The 2026 RHS Chelsea Flower Show is celebrated as the world’s greatest floral spectacle, with Gardeners' Question Time delivering expert insights across its dazzling gardens. From moles turning clay soil into free compost to the King’s Foundation’s Curious Garden—championed by Charles III, David Beckham, and Alan Titchmarsh—this episode blends horticultural wonder with practical wisdom. The panel, including Matthew Wilson, Pippa Greenwood, and Bethan Collerton, tackles real gardener dilemmas: how to manage molehills on heavy soil, grow vegetables in salty coastal winds, and create dried flower confetti for weddings. They also explore how urban container gardens can be both accessible and biodiverse, while science teams reveal how sound and soil monitoring can track underground life. A standout moment comes with the Children’s Society Garden, a sanctuary designed to support teenage mental health through nature, embracing imperfection and recycled materials. The episode closes with heartfelt tributes to long-time panellist Matt Biggs, who passed away after a battle with cancer, underscoring the deep personal connections within the gardening community.
Use molehills from clay soil as free compost—especially when damp, as they’re rich in nutrients and seed beds.
For windy coastal gardens, grow salt-tolerant vegetables like chard, tomatoes, and leeks, which benefit from air movement.
Dry flower confetti by hanging petals upside down or using a flower press—start now if your wedding is in August.
Plant medlar or crabapple trees for fast-growing, fruit-bearing, bushy options ideal for noise reduction and making jam or gin.
Use sound and soil monitoring tools to detect underground biodiversity—worms, beetles, and even solitary bees make unique acoustic signatures.

Molehills, Clay Soil, and Compost Gold
“I would sort of split the difference. I think do a bit of spreading out. But when it's really damp, when they appear, then I would actually try and collect them up because... it's the best seed compost you could ever get.”
The King’s Foundation Curious Garden: Plants with Purpose
Frances Topbell reveals the concept behind the Curious Garden, a celebration of plants’ historical, economic, and cultural roles. Designed with input from Charles III, Beckham, and Titchmarsh, the garden features handmade crafts, dyes, and rare plants like Nepeta Six Hills Giant and garlic.
Coastal Gardening: Surviving Wind and Salt
“If you've got that sea breeze, they're quite protected from blight which comes in on the wind. So that can be really helpful.”
Dried Flower Confetti: From Garden to Wedding
The panel advises on growing and drying flowers for wedding confetti. They recommend buttercups, rose petals, and chamomiles, emphasizing slow drying via flower presses to prevent rot.
“We rarely saw Matt without a huge smile on his face. We love him and the whole GQT family will miss him enormously.”
“Perfection being something which is debilitating, I think, to young people and which they get hit with left, right and centre through social media.”
“If you find those, you're going to have to use a biological control to try and wipe them out and or maybe even dispose of the plants if they're in really heavy infestation levels.”
