RM43 Weed Preventer
Best heavy duty solution for long term gravel and fence line maintenance.
This is the nuclear option for property maintenance, designed to wipe out everything in its path and keep it that way for a full year. It’s incredibly efficient for driveways and fence lines, but use it with extreme caution—this formula doesn't discriminate between weeds and the plants you actually want to keep.
