Pinchbeck: Awkward Astrantias, Watering Wisdom and Courgette Chaos

Peter Gibbs and the Gardeners’ Question Time panel visit the Lincolnshire village of Pinchbeck, a fenland landscape shaped by waterways and a long history of horticulture.

On the panel are plantswoman Christine Walkden and garden designers Matthew Wilson and Bunny Guinness.

The team tackles questions on choosing pond plants to support dragonflies, finding colourful plants for exposed, windy gardens, and why some gardeners struggle to grow much-loved astrantias. They also offer practical advice on improving courgette crops, planting around hydrangeas, and dealing with troublesome vine weevil.

Water is a recurring theme throughout the programme. Bethan Collerton visits Winterbourne House and Garden to meet plant scientist Professor Jeremy Pritchard and uncover the remarkable ways plants depend on water, from photosynthesis and cooling to the internal hydraulic systems that keep them upright and growing.

Back in Pinchbeck, the panel turns to a question many gardeners face during a heatwave - how often should we water our gardens? Christine shares her advice on watering deeply and effectively to help plants withstand dry conditions.
