Gardeners' World : Season 46 Episode 16

With high summer in full swing at Longmeadow, Monty Don is busy ensuring that his plants are making the most of the warmth and light. He puts to use the homemade fertilizer he made a few weeks ago and catches up with his tomato-growing trial to see how the different techniques are performing. Carol Klein gets to grips with flowering dogwoods, perhaps the most aristocratic and elegant of all garden trees, and there's a visit to a magical topiary garden in Kent.
