What is perlite?

Perlite is a volcanic mineral that is widely used as a soil conditioner for houseplants. It is a lightweight, white, and porous material that is made by heating volcanic glass at high temperatures. Perlite is an excellent addition to your houseplant soil because it improves drainage, aeration, and water retention.

Many potting soils contain perlite. You see perlite as small white balls in your potting soil. So no, that is not isomo!

When buying perlite, it is essential to choose a product that is pure and free of dust or debris. It is also essential to choose the right type of perlite for your houseplants. There is coarse perlite, which is best for cacti and succulents, and fine perlite, which is ideal for ferns and other plants that like moist soil.

Benefits of perlite

One of the most important benefits of using perlite in your houseplant soil is that it improves drainage. When perlite is mixed with other soil components, it creates small air pockets that help drain excess water away from your plants’ roots. This prevents root rot and other water-related problems that can damage or kill your plants.

Perlite also improves aeration, which is essential for healthy plant growth. The tiny air pockets created by perlite allow the roots to access the oxygen they need to thrive. This is especially important for container-grown houseplants, as these plants can struggle to get oxygen in compacted soil.

Another benefit of perlite is that it holds water in the soil. While it is essential for houseplants to have well-draining soil, it is also important that they have a consistent water supply. Perlite is a hydrophobic material, meaning that it repels water. However, it can also hold water and slowly release it over time. How much water? Up to 4 times its weight! This helps keep the soil evenly moist and eliminates the need for frequent watering.

When purchasing perlite, make sure you choose a pure, dust-free product, and the right type of perlite for your houseplants. With a little research, you can find the perfect perlite to help your plants thrive.
