Kathy Clugston and the panel are in the Chilterns. Matthew Biggs, Pippa Greenwood and Christine Walkden are answering the questions from the green-fingered audience. This week, the panellists tackle queries on battling the woolly aphid and tending the aerial roots of an orchid, and offer suggestions for what to plant in a greenhouse over the winter. Away from the questions, Matt Biggs visits the Roald Dahl museum to chat to Rachel White about some of the horticultural influences behind Dahl's stories.
