Adam Frost adds tall plants for shady conditions to his borders, shows us how to make a window box for growing vegetables and herbs, and gives his tips on how to grow plants successfully in peat-free compost. Nick Bailey is in Worcestershire exploring a garden where peonies are taking centre stage, and we return to the urban garden of Kate Bradbury to find out how she ensures that visiting wildlife is kept well fed throughout the summer months. We travel to the Isle of Man to a garden where a range of exotic plants are thriving in the micro-climate on the island, and we meet a nurseryman in Kent with a passion for hydrangeas.
