When and How to Divide Caladiums for Maximum Impact

by

Caladiums are popular ornamental plants known for their vibrant, colorful foliage. Dividing caladiums is an essential gardening task that helps maintain healthy plants and encourages vigorous growth. Knowing when and how to divide them can maximize their visual impact in your garden.

When to Divide Caladiums

The best time to divide caladiums is during their dormant period, which typically occurs in late fall or early winter after the foliage has died back. Dividing during dormancy minimizes stress on the plant and allows for better recovery. If you live in a region with mild winters, you can also divide caladiums in early spring before new growth begins.

How to Divide Caladiums

Dividing caladiums involves carefully separating the tubers to promote healthy growth. Follow these steps for successful division:

  • Gently dig around the caladium clump to expose the tubers.
  • Use a clean, sharp knife or garden shears to cut the tubers apart. Ensure each piece has at least one eye or growth point.
  • Inspect the divided tubers for any signs of disease or rot. Discard any unhealthy sections.
  • Allow the cut surfaces to dry and callus over for a day or two to prevent rot.
  • Plant the divided tubers in well-draining soil, about 2-3 inches deep, with the eyes facing upward.

Water the newly planted tubers thoroughly and place them in a warm, shaded location until new growth appears. Proper division and planting will ensure your caladiums flourish and display their stunning foliage at its best.

Tips for Successful Caladium Division

  • Use clean tools to prevent disease transmission.
  • Divide only healthy, firm tubers for the best results.
  • Label divided tubers if planting in different locations or varieties.
  • Mulch around the plants to retain moisture and regulate soil temperature.

With proper timing and technique, dividing caladiums can rejuvenate your plants and enhance their visual impact in your garden. Regular division also helps control the size of the clumps, making your garden more manageable and beautiful.
