Your Letters 2 Report post Posted April 8, 2020 I have a sloped area (caused by height difference between driveway and backyard). I put an edge about 6" away from the bottom of the slope (removed all grass to 4" depth) with intent to keep grass from intruding up into the sloped flower bed; however, soils seems to constantly backfill into the open space. My question was how far should I edge away from the slope in hopes of preventing further migration of the grass. This area will be getting a major overhaul this year.S.B.
