From The Chicago Tribune: More than 40 Chicago public schools have created gardens that grow fruits, vegetables, herbs and flowers. But none of what’s grown ever finds its way into school lunchrooms because of rules set by the district and its meal provider. To use the items in the school food program, it would need to meet specific growing practices, the district says, such as eliminating all pesticides and insecticide applications and using only commercially prepared organic compost and fertilizers. Commercial vendors, though, don't have to abide by these rules.
