Rethinking rose pruning, self-sufficiency, and ornamental grasses Feb 26, 2026

Show notes

This week we join gardener and biologist Benny Hawksbee in his rose beds to find out how one small adjustment to the traditional rose pruning method can create vital habitat for a key aphid predator. RHS Garden Wisley’s Liz Mooney tells us about her journey to self-sufficiency, and horticulturist Rose Holman guides us through how to cut back your ornamental grasses before the new growth comes through.

Wet winter gardening, woodland walks and pruning wisteria Feb 19, 2026

Show notes

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.

The wildlife wonders of hazel, the science of winter wellbeing and hot crops from Wisley Feb 12, 2026

Show notes

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.

This week we’re rolling up our sleeves to look at how we can support our garden visitors, while also preparing for the burst of life that spring will bring. The RSPB’s Emma Marsh is back to share how monitoring projects like the Big Garden Bird Watch can make a real difference when it comes to helping our declining species.

A Year in the Garden: Hellebores, Hoverflies and Temperate Rainforests Dec 30, 2025

Show notes

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.

A Quiet Beauty: Plants That Carry Us Through the Cold Dec 23, 2025

Show notes

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.
