Just a quick post to recommend a good book - this is a slight volume, one I picked up secondhand in an Oxfam shop (but you can find it on Amazon too). It's a sensitively written and lyrical book, as much a love letter to the city of London as it is to the Helen Babbs's rooftop garden. The author delights at growing runner beans, tomatoes and strawberries in between bird and bat watching, visits to city farms and strolls on Hampstead Heath. It's a book to make you dream of greener cities, where every rooftop hosts a garden, every window has a windowbox and balconies are crammed with an abundance of greenery. Wouldn't that be something?
