Might our otherwise polluted River Thames have a positive impact on my garden? Why has there been so much whitefly this year? Do the panel have a favourite garden they鈥檝e visited?
Peter Gibbs and a panel of green-fingered gurus head to the Phyllis Court Club in Henley-on-Thames, where a lively audience of passionate gardeners awaits answers to their most pressing plant problems.
Joining Peter are pest and disease specialist Pippa Greenwood, head gardener Matthew Pottage, and the ever-enthusiastic plantswoman Christine Walkden.
Later, Johnny 鈥楬ot Stuff鈥� Mayard discusses how he grows chillies in his polytunnel that are used for his hot sauce.
