Garden designer and writer Ann Treneman shares ideas from her new book RHS Greener Gardening: Containers, explaining how you can create sustainable ecosystems whatever size your space. Jenny Laville speaks with RHS botanist James Armitage to untangle taxonomy, and discuss why plant names keep changing. And Gareth Richards meets David Ford, the holder of the National Plant Collection of Chaenomeles in Surrey, to talk about his love affair with the plant and why they’re due a mainstream revival.

This week Guy Barter and RHS Sustainability Fellow Chloe Sutcliffe react to a recent study published in the journal Nature Cities that claims that urban agriculture has a carbon footprint up to 6 times bigger than conventional agriculture – discussing what this means for allotmenteers and community gardeners, and how we should be thinking about our environmental impact. Entomologist and wasp defender Serian Sumner explains why spring is the perfect time to make peace with yellowjackets, as the queens emerge from hibernation. And the RHS’s Adrian Thorne gives us a practical guide to pruning shrubby hydrangeas.

This week, we’re trying to honour March in all its glory. We’re delving into tasty and blight-resistant tomato varieties. We’re exploring how to build and renovate harmonious and colourful borders. And finally, to celebrate International Women’s Day and the 220th anniversary of the RHS, we’re turning back the clock to honour a few of the women who’ve shaped the organisation.

This week we’re exploring small but useful nuggets of information that have the potential to change the way we interact with our surroundings this growing season. We’re getting seasonal tips on GYO – things like training and pruning apple trees and preparing allotments for the busiest time of year. And, we’re delving into plant names – and the system behind our classifications.

This week, we’re investigating what exactly makes a plant hardy, how tropical plants survive British winters, and the ways in which what thrives here may be changing – especially in urban environments like London. Presenter Gareth Richards and RHS botanist James Armitage take a tour of weird and wacky tender trees that have survived here against all odds. And, Hillary Collins of Grafton Nursery gives us a behind the scenes look at what you can do to help your eucalyptus withstand British winters.

This week’s show is all about growing something new. We’re spreading the word about exciting plant species, cultivars, and hybrids from those that love them most. Legendary plantsman Roy Lancaster chats about shrubby honeysuckles, Canadian horticulturist Grahame Ware makes the case for a curious genus called Syneilesis, and Wisley horticulturist Jack Aldridge shares the stories behind flowering dogwood hybrids.

All the stories in this show are based on articles from the March issue of The Plant Review. You can find information on how to subscribe here.

For this week’s show, we take a behind the scenes look at the ways spring is fighting its way into the picture at RHS Garden Wisley. We go behind the scenes at the Alpine Display House, we get a masterclass on pruning wisteria, and we dive into the life and work of the eccentric and influential horticulturist Ellen Willmott – and explore a theory for why she may have missed her Victoria Medal of Honour ceremony.

In this week’s show, we’re zeroing in on how to stretch the money we spend on our gardens as far as possible. We hear from gardening influencer Anya Lautenbach - aka Anya the Garden Fairy – on her money-saving tips. We explore the science behind cuttings with botanist and editor James Armitage. And we take an inside look at the RHS apprenticeship programme.

This week’s show is all about cultivating change – whether in your own garden, in your local neighbourhood, or in a magical National Trust property. We’re chatting guerrilla gardening with Ellen Miles, getting top tips from Wisley advisors, and taking a look at all the work that goes into maintaining the laburnum arch at Bodnant Garden (one of our most beloved partner gardens!)

As gardeners, we all have plants we love to hate – think aucubas or heathers. And in winter, especially, it seems that these common but unpopular plants play a really important role in our gardens, adding structure, berries, or cheery variegated leaves when we need it most. So today, we’re addressing the overlooked. We’re giving mahonias a well-deserved second chance. We’re revisiting houseplants, which may or may be looking worse for wear after the chaotic holiday season. And finally, we’re taking a look at the work The Glasshouse, a nursery in Kent, does to give women in prison a fresh start.
