Tips On Growing Achillea (Yarrow)
Achillea (Yarrow) are long-blooming, Old World perennials that are exceptionally easy-to-grow and provide ample nectar for butterflies. They are resistant to browsing rabbits and deer. Most are tall, upright growers with the exception of evergreen Achillea ageratifolia (Greek yarrow) and Achillea millifolium ‘Sonoma Coast,' which are groundcovers.
Preferred growing conditions:
- These perennials grow in most any type of soil including clay.
- Should be mulched in dry climates with most any type of mulch materials including gravel in xeric plantings.
- Only requires deep but infrequent watering after their second growing season. Too much water makes them floppy.
- Plant in full, hot sun.
- Adding just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. Avoid planting into a rich, highly-amended soil; they don't need it and it can make them floppy.
- Deadhead plants to prolong bloom.
- Achillea millifolium 'Sonoma Coast' is a superior lawn grass replacement and should be mowed to deadhead it after blooming in early summer. This keeps the foliage tidy and looking good.
- Fertilize Achillea once in fall with Yum Yum Mix and Planters II.
- Leave Yarrow standing over the winter. They have ornamental flower heads that catch the snow providing winter interest. Cut back to 1-2" inches above the soil in mid-spring when the plants begin to wake up.
- Achillea ageratifolia (Greek yarrow) is an evergreen groundcover that should NOT be cut back other than to deadhead it in early to mid-summer to encourage re-blooming.
- Plants can be divided in mid-spring when clumps die-out in the center or become too large for their place in the garden.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
