Caladiums are a popular choice for adding vibrant color to gardens and indoor spaces. Properly dividing them before overwintering ensures healthy growth and abundant foliage the following season. This guide provides step-by-step instructions on how to divide caladiums effectively.
Why Divide Caladiums?
Dividing caladiums helps prevent overcrowding, promotes healthy growth, and extends the lifespan of the plants. It also allows gardeners to propagate new plants for sharing or expanding their garden collection.
When to Divide Caladiums
The best time to divide caladiums is in the fall, after the foliage has died back but before the first frost. This timing allows the plant to recover and store energy in its tubers for overwintering.
Tools Needed
- Garden fork or spade
- Sharp knife or garden shears
- Gloves
- Clean bucket or container
- Dusting powder or fungicide (optional)
Steps to Divide Caladiums
Follow these steps to divide caladiums properly:
1. Prepare the Plant
Water the caladium thoroughly a day before dividing to soften the soil and reduce root stress. Wear gloves to protect your skin from sap or irritants.
2. Dig Up the Tubers
Carefully loosen the soil around the plant with a garden fork or spade. Lift the entire clump out of the ground, keeping the root system intact.
3. Clean and Inspect
Gently wash off excess soil from the tubers. Inspect for any damaged, diseased, or rotting sections, and discard those parts.
4. Divide the Tubers
Using a sharp knife or garden shears, cut the tubers into sections, each with at least one eye or growth point. Dust cut surfaces with fungicide or powder to prevent infection.
5. Store or Replant
If overwintering indoors, let the divided tubers dry for a few hours before storing in a cool, dry place. For replanting outdoors, wait until the danger of frost has passed and plant the tubers at the appropriate depth.
Overwintering Tips
Store tubers in a paper bag or mesh container filled with peat moss, sand, or vermiculite. Keep them in a cool, dark, and well-ventilated area. Check periodically for signs of rot or dehydration.
Conclusion
Dividing caladiums before overwintering is an essential step to maintain healthy plants and propagate new ones. With proper timing, tools, and techniques, gardeners can enjoy vibrant caladiums year after year.
