Kathy Clugston and the team are at Levens Hall in the Lake District for a correspondence edition. Matthew Wilson, James Wong and Christine Walkden are riffling through the GQT postbag and in box to answer questions sent in by listeners. This week, the panellists discuss saving a Crown of Thorns, keeping an ornamental pear tree from overgrowing, and the best fruit trees for a Christmas present. The team are joined by Head Gardener of Levens Hall, Chris Crowder, who shows them the impressive 300-year-old topiary.
