Gardening with the RHS

With the first glimmers of spring starting to show through, this week we’re diving into the theme of wellbeing – both for us and our garden wildlife. RHS Science & Horticulture Editor Olivia Drake joins us to explain why the common primrose is an essential early source of nectar for pollinators. We’ll also be exploring the powerful role gardens can play in our own health and wellbeing. The RHS has just launched a new science-backed Wellbeing Blueprint, designed to help anyone create a garden that actively supports wellbeing. Ashby Sachs and Vicky Shearing, who worked on the project, join us to talk about what the research reveals, and how we can all put those insights into practice. And finally we’ll also be dropping by the World Food Garden at RHS Garden Wisley, where edibles expert Liz Mooney will be showing us how, where and when to sow peas for a great harvest later in the year.

This week, we’re leafing through the pages of The Plant Review to explore a simple question: what can we learn from the wild? American plantsman Daniel J. Hinkley reflects on a lifetime of exploration that has taken him to some of the wildest places on Earth in search of plants. Yet in his article he turns his attention to a small, unassuming genus growing close to home in Washington State: Coptis. Next, David Pearce, curator of Abbotsbury Subtropical Gardens, transports us to the cloud-shrouded mountains of Madeira to meet a striking architectural plant found nowhere else in the wild, and one that he’s been successfully cultivating on the Dorset coast. And finally, Sacchi Parasrampuria and James Miller take us to Poon Hill in Nepal, reflecting on a recent plant observation trip and the lessons they brought back from the Himalayas.

This week, we’re heading to RHS Garden Wisley to discover how its horticulturists are turning one of the wettest starts to the year on record into a garden that’s primed for spring. Team leader Helen Bensted-Smith shares some top tips for gardening in persistently soggy conditions, and explains why increasingly wet winters and dry summers are challenges we need to adapt to rather than battle against. Guy Barter takes us on a seasonal stroll through Oakwood, which is coming into its own at this time of year, and has plenty of take-home ideas for gardening in damp shade. And finally, we popped in to see Liam Anderson, who’s hard at work pruning the 75m Wisteria Walk. In just a few months, it will be transformed into a spectacular tunnel of cascading purple and white blooms.

This week, as its delicate catkins unfurl on bare branches, Digital Science Editor Olivia Drake introduces this month’s RHS Wildlife Wonder plant — the hazel – which not only supplies queen bumblebees with much needed early pollen, but also provides tasty nuts and abundant leaves to support a huge range of wildlife throughout the year. And while it may still be a little early to sow most crops directly outdoors, if you’ve got a greenhouse or warm windowsill you can get a head start on the growing season. Down at RHS Garden Wisley, Liz Mooney is busy sowing aubergines, sweet peppers and chillies, and she’ll be sharing her top tips for getting the best from these heat-loving crops. Finally, Professor Ross Cameron from the University of Sheffield – author of Plants Can Save Your Life – joins us to explore the science of plants and wellbeing, and how indoor gardening can play a powerful role in boosting our health.

Now is a great time to start planning what to grow, and this week, we’re diving headfirst into the seed catalogues for inspiration! We’re exploring some of the tastiest, and most eye catching, additions to the veg patch: heirlooms! We also take a deep dive into tomato cultivars, as Liz Mooney shares her top picks from last years 'tomato extravaganza’ which saw her grow more than 50 varieties at RHS Wisley's world food garden. And finally, let's get back to basics with the foundation of any abundant veg plot: the soil! Nick Turrell and Jenny Laville dig into the ins and outs of how to care for earth beneath your feet.

As 2025 comes to a close, host Nick Turrell looks back on a year of discovery in this special end-of-year edition of Gardening with the RHS. From the quiet resilience of winter-flowering hellebores with plantsman John Grimshaw, to the gentle industry of hoverflies with RHS entomologist Josie Stuart, and a summer journey into Britain’s rare temperate rainforests with designer Zoe Claymore, this reflective episode revisits three listener favourites that reveal how even the smallest patches of nature can support a much wider living network.

Oh the weather outside is frightful but there’s still plenty of wonder to be found out there. James Armitage, editor of The Plant Review, joins Gareth Richards to reflect on the quiet beauty of the resilient plants that carry us through the winter months, and on the quiet beauty of seeing familiar plants anew.We begin with writer and plantsman Phil Clayton, who tells the extraordinary story of the Wollemi pine, tracing its journey from near-extinction to gardens around the world. James then sits down with Tom Christian to discuss the remarkable diversity of the ivy family, a group of plants rich in variety and resilience, whose beauty and horticultural value are often underestimated. Finally, we meet South Korean artist Seong Weon Ahn, whose delicate paintings capture plants not only with botanical precision, but with a deep sense of presence and mood.

This week, we honour the stillness of winter and the returning promise of light as we mark the winter solstice. At this turning of the year, we reflect on the people, plants and initiatives that this new light brings into focus. We begin by stepping into the richly curious world of Christopher Lloyd, the influential gardener and visionary behind Great Dixter House and Gardens. His legacy is recalled by his former student and now Head Gardener at Great Dixter, Fergus Garrett. Nick Turrell then returns with his top 10 countdown of plants that changed human history. This time, Nick delves into one species that helped ignite a vast global industry, asking whether its influence has ultimately made our lives better or worse. Finally, a look to the future with Sara Redstone who shines a light on a pioneering initiative taken up by theRHS, focused on strengthening plant biosecurity, highlighting the vital work being done to protect our plants and ecosystems for generations to come.
