Hi, I hope this is the correct forum. I could use ya'lls expert advice. I have a maintenance customer who is a PITA. He has his beds mulched and virtually no ground cover left after a year. I treated the nutgrass with sedgehammer, but am having trouble getting it to die off. It has been 10 days now with only minimal yellowing. I dont know if I added too much soap or what? I sprayed each plant until it started dripping. Also, the system is irrigated, but like I said earlier, the ground cover just isnt staying. I am about to treat the dallis grass. Can you also identify what this grass/weed is for me? It looks like it is on a runner. I have attached a pic of the nutgrass, 10days after treatment (this was a large one, the smaller ones show a bit more yellowing. You can also see the ground cover). and I attached a pic of the runner. Any help would be great. Thanks.
