Dividing caladiums is a popular way to propagate new plants and refresh older ones. If you plan to delay planting your divided caladiums until later in the season, proper storage is essential to keep them healthy and viable. This guide provides step-by-step instructions on how to store divided caladiums for late planting.
Preparing Caladiums for Storage
Before storing, ensure your caladiums are healthy and free from disease. Carefully dig up the mature caladiums, gently shake off excess soil, and inspect for any damaged or rotting parts. Remove any damaged sections with clean, sharp scissors or pruning shears.
Once cleaned, divide the tubers using a sharp knife or garden shears. Each division should have at least one eye or growth point. Allow the cut surfaces to callus over for a day or two in a warm, dry location to prevent rot during storage.
Cleaning and Curing
After division, it is important to cure the caladiums to prevent rot. Place the tubers in a well-ventilated area out of direct sunlight for 1-2 days. This helps the cut surfaces form a protective callus, reducing the risk of infection during storage.
Storing the Divided Caladiums
Choose a cool, dark, and dry location to store your caladiums. Ideal storage conditions are temperatures between 50-60°F (10-15°C) with low humidity. Avoid exposure to direct sunlight or freezing temperatures, which can damage the tubers.
Pack the caladiums in a breathable material such as paper bags, mesh bags, or peat moss. Do not store them in plastic bags, as this can trap moisture and promote rot. Label each bag with the date of division and variety for easy identification.
Checking and Maintaining During Storage
Periodically inspect the stored caladiums for signs of mold, rot, or dehydration. Remove any tubers showing signs of decay immediately. If necessary, dust the tubers with a fungicide to prevent fungal infections.
Preparing for Late Planting
As the planting season approaches, gradually acclimate the caladiums to warmer temperatures by moving them to a warmer, more humid environment. Before planting, inspect each tuber and replant in well-draining soil, ensuring the eyes are facing upward.
Proper storage extends the life of your caladiums and ensures a healthy, vibrant display in your garden when you plant them later in the season. Follow these steps to keep your divided caladiums in optimal condition for late planting success.
