Can someone please tell me how to get rid of poa annua (annual bluegrass) in fescue lawns.
Spot treat with glyphosate?
It's growing throughout the lawn. Round-up will leave dead spots everywhere plus it's producing seeds so it will be back next season. A pre-emergent in the fall will block it but that't the same time I will need to overseed with fescue.
On the golf course we used a liquid product called Trimmit on our Bentgrass greens, to limit Poa. Also, Scotts makes a granular fertilizer for the same purpose, I think it's called TGR High K Fert.
I'm not sure of the use of either product with Fescue, because I never had to worry about that.
These products won't "kill" Poa, but will weaken it with repeated apps enough to allow the other grasses to fill in.
Hope this helps.
Welcome to the board.
Has anybody removed the poa by core- aerating. Doesn't poa like hard ground??
Prograss (ethofumesate) will kill poa.
How does it react with other cool weather grasses (I have a mixture of fescue/blue/rye)? My own yard is starting to get hit with poa.
You can sure help prevent some of it by aerating regularly. Poa loves compacted soil.
It likes a wet soil, too ... there are spots in our (sand) yard that used to be infested with PA, due to the wetness.
