How does POA Trivialis spread?
Poa trivialis is a perennial grass that spreads by stolons (creeping, above-ground stems) forming light green patches in turf. Some believe that Poa trivialis grows naturally over most of the world and Poa trivialis seeds or stolons can germinate after lying dormant for many years, thus contaminating a turf stand.
Are POA Trivialis shallow roots?
Poa trivialis is shallow rooted, has poor wear resistance, is extremely susceptible to dollar spot, and often goes dormant with the heat of July and August. None of these qualities make for a good summer or fall use sports field. Reseeding may be needed depending on density of Kentucky bluegrass or ryegrass.
Can you choke out POA Trivialis?
Poa trivialis is a light green grass that creates thick mats of stems, choking out areas of lawn. Because of the off color and rapid growth it is aesthetically unappealing, as are the large bare spots it can leave when it goes dormant in summer.
How do you control Poa Trivialis in fescue?
By mowing at a high setting, watering deeply, and employing a turf management program like PPLM’s that reduces compaction and thickens turf with organically based, carbon rich treatments, a lawn will be more habitable for the desired fescue and less habitable for undesired poa annua, poa trivialis, and other weeds.
What kind of grass is ” Poa trivialis “?

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.
Why are Poa trivialis seeds missed by quality control?
That’s because Poa trivialis seed is small, and it slips through the screening process. And since it resembles the seeds of other shade grasses, it’s routinely missed by quality control.
Is there any way to get rid of Poa trivialis?
Poa trivialis is a tough weed to treat for a few reasons. First, there aren’t any selective Poa trivialis herbicide treatments, which means that whatever herbicide you put on the weed will also kill the grass around it.
