I searched everywhere and bought your product to kill grasses growing in my iris beds. It didn't do anything g to kill the grass

This is the only product I have found that kills grasses that try to take over my iris and asparagus beds that doesn't affect the iris and asparagus. It does take patience as you won't notice the grass dying right away, especially in cooler weather with lows in upper 30's and daytime highs in the mid sixties. I sprayed initially 4 weeks ago with a second application a week later using dormant oil in the mixture. This is the first week that I can see more brown grass than green and it is definitely working on those hard to kill grasses that send runners all over.

Hi-Yield Grass Killer has done an excellent job of killing the common bermuda in my centipede lawn. It took about two weeks to be totally noticeable, but it is certainly noticeable now. I regret that I waited so long in the summer to apply it. Plan to hit it hard next spring to try and totally eliminate it. I'm sure it has killed some othe unwanted weeds, but I mainly bought it for the common bermuda. This was done through spot treating.

If I could give a no star I would. Product didn't work. U can't return if open. Product takes up to 2 weeks to kill. I will not ever buy from this company again.

This is the only weed killer I have found, that kills cat-tails effectively. Not cheap, but worth it.

The product seems to be working to selectively kill the Johnson grass out of my wild flower bed. The coreopsis is unharmed. It does take quite a while for it to die, however. It's been about two weeks and I may use a second treatment just to ensure that all the Johnson grass is completely gone.

I had some Bermuda grass growing in the centipede grass, this stuff killed the Bermuda grass without fully killing the centipede grass. The centipede did yellow a little bit and was stunted, but was not killed.
