we have the same problem, they are horrible little tufts, but luckily easy to pull. This is the first year I've seen this invasive weed. One of the reputable lawn service companies told us they don't have a spray for it.

When will it die? The man told us the soil temperature has to be at least 68.

Hate the stuff

So that's what that stuff is! I pull and pull but it makes so many seeds early it comes back every spring. From where it's located I know I probably got it in some plant from a nursery.

I've written to the Agricultural Center for Forsyth County and someone there is supposed to get in touch with me. One of the caretakers at the golf course said, they spray it before their Bermuda comes back and the spray doesn't hurt the Bermuda...but once everything is growing, there isn't much you can do for it. It usually dies back in the heat of the summer. From another site someone sent information that a vinegar spray kills it. This I don't understand and will wiat to hear from Forsyth County Agr.

You can put down a preemergent for it (like Scotts Halts) in the fall. Problem is that you can't reseed the lawn if you do that.

My lawn's only 4th season and we've been fighting it for the past three years. I'm convinced it comes in on the wheels of our lawn service mowers. Poa Annua(commonly called 'poanna' Annual bluegrass. Gazillion seeds. I've had luck pulling it out early in the season but it's an 'on your knees' job and it could be you're just making a nice hole for a nearby seed from last year to start up.
If you have a lawn service, you'll never get rid of it because their blowers send the seeds into the borders.
At least there it's easy to pull.
Good luck next year with the Halts and let us know if it works.

Poa annua seeds can lay dormant in the soil for years, so annual applications of pre-emergents are necessary if the outbreak is bad. Waiting for the hot weather to take this annual bluegrass out allows the plants to go to seed.

The vinegar spray acts like a contact herbicide. It will (maybe) kill the poa but is a spot treatment. It will kill surrounding grass, too. Spot treatments of any contact herbicide will do that. This can be a perfectly acceptable solution to this problem. Your lawn will be spotty for awhile, but should be able to recover.

Any 'reputable' lawn company will be able to explain that there is no herbicide that can take growing poa out of growing lawns, without damaging the lawn. It is the pre-emergents, carefully timed, that do the job.

Maintaining your permanent lawn at its highest quality is also important in controlling poa annua. If you keep your healthy, vigorous lawn mowed at a tall level (on a regular basis), it can shade out the poa seeds. Also, a healthy stand of grass can recover quickly if you have to attack a bunch of poa plants with a contact herbicide.

I brew my own vinegars (another long story) so I have access to plenty of full strength vinegar and I have tried it as an herbicide and it hasn't killed anything I've sprayed it on. I haven't wasted precious chemicals on it to test its strength but it burns your finger tips when you touch it so it has to be plenty strong. I was hoping for a more eco-friendly spray for poison ivy.

We have Poa Annna Grass all over my centerpeed grass? Have been told there is a chemical that you can use to spray, but it takes several applications to completely get rid of it. WHAT IS THE NAME OF THE CHEMICAL SPRAY ..... I use to know when I lived in another home, but have forgot the NAME?

I live in GA & poanna has taken over my lawn! Can I till up the poanna,plant grass seed & then apply pre-emergent in september?
