Grassy Weed – Annual Bluegrass

(Poa annua)

Annual Bluegrass – also referred to as Annual Meadowgrass, Annual Spear-grass, and Wintergrass – is an annual grassy weed. Due to the fact that this plant is often sold as a turfgrass and is able to adapt to different climates and growing conditions, Poa annua can be found in a wide range of habitats throughout much of North America.

Identifying Annual Bluegrass -

Annual Bluegrass can be identified as a bunch forming turfgrass that grows in dense patches. Its ligule is medium to long and slightly pointed, while its collar is narrow and smooth. It has sheaths that are slightly compressed, smooth, with short blades that have parallel edges terminating in a boat-shaped tip. The seeds germinate in late summer, early autumn and spring.

Annual Bluegrass Control -

Annual Bluegrass is a grassy weed that is difficult to control culturally. It has the ability to adapt to numerous lawn mowing heights, which is a large reason why it is used frequently on golf course greens and fairways. Professionally applied, pre-emergent herbicides are the best way to control annual bluegrass.
