Bleeding heart plants ( Dicentra spectabilis) are beloved for their charming heart-shaped flowers. But as these beauties mature, they can become overcrowded, leading to smaller blooms and less vibrant growth. Fortunately, splitting your bleeding heart is a relatively easy way to rejuvenate your plants and even propagate more! This guide will walk you through the process, ensuring your bleeding hearts continue to thrive for years to come.
When to Split Your Bleeding Heart
The best time to split a bleeding heart plant is in early spring, just as new growth begins to emerge. This allows the divided sections ample time to establish themselves before winter arrives. Avoid splitting in the heat of summer, as this can stress the plant and hinder its ability to recover. Late autumn is also not ideal.
Signs Your Bleeding Heart Needs Dividing:
- Reduced Bloom Size and Number: If your bleeding heart's flowers are smaller and less numerous than in previous years, it's likely overcrowded.
- Crowded Growth: Overgrown plants will show dense, matted foliage.
- Poor Drainage: Crowding can impede proper drainage, leading to root rot.
Tools You'll Need:
- Sharp Shovel or Spade: Crucial for cleanly dividing the roots. A dull tool will only crush them.
- Garden Gloves: Protect your hands from dirt and potential scratches.
- Watering Can: To rehydrate your newly planted divisions.
Step-by-Step Guide to Splitting a Bleeding Heart:
-
Prepare the Plant: Water the plant thoroughly a day or two before you plan to divide it. This makes the soil easier to work with and reduces stress on the roots.
-
Dig Up the Plant: Carefully dig around the perimeter of the plant, ensuring you get as much of the root ball as possible. Use a shovel or spade to gently loosen the soil and avoid damaging the roots.
-
Separate the Crowns: Once the plant is out of the ground, gently shake off excess soil to expose the root system. You’ll see individual crowns – essentially, separate growth points with their own roots. Use your hands or a sharp knife (if necessary) to carefully separate these crowns. Aim for sections with at least 3-4 healthy stems and a good root system attached to each division.
-
Prepare New Planting Holes: Dig new planting holes about the same depth and spacing as the original plant. Amend the soil with compost or other organic matter to improve drainage and fertility.
-
Plant the Divisions: Plant the divided sections, ensuring that the crown is at the same level as the soil surface. Gently backfill the holes with soil, firming it around the roots to ensure good contact.
-
Water Thoroughly: After planting, water the newly divided plants deeply to help them settle and begin to grow.
Aftercare for Your Divided Bleeding Hearts:
- Watering: Water regularly, especially during dry periods, until the plants are established.
- Mulching: Apply a layer of mulch around the plants to help retain moisture and suppress weeds.
- Fertilizing: Light fertilization in spring can help promote growth but avoid over-fertilizing.
Propagating More Bleeding Hearts:
Dividing your bleeding heart is not only a rejuvenation process but also an excellent method of propagation. You can now plant the divisions in other areas of your garden, creating a beautiful and bountiful display of these delightful flowers. Give your newly planted divisions plenty of care and attention, and enjoy the fruits (or rather, flowers!) of your labor. By following these simple steps, you can ensure your bleeding heart plants remain healthy, vibrant, and prolific for years to come.
