So i have two major areas in my lawn. One area that is in the back and ALL SUN ALL THE TIME. KBG grows there. However, every year there are larger and larger circles of something else in there. I've been thinking it might be nutsedge, goosegrass or quack grass. I put down a pre-emergent but that doesnt seem to help. I hit it HARD with tenacity and that didnt do anything either. Maybe its fescue, but that would be odd since more spots are showing up and they are growing and fescue doesnt expand.

When everything else was also growing:

Near end of season:

Then I have a second spot near my firepit where its mostly tall fescue. I have 4 very mature ash trees here giving tons of shade. However, something else is popping out and outgrowing the fescue. This area is very wet and hard to mitigate.

Please please help. TLF, you are my only hope.

Welcome to TLF. I'm in a very slow connection in the Caribbean, so I'm struggling to download all the images. It those patches look like quackgrass from a distance. Try to get an image of the auricle.

If it is quack (which you still need to confirm), then round up is the only option.

I'm with g-man if weedy plant has clasping auricles it's quack and run for the round up

 

[Belgianbillie]

quack where. We are talking about two different areas of the lawn here.

I think all the pics you posted from both areas are probably quackgrass. Like g-man and Turfguy93 I think round-up is the only way to go.

That would be an acre of grass as its everywhere.

Are there no other solutions for quack grass at all?

So people with large lawns, once they get quackgrass spread its fucked for eternity unless they are willing to redo their whole lawn and even then its a crapshoot bc it can just come back in from the neighbours.

There is a product called Certainty, but it will have negative effects on your cool season grass. You are better off nuking with Roundup.

Try to confirm the I'd of it. Let's see images from the auricles. Are they clasping?

Also, once you get rid of it, it normally doesn't come back. I think you had it for a while and it grew in size.

 

[Belgianbillie]

It has not started growing yet this year but i will look when i can.

It always grows much faster than the surrounding grass.

Maybe this is something i can do?

The 'wicked' technique is used by professionals across a large area- it consists of a 'ropewick' tool that paints herbicide on the tall leaves of the quackgrass, leaving most of the desirable grass untouched.

 

[g-man]

Yes, the wick method and others work. Plugging the bare spots helps the area recuperate faster.

 

[ABC123]

The lesser approach will be mowing properly and light N applications to help the bluegrass compete with the quack.

I had a large lawn of 40%+ quack and it took 2 years to make it get down near 5%. Nothing in lawn care happens over night, it will be a slow battle.

Clasping Auricles would not be 100% indicative of Quack. Annual (Italian) Ryegrass also has clasping auricles, and similar (Spike) seedheads and leaf structure. Given your location in SE Wisconsin, which for the most part is cool and wet (compared to say Middle Tenn.) Annual Rye will not die in the summer. Sadly, roundup is still the likely route.

I only interject this for future reference to others who might stumble across this thread. Just because something has a single trait, does not mean it's a particular grass / weed, and could have a different strategy for treatment.
