Pumice 1-7mm is horticultural pumice for growers who need a clean, mineral-based amendment for potting mixes, cactus blends, succulent media and indoor plant soil. Its small 1-7mm particle size makes it useful where extra drainage, structure and air space are needed in the root zone.
Use it in custom growing media, propagation mixes, bonsai blends, aroid mixes and container gardening setups where standard potting soil needs a more open, free-draining texture.

How to use it
Mix Pumice 1-7mm through your chosen potting media at a rate suited to the plant and growing style. For plants that prefer fast drainage, use it as part of a gritty mix with other suitable components. For general potting mixes, blend in smaller amounts to improve texture and airflow.
You can also use pumice as a surface top dressing for suitable pots, or as part of a mineral-heavy mix for plants that dislike dense, wet soil. Watering frequency may change once pumice is added, so monitor how quickly the mix dries in your conditions.
Check before buying

- Some moisture-loving plants may not need a highly free-draining mix.
- Use with other appropriate media components if building a complete potting mix.
