My neighbor is infested with poa t. Has no desire to kill it off. Waiting for the infiltration… is there a defense strategy other than gly immediate invaders?
Do you have a picture of your line of defense?

Anybody with some advice on how many round apps I need to spray. Hit it with two so far and have a bunch of patches I need to scratch and throw down some seed soon.

Someone mentioned on one of the earlier pages that they sprayed Round Up and then hit their turf with a pre emergent in the fall and they haven't seen it since. Can anyone comment on what pre emergent that might inhibit the start of triv
Doesn’t make sense to me unless pre-em can prevent stolons from coming above ground. I’ve not seen Triv seed.

Here’s a poa triv with seed head. I’ve pulled others as well.

How is your trivialis getting that tall in the lawn? Is that from your beds?

The bigger ones are in the lawn border next to the natural area. Here’s another larger one with seed heads growing in the stalks.

Last year I used roundup and destroyed the front of my lawn trying to beat this weed. Didn't really work. I'm defeated. So I want to know how to live this this in a Tier 1 lawn and manage with cultural practices?

Specifically, since pulling doesn't work, has anyone tried drought stressing a TTTF lawn in the summer, and then pulling / raking up poa triv, stolons and all? I mention water restriction since the root structure should be less that the desirable grasses?

I know I'm probably delusional but I'm not going to glyphosate 1/3 of my lawn again.
