Our Process
From waste to wonder in five carefully controlled steps.
Sourcing
We collect organic waste from local farms and food processors — material that would otherwise end up in landfills. Every bag of SuperPoop diverts waste from the trash.
Feeding
Our red wiggler worms are fed a carefully balanced diet of organic matter. The composition of their food directly affects the quality of the castings, so we monitor it closely.
Digestion
Inside each worm, billions of beneficial microorganisms break down the organic matter, creating a nutrient-rich material packed with enzymes, humic acids, and plant growth hormones.
Harvesting
We carefully harvest the castings using a process that separates the finished product from the active composting material, ensuring consistent quality in every bag.
Testing & Packaging
Every batch is tested for nutrient content, pH levels, and microbial activity. Only batches that meet our standards make it into a SuperPoop bag and onto your garden.

Frequently Asked Questions
Everything you want to know about worm castings.
Worm castings are the end product of the breakdown of organic matter by earthworms. In simpler terms, it's worm poop! But don't let that put you off — it's odorless, looks like rich dark soil, and is absolutely packed with nutrients and beneficial microorganisms that plants love.
Yes! Worm castings contain a balanced mix of nitrogen, phosphorus, potassium, and essential micronutrients in a form that plants can immediately absorb. Unlike synthetic fertilizers, they won't burn your plants, they improve soil structure, and they introduce beneficial microbes that protect against disease.
Absolutely. Worm castings are gentle enough for the most delicate seedlings yet powerful enough for heavy-feeding vegetables. Use them on houseplants, flowers, vegetables, herbs, lawns, trees, and shrubs. They're safe for organic gardening and won't harm pets or children.
For best results, top-dress your plants with worm castings every 4-6 weeks during the growing season. For new plantings, mix castings directly into the soil. You can't over-apply worm castings — they're that gentle.
Not at all! Despite being worm poop, quality worm castings have a pleasant, earthy smell — like walking through a forest after rain. They're perfectly fine to use indoors with houseplants.
Yes. Our worms are fed a carefully controlled diet of organic matter, and we add nothing artificial to our products. Our Pure Worm Castings are OMRI Listed, meaning they've been independently verified for use in organic production.
Store in a cool, dry place out of direct sunlight. Keep the bag loosely closed — worm castings contain living microorganisms that need some air. Properly stored, they'll stay effective for 6-12 months.
