Dear Auntie Em, I visited the Emerald City just south of Miami (which gets its jewel-like hue from all the farms and exotic palm trees). Down an unpaved dirt road, I discovered Fresh Gardens, a farm run by Bob Petrucci. This guy’s a wizard with tropical fruits: longans, star fruit, guavas, lychees, mameys, passion fruit, dragon fruit, you name it. He’s part of a national network called From the Farm that lets people purchase directly from farmers (who earn a bigger profit that way). Fresh Gardens is open by appointment for those who want to come out, come out, wherever they are and pick their own fruit. (Tip: bring bug spray.) They also ship anywhere in the country, so if you only had a brain, you’d order mangoes before they’re out of season. Love, Dot P.S. There’s no place like Homestead. Fresh Gardens, 31400 Southwest 194th Avenue, Homestead (305-245-8388 or localharvest.org); online at fromthefarm.com.
