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.
