Perlite is a type of volcanic glass that is commonly used in nurseries for various horticultural purposes. It is a lightweight, porous material that has excellent water retention and drainage properties. These properties make it an excellent medium for growing plants.

One of the primary uses of perlite in nurseries is as a soil conditioner. When mixed with soil, it can help to improve soil structure and water retention. Perlite can also be used as a standalone growing medium for rooting cuttings or starting seeds. The porous structure of perlite provides excellent aeration to the root zone, which promotes healthy root growth.

Another use of perlite in nurseries is to improve soil drainage. Soil that is too dense or compacted can lead to poor plant growth and root rot. Adding perlite to soil helps to loosen it up and create air pockets that allow excess water to drain away. This improves soil aeration and reduces the risk of root rot.

Perlite is also used in hydroponic gardening, where plants are grown in a nutrient solution instead of soil. Because perlite has a neutral pH and lacks nutrients, it is an ideal medium for customizing plant nutrient solutions. It is also reusable, making it an eco-friendly option for hydroponic gardening.
