Buying Guide: Drainage Rocks For Succulents
Drainage rocks support root health by preventing soil from staying waterlogged. When choosing, consider size, weight, porosity, and compatibility with your container. Leca clay pebbles offer excellent aeration for hydroponic and soil-based systems, while smaller river rocks can provide decorative layers without interfering with root growth. For terrariums, select lightweight, uniform pebbles to minimize potting complexity. If you plan to use rocks near fish tanks, ensure they are properly cleaned to remove oils and coatings. Finally, note that some polished stones may require washing or surface treatment before use.
Key Purchase Considerations
- Drainage vs. decoration: balance porosity with aesthetic goals.
- Rock size: smaller for shallow pots; larger for visible top layers.
- Material: natural clay pebbles (leca) for aeration; polished river rocks for décor.
- Cleaning needs: some rocks need washing before first use.
- Container compatibility: heavier stones may not suit very small pots.
