The number of people renting houses has doubled in the past 10 years. But how do you make a garden when you're faced with blank concrete paving or the prospect of having to move home in just a few months? Luckily we have barrowloads of fantastic advice from Matthew Pottage, Curator of RHS Garden Wisley and long-term renter of a house in southwest London. His new book, 'How to Garden When You Rent' is published today. Hear him discuss some of the tips and tricks he's learned from a decade turning a grey concrete yard into a lush urban jungle, all without lifting a single slab. Including advice on design, planting ...and dealing with landlords. Plus we talk to garden designer Sara Edwards, who created an innovative container garden at last year's RHS Chelsea Flower Show. Using IBCs (intermediate bulk containers, widely used in industry and farming) she created miniature forests, ponds and naturalistic planting, to stunning effect. All without breaking into the ground below.
