General description

Yarrow is a perennial broadleaf weed. Yarrow adapts to droughty soils that are not fertilized. The foliage is feathery, soft and hairy.


Spreads by seed and rhizomes. When mowed, it forms a thick mat.

Conditions that favors growth

Droughty, under-fertilized soils

Management in lawns

Cultural lawn care practices

Maintain healthy, dense turf that can compete and prevent weed establishment.

Mechanical management

Hand pulling or using an appropriate weeding tool are the primary means of mechanical weed control in lawns. This is a viable option at the beginning of an infestation and on young weeds. Hand pulling when the soil is moist makes the task easier.

Manage Weeds Without Chemicals

Chemical treatment in lawns

Herbicides should be used as a last resort because of the potential risks to people, animals, and the environment. Be aware of these lawn herbicide precautions first.

If you chose this option, spot treat weeds with a liquid, selective, postemergent, broadleaf weed killer applied when weeds are actively growing. Look for a product with one or more of the following active ingredients: 
2, 4-D, MCPP (mecoprop), Dicamba* or Triclopyr.

*Do not spray herbicides containing dicamba over the root zone of trees and shrubs. Roots can absorb the product possibly causing plant damage. Refer to the product label for precautions.
