Nut grass in the garden or yard is a pain. You pull it out and it comes back. Most ordinary weed killers don’t work. So what do you do?
I’ve found a product called “Sedge Hammer” which really does work. It’s not cheap, but it’s better than spending hours in the garden trying to dig it out.

I have read (but not tried as yet) that simple old household sugar will kill it. I have it trough my vegie patch and will try it on that and keep you informed as to the results.
help — this stuff has taken over my ground cover, working on taking over my lawn, invading my gardens. What do I do?
You can try Sedge Hammer on a small section of your ground cover – see if it only kills the nut grass and not the ground cover – make sure you do this after it cools off. It’s been very hot here in St. Louis. Here’s what the directions say, “Do not apply Sedge Hammer to desirable plants that have been subject to stress conditions such as
hail damage, flooding, drought, extreme heat or widely fluctuating temperatures, as crop injury may result.”
If nutgras is fairly thin – I use the old fashion method. Use a dandelion digger and get them one-by-one. Worksfor me.
graeme–any success with your sugar blend– if so how much did you mix?

Digging this weed out is far two strenuous, it seems to be spreading seeds all across my garden.The main plants are on my neighbors side of my fence. I”sneezing more than I ever have. How lethal is this weed killer for the nutsedge cotton grass is killing me!
It works, just don’t use it on a hot day. I would also suggest cutting it more often, so that it doesn’t go to seed.
