Yarrow (Achillea millefolium)

What does it look like?:  Yarrow is a low growing perennial with wispy leaves similar to small ferns.  The flower stalks are much taller, and slightly hairy.  The flowers are typically white, but may be pink or yellow.

What causes it?:  Yarrow is not always considered a nuisance.  It is commonly used for medicinal purposes, and is welcome in many landscapes.  However, when it invades the lawn, it can be hard to get rid of.  It spreads via rhizomes and seeds.

When does it show up?:   June through August

Best treatment plan: Hand-pulling is effective for minor infestations, but post-emergent treatments from spring to fall will help as well.  Keeping lawn turf strong and thick will discourage this plant from growing. Call a professional for a free quote.

How long will it take to get rid of it?:   This can take a long time, as the seeds can remain viable in the ground for up to 9 years!
