Slope Planting & Terracing for Dry Southern California Hillsides

On a steep .45-acre Riverside County slope with three pines, replace ice plant with erosion-control plants: Liriope muscari (variegated or solid, white/purple flowers), ornamental grasses (deep roots), and Cotoneaster (spreading, berries). Terrace the slope with natural stone steps for access and planting pockets—level areas hold water, reduce runoff, and let you diversify plantings.

Hydrozone: group plants by water needs. Use drip irrigation on timers. Mulch heavily. Avoid tilling on slopes—plant in individual holes with soil basins. This approach stabilizes soil, reduces maintenance, and creates a walkable, beautiful hillside.
