BIOMAND River Rocks 18 lb Mixed 1–3" Polished Pebbles for Plants — Drainage & Low-Maintenance

BIOMAND 18lb Mixed River Rocks are natural 1–3" polished pebbles that decorate pots, improve drainage, and reduce weed growth for indoor and outdoor plant displays.

These hand-selected river stones combine durability and a smooth finish to give planters, terrariums, pathways, and water features a long-lasting, low-maintenance top layer. Unlike wood mulches that break down and lose color, these stones keep their natural tones while letting water flow through. The mixed color palette fits rustic and modern schemes, and the heavier weight helps keep soil and decorative layers in place against wind, pets, and light foot traffic.

How do these river rocks help my potted plants?

Using BIOMAND pebbles on the soil surface reduces evaporation, stabilizes potting mix, and prevents soil splash during watering. Their rounded shapes protect roots while allowing air and water to pass, so pots drain cleanly and look finished.

• Maintains moisture balance by reducing surface evaporation.
• Prevents soil washout when watering or during heavy rain.
• Protects delicate roots from compaction and exposure.
• Adds an attractive, polished finish to any planter.

Can I use these stones outdoors around the yard or in ponds?

Yes—these river rocks are suitable for outdoor landscaping, garden borders, pathways, and water features. Their smooth, water-polished surfaces make them ideal for drainable, decorative beds and accents that won’t fade or decompose season after season.

• Heavy 18lb bag covers larger areas and stays put in wind and rain.
• Works well in dry creek beds, around fountains, and as pond edging.
• Resists fading and breakdown unlike organic mulches.
• Helps create clear, mud-free walking surfaces after rainfall.

Which color option should I choose for my design scheme?

BIOMAND stones come in mixed tones plus options like sleek black or bright white—choose based on contrast, reflection, and the mood you want to build. Mixed stones add an organic, rustic look; black creates a modern, minimalist backdrop; white brightens and emphasizes plants and lighting.

• Mixed: natural, varied tones for informal and cottage-style setups.
• Black: contemporary, high-contrast look that highlights foliage.
• White: reflective and crisp, ideal for brightening dark corners.
• All maintain color over time without breaking down like wood mulch.

How much coverage will a single 18lb bag provide and how do I apply it?

Coverage depends on the layer depth and pot or bed size; an 18lb bag typically covers several medium pots or a modest garden border when spread 1–2 inches deep. Apply after planting: smooth a uniform layer over the soil, leaving a small gap near stems to avoid moisture buildup against trunks or crowns.

• Recommended depth: 1–2 inches for drainage and weed suppression.
• Spread evenly and gently tamp to settle stones into place.
• Leave 0.5–1" clearance from plant stems to prevent rot risk.
• Combine with landscape fabric for extra weed control in beds.

If you want a tidy, low-maintenance top layer that lasts seasons, resists fading, and improves drainage while enhancing visual appeal, these polished 1–3" stones are a practical, decorative choice.
