Poa Annua is an annual bluegrass that is often considered a weed in turf, due to its light green color and seed heads that are produced no matter what height the grass is planted at. When looking for how to prevent poa annua from growing in your lawn, pre-emergent applications in the late summer and fall are essential. Because fall is the best time to seed, you often need to make a decision on whether you want to prevent poa annua with pre-emergents or seed your lawn, as most pre-emergents will prevent grass germination as well. Poa Annua pre-emergence applications should be started in late August before soil temperatures drop below 70*, as poa annua begins germinating below this temp. A second pre-emergent is recommended in November so that control last through till spring, as poa annua is a winter annual that can even germinate under snow cover. When looking for how to control Poa Annua post-emergently, control can be achieved with a few specific professional selective herbicides that require regular interval treatments and are generally specialized, or with non-selective herbicides which will kill poa annua and any desirable plants as well.

In certain environments with heavy clay soils, shade, poor drainage, or heavy watering such as golf course greens poa annua can be kept alive throughout the growing season and become a much more troublesome pest.
