Desert roadcuts, abandoned pasture, heathland and marshy thickets inspire naturalistic planting ideas from Kevin Philip Williams and Michel Guidi, whose new book Shrouded in Light draws from wild shrubscapes. We also visit RHS Garden Rosemoor in North Devon, where Peter Adams gives us a tour of the extensive fruit and vegetable gardens with top tips for growing parsnips, shallots, cloching potatoes and protecting peas. Jenny Laville and James Armitage return to the podcast to debunk more plant terminology – this time talking about “hybrids” – what they are, how they occur and how they can be used to your advantage.

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 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.
