Anyone have experience with Gallery or Eptam pre-m's in shrub beds? Thinking about switching to Gallery for spring application (Dimension + something else in late summer/fall), expensive yes but my high end customers won't balk if I charge a little extra if it's a better material. And...a customer asked me to apply some Eptam for them that they had sitting in the garage. I've never paid much attention to it before but it is labeled for purple nutsedge contol which would be VERY nice if it works well. Unfortunately the label recommends incorparating to a depth of 6 inches which typically isn't helpful in my situations. Anyone used this before?
