We have guerrilla gardeners here in London, but a group in San Francisco has taken the concept and made it more, well, fruitful.
The Guerrilla Grafters are on a mission to “undo civilisation one branch at a time” by grafting fruit bearing branches onto the non-fruit bearing fruit trees that line their city streets. The ultimate aim is “to turn city streets into food forests”.
The team has created a web app to help the city’s citizens find “graftable” trees, and offer instructions as to how to help the new branch take. The Guerrilla Grafters themselves are keeping tabs on how the grafts are doing; and whether the trees have borne any fruit.
Unfortunately, their website appears to be down at the moment.
