Our worm castings supplier has an OMRI (Organic Materials Review Institute) listing as of January 2023. Although they are our sole source of worm castings, we have to apply for our own OMRI listing in order to sell under the Urban Worm brand. As of this writing in March of 2023, we have submitted our application to OMRI and anticipate having our own OMRI-listed castings by May or June of this year.

Until that time, if you need OMRI-listed worm castings, please e-mail admin@urbanwormcompany.com where we can refer you to our supplier for bulk organic castings.
