Caladiums are vibrant, tropical plants known for their colorful foliage. In cold climates, they require special care to survive the winter months. Proper overwintering ensures you can enjoy their beauty year after year.
Understanding Caladiums and Cold Weather
Caladiums originate from tropical regions and are sensitive to frost. When temperatures drop below 50°F (10°C), their growth slows, and they risk damage or death if exposed to freezing conditions. Therefore, overwintering is essential in colder zones.
Preparing Caladiums for Overwintering
Before the first frost, it’s important to prepare your caladiums for the off-season. This involves carefully digging up the tubers and cleaning them for storage.
Digging Up the Tubers
Use a garden fork or shovel to gently lift the caladiums. Be careful not to damage the tubers. Shake off excess soil and inspect for any signs of disease or rot.
Cleaning and Curing
Rinse the tubers with water and allow them to dry in a warm, dry place for a few days. This curing process helps prevent rot during storage.
Storing Caladium Tubers
Proper storage conditions are vital for overwintering success. Keep the tubers in a cool, dark, and well-ventilated space.
Ideal Storage Conditions
- Temperature: 45-55°F (7-13°C)
- Humidity: Moderate, around 50%
- Light: Darkness or minimal light
Place the tubers in paper bags, mesh baskets, or cardboard boxes filled with peat moss, vermiculite, or sawdust to prevent drying out.
Replanting in Spring
As the weather warms and the danger of frost passes, it’s time to replant your caladiums outdoors or in containers. Choose a location with partial shade and well-draining soil.
Replanting Tips
- Plant tubers 2-4 inches deep
- Space tubers 12-15 inches apart
- Water thoroughly after planting
With proper care, your caladiums will thrive and display their stunning foliage once again each growing season.
