Mary Keen, children who are keen and everything in between

This week, David visits Rosie Maye’s garden near Slane and hears about her love of Inter-planting and underplanting. Prolific Irish garden designer Mary Keen chats about new autobiography, Diary of a Keen Gardener, and why even with her long career and expertise, she’s always learning and experimenting as a gardener. Pupils from Hezlett Primary School and National Trust volunteers help plant ferns and unveil a new water bowl at Downhill Demesne, Castlerock. Gardening expert Neil Porteous joins David in studio to help caller John, who’s worried about cutting his holly tree and Pearl, who’s wondering how best to overwinter potted gladioli.
