It might be a little early for the application, however it’s a good time to start planning for this application in September – October. For a pre-emergent to be effective it needs to be applied prior to the germination of seed. Poa germination can occur in certain areas even in mid to late August and is highly dependent on the environmental conditions for each year. Frequently soil temps will start to drop and Poa will begin to germinate. Due to environmental stress poa will not generally grow out in the canopy for another 30-60 days when temps have fallen inline for more favorable growing temps. A combination of a post and pre-emergent will generally give higher rates of success and prevent additional applications needed to clean up winter grassy weeds.
