How to Use Horticultural Pumice:
For most succulents and cacti, we recommend a mix of 60% pumice, 40% organic potting soil. For specialized Bonsai training, we recommend 33% pumice, 33% Organic soil, 33% Akadama for maximum drainage and root control. You can view our other cactus supplies and plants here on our main shop page. This product is officially OMRI Listed for use in certified organic operations, ensuring the highest safety standards for your food and hobby plants. Because it is a natural volcanic glass, it provides a grit that discourages soil pests while maintaining a neutral pH for your delicate root systems.
