthy, pest-free tubers for best results.
Conclusion
Preparing caladiums for winter is a simple process that can save you money and preserve your favorite plants. With proper timing and care, your caladiums will return vibrant and lush each year, brightening your garden or indoor space for many seasons to come.
