Creating a yarrow patch can be a rewarding gardening project, especially if you want to expand your existing yarrow plants or share them with friends. Dividing yarrow is a simple process that helps keep the plants healthy and vigorous. This guide will walk you through the steps to successfully divide and expand your yarrow patch.
Understanding Yarrow and Its Growth
Yarrow (Achillea millefolium) is a hardy perennial known for its feathery leaves and clusters of small, colorful flowers. It thrives in well-drained soil and full sun. Yarrow spreads through both roots and seed, making division an effective way to control its growth and propagate new plants.
When to Divide Yarrow
The best time to divide yarrow is in early spring or late fall, when the plant is not actively flowering. Dividing during these periods minimizes stress and promotes healthy growth. Avoid dividing during extreme heat or cold, as this can damage the plant.
Tools and Materials Needed
- Garden spade or fork
- Sharp knife or pruning shears
- Gloves
- Watering can or hose
- Mulch (optional)
Steps to Divide Your Yarrow
Follow these steps to successfully divide your yarrow:
1. Prepare the Plant
Water the yarrow thoroughly a day before dividing. This helps reduce stress and makes the soil easier to work with.
2. Dig Around the Plant
Use a garden spade or fork to carefully loosen the soil around the yarrow clump. Dig several inches away from the base to avoid damaging the roots.
3. Lift the Clump
Gently lift the entire clump from the ground. Shake off excess soil to expose the roots.
4. Divide the Root Ball
Use a sharp knife or pruning shears to cut the root ball into sections. Each section should have at least one healthy crown and a good amount of roots.
5. 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.
Caring for Your Divided Yarrow
Water the newly planted divisions well and apply mulch around the base to retain moisture and suppress weeds. Keep the soil consistently moist but not waterlogged during the first few weeks.
Additional Tips for Success
- Divide yarrow every 3-4 years to maintain vigor.
- Remove any dead or damaged foliage to promote healthy growth.
- Fertilize sparingly; yarrow prefers lean soil.
- Divide on a cloudy day if possible to reduce stress.
With proper division and care, your yarrow patch will flourish and provide beautiful blooms year after year. Happy gardening!
