On Saturday I went with Oxfordshire Master Composters to visit the rooftop garden at RISC, in the centre of Reading.  RISC is the Reading International Solidarity Centre, a charity with premises in London St.  On the ground floor is the World Shop and a café, and on the roof is a carefully constructed edible forest garden, full of plants (and trees!) which are edible, medicinal or useful.

See the pictures below and the RISC website.
