As the plants in the jewel garden reach the peak of their late summer glory, Monty Don starts planning for the spring by planting ferns and offering advice on the care and maintenance of wildlife ponds. Carol Klein pays a second visit to Dove Cottage in West Yorkshire to see the garden at its summer peak, while Frances Tophill travels to Portsmouth to find a man whose passion for ferns has spilled out from his garden and onto his allotment. Plus, Arit Anderson finds out that even rubbish skips can be used to grow all manner of plants in an inner city space.
