Outdoor Decorative Stones

Pick stones based on function and scale: smaller pebbles (1/8"–1/2") are good for pathways and mulching, medium gravel (1/2"–1") suits borders and drainage, and larger river rocks or boulders create focal points or retain soil; consider color and texture to match your plants and hardscape

Typical materials include natural river rock, crushed granite, lava rock, slate chips, and polished pebbles; finishes vary from rough and natural to tumbled or polished, affecting appearance, drainage, and how much they retain heat

Measure the area in square feet and decide on desired depth (commonly 1–3 inches for mulch-style coverage, 3–6 inches for weed suppression or pathways); multiply area by depth to get cubic feet, then divide by 27 to convert to cubic yards for bag or bulk ordering

Ensure proper base preparation: compact soil, install landscape fabric if needed for weed suppression (note it reduces but may not eliminate weeds), provide a slight slope for water runoff, and use edging to keep stones contained

Stones reduce evaporation and can moderate soil temperature but may retain heat in hot climates, potentially stressing heat-sensitive plants; use lighter-colored stones or shallower coverage near heat-sensitive species and allow adequate irrigation

Periodic tasks include removing debris, raking to refresh appearance, replenishing settled or dispersed stones every 1–3 years, and addressing weeds that penetrate fabric with spot treatments or hand-pulling

Decorative stones commonly fall into budget options under $50 for small bags and bulk/landscape deliveries for larger projects; cost varies by material, finish, size, and whether items are sold by bag or cubic yard, with average product prices in this category around $70
