In the last of this year's series of Gardeners' World, Monty has plenty of advice on the jobs we can be doing now and over the winter in the garden. He also reviews some of the plants which have thrived and those which have not during this extraordinary summer. On Walney Island in Cumbria, Carol explores the diversity of wild plants which thrive in its maritime climate and discovers a very special hardy geranium which grows nowhere else in the world. Rachel travels to Swansea to meet passionate gardener Andrea Gordon, who, despite being blind from birth, has a garden overflowing with plants. And Joe meets 92-year-old Walter Partridge who not only produces an abundance of vegetables on his immaculate allotment in Grantham but is also the bee-keeper for the site.
