Quincan Gravel is a lightweight volcanic stone well suited to a wide range of horticultural uses, particularly where drainage, aeration and long-lasting structure are important.
Its naturally porous, vesicular texture helps create air space within growing media, supporting healthy root development and reducing the risk of waterlogging. This makes it useful as a drainage layer, soil amendment, potting mix component, or top dressing for plants that prefer free-draining conditions.
Available sizes:
-
3-5mm: ideal for finer potting mixes, seedling mixes, bonsai, succulents, cacti and top dressing smaller pots
-
5-10mm: ideal for larger pots, drainage layers, raised beds, orchids, natives and more open free-draining mixes
Available pack sizes: 1L, 2L, 3L, 4L and 5L.
