Bleeding heart plants (Dicentra spectabilis) are beautiful perennials that add charm to any garden with their unique heart-shaped flowers. Over time, these plants can become overgrown, leading to crowded roots and reduced flowering. Dividing overgrown bleeding heart plants is an effective way to rejuvenate them and propagate new plants.
When to Divide Bleeding Heart Plants
The best time to divide bleeding heart plants is in early spring or immediately after they finish flowering in late spring to early summer. Dividing during dormancy helps minimize stress and encourages healthy growth. Avoid dividing in the fall, as the plants may not establish before winter.
Tools and Materials Needed
- Garden spade or fork
- Sharp knife or pruning shears
- Gloves
- Watering can or hose
- Mulch (optional)
Steps to Divide Overgrown Bleeding Heart Plants
Follow these steps to successfully divide your bleeding heart:
1. Prepare the Plant
Water the plant thoroughly a day before dividing to soften the soil and reduce stress. This makes digging easier and less damaging to the roots.
2. Dig Around the Plant
Use a garden spade or fork to carefully loosen the soil around the base of the plant. Start digging several inches away from the crown to avoid damaging the roots. Gently lift the entire root ball out of the ground.
3. Divide the Root Clump
Use a sharp knife or pruning shears to cut the root clump into sections. Each section should have at least one healthy crown and a good root system. Be gentle to avoid damaging the delicate roots.
4. Replant the Divisions
Plant each division at the same depth as it was growing before. Space them about 12-18 inches apart to allow for growth. Water thoroughly after planting to settle the soil and help roots establish.
Aftercare Tips
To ensure successful growth of your divided bleeding heart plants, follow these aftercare tips:
- Keep the soil consistently moist but not waterlogged.
- Apply a layer of mulch around the plants to conserve moisture and suppress weeds.
- Fertilize lightly in early spring with a balanced fertilizer.
- Remove dead or damaged foliage to promote healthy growth.
Benefits of Dividing Bleeding Heart Plants
Dividing bleeding heart plants not only helps manage overgrowth but also offers the opportunity to propagate new plants. It can rejuvenate older plants, leading to more vigorous flowering and healthier foliage. Additionally, it allows gardeners to share plants with friends or expand their garden.
