Light, porous, and fantastic for boosting airflow, coarse pumice is a dream for chunky soil blends. It holds onto just enough moisture without becoming waterlogged, helping roots stay oxygenated and healthy. Perfect for cacti, succulents, and aroids, it’s a brilliant way to increase drainage and reduce compaction in any mix. Unlike perlite, pumice won’t float or break down, making it a long-lasting addition to your plant care arsenal.
