For this week’s show, we’re delving into the natural world of cities – looking at how best to grow our favourite plants with limited space and to treasure the diverse flora and fauna of our cityscapes. Author Ben Dark shares his love for the wisteria embellishing urban front gardens. Urban farmer Alessandro Vitale – you might know him as Spicy Moustache — takes us through all his tips and tricks for growing vertically in whatever space you’ve got. And, author and amateur urban naturalist, Bob Gilbert, gives his thoughts on the sounds of London’s trees. But that’s not all – we’re ending the show with a touching tribute from Daisy Payne on what she’s doing in honour of Celebration Day on 28 May.
