Pebbles Next to Lawn: Dangerous Without a Physical Barrier

Question: Remove mulch/bushes/weeds beside lawn, lay weed mat + 20mm pebbles. Will pebbles at lawn height make mowing hard? Need retaining wall? Level or raised?

Answer: Pebbles + Mower = Projectile Hazard—Install a Barrier

Mower blades throw pebbles—very dangerous. Need physical barrier: wide curb (min 150mm) or low retaining wall (rubber, wood, concrete, block, brick) to catch mower wheel and keep blade off pebbles.

Examples: blockwork, lawn edging, search lawn edging, edgn.
