Caladiums are vibrant, tropical plants known for their colorful foliage. Properly preparing them for dormancy after the growing season ensures they remain healthy and ready for replanting next year. Deadheading, or removing spent flowers, is an essential step in this process.
Understanding Caladium Dormancy
Caladiums enter dormancy naturally as the weather cools. During this period, the foliage dies back, and the plant conserves energy in its tuber. Preparing for dormancy involves careful steps to protect the tuber and ensure it survives until the next growing season.
Steps to Prepare Caladiums After Deadheading
1. Remove Dead or Dying Foliage
After the flowers fade, cut back the flower stalks and any yellowing leaves. Use clean, sharp scissors or pruning shears to prevent disease.
2. Reduce Watering
Gradually decrease watering as the foliage dies back. The plant no longer needs as much moisture, and overwatering can cause tuber rot.
3. Move the Plant to a Cooler Location
If the plant is in a container, move it indoors or to a sheltered spot with temperatures between 60-70°F (15-21°C). This helps initiate dormancy.
4. Allow the Foliage to Die Back Naturally
Do not cut back the foliage prematurely. Allow it to turn yellow and die back naturally, which indicates the plant is entering dormancy.
Storing Caladium Tubers
Once the foliage has completely died back, carefully dig up the tubers if they are in the ground. Brush off excess soil and let them dry in a cool, dark, and well-ventilated area for a few days.
5. Clean and Inspect Tubers
Remove any remaining soil and inspect for signs of rot or disease. Discard damaged or soft tubers to prevent spread of issues.
6. Store in a Suitable Container
Place the healthy tubers in a paper bag, mesh basket, or cardboard box filled with peat moss, vermiculite, or perlite. Store in a cool, dark place with temperatures around 50-60°F (10-15°C).
Additional Tips for Successful Dormancy
- Label your tubers to avoid confusion during storage.
- Check periodically for signs of mold or rot.
- Replant in spring after the danger of frost has passed.
- Gradually reintroduce water when new growth appears.
Properly preparing caladiums for dormancy ensures they remain healthy and vibrant for many seasons. Follow these steps to enjoy beautiful foliage year after year.
