Peter Gibbs hosts the horticultural programme featuring a group of gardening experts - Bob Flowerdew, Matthew Pottage and Bunny Guinness - and a virtual audience of green-fingered listeners. This week, our panel answers your questions on temperamental wisteria, planting around a Wendy house, and what you can plant to encourage pollination in your garden. Away from the questions, Pippa Greenwood visits Rosy Hardy of Hardys Cottage Garden Plants to take a trip down Chelsea memory lane.
