Want to Start a Commercial Worm Farm Business or Vermicomposting Operation?
Growing Your Worm Farm?
Demand for worm castings and worm-related products is growing rapidly, thanks to the boom in the organic growing movement and legalization of cannabis in an increasing number of US states.
The motivation to recycle organic waste and live a Zero Waste lifestyle is also a driving factor behind the resurgence in interest in vermicomposting coupled with composting to provide a valuable organic fertilizer.
What Is Your Worm Farming Objective?
Everyone's ideas and constraints are a little different. And those differences significantly effect how you plan to scale your operation.
While worm farming, aka vermiculture, is generally understood as the raising of earthworms for profit, it is often used interchangeably with vermicomposting, the practice of using earthworms to recycle organic waste into a valuable soil amendment.
Your objective may be one or more of the following:
- Building a for-profit worm castings business
- Growing worms for the bait industry
- Installing a vermicomposting program at your school or university
- Recycling your farm's organic waste
- Manufacturing goods or equipment
If this describes your situation, you will find something useful on this page.

- the potential financial value of your worms and worm castings
- how many worms you can harvest and sustain or even grow your worm population
