Yarrow (Achillea millefolium) is a tough, native North American perennial beloved by pollinators and gardeners alike. With its flat-topped clusters of tiny flowers and ferny, aromatic foliage, yarrow thrives in borders, cottage gardens, pollinator patches, and open meadows. Drought-tolerant and low-maintenance, it’s an excellent choice for sustainable landscapes. Here’s how to grow yarrow successfully in your garden.

Because yarrow is native across much of North America, it’s a valuable plant for sustainable gardens: it supports pollinators and beneficial insects, tolerates lean soils, and fits naturally into meadow plantings and low-water landscapes. If you’re aiming to garden responsibly, consider choosing native or regionally adapted yarrow when possible and avoid planting aggressive spreaders near natural areas.

Yarrow is pest-resistant, drought-tolerant, and highly attractive to butterflies and beneficial insects. The long-lasting blooms are excellent for fresh bouquets and dried arrangements.

Planting

When to Plant Yarrow

  • Plant in spring or early summer after the danger of frost has passed. See local frost dates.
  • Start from nursery plants, divisions, or tip cuttings in spring.
  • Seeds can be started 8–10 weeks indoors before your last frost date.

Choosing and Preparing a Planting Site

  • Plant in full sun for compact growth and abundant flowers. In partial shade, plants may become leggy.
  • Yarrow prefers well-drained soil and thrives in hot, dry conditions.
  • Avoid constantly wet or poorly drained soil, which can lead to root rot.
  • Loamy soil is ideal, but yarrow tolerates clay soil if it drains well.
  • Loosen soil 12–15 inches deep and mix in 2–4 inches of compost before planting.
  • Avoid overly rich soil; too much fertility can cause floppy stems.

How to Plant Yarrow

  • Space plants 1 to 2 feet apart to allow for spreading.
  • Most varieties grow 2 to 4 feet tall.
  • Water well after planting to help roots establish.

Growing

Watering

  • Yarrow is very drought-tolerant once established.
  • If rainfall is less than 1 inch per week during summer, provide supplemental water.
  • Avoid overwatering.

Feeding

  • Apply a thin layer of compost each spring.
  • Additional fertilizer is rarely necessary.

Deadheading and Pruning

  • “Deadhead” spent flowers in mid-summer to encourage a second bloom.
  • After flowering finishes, cut plants back to tidy growth and sometimes stimulate fall blooms.

Dividing Yarrow

  • Divide plants every 3 to 5 years in early spring or fall.
  • Lift clumps, remove woody or dead centers, and replant healthy divisions.

Harvesting

Harvest flowers when they are fully open but still vibrant. Cut stems in the morning after the dew has dried.

  • Hang small bundles upside down in a dark, dry, well-ventilated area.
  • Alternatively, use a dehydrator on a low setting.
  • Store dried flowers in airtight containers away from light.

Pests and Problems

Yarrow Problems

Yarrow is a hardy, low-maintenance perennial and is generally resistant to pests and disease, making it a dependable choice for many gardens.

However, problems can occasionally develop, especially in overly wet soil or crowded planting conditions. Yarrow performs best in full sun with excellent drainage and good air circulation to stay healthy and vigorous.

Yarrow Pests

Yarrow may occasionally attract a few common garden pests.

Aphids can cluster on stems and flower heads, feeding on plant sap and causing distorted growth. Encourage beneficial insects like ladybugs to help control populations naturally

Yarrow Diseases

Yarrow is usually disease-resistant, but a few issues can appear under the right conditions.

Powdery mildew may develop in humid or crowded settings, appearing as a white coating on leaves.

Rust can cause orange or brown spotting on foliage.

Stem or root rot may occur in poorly drained soil, especially during prolonged wet conditions.

To prevent disease:

  • Space plants properly for good airflow
  • Avoid overhead watering
  • Plant in well-drained soil
  • Remove affected foliage promptly to reduce spread
