Why us?

Our Story

Dirty Worm Composting, a family-owned business nestled in the heart of Orlando, Florida, was born from the vision of founders David and Renee Kirwan. Our journey is a dedicated pursuit of promoting sustainability in home gardening, championing zero waste practices, and fostering a local circular economy. Fueled by a passion to address the pressing issues of massive food waste and the overuse of synthetic fertilizers in our state, we embark on a mission that transcends business—aiming to transform our community's approach to agriculture for a healthier, tastier future.

At the core of our endeavor lies a strong desire to share the power of vermiculture with the world. Our emphasis on sustainable practices underscores the importance of responsible cultivation, where the synergy between nature and agriculture results in not only healthier foods but also a thriving ecosystem.
