Peter Gibbs hosts this week's horticultural panel show. Joining him from their homes to answer gardening questions are Humaira Ikram, James Wong and Matt Biggs. This week, the panellists discuss leggy Alliums, give tips for a Sunflower competition, and reveal their gardening sins. Away from the questions, Pippa Greenwood talks about the Big Butterfly Count and Kirsty Wilson tells us about the Himalayan Lily.
