Caladiums are vibrant, tropical plants that bring a splash of color to gardens and indoor spaces. However, because they originate from warm climates, overwintering them can be challenging for many gardeners. Understanding common mistakes and how to avoid them can ensure your caladiums survive the colder months and thrive year after year.
Common Mistakes in Caladium Overwintering
1. Leaving Caladiums in the Ground During Winter
One of the most frequent errors is attempting to overwinter caladiums outdoors by leaving them in the ground. In regions with cold winters, frost can damage or kill the tubers. Without proper protection, the plant’s survival is at risk.
2. Not Properly Digging Up Tubers
Failing to carefully dig up the tubers before the first frost can lead to damage or loss. Rushing this step or damaging the tubers during excavation reduces their ability to store energy for the next growing season.
3. Incorrect Storage Conditions
Storing tubers in unsuitable environments, such as overly moist or cold areas, can cause rot or desiccation. Proper storage conditions are crucial for successful overwintering.
How to Properly Overwinter Caladiums
1. Dig Up Tubers Carefully
Wait until the foliage has fully died back, typically after a hard frost. Use a garden fork or spade to gently lift the tubers from the soil, taking care not to puncture or damage them.
2. Clean and Dry Tubers
Remove excess soil and allow the tubers to dry in a warm, airy location for a few days. This helps prevent mold and prepares them for storage.
3. Store in a Suitable Environment
- Use a paper bag, mesh container, or cardboard box.
- Keep them in a cool, dark place with temperatures between 50-60°F (10-15°C).
- Avoid areas with high humidity or direct sunlight.
4. Check Periodically
Inspect the tubers every few weeks for signs of rot or mold. Remove any affected tubers immediately to prevent spread to healthy ones.
Additional Tips for Success
Proper watering, timing, and storage are essential for overwintering caladiums successfully. With careful attention to these details, you can enjoy lush, colorful foliage year after year.
