Perlite is an amorphous volcanic glass derived from obsidian. It is mined, then heated under special conditions to create distinct round, white nodules that resemble Styrofoam balls. Heating unlocks its potential as a soil amendment, since it expands considerably. Perlite is not a type of soil, it’s a soil additive that can also be used as a growing medium.
Perlite itself does not have significant nutrient content, being primarily composed of silicon (Si). However, it helps to create the ideal environment for life to thrive in the soil. It’s important to remember that the ideal soil is comprised of 25% air and 25% water. Perlite creates the conditions for robust root growth, enhances water retention in the root system, and optimizes drainage capabilities.
Perlite can be used as a soil amendment or alone as a medium for hydroponics or for starting cuttings. When used as an amendment, it has high permeability and low water retention and helps prevent soil compaction.

Benefits: Perlite resists soil compaction and encourages aeration, even in limited growing spaces. Interestingly, it has also been used to great effect in plants that thrive in dry settings. It can be helpful for starting seeds toward their germination in the springtime. Perlite is organic and helps lower the environmental impact in sustainable gardening.
