The children at Buena Vista Horace Mann School in the Mission District of San Francisco have planter boxes around the entire block of the school. One side, a busy street is primarily water conserving plants and flowers. That side also has a mini-park that takes up two former street parking spaces that is a demonstration of how plants gain water, issues in water use and conservation, and what rain is all about. On the residential side, new planter boxes (about 8 boxes) have just gone in to provide free food for the taking, once the plants start producing. A great idea in helping children understand how food grows, but also providing the bounty to the neighborhood. Street salad…what a wonderful idea.
