I'm a homeowner that is new to this forum, and I could use some help identifying a grassy weed that is taking over my back yard. I've attached some pics to try and help. Basically this stuff is spreading along the ground and you can pull it up in clumps. It turns brown in areas and only the tip remain green. Any ideas for identification and control would be appreciated. I live in Michigan

Looks like common bermuda grass.

I have not seen any effective way to get rid of the stuff. I am close friends with one of the biggest Fert/Squirt companies in the area and they have been testing all kinds of products to reduce the infestations here and nothing is providing positive results.

Bermuda in Michigan? I don't think so. I think the frost would kill it, but I've been wrong before. Round-up should take care of it.

i don't know what kind of grass you have the bermuda in, but Sethoxydim (aka Poast or Grass Getter and others, i'm sure) will kill it and bahia, as well. i have killed both in my centipede yard. the grass needs to be actively growing. do not cut the grass for a week or so bf or after application and heed the warnings regarding application in high temps. you will likely have to continue the battle with some type of pre-emergent, as any seeds that have previously dropped will sprout. it may take 2-3 years to totally eradicate it.

As for bermuda in Michigan, I don't go there much, but I do believe it is there. I am constantly fending off bermuda from a neighbors lawn here in the Chicago area. They told me it came from pines transplanted from their michigan home. It's roots can go quite deep and that must be why it survives the winters. I have pulled roots out from 24 inches down.

I have the same thing in spots in Louisville, KY nimblewill I believe is your pain. Common bermuda has much larger stalks with larger foliage. The nimblewill is just as much pain but does not grow near as deep. I use round up but I hate having to do that each year. I notice that if I pull or kill off and use a pre-emergent (lesco is the best) this stuff usually does not win.

Something I discovered this year. It has been very hot and dry here so I took ortho crabgrass killer and sprayed the view shoots of crabcrass in the front yard. I also sprayed the nimblewill. With the temps and sun the nimblewill bit the dust. This only worked in areas that have a lot of sun and direct heat.

The worst part about nimblewill is it will grow as tall as needed to sustain sunlight. The only way to beat it is with a very thick lawn and not cutting too short in the heated months. Good watering habits in the summer to keep your cool season grass happy so it can compete against the bad guys.

OK,

I think I've properly (with great effort due to the fact that I'm not a yard weed specialist like you kind fellows and with the very much appreciated online help of a couple of you guys) identified the two weeds that currently plague my St. Augustine lawn here in the Houston, TX area.

They are Virginia Buttonweed and crab grass.

Gracious, have I on my own and without you guy's help considered my infestations to be any of dozens of what at least I, the untrained I, thought they may be.

Please excuse me if I've unduly burdened any of you with my questions.

I'd really like to purchase a weed-acide that kills both at one time if that's available. And, I'd also like a product which can be used NOW, despite our high temperatures (although our daily temperature highs are moderating a bit here in August...they're still well into the '90s each day).

Again, I apologize for being a PNTA (that's a Marine Corps acronym for pain in the, well, hindquarters). And, I genuinely appreciate your help.

So, if you could be so kind as to point me in the right direction to a post-emergent herbicide to get rid of these two turf weeds at the same time and without me having to await much cooler temperature I would honor you forever.

Best,

David

Well, the subject mystery weed isn't crabgrass after all.

Scotts identified it, without doubt, as Bahaigrass.
