Here in the Garden with Ron Wilson, Ron chats with Dr. Greg Wanger, the founder and chief technology officer of Oberland Agriscience. They dive into the world of insect frass, a natural fertilizer made from the waste of black soldier flies. Dr. Wanger shares the process of turning food scraps into a valuable resource, and how it’s being used to create a more sustainable gardening practice. They discuss the benefits of this eco-friendly fertilizer, its availability, and how it’s being marketed to gardeners.
