Kathy Clugston and her panel of green-fingered experts answer horticultural questions from Oxfordshire.

Why are my leeks brown inside? Should I cut the wispy stems off my wisteria? Why do I kill over 50% of the plug plants I’ve purchased? The GQT team are back to answer all of these questions and more from Winterbrook, Oxfordshire.

Prepped to solve a series of plant problems are botanist Pippa Greenwood, Head of Science of the University of Oxford Botanic Garden Dr Chris Thorogood, and garden designer Chris Beardshaw.

Alongside the questions, GQT panellist, Pippa Greenwood visits Merlin Brook-Little at at Nicholson’s Nursery to discuss all there is to know about plant screening.
