I have battled wild violets for the last few years without much success. I have used every product from Lowes and Home Depot as well as Trimec and Speedzone. I was advised to use the Speedzone in the fall for a better kill, which I did. Now I have new blooms coming up(only a few thankfully). Do you have any suggestions of what I can use to stop the spread? I know I won't kill them all, but I am hoping a proactive approach this year will do some serious damage. I called Lesco but the only product they recommend(forgot the name already) is over 100 bucks and is a HUGE bottle. I cannot have the area sprayed by a company because I live in a water supply protected area. I have to do it myself.
