Episode 27

Monty Don shows how to prune and train the exuberant summer growth of climbing roses and makes the most of the seasonal warmth by planting perennials and sowing annuals for next year's flowers.

Frances Tophill visits a viewer's garden to give advice on how to prune unruly shrubs and Nick Bailey investigates a brand new way of combating Himalayan balsam, one of the UK's most invasive weed species. Stourhead in autumn is a horticultural highlight of the year, and Alan Power gives us a behind-the-scenes tour, while Arit Anderson travels to Yorkshire to find out how scientific research has uncovered the superpowers of plants, and we meet a gardener who has dedicated his allotment to growing his own beer.
