There's a block in San Francisco that will soon be blossoming with cherries, plums, and pears, but Tara Hui will not say where. That's because she's worried that backlash from city officials or unsympathetic citizens will halt the progress she and her fellow Guerrilla Grafters have made splicing fruit-bearing branches on to city trees.
Grafting trees is as simple as cutting a branch from one kind of tree and sticking it into a notch in another, securing it with sturdy tape and hoping that the new branch thrives. It's as old as the Bible and widely used today in industrial agriculture.
Hui hopes the method will help bring food to under-served parts of the city like her neighborhood, Visitacion Valley, which she says is basically a food desert.
"There's a lot of discussion about what kind of policy we need to get businesses to come to this neighborhood to sell fresh produce or even organic," she says. Over the years she's advocated for bringing fruit trees into the city's urban forestry mix. "If all goes well it might even spawn some kind of cottage industry like canning or jamming," she says.
