Annual bluegrass removal

5 years ago

Well... I've learned something today. A LOT of the unknown weed that I have in my back yard is annual bluegrass, which came from some of the cheap multi-mix seed that I've been sowing for several years!

Granted it's soft to walk on, stays short, and really not that attractive. But the roots are very shallow (which has caused a multitude of other problems), it spreads outward like crabgrass (so a single root ends up covering about 8" of lawn), it dies away in the winter (leaving me with several months of a mud pit), and when it goes to seed my dog is definitely allergic to it!

I've been hand-pulling for a few months, but that's slow going and I've successfully pulled maybe 10%. And now that it's seeding, it's probably too late, anyway.

Any suggestions on permanent removal without killing the tall fescue that I've been sowing?

I'm in zone 7A, western NC near the mountains.

You're the guy reluctantly growing bermuda right? I have been using this product for my St Augustine lawn for a few years.

It is not recommended for bermuda grass; however, I have sprayed and sprayed the encroaching bermuda in my lawn and nothing happens to the bermuda. One thing that did happen was all the annual rye grass died right away and NEVER came back. It killed all the seeds too.

Tenacity is for grassy weeds. A bit pricey when I bought it but maybe it is a little cheaper now. Make sure it won't harm your preferred grass first.

I'm afraid you have me mixed up with someone else... I don't intentionally have any bermuda grass anywhere. I sowed Kentucky 31 last Fall and this Spring, but as I'm progressing I'm starting to think that it was a huge mistake :-( So I'm not sure that I have ANY grass right now that I want to save!

I'm going to start a new thread tomorrow with some pics, but right now I'm very close to scraping it all up and starting over.

You might want to try the Atrazine product anyway if you have K-31. It might kill everything and it's offspring for you.
