Growing Your Worm Farm?

Demand for worms, worm castings and worm-related products is growing rapidly, thanks to the boom in the organic growing movement, the COVID-related surge in interest in gardening, 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.

How to Use This Resource Page

Use this page like a toolbox. Take what you need.

Leave what you don’t.

Some of you are just exploring. Others are ready to take the plunge. I want to help you reach a situation where you are investing rather than risking your time and money.

In no case should you be putting your financial security at risk on a whim.

Note: While I may financially benefit if you choose some of the paid tools on this page like books, memberships, or product sales, I pledge to NOT lead you into a situation for which I believe you are unprepared.

Buy Bulk Worms At a Discount

8 lbs through 48 lbs+

The COVID-19 pandemic inspired a boom in interest in outdoor activities like gardening and fishing.

As a result, some of North America’s largest worm sellers ran out of stock in mid-2020. Despite prices increasing by 30-40% in some cases, demand continued into 2021 and large online worm sellers suffered long-term outages to help recover their breed stock.

Well I’m glad to say that I have partnered with Meme’s Worms near Valdosta, GA to provide bulk red wigglers and European Nightcrawlers to business-minded worm farmers.

Buy to Resell or Grow Your Own Stock

Some worm customers may only be looking for a few dozen at a time.

Buying in bulk and reselling in smaller quantities can be a very profitable business strategy. For bait worms, European Nightcrawlers are a great choice.

You may also be trying to grow your own vermicomposting operation. If so, buying in bulk can help you leap months forward in terms of vermicomposting ability instead of trying to get your existing worms to reproduce faster.

Which Breed Should You Choose?

Buy bulk Red Wigglers if your only objective is vermicomposting or if your customers want a smaller composting worm.

Buy European Nightcrawlers if you want a dual-purpose composting and bait worm. These will also have much better species purity.

We also have pure adult African Nightcrawlers at an excellent price available on this site!

Read the Manual of On Farm Vermicomposting and Vermiculture


The On Farm Manual of Vermicomposting is an extremely valuable free resource, detailing the various methods of vermicomposting, sources of feedstocks and bedding, efficacy of vermicompost and more.

Full of academic citation, familiarity with this work by Glenn Munroe of the Organic Agriculture Center of Canada is a must!

What’s In the Manual?

The Manual of On Farm Vermicomposting and Vermiculture covers the following topics:

  • The Basics of Working With Worms
  • An Overview of Vermicomposting Systems
  • On Farm Vermiculture
  • The Value of Vermicompost
  • Potential Income Diversification

I consider this to be one of the most valuable free resources for the vermicomposter looking to scale up a hobby-level operation or explore which vermicomposting method is appropriate to your situation.

This handy tool operates much like a financial calculator, telling you:

  • how quickly your worms will reproduce
  • how quickly they will produce worm castings
  • the potential financial value of your worms and worm castings
  • how many worms you can harvest and sustain or even grow your worm population

Before You Use the Urban Worm Calculator…..

This tool should not be the basis for any business decisions you make.
