Pressed for Time: My Empire of Dirt

May 13, Greenlight Bookstore, 686 Fulton St. (at S. Portland Ave.), Brooklyn, 718-246-0200; 7:30, Free. All the urban farmers would do well to attend the reading of [Manny Howard’s new book]. Howard lives in Flatbush, had an 800-square-foot yard, built a farm and then lived off the food he grew therein. And now his book has come out. Me? I grow mint in a tiny planter in my backyard. Bottom Line: Learn the cost, the glory and the nitty-gritty of urban farming.
