Chelsea Flower Show 2026 - Postbag
Kathy Clugston and Peter Gibbs are at the Chelsea Flower Show for a postbag episode of Gardeners' Question Time with Bethan Collerton, Matthew Wilson and Pippa Greenwood.
Kathy Clugston and Peter Gibbs are at the Chelsea Flower Show for a special postbag episode of Gardeners' Question Time.
From the showground of the world鈥檚 most celebrated horticultural event, they're joined by a stellar panel - former Chelsea exhibitor and medal-winning designer Matthew Wilson, one of the world's leading authorities on plant pests and diseases, Pippa Greenwood, and making her press-day debut at Chelsea with GQT, Head Gardener at Birmingham Botanical Gardens, Bethan Collerton.
As Kathy and the panel roam the show gardens answering questions submitted by listeners, they catch up with several garden designers behind this year鈥檚 show, including Frances Tophill (The RHS and The King鈥檚 Foundation Curious Garden), Sarah Fisher and Janice Molyneux (The Sightsavers Garden) and Patrick Clarke (The Children鈥檚 Society Garden). They explore the ideas, craftsmanship and planting inspiration behind their Chelsea creations, from sensory container gardens to spaces designed for well-being and connection.
Meanwhile, Peter takes the roving reporter mic inside the Great Pavilion, discovering the science behind our gardens, speaking to exhibitors, and uncovering the latest innovations in horticulture and biodiversity research.
The panel tackles everything from gardening in challenging coastal conditions, to choosing the right trees for privacy and produce, as well as tips on drying flowers for wedding confetti, and solving the mysteries of struggling container plants and stubborn succulents.
Producers: Dan Cocker, Matt Smith and Rahnee Prescod
