Yarrow Seed

Germination

10-14 days at 65-72°F (18-22°C) 

Days to Maturity

75 – 80 Days

Sowing

Transplant (recommended): Sow 8-10 weeks before last frost. Do not cover seed as light is required for germination. Bottom water or mist lightly to avoid covering the seed with displaced soil. Transplant to cell packs or 2-4″ containers when the first true leaves appear, approximately 3 weeks after sowing. Harden off and transplant outside after the last frost.
Direct seed: Sow seed in late spring, after late frost, early summer, or fall. Thin to stand 12-24″ apart. Support may be necessary.

Soil Requirements

A sandy, moist, well-drained loam.

Seedling Care

Grow seedlings for 3-5 weeks at 70-72°F (21-22°C) in full light. Seedlings grow quickly and should be given their own 4″ pot or planted in pairs of plugs. The more quickly you transplant up your yarrow, the more healthy it will be.

Light Preference

Full Sun (6 hours of direct light or more)

Hardiness Zones

Zones 2-9

Harvest

Fresh Cut: Harvest when pollen is visible on the flowers. Cut in the coolest part of the day.
Medicinal: Yarrow leaf and flower is harvested together when plants are in the early stages of flowering by hand cutting with a field knife. Materials dry within 24 hours under low ambient humidity on open air drying racks.
