Dig into the Bronx’s cultural soil (and its literal soil) in a five-hour trolley tour that will have participants gardening and taking tips from city growers. The trolley makes stops at local grasslands and green estates, like the Tremont Community Garden and the Garden of Happiness, where attendees will learn about the benefits of urban community farms. Reservations are required; call or e-mail email@example.com. Meet at 810 Seventh Ave at 52nd St (718-590-3518). Subway: D, E to Seventh Ave.
