This manual gives growers, gardeners, and worm farmers a clear understanding of how different types of worm castings are created — and how each type uniquely supports plant health. You’ll learn exactly how worm diets, microbial activity, and organic matter transformation determine whether your castings become fungal-dominant, bacterial-dominant, nutrient-enriched, or humic-rich.

Instructor
I’m Samantha, the founder and lead educator behind Mimi’s Worms. I work hands-on with composting worms every day, helping beginners and growers learn how to care for their worms, maintain healthy bins, and turn food scraps into rich, usable compost through vermicomposting.
My experience comes from real-world worm farming, not theory. I’ve worked with Red Wigglers and European Nightcrawlers across different setups, learning what actually works when it comes to feeding, bedding, moisture balance, temperature control, and long-term worm bin maintenance. My goal is to simplify worm composting so anyone can succeed without feeling overwhelmed.
Through Mimi’s Worms, I share step-by-step guides, educational blogs, and practical resources based on firsthand experience. I focus on preventing common beginner mistakes while also helping hobbyists and small-scale worm farmers improve productivity and worm health.
I’m passionate about sustainability, soil health, and making composting approachable and rewarding. Everything I teach is designed to help you build confidence, keep your worms thriving, and create a system that works for your lifestyle.
This manual finally helped me understand worm castings instead of just guessing. It’s simple, easy to follow, and my plants are already looking happier.
