What's the best way to get rid of Yarrow?
Yarrow is fairly resistant to many selective weedkillers, but in lawns, use a weedkiller such as a 2, 4-D-based herbicide to remove the weed. Apply in cool, moist, calm conditions when there is least risk of accidentally damaging nearby garden plants.
How do you stop Yarrow from spreading?
To control spreading by underground stems, just pull up new sprouts—and the attached stem, which is just below the soil surface—as they wander out of bounds. Do this in early spring and during the growing season. It's easier to pull up spreading stems after a rain, when soil is soft.
What kills wild yarrow?
Chemical Yarrow Control
There are several chemicals available for killing yarrow. They must be used during the period of growth from spring to autumn. Dicamba, chlorsulfuron, clopyralid, MCPA, triclopyr, and 2,4D are all listed as useful for yarrow control by the University of Illinois.
How do you manage Yarrow?
Cut back the plant stems in late spring, before the yarrow flowers, to reduce the plant height and avoid that flopping. Finally, yarrow can, in certain conditions, become invasive. Pruning will help keep the plant in check by avoiding self-sowing.
How tall does Yarrow get?
Space the plants 1 to 2 feet apart. They are quick to establish and spread, though some species, like Achillea millefolium, are extra-aggressive growers, so be careful when choosing your plants. Most kinds grow to be about 2 to 4 feet tall.
How do you plant yarrow grass?
A yarrow lawn requires about half the water as grass. For a yarrow lawn on a budget, sow seed in early spring at a rate of 1 ounce of seed per 3,000 square feet of planting area, distributed with a hand spreader. Seeds should sprout within 10 days and bloom the first season.
Why is my yarrow dying?
This happens quite often in my garden as well. The lack of air circulation at the base of the plant is the cause of this darkening and die back. If you don't mind a bit of a messy garden, leave until the flower is done. If you want to clean up the garden, go ahead and cut the plants back.

How fast does Yarrow spread?
The seeds should just barely be covered by the potting soil. Place the pot with the yarrow seeds in a sunny and warm location. The seeds should germinate in 14 to 21 days, depending on the conditions. You can speed up the germination by covering the top of the pot with plastic wrap to keep in moisture and heat.
What colors do Yarrow come in?
Flowers come in a variety of colors, including white, yellow, pink or red. Yarrow plants grow best in full sun and in well-drained soil, but they will tolerate clay soil better than many plants.
Is Yarrow a wildflower?
A member of the aster or composite family (Asteraceae), yarrow has flat-topped or dome-shaped clusters of small white flowers that bloom from April to October. An attractive, hardy perennial, yarrow can reach about 3 feet in height. Its aromatic, fine, feathery-cut leaves give the plant a soft, fern-like appearance.
What is white yarrow?
Achillea millefolium (White Yarrow) is a graceful perennial wildflower which produces an abundance of huge, flat clusters, 5 in. across (12 cm), packed with 20-25 creamy-white flowers. They are borne on tall stems atop a pleasantly aromatic, green, fern-like foliage that is disease resistant.
