Diversify your home-grown meals by swapping your own backyard produce for that of others. Urban-gardening nonprofit Phat Beets Produce hosts crop swaps the first Saturday of every month - including Saturday, April 2 - at the North Oakland Farmers' Market (57th and Market streets, Oakland). Participants are urged to bring home-grown fruits, vegetables, plants, cuttings, or cultures to swap or barter. 10 a.m., free (RSVP to firstname.lastname@example.org; outline what you'll bring).
