Episode 14

It is the end of the week at the RHS Chelsea Flower Show, and Monty Don and Joe Swift are exploring the 'Chelsea effect' - how the trends seen at Chelsea this year have a big influence on gardening styles of the future. Carol Klein reveals the biggest plant trends from the show, while Toby Buckland shows how big plants can be used to great effect in even the smallest of gardens. The team are joined by special guests Martin Parr, Britain's foremost documentary photographer, who discusses pictures he has taken around the showground, and fashion designer Mary Portas, who talks about her beautiful Cotswold garden, and her passion for growing vegetables.
