Which colourful plants thrive in shady, chalky soil? How can I reach into borders without treading on emerging plants? Can leaving weeds help veg crops? The GQT panel answers all.

Peter Gibbs and the GQT team are in Chaldon.

Peter's joined by Anne Swithinbank, Pippa Greenwood and Matthew Pottage.

This week the panel take on a wide range of gardening dilemmas, from how to reach into borders without treading on emerging plants, to which colourful plants thrive in shady, chalky soil. When it comes to growing veg, the team also has answers on whether leaving weeds in place can help crops during extreme heat, and tips on non鈥慶hemical approaches to protecting cabbages and sprouts from hungry pests.

The panellists also discuss how their plant recommendations have changed over the years, and which plants they now avoid altogether!

Later in the show, we hear from Peter鈥檚 visit to RHS Wisley where he spoke with RHS Chief Horticultural Advisor, Guy Barter, and Botanist and Taxonomist, Dr K谩lm谩n K枚nyves to follow up on last year鈥檚 Daffodil diaries scheme.
