Peter Gibbs hosts the second of two specials from the annual GQT Summer Garden Party. Matt Biggs, Pippa Greenwood, James Wong and Anne Swithinbank answer horticultural questions from the audience at National Trust Mount Stewart in County Down, Northern Ireland. This week the panellists are quizzed about a mysterious fungal growth on a plum tree, pruning herbaceous geraniums and encouraging a Clivia to flower. They also offer suggestions for a windy balcony and a ruby plant to celebrate a ruby wedding anniversary, alongside some advice for gardening in damp soil. Away from the questions, Neil Porteous takes Matthew Pottage around the Italian Garden at Mount Stewart to find out about it's mythical inspiration.
