Adam Frost is in his garden, bringing viewers up to date on how it has been developing over the summer, as well as giving plenty of advice on looking after and growing hydrangeas. In Devon, Toby Buckland shares his tips on dealing with damaged shrubs, tree pruning and transplanting perennials, while Frances Tophill travels to West Sussex to meet a gardener and professor of biology whose garden has been planted with the conservation of insects in mind. There is a second chance to see Carol Klein’s in-depth profile of a national collection of hydrangeas at Darley Park in Derby, and a couple of years ago, the team met Charles Dowding, whose unique method of growing vegetables results in bumper crops.
