Hi You may be interested to know that google operates a news search on any topic you select. About 9 months ago, I typed in "community gardening" in the selection box and I regularly receive info related to this topic from many news sources especially newspapers; a ton of current information. I'm sure you'll be pleased with this free service.
Suggest you try it. Here is the link to sign up: Google News Alerts Jerry Houser Guilderland, NY >From the Desk of G. Houser
