Coral bells, also known as Heuchera, are popular perennial plants admired for their vibrant foliage and delicate flowers. Over time, these plants can become crowded, leading to reduced growth and less vibrant foliage. Dividing coral bells is an essential gardening practice that helps maintain plant health and promotes vigorous growth.
Benefits of Dividing Coral Bells
Dividing coral bells offers numerous benefits for both the plant and the gardener. It encourages healthier growth, rejuvenates older plants, and increases the number of plants available for landscaping or sharing. Additionally, dividing prevents overcrowding, which can lead to disease and pest problems.
When to Divide Coral Bells
The best time to divide coral bells is in early spring or early fall. During these periods, the plant is either emerging from dormancy or preparing for winter, which allows it to recover quickly. Avoid dividing during the peak of summer or winter, as extreme temperatures can stress the plant.
Signs That Indicate It’s Time to Divide
- The plant has become overcrowded, with foliage spilling over the container or bed.
- Growth appears sparse or the plant produces fewer flowers.
- The center of the plant looks dead or less vigorous.
- Roots are tightly packed or circling the pot in container-grown plants.
How to Divide Coral Bells
Dividing coral bells involves carefully separating the plant into smaller sections. Follow these steps for successful division:
Tools Needed
- Sharp garden spade or knife
- Gloves
- Pruning shears
- Compost or soil amendments
Step-by-Step Process
1. Water the plant thoroughly a day before dividing to reduce stress.
2. Carefully dig around the plant, loosening the soil with a spade or fork.
3. Gently lift the entire root ball from the ground.
4. Use a sharp knife or pruning shears to divide the root ball into sections, each with roots and foliage.
5. Trim any damaged or dead roots and foliage.
6. Replant each division at the same depth they were growing before, spacing them appropriately.
7. Water the newly planted divisions thoroughly and mulch around them to retain moisture.
Post-Division Care
After dividing, provide adequate water and avoid fertilizing immediately. Keep the soil moist but not waterlogged. Watch for signs of stress or disease, and prune any damaged foliage. With proper care, your coral bells will establish quickly and thrive.
Conclusion
Dividing coral bells is a simple yet effective way to promote healthy growth and expand your garden. By choosing the right time and following proper techniques, you can ensure your plants remain vigorous and beautiful for years to come.
