Chris Castro has an obsession - turning the perfectly manicured lawns in his Orlando neighborhood into mini-farms. The amount of interest in Orlando is incredibly surprising," Castro says. Surprising because he's asking Floridians to hand over a good chunk of their precious yards to volunteers who plant gardens full of produce. His program is called Fleet Farming, and it's starting off small, with 10 of these yard farms. Most of them sit smack in the middle of the front yard. Lawns are a thing here. Urban farms? Not so much. But so far, no neighbors have complained. Castro makes sure every garden is meticulously maintained - including homeowner Gary Henderson's. "I just think that the whole idea of lawns, especially in a place like Florida, is absurd," says Henderson, standing amid rows of tomatoes, sweet lettuce, carrots and arugula growing smack in the middle of his front yard. All of Fleet Farming's volunteers only ride bikes, going from garden to garden to harvest the produce. Because the program is bike-powered, Castro keeps the yard gardens within a mile of the local farmers market, where Fleet Farming sells most of the produce. Henderson offers this advice to anyone thinking about replacing their lawn with a garden: "Give it a try ... and once you get to the point where you realize that you can eat your lawn, I think it makes a whole lot of sense." And so do 300 other residents of central Florida. That's how many people are on Fleet Farming's waiting list, ready to eat their lawns instead of having to mow them.
