So as we are coming up on our mulch jobs, I got to thinking. Well be moving about 40+yds of mulch next week, probably more as soon as esto's go out, and most have opted to have Pre-Emergent layed down after mulching. Usually we just use Preen w/ fert but since we are a turf company, we have Prodiamine w/ 17% urea on hand, lots of it. Im thinking of switching to prodiamine in those beds with established plants. What is your guys choice of Pre-Em in beds? Also has anyone used a liquid formulation w/ a backpack sprayer? Has that sped up application time?
