Enthusiastic gardeners poured into a Harpenden hall recently for a recording of an iconic Radio 4 programme.

A full house in Park Hall greeted experts Matt Biggs, Ann Swithinbank and James Wong together with chairman Eric Robson for a recording of Gardeners’ Question Time hosted by Harpenden Gardening Society.

Questions addressed to the panel included compost composition, outlandish potatoes and replacement ideas for a 200-year-old beech tree about to be felled.

All the questions were answered by the experts who are not given any prior knowledge of what they will be asked.

The Harpenden recording is available to listen again here.
