Perlite is a naturally occurring volcanic glass that is heated until it pops like popcorn, creating lightweight, porous white granules. Adding it to your soil mix creates tiny air pockets that prevent compaction, which helps roots breathe and improves drainage so your plants don't sit in soggy soil.

A common ratio is to mix one part perlite to three or four parts potting soil, depending on the specific needs of your plants. If you are growing succulents or cacti that require sharp drainage, you can increase the ratio to one part perlite for every two parts soil.
