Caladiums are popular ornamental plants known for their vibrant, colorful foliage. Over time, these plants can become crowded, leading to less vigorous growth and smaller leaves. Dividing and replanting caladiums is an effective way to rejuvenate your plants and achieve a lush, thriving display.
Understanding Caladium Growth
Caladiums grow from underground tubers, which store energy and nutrients. Each tuber produces several stems and leaves during the growing season. As the plant matures, the tubers can multiply and become crowded, reducing airflow and access to nutrients. Proper division and replanting help maintain healthy growth and vibrant foliage.
When to Divide Caladiums
The best time to divide caladiums is in early spring before new growth begins or in late fall after the foliage has died back. Dividing during dormancy minimizes stress on the plant and allows for better establishment in the new location.
Signs Your Caladium Needs Dividing
- Stunted or smaller leaves
- Reduced vigor and fewer new shoots
- Overcrowded tubers in the soil
- Fungal or pest issues due to poor airflow
Steps to Divide and Replant Caladiums
Follow these steps to successfully divide and replant your caladiums:
1. Prepare Your Tools and Workspace
Gather a sharp garden knife or pruners, gloves, and a clean workspace. Prepare a container with water or a mild fungicide solution to prevent disease spread.
2. Remove the Tubers
Carefully dig around the caladium clump to expose the tubers. Gently lift the entire root ball and shake off excess soil.
3. Divide the Tubers
Inspect the tubers for natural divisions or eyes—small indentations or growth points. Use a sterilized knife to cut large tubers into sections, each with at least one eye or growth point. Discard any rotted or diseased tubers.
4. Cure the Divided Tubers
Allow the cut surfaces to dry and callus over for 24-48 hours in a warm, shaded area. This helps prevent rot during replanting.
5. Replant the Tubers
Plant each tuber in well-draining soil, about 2-3 inches deep, with the eye facing upward. Space tubers 8-12 inches apart in a prepared bed or container.
6. Water and Care
Water thoroughly after planting. Keep the soil consistently moist but not waterlogged. Place the plants in a warm, shaded location until new growth appears, then gradually introduce them to full sun.
Additional Tips for Lush Caladiums
To maintain healthy, vibrant caladiums:
- Provide partial shade in hot climates to prevent leaf scorch.
- Use a balanced fertilizer during the growing season.
- Keep soil consistently moist but avoid overwatering.
- Mulch around the plants to retain moisture and regulate soil temperature.
Dividing and replanting caladiums not only rejuvenates your plants but also allows you to propagate new ones for sharing or expanding your garden. With proper care, your caladiums will reward you with lush, colorful foliage season after season.
