We too have a "church garden." To date, we have donated over 100 lbs of fresh veggies to our local interfaith ministry which feeds the poor. We have also planted about 7 blueberry bushes for future picking. I would like to know more about gleaning and how to share this with the poor.
What an exciting ministry that your church is undertaking! You can sign up to be a "Let's Move" congregation at www.pcusa.org/letsmove to help meet the goal of getting 1,000 Presbyterian Churches involved in ending childhood obesity through projects like neighborhood gardens. Also, we'd love to have someone from your church join the Environmental Ministries Action Network if anyone is interested. Both programs will offer resources and ideas to churches working on projects like yours.
We have just this summer begun a 'neighborhood garden', starting with 2 raised beds on our church property. This is a new venture for us, but the garden is thriving.
