At Longmeadow, Monty checks the progress of the potatoes he planted earlier in the year and recommends plants for dry shade under trees. The team travel to Somerset to get water-saving tips from a water scientist, who uses a variety of techniques to save as much water as possible in her own garden, and meet a head gardener, who manages a garden in Dorset dedicated to growing plants for their aromatic properties both in leaf and flower. Nick Bailey gives a masterclass on how to grow summer flowering clematis, and Arit Anderson takes a boat trip to meet a group of people who are planting up the Birmingham canal sides for both wildlife and the wellbeing of city dwellers. And there are a few more hints, tips and stories from viewer’s gardens.
