This year’s first enemy

Yeeesh is that your yard? Pretty sure it’ll die off in a few weeks. Just use pre emergent next year.

Yeah, I have the crap everywhere. Roots are shallow and easy to pull up but need to know as well what to put down to kill it. I would think some type of fall and spring emergent would do it but need to know what to get.

Thank you. Looks like Atrazine may be my weapon of choice, then reshape and reseed that area.

Apply a pre-emergent herbicide this fall (Sept/Oct) to greatly reduce your Poa issue next spring - all those seeds you see on that Poa will be germinating next fall/winter, won’t eliminate the Poa but will significantly reduce it.

We taking what for st aug? This is what I have as well.

I used some Image on what was left of mine after using prodiamine for pre-emergence last fall and 2 or so weeks later it has finally died off.

Prodiamine, Dimension (dithiopyr) or Simazine are all effective pre-emergent herbicides for Poa annua and many other weeds in St Augustine, Centipede, Bermudagrass and Zoysia lawns. Major downside downside of Simazine for the homeowner is the smallest quantity you can purchase (to my knowledge) is 2 1/2 gallons, and the amount required per 1000 sq ft of lawn is small, so maybe best to go with prodamine or dimension. You can buy these in granular versions if you prefer that approach to the spray versions, but more expensive per 1000 sq ft.

POA. Will die with heat. Use pre emerge next year

Fun fact about poa annua:
It's the grass used on the greens of world famous West Coast gold courses such as Pebble Beach and Cypress Point
