Monty Don makes a start on turning his vegetable patch into a cottage garden. He also tackles the blanketweed that has taken over his pond, and plants a grapevine to train through a hole in the wall of his new greenhouse. Meanwhile, Carol Klein is at Glebe Cottage in Devon where she reveals a little of the fascinating history of one of our woodland gems, the trillium. And Joe Swift travels to Swansea to explore a wonderful suburban garden with a charm all of its own.
