Kathy Clugston is joined by a panel of experts to answer gardening questions in front of a virtual audience. Bob Flowerdew, Bunny Guinness and Pippa Greenwood are on the panel. This week, the panellists answer questions on how to choose the right mulch, recommend palm trees for a south-easterly facing garden and compare techniques on saving an un-cheery cherry tree. Away from the questions, Peter Gibbs is at Wakehurst, Royal Botanic Garden Kew to see their American Prairie project with Ed Ikin, and Juliet Sargent is sharing tips on preparing your garden for winter.
