Peter Gibbs and the GQT panel visit the charming village of Harmondsworth, just moments from the bustle of Heathrow.

Peter is joined by James Wong, Frances Tophill and Bunny Guinness as they tackle horticultural conundrums, submitted by an audience of local gardeners. From growing citrus trees from supermarket fruit pips to distinguishing wild geums from their cultivated cousins, the panel share practical advice and horticultural insight.

There’s guidance on reusing compost, choosing hydrangeas for tricky shady spots and selecting the right planting choices to create year-round impact on a patio.

Later in the show, Frances explores the benefits of horticultural therapy with a local practitioner, Hardip Singh Lawana MBE, uncovering how gardening can support wellbeing and bring people together.

And to finish, the panel reveal which weeds they’d be, with answers ranging from charming to mischievous.
