Enjoy a tour around RHS Garden Wisley’s Bowes-Lyon Rose Garden with its 4,500 roses and find out how to keep yours blooming until autumn. We discover how this iconic plant became the favourite (and least loved) flower among the British with historian Simon Morley, then author Gareth Richards sings the praises of a rose relative, the bramble, ‘nature’s frontline defender against man’. Finally, find out about the pest-busting wasp you definitely need in your garden this summer.
