You could try volunteering at the Dulwich Vegetable Garden (DVG) behind Rosebery Lodge in Dulwich Park. We're always looking for more people. It's a volunteer-run community fruit and veg garden, and everyone shares the produce. During the winter the DVG is open Sundays only, 10.30-12.30. From 1 March it will be open on Wednesdays as well at the same time. Christine Dulwich Veg Garden
