Peter Gibbs and his panel of experts answer your gardening questions. Joining him this week are Matthew Wilson, Bob Flowerdew and Anne Swithinbank. This week, the panel are tasked with suggesting some herbaceous plants for a beautiful early June display. They discover one listener's natural alternative to laundry detergent, soap nuts, and share some other soap-alternative plants for the garden. Away from the panel, we explore the world of Amelanchiers with Christine Walkden, and Claire Ratinon heads South East to speak with parakeet expert Dr Hazel Jackson to learn more about the UK's only naturalised parrot.
