Worm Castings

There is a huge difference between Vermicompost and Pure Worm Castings.

Clarification is needed for terminology used with the terms worm castings and vermicompost. The term "vermicompost" is used much like "compost". Most people have no idea of how it is going to perform until they use it. Vermicompost contains worm castings and other organic matter that has been partially or fully composted. Who knows how much pure worm castings are found in vermicompost? The amount of pure worm castings will vary from batch to batch and from one vermicomposting facility to another. Introducing a handful of redworms into a compost pile does not produce a good quality of vermicompost.

Our pure worm Black Castings™ are just that - Pure Worm Castings. There are no variables. Each bag, each month and each year consistently delivers high quality Black Castings.™

Quality in - quality out that is what we are all about.
