Caladiums are beautiful, colorful plants that thrive in warm weather. However, to enjoy their vibrant foliage year after year, proper winter storage is essential. Deadheading, or removing spent flowers, helps the plant focus energy on bulb development, which is crucial for winter care. Here’s a comprehensive guide on how to store caladiums after deadheading for the winter months.
Preparing Caladiums for Storage
Before storing your caladiums, it is important to prepare them properly. This involves waiting until the foliage has naturally died back, which indicates the plant has finished its growing cycle for the season. Carefully remove any remaining dead or yellowing leaves to prevent disease.
Digging Up the Bulbs
Once the foliage has completely died back, gently dig around the plant with a garden fork or trowel. Be careful not to damage the bulbs during this process. Lift the bulbs out of the soil and brush off excess dirt.
Cleaning and Curing
After removing the bulbs from the ground, rinse them with water to eliminate any remaining soil. Allow the bulbs to dry in a warm, well-ventilated area for about one to two weeks. This curing process helps prevent rot and prepares the bulbs for storage.
Storing Caladium Bulbs
Store the cured bulbs in a cool, dry, and dark location. Ideal storage conditions are temperatures between 50-60°F (10-15°C). Place the bulbs in paper bags, mesh bags, or cardboard boxes with some sawdust, peat moss, or vermiculite to absorb moisture and prevent mold.
Additional Tips for Successful Storage
- Inspect bulbs periodically for signs of rot or mold.
- Keep the storage area well-ventilated to prevent excess humidity.
- Label the bulbs with the variety name for easy identification next season.
Replanting in Spring
When the danger of frost has passed, you can replant your caladium bulbs outdoors or in containers. Choose a sunny location with well-draining soil. Plant the bulbs about 2-4 inches deep and water thoroughly. With proper care, your caladiums will flourish again, showcasing their stunning foliage.
