Does anyone know how I can easily kill the nut-grass in my dichondra?
Can't always pull the nut out. I'm trying to brush on msma. I'd like to know if there is something I can spray on it with out killing the dichondra.

A herbicide sold under the name SedgeHammer should kill the nut-grass without harming the dichondra. You might want to try it in a small area first, though, to be sure.

I'm skeptical about ever getting rid of nutgrass. I'm also skeptical about SedgeHammer doing the deed. I tried it once a few years or so ago and it only made a temporary dent in the nutgrass. I don't know if it would do any harm to your dichondra or any other surrounding plants. I only know that getting rid of nutgrass is a real booger.

If you've ever pulled or dug any up then you might have seen the first nut. And maybe even seen the teeny tiny little root that has another nut. And another. It can grow them down as well as down and across. Too bad the squirrels won't help.

Would like to hear back if you find that SedgeHammer or anything else works on nutgrass. Thanks.

Good luck!

The nutgrass sprays dont kill the seeds below. 👺 arrr !!! 👺
I've been trying this year. Using straight round-up and a pencil paint brush. Paint the hell grass . It works for quite a while. Re apply when babies come up. I believe its gonna work. Please test one spot first !
Because ! I believe inter-twined roots of other plants are a somewhat affected. Not killed.but look a little sick for awhile.
Welcome! I tip my hat to you.

I learned about Sedgehammer from @KentPfeiffer a couple years ago and I can assure you, it DOES work and it is extremely effective. I still get nutgrass coming up here and there that I have to spray (in other words, I haven't completely eradicated it) but the results are indeed nothing short of miraculous. It is expensive but worth its weight in gold.

I suspect it does. We had an incredibly bad infestation and after a couple years of repeated applications, we are probably down to only 10% of the original amount of nutgrass. I truly believe eventually we'll be 100% free of it.
