Steps to Divide Blazing Star
Follow these steps to carefully divide your blazing star:
- Water the plant thoroughly a day before dividing to reduce stress.
- Use a garden spade or fork to dig around the base of the plant, creating a wide circle.
- Gently lift the entire clump from the ground, being careful not to damage the roots.
- Shake off excess soil to expose the root system.
- Use pruning shears or a sharp knife to cut the clump into smaller sections, each with roots and shoots.
- Inspect the divisions and remove any damaged or weak parts.
Transplanting the Divided Blazing Star
Once divided, it’s time to transplant the sections into their new location:
- Choose a sunny spot with well-draining soil.
- Prepare the planting hole by loosening the soil and mixing in compost or organic matter.
- Place each division into the hole, ensuring the crown is level with the soil surface.
- Backfill with soil and gently firm around the roots.
- Water thoroughly to settle the soil and eliminate air pockets.
Caring for Transplanted Blazing Star
Proper care after transplantation ensures healthy growth:
- Keep the soil consistently moist but not waterlogged.
- Apply a layer of mulch around the plant to conserve moisture and suppress weeds.
- Fertilize in early spring with a balanced fertilizer.
- Remove spent flowers to encourage new blooms and maintain appearance.
- Watch for pests and diseases, treating promptly if needed.
Tips for Successful Division and Transplantation
Here are some additional tips to improve your success:
- Handle the roots gently to avoid damage.
- Divide the plant into sections with at least 3-4 shoots each.
- Transplant on a cloudy day or in the late afternoon to reduce stress.
- Ensure the new planting site has good drainage to prevent root rot.
- Be patient; it may take a season for the plant to fully recover and bloom.
With proper timing and care, dividing and transplanting blazing star can rejuvenate your garden and provide stunning displays of purple flowers year after year.
