Hey guys, I need some help here. I have some apartment complexes that are low maintenance. The owner does not mind if I use round up around the buildings to avoid trimming. The problem, as you all know, is that I have to re spray about every 6 weeks. I want to avoid this so I would like to know what you all recommend? I have thought about SaharaDG but I'm a little hesitant to use is due to the possibility of run off. I would like something that will mix well with round up and give about 3-4 months of control. I was thinking of something that works like snapshot only in a liquid. I use snapshot preemergent in beds and have great luck with it. What product will work with round up and do the same job as snapshot? I only want to have to spray this a couple times a year because of the time involved. We have mostly cool season grasses and I'm in the transition zone close to St. louis MO. I am licensed and insured. Thanks in advance for the replies.
