Kathy Clugston and her panel of gardening experts are in Preston. Christine Walkden, James Wong and Kirsty Wilson field the questoins. The panellists are at the University of Central Lancashire this week, where Kathy speaks to Vice Chancellor Graham Baldwin and groundsman Dave Genther about the new roof garden they've planted there, to encourage pollinators and support student wellbeing. Down in the hall, the panellists tell us how to grow cauliflower and beetroot in the shorter growing season up north. They also advise on how to get lots of flax seed on a budget, and explain how to keep auriculas alive over winter. Away from the questions, Matthew Wilson heads to Kew Gardens and speaks to botanist Carlos Magdalena about the new waterlily they’ve discovered there - Victoria Boliviana.
