We have several Community Gardens in my small town. I do not know what the charge per plot is (I am lucky to have my own garden), but there is a very large plot set aside for the food bank.
Our food bank will also pick extra fruit in the fall from those with an abundant crop.
When I have a bumper crop of plums, I take them to the food bank.
I wish food crops would be used as landscaping in parks and low income housing projects. An apple tree is just as attractive as an ornamental plum, but provides much needed nutrition. Blueberry plants can use used in gardens, providing fruit and beautiful red stems in the winter.
