Stopping Rubber Mulch Washout: Edging Solutions That Work

Rubber mulch in shrub beds is washing down driveways and walkways during rain. Will edging stop it?

Yes—any edging helps. Rubber mulch floats. It's buoyant. Without a barrier, every storm redistributes it.

Edging Options (Best to Good)

1. Commercial-grade aluminum/steel restraint (Oly-Ola, Permaloc) – invisible, permanent, pro standard.
2. Brick or concrete pavers on edge – attractive, DIY-friendly, set in sand bed.
3. Pressure-treated 2×6 or 4×4 timber – cheap, 10–15 yr life, stake every 3 ft.
4. Rolled plastic/metal coil edging – low cost, less durable, stakes pull out.

Design Tip

Set edging ½" above mulch grade. Creates a true lip. Mulch stays put; mower wheels ride over cleanly.
