Vermiculite is a naturally occurring mineral that is used as a soil amendment and growing medium for plants. It is lightweight and porous, and has excellent water-holding properties, which makes it ideal for improving soil structure and drainage.

In gardening, vermiculite is often used as a component in potting mixes, seed starting, and as a top dressing for houseplants. It can also be added to garden beds to help retain moisture and improve soil aeration. Vermiculite is easy to use and is suitable for a wide range of plants, making it a popular choice among gardeners who want to ensure healthy, thriving plants.
