Yarrow [Achillea millifolium]

Click to enlarge image
Yarrow is a perennial weed that is very common on all types of lawn as it can easily tolerate close mowing. It has deep fibrous roots making it a very drought resistant weed. It can be a difficult to control with chemicals as it resistant to many weed killers.

Once yarrow is established in the lawn it can spread very quickly by seed and underground runners choking out the grass.

Yarrow leaves are fern like and give off a fragrant smell when they are crushed.

The small white flowers are formed in clusters and can be seen from June to October.

Yarrow will grow in most types of soil, but prefers dry soils often deficient in nutrients. Yarrow is often a good indication that a lawn is low on nutrients and requires feeding.

Hand weeding can prove difficult with yarrow unless there are only a few plants.

Mowing the lawn at a sensible height will remove the seed heads before they flower and at the same time encourage a thick dense sward of grass.

Apply a balanced fertiliser program to encourage a healthy lawn that will suppress most lawn weeds.

Yarrow can be a difficult weed to control with a selective weed killer as it is moderately resistant to most products. In almost all cases more than one application will be needed to control this weed.

When using chemicals in the garden always wear the correct protective equipment and clothing.

It is important to read the product label and follow the manufacturers health & safety recommendations and application guidelines.
