Horticultural pumice is a solidified foam that is formed from lava. It is an inorganic material that is odourless, does not break down, decompose, rot, and does not attract bugs. It is very porous and rough in texture making it a great material to use when growing cacti and succulents!


- Greatly improves airflow through the substrate
- Increases water retention in sandy substrates
- Pores help store needed nutrients from watering
- Helps prevent soil compaction so that moisture can be distributed evenly throughout the soil
- Provides plenty of grit which helps to promote strong root development

Recommended Use

- Best when added to cacti or succulent substrates for optimal moisture retention and drainage
- Add to sandy substrates to improve water retention
