Gareth Richards, Jenny Laville and Guy Barter bring a jam packed show of highlights from the inaugural RHS Urban Show in Manchester - a festival of ideas focussed on greening up small spaces, looking after houseplants, and opening discussion about better urban planning. Amanda Grimes talks us through her easy-to-replicate designs for small (often concrete) spaces, including a Punk Rockery! Jason Williams aka The Cloud Gardener showcases seven innovative gardens designed with local communities that take on the challenges of urban gardening and development. Jacob James from Grow Tropicals talks us through his amazing display of rare and intriguing houseplants, with tips for different growing environments. And award-winning young designer Nathan Webster gives us a tour of his Urban Forest design, created to provoke conversation around the importance of woodland management in built up areas.

Single-colour planting, GYO tips (for radishes, peas, cardoons), and a floating greenhouse

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.
