Airfield Estate, decadent Dahlias and wildlife gardener Kate Bradbury

Just a few minutes walk from Ireland’s largest shopping centre, a garden provides a quiet place in the city. A haven for wildlife and place to learn about our food, Airfield Estate in Dundrum was left in trust to the people of Ireland by trailblazing sisters Letitia and Naomi Overend. They understood the importance of people self sufficient and sustainable, an ethos that continues today under head gardener Colm O’Driscoll. In this programme, David Maxwell has a tour with Colm and finds about the Totally Terrific Tomato festival. Also in the programme, David finds out from expert grower Charles Holmes what makes the perfect Dahlia and he chats to wildlife gardener Kate Bradbury about her new book encouraging us all to plant a tree for the planet.
