Crabgrass is a common name a layperson uses for any grass that they don’t like growing in their lawn. However, here in the Northwest, it has been relatively non-existent until recently. Crabgrass is a common annual grass weed in many of the parts of the US where summers are hotter. Due to our cool climate it has not been an issue in the past.
Recently, mostly due to our warming climate, we are now seeing it where we had rarely or never seen it before. Also, due to our long hot summers over the past several years, we have seen it explode on most properties.
Therefore, we are now recommending to treat lawns with a crabgrass preventer in the May as they do in many other parts of the country.
