What can I use to stop mites from destroying my nine foot Schefflera? Why haven't we seen many bees this year? How do I remove fungus growing on my hawthorn tree? Peter Gibbs and his team of gardening gurus travel to Blenheim Palace in Woodstock for a postbag edition of GQT. While Head Gardener Andy Mills leads Peter and the panel around the historic grounds, they also rake through the GQT inbox to answer your gardening queries. On the panel this week are garden designer Chris Beardshaw, house plants expert Anne Swithinbank and pest and disease expert Pippa Greenwood. Later in the programme, the panellists receive a surprise question from English fashion and textile designer Dame Zandra Rhodes, who asks what she should do about her dying hydrangeas.
