Plant

Spring-plant divisions or transplants. Full sun, poor soil — yarrow hates rich, wet conditions.

Care

Cut back after first bloom to force a second flush. Divide every 3 years to keep vigor. Nearly indestructible.

Harvest

Cut when the flat-topped heads are fully colored. Excellent filler in bouquets, dries perfectly.

Preserve

Yarrow dries beautifully — hang upside down in a dark spot for wreaths and winter arrangements.

Companion planting

What yarrow likes, and doesn’t.

Good neighbors

  • Roses (deters pests)
  • Perennial borders
  • Vegetable garden edges

Avoid nearby

  • Nothing significant

Yarrow attracts hoverflies, ladybugs, and predatory wasps — a low-maintenance pest control anchor for borders.
