Poa annua grass is a big problem in Texas lawns
It has a tendency to die during long bouts of hot weather, leaving brown patches in a green lawn. This is frustrating for property owners who have worked hard to have an attractive yard. The good news is that although it is difficult to kill Poa annua grass, it can be done.
You’ll be able to spot Poa annua grass by its tasseled seed stalk, which is typically taller than the surrounding turf. It usually starts to make itself apparent late in the spring or early in the summer. However, when the heat really kicks in, it turns brown and dies. If you had any doubts about having poa in your yard before, you definitely know what you’re dealing with now.
Poa annua is sometimes called annual bluegrass, and it is difficult to control. A single plant produces hundreds of seeds in just one season. Unfortunately, the plant can continue to produce seeds even after it is mowed down. Sometimes those seeds germinate quickly. However, it’s not unusual for seeds to remain dormant for several years, making the property owner think that the problem has been eradicated. Then, it crops up again in the spring, causing huge amounts of frustration.
Timing is central when it comes to controlling poa annua grass. The seeds may germinate either late in the fall or early in the spring. Applying pre-emergent herbicides at both of these times may be the best way to get a handle on the problem. This type of herbicide actually prevents the seeds from being able to complete the germination process. Accordingly, you can expect to see fewer poa annua grass plants in your lawn when the spring arrives. It is important to keep in mind that these tough seeds can survive for several seasons, so it is essential to control the problem by applying the pre-emergent herbicide repeatedly.
