Start the season right
Plant yarrow in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Yarrow prefers pH 6 to 8 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at its peak
Cut yarrow blooms in the cool of the morning, just as they open, for the longest display.

Where Yarrow thrives
Yarrow is hardy across USDA zones 4 through 10. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Yarrow in my zone?
Yarrow grows in USDA hardiness zones 4 through 10 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Yarrow?
Most growers plant yarrow after the last spring frost, once the soil has warmed. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Yarrow need?
Yarrow does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Yarrow need?
Yarrow prefers soil pH 6 to 8, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Yarrow attract pollinators?
Yes — yarrow's flowers are a strong nectar and pollen source for honeybees, native bees, and butterflies (Xerces Society, Pollinator Partnership).
Is Yarrow safe for pets?
Yarrow is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
