Sukh Horticultural Pumice Stone – 900g for Bonsai, Succulents, and Orchids | Soil Amendment

Overview

Sukh Horticultural Pumice Stone arrives in a ready-to-use 900 g pack. The 5–10 mm particles are light, porous, and pale gray, sourced as an inert volcanic rock. When added to potting mixes, these granules create open structure that helps air circulate around roots while reducing compacting over time. The texture is gritty yet manageable, offering a tactile reminder of its mineral origin as you pot up plants.

Designed for versatility, this pumice works with a range of popular houseplants, from compact bonsai to sun-loving succulents and delicate orchids. It is inert by nature, meaning it won’t leach nutrients or break down quickly, helping you maintain a stable soil profile through growing cycles.
