After learning more about the effects of throwing away produce, I’ve become increasingly interested in worm composting. Try though we may, my fiancé and I are guilty of letting lettuce spoil more often than we’d like, and tossing it in the trash only serves as a guilty reminder of the methane gases it will produce.

For others like me, registration starts today for Backyard Learn-to-Compost classes, which are free and held weekly from May through October on Saturday mornings, Sunday afternoons, and Wednesday evenings.

If you’re interested in worm composting or learning how to build a compost pile, there are specialized classes on those topics each month.

The classes are sponsored by the Denver Urban Gardens, Denver Recycles/Solid Waste Management, and the Metro Wastewater Reclamation District. Registration is first-come, first-served, and you can sign up via their Web site (linked above).

Classes are held at the Denver Backyard Composting Demonstration Site in the Gove Community Garden, located at East 13th Avenue and Colorado Boulevard.
