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.
