How do I identify Poa annua?
Poa annua is light green in color with coarse textured leaves and products unsightly seed heads. Both annual and perennial types exist. Perennial types are more common in areas that are watered frequently, and fed lots of nitrogen. It is also common in areas with lots of shade or that are compacted.
How do you get rid of POA Trivialis?
It works best at temperatures above 75 F, and it’s best to treat in spring to mid summer.

Poa annua is bright green and will appear much brighter that your lawn. Poa annua has smooth leaves with a pointed “boat shaped” tip. Poa annua grows in clumps, or a bunch-type pattern. You will not find poa annua growing in individual blades, but always in clumps.
What is the common name of POA Trivialis?
rough bluegrass
Poa trivialis, commonly called rough bluegrass, is a cool season, creeping (by stolons only) turfgrass that is noted for its ability to do well in moist soils and shade.
How do I get rid of poa annua in my yard?
Most people choose to control poa annua with a pre-emergent herbicide. This is a herbicide that will prevent the poa annua seeds from germinating. For effective poa annua control, apply a pre-emergent herbicide in early fall and again in early spring. This will keep the poa annua seeds from sprouting.
Where is POA Trivialis from?
However, we now know there are also perennial types of Poa annua that will live through the stress of the summer, primarily in northern Illinois and Indiana. Poa trivialis is a perennial grass that spreads by stolons (creeping, above-ground stems) forming light green patches in turf.
Is POA Trivialis bad?
Poa trivialis likes the cooler weather of fall and spring, and is typically most aggressive in shady lawns that hold onto too much moisture (whether that’s due to overwatering or poor drainage.) Even if Poa trivialis is really pervasive in your lawn – it will die back in the summer heat.
How big does a Poa trivialis Culm get?
Identification: This grass is perennial, short-lived, somewhat loosely to densely tufted, usually weakly stoloniferous, with basal intra-vaginal branching . Culms are 25-120 cm, decumbent to erect, sometimes trailing and rooting at the nodes, terete or weakly com-pressed; nodes are terete or slightly compressed, (0)1-3 exserted.
What’s the difference between Poa trivialis and Kentucky bluegrass?
Compared to Kentucky bluegrass, it has a lighter color, and the “boat-shaped” blade tips are more pointed. Also, Kentucky bluegrass does not produce stolons. Poa trivialis reproduces primarily by stolons, a creeping horizontal plant stem or runner that takes root at points along its length to form new plants.
What can Poa trivialis grass be used for?
Poa trivialis is widely planted as a pasture grass. It is used for forage hay and pasturage in marshlands. There are no known regulations for this species.
When does Poa trivialis die out in Maryland?
Although once established, it will spread into sunnier, drier sites. Poa trivialis also tends to die out during the heat of the summer months leaving thin areas in the turf before re-growing in the cooler fall season. Roughstalk bluegrass has a membranous ligule.
