The RHS Hampton Court Palace Garden Festival returns for 2021. And what a return it is! From world-class garden design talent to new ways of growing cabbages, there's something for everyone. We explore the show's no-dig gardens, community allotments and experience some lively debates between horticultural experts in the talks theatre. Plus an interview with a cut-flower grower who overcame multiple tragedies in 2020 to bring a heartwarming and colourful garden to this year's show.
