How to stabilize a large landscape stone
Heavy landscape stones like millstones often sink into garden areas over time, creating a constant worry. Stabilizing them is difficult because you cannot simply lean them against a house, as micromovements will grind the stone into the brick. Solving the problem is further complicated by the massive challenge of simply moving the stone in the first place.
