Taming Landscape Erosion: Mulch, Plants, and Terracing

Heavy rains can turn slopes into erosion nightmares. Any slope dropping more than 12 inches over 10 feet is prone to washing. Solutions include mulch, vegetation, and terracing.

Mulch Options

Pine straw and bark chips are affordable and attractive but can float away on steep slopes. Cypress mulch is heavier but not immune. Free mulch is often available from municipal compost sites or tree companies.

Plants That Hold Soil

Aggressive spreaders like ajuga, spreading liriope (Liriope spicata), creeping raspberry, and English ivy anchor slopes effectively. Improve soil before planting—plants cannot establish in compacted clay.

Terracing with Timbers or Stone

Break long slopes into steps using landscape timbers or stone. Anchor timbers with ½-inch rebar driven 24 inches deep.

Legal Note on Water Diversion

Georgia follows Civil Law doctrine: landowners must accept natural water flow from neighboring property. Building a berm to divert water onto a neighbor's land may be illegal. Resolve disputes through conversation, small claims court, or legal counsel.

Choose the method that fits your slope, budget, and aesthetic.
