Here’s a post-Earth Day challenge for readers who are dedicated to organic gardening: Work with local government agencies to celebrate International Compost Awareness Week, set for May 7–13.

Sponsored by the U.S. Composting Council, it’s the largest environmental education event for composting. Across the United States, Canada and the United Kingdom, composting advocates will be encouraging everyone to compost—whether you’re a do-it-yourself gardener or community-based professional.

Urge your mayor or city council to go green by signing a proclamation that supports composting. A sample is available for regional use and modification.
