Best Practices for Dividing Caladiums Before the First Frost

Caladiums are beautiful, colorful plants that brighten up any garden during the warm months. To ensure they thrive year after year, dividing them before the first frost is a crucial step. Proper division helps maintain plant health and encourages vigorous growth in the next season.

Understanding When to Divide Caladiums

The best time to divide caladiums is in early fall, just before the first frost. This period allows the plants to recover and establish themselves before winter dormancy. Waiting too long risks frost damage, which can harm the plant’s tubers.

Tools and Materials Needed

  • Sharp garden knife or pruning shears
  • Gloves to protect your hands
  • Large container or bucket for soaking
  • Clean, dry storage containers or paper bags
  • Optional: fungicide for preventing rot

Steps for Dividing Caladiums

Follow these steps to divide your caladiums properly:

1. Prepare the Plants

Gently dig around the caladium clump to loosen the soil. Carefully lift the entire plant out of the ground, keeping the root system intact.

2. Clean and Inspect

Remove excess soil from the tubers and inspect them for any signs of rot or disease. Discard any damaged or soft tubers.

3. Divide the Tubers

Using a sharp knife or shears, cut the tubers into sections, each with at least one eye or growing point. Ensure each division has healthy tissue.

4. Treat and Dry

If desired, dip the cut surfaces in fungicide to prevent rot. Allow the divided tubers to dry in a cool, well-ventilated area for 24-48 hours before storage.

Storing Divided Tubers

Store the dried tubers in a cool, dark, and dry location. Use paper bags or breathable containers to prevent moisture buildup. Check periodically for signs of mold or rot.

Additional Tips for Successful Division

  • Divide only healthy, firm tubers.
  • Label each section if you plan to plant them later.
  • Water the remaining plant lightly after division to reduce stress.
  • Avoid dividing during extremely hot or wet conditions.

By following these best practices, you can ensure your caladiums remain healthy and vibrant for many seasons to come. Proper division before the first frost is a simple yet effective way to maintain a beautiful garden.
