Yet another what's this ugly/different grass thread!

Here are two pictures. Most of the lawn is normal, but there are patches and groups of this second grass which has blades facing different directions, but about the same color, slightly lighter and broader, as the healthy bluegrass. This different variety seems to have one stem, but several blades, hence they point at different angles. Sorry the pix are not sharp.

Is this seasonal? What if anything to do?

That looks like crabgrass but the picture is so blurry it is hard to tell

Yuck... they are blurry. Will try CG killer on an area, and if no success, will repost pix.

Crabgrass control

If it's crabgrass, here's a good webpage on crabgrass: https://www.wikihow.com/Get-Rid-of-Crabgrass

Maybe it's Bermuda Grass.

Sprayed both lawns with triclopyr.... 3 tsps./gallon over 1,000 sq. ft.

So far, so good.

Tricyclopyr is indeed selectively killing the abnormal grass. Hope the bluegrass grows back into these areas.

You mean diagnosis by treatment? Or the appearance of success?

Yikes--- this might be bent grass

The chemical stopped working, and a grass professional said it looks like BENTGRASS. What should I do? What can I do (myself) ?

Spray with an everything killer. Wait till it dies then in 2 weeks later plant grass that you want.

1600 sq. ft. !! Using RoundUp and replacing all the grass would be over $3,000

Why not use Tenacity ?

Why not just keep the Bentgrass ?

I was saying spot treat it and kill the bentgrass you want gone then plant the seed. You do not have to kill everything. But if you like the Tenacity idea try it. I do not like bent frass. It does not grow tall to get a plush grass but to each his own.

Okay. Will spot test Tenacity tomorrow. Bentgrass is a bit ugly. It forms like a web above ground, seems a lighter green, and the blades are not uniform.

It may not be an abnormal grass at all !

A gardener was in the area and he seemed knowledgeable.

He said the growth is "normal". He thinks it is MEDALLION GRASS. (never heard of it)

I still will try Tenacity in a small area.

Nimblewill is what I found. Also known as Wiregrass and Dropseed.

How did you ID it? That weed app ?

You hit the nail on the head: https://www.google.com/search?tbm=i...0.0....0...1.2.64.img..0.0.0....0.AMKjYLY8lq0

Yes, I always use the weed app. Love that thing.

The lawns look good despite this Nimble. What happens if nothing is done, that is one does not attempt. Go kill. The Nimble?

Chemical control. Presently only one herbicide available to homeowners, Tenacity (active ingredient mesotrione), provides selective control of nimblewill in cool-season lawns such as Kentucky bluegrass, tall fescue, fine fescues and perennial ryegrass. Application rates can vary so follow label directions. It is not approved for use on warm-season grasses such as zoysia grass. Several applications are needed for good control and a non-ionic surfactant should be added to the mix. Nimblewill will become bleached and white as it dies.

A cheaper control method is to apply a non-selective, post-emergent herbicide such as glyphosate (Roundup) to patches of nimblewill and then replant the areas. Apply the herbicide when the nimblewill is actively growing during the summer. Applying in late autumn to early spring when it is dormant will not provide control. Glyphosate, being a non-selective herbicide, will kill desirable lawn grasses as well.

Sounds good. You should author the product label.

So do some people have pure Nimble lawns because the weed was never treated?

2 of the yards I used to mow were. I had to stop because I kept moving it to other yards.

Did the 100% Nimble Lawns look good? Maybe I should not have sprayed the 25% of my lawn.

Here is 15% of the lawn from far away and NOT treated (yet) with Tenacity®:

The color difference is noteworthy, but neighbors say it's the best lawn in the neighborhood.

No, it looked like total crap. They were not taken care of lawns. Weeds everywhere.
