Have a pretty bad season for nutsedge in my Bermuda lawn this year. Tried the Image product that you attach to hose and that didn't kill it. Then got this concentrate for 1 gallon spayer to spot spray direct on nutsedge. Unfortunately 2-3 weeks later after 3 separate applications, that nasty weed is still present. Directions followed closely and also added spreader sticker. This nutsedge is tough. If there are any products out there which work better, I'd like to know. Meantime, I'll keep applying this one.
I sprayed my wild onions two weeks ago but I failed to water it in 2 or 3 days later as it states to do. So the onions are still there, but yesterday I sprayed them again and it will rain tomorrow so I will write another review next week.
