Growing Ideas: Highlights from RHS Hampton Court

This week, we're coming to you from the stunning RHS Hampton Court Palace Garden Festival 2025; the UK’s most spectacular summer celebration of all things green, growing, and gloriously garden-inspired! Join us as we dive into the cutting-edge sustainability solutions, and thought-provoking exhibits that reveal how gardening connects us to nature, to each other, and to ourselves. We explore the Healer’s Hollow, where ancient plant-based healing traditions are brought back to life, and visit Surrey County Council’s visionary garden, which imagines a greener, more sustainable urban future. Along the way, we hear from passionate exhibitors and garden designers about how we can support endangered garden wildlife—and they share their top tips for keeping your garden thriving, even in this summer’s scorching heat.   Hosts: Guy Barter, Mellissa Mabbitt, Tom Howard   Contributors: Jude Yeo, Emily Grayshaw, Lilly Gomm, Coralie Thomas, Adrian Thomas, Alan Partridge, Helen Currie, Tom Pilgrim, Laura Strand, Sam Stark-Kemp, Henry T Pope   Links: Visit RHS Hampton Court Palace Garden Festival  RHS Healers Hollow Garden RSPB and RHS Swift Garden Surrey County Council: Reclaiming spaces, creating healthy streets garden Hot Pocket, City Pocket Planting Garden Teucer Wilson: Green the Gap Garden, City Pocket Planting Welcoming Wildlife, City Pocket Planting Garden

The Wildlife Trusts’ collaborator and garden designer Zoe Claymore shares her top tips on wildlife friendly gardening.

As the UK bursts into bloom, we celebrate British Flowers Week with flower farmer Georgie Newbery, who shares how to create stunning, sustainable bouquets from your own garden. At RHS Garden Wisley, Liz Mooney guides us through successional sowing for a summer full of salad crops, and at RHS Bridgewater, Carolyne Jones reveals how to turn your garden into a haven for nesting birds. From vibrant wildflowers to fledgling robins, it’s a glorious season of growth – and there’s still time to get involved.

This week, we journey into one of Britain’s rarest and most magical landscapes — the temperate rainforest. Designer Zoe Claymore joins us to reveal how she captured the enchanted atmosphere of these ancient woodlands at the RHS Chelsea Flower Show, and how you can recreate that wild, mossy magic at home. Then, we turn our attention to a true British garden staple: the hedge. Photographer Gareth Gardner shares what he discovered after receiving over 500 submissions from around the world for his new exhibition On The Hedge, now opening at RHS Garden Wisley. Plus, Gareth Richards is here with practical advice on planning ahead with tips on sowing biennials, and Guy Barter shares what he’s been up to in his own garden. A lush, leafy episode not to be missed.

This week, we’re stepping off the garden path and into the wild. James Armitage, editor of The Plant Review, joins Gareth Richards to reflect on how a little wilderness can bring balance, biodiversity, and unexpected beauty, to even the most cultivated spaces. We begin with a tribute to the intrepid botanist John Watson, whose plant-hunting adventures in South America unearthed a treasure trove of wild flora. Plantsman Robert Rolfe shares stories of Watson’s passion and the remarkable plants he helped bring into cultivation. Then, it’s over to the Garry oak meadows of Vancouver Island, where nurserywoman Amy Sanderson and writer Eric Hsu are rethinking everything we thought we knew about camassias – revealing their surprising resilience in dry climates. Finally, we ascend to the Himalayas with botanist Richard Moore to meet the hardy Roscoea – a plant both wild and wonderful, whose taxonomic tale is as twisty as its mountain roots. All this, plus a call to action: find out how you can help protect community growing spaces by supporting the RHS-backed Space to Grow amendment in Parliament.

Late May bursts with life – and this week’s episode celebrates the full force of the season. We revisit the RHS Chelsea Flower Show to explore the mystique of Meconopsis, the Himalayan “Big Blue Poppies” that have captivated British gardeners for over a century. Then, Horticultural Advisor Nick Turrell shares clever shortcuts for growing your own edibles – even if you’re short on time and space. And Edward Cooper from RHS Garden Wisley unpacks the Award of Garden Merit: what it takes to earn this mark of excellence, and how it can help you choose top-performing plants for your own patch.

Step into the bloom of RHS Chelsea 2025! In this special episode, we delve into the standout themes, emerging trends, and — of course — the spectacular plants that define this year’s show. Journey with us from Scotland’s wild coastal landscapes to the dappled canopies of urban forests, as we meet the visionary designers behind 2025’s most breathtaking gardens. We’ll also shine a spotlight on the real stars of the show: the plants themselves — and the groundbreaking breeders competing for the prestigious RHS Chelsea Plant of the Year award.   Hosts: Jenny Laville, Gareth Richards, Tom Howard, James Armitage   Links: Chelsea Flower Show tickets Chelsea Flower Show gardens Chelsea Plant of the Year RHS Hampton Court Palace Garden Festival RHS Flower Show Wentworth Woodhouse

Biodiverse spaces are important not only for healthy ecosystems but they also bring tangible benefits for our mental wellness as well. Unfortunately new data shows that some of our most loved garden visitors – the Lepidoptera, or butterflies and moths – are in alarming decline. We’ll be finding out from Dr Richard Fox, Head of Science at Butterfly Conservation, how gardeners can give them the boost they need. Ed Cooper from the trials team down at RHS Garden Wisley shows us another way of welcoming in not only butterflies and moths, but a whole host of other wildlife as well, with advice on sowing annual and perennial wildflower meadows. And finally, we find out how to maximise our outdoor spaces for our four legged friends, with Lead Horticulturist Dawn Grehan, at Battersea Dogs and Cats Home.   Host: Gareth Richards   Contributors: Dr Richard Fox, Ed Cooper, Dawn Grehan Links:  Butterfly Conservation Butterfly recording and monitoring RHS Plants for Pollinators RHS Chelsea Flower Show How to create a pet-friendly garden Potentially harmful garden plants

It’s Plant Health Week, and we’re celebrating with expert tips to keep your garden thriving. RHS Plant Health Advisor Helen Latham will be sharing practical advice to help your plants stay strong and resilient. Meanwhile, Nick Turrell returns to shine a light on the unsung heroes of the garden — weeds! Last week, he turned a common garden nuisance into a delicious, nutrient-rich summer salad. Today, he’s back with another surprising use for those persistent plants — and a fresh perspective on why they might deserve a second chance. Plus, as gardens burst into bloom, your questions have been flooding in. We’ve handed a few over to the RHS Garden Advisory Team to get the expert answers you’ve been looking for.
