Buying Guide
- Intent matters: Use lava rocks for drainage and mineral benefits in pots; use river rocks for large color accents and ground cover.
- Size and density: Smaller stones (1/2″ to 1″) are better for planters; larger pebbles (2-3″) work well for pathways and displays.
- Color stability: Choose naturally colored stones to avoid fading; natural red tones typically resist color loss.
- Applications: Lava rocks excel in drainage and heat resistance; river rocks excel in visual impact and moisture retention.
- Maintenance: Some natural stones have surface irregularities; rinse before use and occasional cleaning helps maintain color and luster.
- Safety and suitability: Check whether stones are suitable for aquarium or edible garden areas if relevant; avoid dyed or chemically treated stones for sensitive uses.
