When to Prune Yarrow
The ideal time to prune yarrow depends on your desired outcome.
- Spring (after new growth appears): Pruning in spring encourages bushier growth and a more compact plant.
- Summer (after flowering): Deadheading spent blooms prevents seed formation, promoting continuous flowering and preventing self-seeding.
- Fall (before winter): Cut back stems to the ground to remove old growth and prepare the plant for winter dormancy.
Tools for Pruning Yarrow
For successful pruning, you will need the following tools:
- Sharp, clean pruning shears or scissors
- Gloves (optional)
Step-by-Step Pruning Instructions
Spring Pruning
1. Identify new growth: Locate the fresh, green shoots emerging from the base of the plant.
2. Select stems to remove: Choose weak, spindly, or damaged stems.
3. Cut stems: Cut the selected stems back to the base of the plant, just above the soil line.
Summer Pruning
1. Deadhead spent blooms: Remove wilted flowers by cutting the stem just below the flower head.
2. Prune overgrown stems: Trim back any stems that have become too long or leggy, maintaining a desired height and shape.
Fall Pruning
1. Cut back stems: Cut back all stems to the ground, leaving only a few inches above the soil surface.
2. Remove old foliage: Clear away any dead or yellowed leaves from the base of the plant.
