Yarrow ( Achillea millefolium) is a hardy, drought-tolerant perennial prized for its feathery foliage and clusters of small, daisy-like flowers. Whether you're dividing overcrowded clumps or moving yarrow to a more suitable location, transplanting this resilient plant is relatively straightforward. This guide will walk you through the process, ensuring your yarrow thrives in its new home.

When to Transplant Yarrow

The best time to transplant yarrow is in early spring or fall. Spring transplanting allows the plant to establish itself before the heat of summer. Fall transplanting gives the yarrow time to root before winter dormancy. Avoid transplanting during the hottest part of the summer, as this can stress the plant and reduce its chances of survival.

Choosing the Right Location for Your Yarrow Transplant

Yarrow prefers full sun (at least 6 hours of direct sunlight daily) and well-drained soil. While it tolerates a range of soil types, it thrives in slightly alkaline conditions. Before transplanting, consider the following:

Sunlight: Ensure the new location receives ample sunlight.
Soil Drainage: Poor drainage can lead to root rot. Amend heavy clay soils with organic matter to improve drainage.
Space: Give your yarrow enough room to grow. Clumps can spread significantly over time.

Tools and Materials You'll Need

Before you begin, gather these essential tools:

Gardening Gloves: Protect your hands from thorns and soil.
Sharp Shovel or Trowel: For digging up and planting the yarrow.
Watering Can: To water the transplanted yarrow thoroughly.
Garden Fork (optional): Helpful for loosening compacted soil.
Organic Compost or Soil Amendment (optional): To improve soil quality.

How to Transplant Yarrow: A Step-by-Step Guide

Step 1: Prepare the New Planting Site

Dig a hole twice as wide and as deep as the yarrow's root ball. If you're improving the soil, mix in some compost or other organic matter to enrich it.

Step 2: Dig Up the Yarrow

Carefully dig around the yarrow plant, at least 6-12 inches away from the base, to loosen the roots. Use a garden fork to gently pry up the root ball. Try to keep as much of the root system intact as possible.

Step 3: Divide the Yarrow (Optional)

If your yarrow clump is very large and overcrowded, you can divide it into smaller sections. Use a sharp knife or shovel to cut through the root ball, ensuring each section has healthy roots and shoots.

Step 4: Plant the Yarrow

Place the yarrow in the prepared hole. Make sure the crown (the point where the stem meets the roots) is at or slightly above the soil level. Backfill the hole with soil, gently firming it around the roots to eliminate air pockets.

Step 5: Water Thoroughly

Water deeply and thoroughly after planting. This helps settle the soil and reduces transplant shock. Continue to water regularly, especially during dry periods, until the yarrow is well-established.

Step 6: Mulch (Optional)

Applying a layer of mulch around the base of the plant will help retain moisture, suppress weeds, and regulate soil temperature.

Troubleshooting Common Issues

Wilting: Wilting after transplanting is normal. Ensure the plant receives adequate water.
Yellowing Leaves: This could indicate overwatering or poor drainage. Check soil moisture and drainage.
Pest Infestations: Yarrow is generally pest-resistant but can occasionally be affected by aphids or spider mites. Treat infestations with insecticidal soap or neem oil.

Maintaining Your Transplanted Yarrow

Once established, yarrow requires minimal care. Deadhead spent flowers to encourage more blooms and prevent self-seeding. Divide overcrowded clumps every 3-5 years to maintain vigor. With proper care and attention, your transplanted yarrow will reward you with beautiful blooms for years to come.
