Our horticultural perlite is your ideal soil improver, from small gardening projects to bulk growing operations. The natural volcanic rock helps prevent soil compaction, increases absorption and drainage, and accelerates strong rooting. Graded at 2-4mm, this perlite is a perfect free-draining additive to succulent potting mixes, improving drainage and aeration. Its coarse micro-porous texture retains moisture without waterlogging, helping prevent fungal diseases and minimising damage when transplanting plants.
