Podcast with a person who has studied it and controls of it. Talks about NY primarily but also N. WI.

His take, let it go, it will gradually disappear leaving just a few stragglers.

What to control instead. Many here won't like it but Deer are bigger problem.

Earthworms, Garlic mustard and deer and their relationships.

Interesting listen.

It's spreading like wildfire. I can't imagine just letting it go, but that's what people around here are doing.

Maybe a biocontrol can be found.

Eventually garlic mustard toxifies the ground against itself. That's what happened on my farm. It was very prevalent in my ditch row in 2012. Now I only see it rarely, in an unmowed area, where it wasn't before.

The yard and surrounding area is full of it, I have the yard mostly clear now, both hand pulling and Glyphosate....you can eat it it's claimed.

We were getting a good handle on the garlic mustard at our gun club pre 2018. Then a tornado went through, We had some clean up logging done. We now have acres of garlic mustard, way too much to do anything about. You'd need a small army to hand pull all of it every spring for 5-7 years.
I guess we'll see what happens with it.

Ive noticed alot of yellow mustard in hayfields in my area iam not sure why never used to see it in hayfields before.
