Joey from Durham, Nc writes
Trying to control weeds on forest ground. Would like to keep them down all year via one application without killing the established pine and oak trees. Think these two will handle it, can they mix and at what rate?
Gly Pho-Sel Pro is going to kill or affect any plants that you spray with it, while the Surflan is a pre-emergent that is safe to use around established trees. So if you are mixing these two, then you would still have to spot treat the existing weeds very carefully so that you do not spray any leaves, stems, roots, etc. of desirable plants. This could then result in spotty pre-emergent control from the Surflan since you would not be able to apply it over much of the area. Since the Gly Pho-Sel Pro is non-selective, we would not recommend mixing these products in an area that includes desirable plants.
