Peter Gibbs and the panel are in Eastbourne for this week's horticultural programme. Matthew Pottage, Christine Walkden and Ashley Edwards answer the questions. On his way, Peter stops by the chalky cliffs of Beachy Head. He speaks with Tim Squire, Ranger for the Eastern Downs of the National Park, who tells him all about the unique chalk grassland of the area. In Eastbourne, the panellists suggest some low-growing plants for a windy, coastal terrace, as well as what we can plant now that the weather is warmer than ever before. They also discuss how to water the garden in drought conditions. Away from the questions Matthew heads over to Sienna Hosta nursery to speak with Chris Potts, who explains how they keep their hostas slug and snail free.
