Gardening with the RHS

The A-mazing guide to hedges

Listen on

Episode notes

Our Chief Horticulturist Guy Barter wanders into Hampton Court Palace's historic yew maze to meet Gardens Manager Graham Dillamore. Once haunt of kings and queens, this 300 year old spread of tortuous topiary now welcomes thousands of visitors and contains valuable lessons for modern-day gardeners too. Guy offers hedge planting and maintenance advice before handing over to Dr Stephanie Bird who shares the latest thinking on box tree moth, a recent arrival to Britain that can devastate plantings of box (Buxus sempervirens).

Did you know that hedges have some powerful environmental benefits? Recent RHS research shows they can reduce pollution levels, help prevent flooding and even provide habitat for wildlife and food for pollinators. RHS scientist Dr Mark Gush explains more, and shares details of the best plants to use.
