Is it worth using arborist mulch in the garden? Please could you advise on how to maintain large camellias? My wisteria has barely flowered this year, what’s gone wrong?
Peter Gibbs and his team of horticultural experts have packed up their windbreakers and travelled to Raby Castle, Park and Gardens in County Durham for a postbag edition of GQT. While head gardener Tim Marshall leads Peter and the panel around the gardens, they also dig through the GQT inbox to answer your gardening queries. On the panel this week are passionate garden designers Matthew Wilson and Bunny Guinness, and house plant expert Anne Swithinbank.
Later in the programme, the panellists discuss the benefits of encouraging birds into the garden to tackle box blight and other garden pests. They also share useful tips on how to prevent box tree caterpillars from spreading.
