Kathy Clugston and an eager panel of gardening experts are in Wensleydale, North Yorkshire to put an end to the audience's gardening grievances. On the panel this week are garden designer Matthew Wilson, houseplant expert Anne Swithinbank, and curator of RHS Bridgewater Marcus Chilton-Jones.

Later, Matt Biggs travels to Dungeness to meet with head gardener Johnny Bruce, who gives him a tour of late director Derek Jarmon's magnificent garden.
