Raw vermiculite is a natural mineral that expands when heated. It is commonly used for plant growth due to its ability to retain moisture and aerate soil. Additionally, it is often employed in construction for insulation purposes.
Dr. Jane Cooper, a horticulturist with over 20 years of experience, emphasizes the benefits of using raw vermiculite in gardening.

"Modern alternatives exist, and in many cases, they are safer and just as effective," he adds.
