Which herbs put you at ease? Which exotic fruits might it be possible to grow in our gardens in the future? Are there any themed gardens you dream of creating?   The GQT panellists are back in Ditchling to answer these questions and more in front of a live audience. Ready to share their smart solutions to all your plant predicaments are RHS Wisley curator Matthew Pottage, horticultural pathologist Pippa Greenwood, and garden designer Juliet Sargeant.  Alongside the questions, horticulturist and garden designer Cherry Carmen gives us plenty to pond-er with her tutorial on preparing your pond for spring.
