Brief Description: Known more commonly as annual bluegrass or simply poa, is a widespread low-growing turfgrass in temperate climates. It has a slightly creeping, fibrous, rootstock. The stem grows from 6-10 in. high. It is slightly flattened, due to being folded rather than rolled.

What is Poa Annua?

Poa Annua, or annual bluegrass, is one of the most common grassy weeds in the United States. It looks very similar to Kentucky bluegrass, except it is a lighter shade of green, has a shallower root system, and develops a short seed head early in the season. It usually dies off in the summer when the weather gets hot, leaving behind bare spots in your lawn.

How to Prevent Poa Annua

The Poa annua seeds produced in the spring wait patiently in the soil for the cooler temperature of fall to arrive before they sprout. You can stop them from sprouting by applying a pre-emergent weed control product in early fall (Aug – Sept). You can also target the existing weeds with a post-emergent to rid your yard of this pesky weed.
