Eric Robson and his panel pay a visit to the Gower Peninsula. Christine Walkden, Bob Flowerdew and Anne Swithinbank answer this week's questions from the audience. The panellists discuss grow lights, good climbers for pergolas and Magnolia stellata propagation. They also suggest ways to eradicate wild garlic, offer advice for mossy lawns, and suggest ways to get a Rosa banksiae ‘Alba Plena’ to flower. Away from the questions, Matt Biggs is at Kew, in the Marianne North gallery, speaking to the galleries and exhibition leader Maria Devaney about Marianne North, the botanical artist.
