    Here in the Northwest, I have alot of accounts with Kentucky bluegrass-- 1 Of my accounts has popped up with a couple of patches of what looks like Bent Grass, about 3' round (and spreading)... How do I get rid of it?? or what can I do to control the spread? :)

    I actually posted a thread on this subject a while back. Those patches are a pain in the a**. They spread fast. My yard had a patch the size of a dinner plate 5 years ago and now it is the size of a small putting green. Ive talked to truegreen and they say it is for sure bentgrass.

    What to do! - buy the concentrated roundup and mix it in a sprayer at twice the recommended rate. Wait until the grass begins to grow and looks green and healthy. Spray areas generously. Two weeks later mower + bag area at a short height. Wait a few weeks and spray the area again. Seed two weeks later and thats it.

    That tends to get most of it but what I did last year is after I sprayed it the first time and mowed it, I waited like 2 months to see if it came back before spraying again and seeding. Hope this helps

    Bent grass is tough because it is a domestic blend, lawn hebicides are formulated to not harm it, since some people use it for their entire lawn. I'm just South of you here in Utah, here's what I recommend spray Round Up just like Snap12.5 suggested, wait about 1-2 weeks then dig it out and replace it with sod. A couple of peices of sod would be cheap and you get your lawn back a lot faster, plus if the Round Up leaves any living bent grass roots, they will be less able to compete.
