Hi Jack,
CRWRC and OSJ have teamed up the last few years to offer a congregational grant (Green Grant) to churches who are doing interesting things with creation stewardship. We get a lot of responses from churches who do community gardens - several of theeir project ideas can be found on the grant application website: http://www.crcna.org/pages/osj_greengrant.cfm.
I might have more info on a specific church if you want to know more, otherwise feel free to contact them directly! It'd be cool to have a mentorship model if you're just getting started.

I would like to hear from churches that have successfully implemented a Community Garden. How does it work, how much work is it, etc. Thx!
