What is perlite and should I use it with my houseplants?

Perlite is a type of volcanic glass that is often used in gardening and horticulture. It is lightweight, sterile, and has a high water-holding capacity, which makes it an ideal growing medium for plants.

Perlite has several benefits for plants. Firstly, it provides excellent drainage and aeration, which helps to prevent waterlogging and allows roots to grow freely. This makes it a good choice for plants that require well-draining soil, such as succulents and cacti.

Secondly, perlite can help to improve the overall structure of the soil. When mixed with other growing mediums, it helps to increase the soil's porosity and water-holding capacity. This can be especially beneficial for plants that require a lot of water, such as tomatoes and peppers.

Thirdly, perlite is a sterile growing medium, which means that it does not contain any harmful bacteria or fungi that could potentially harm your plants. This can help to prevent the spread of diseases and pests, and can help your plants to grow more healthily and vigorously.

Overall, perlite is a useful and beneficial addition to any garden or plant collection. It can help to improve the overall health and growth of your plants, and can make your gardening experience more enjoyable and successful.
