The garden lost under a car park, taking on a mature garden and Adam Frost’s shrub of the month

With the arrival of an early summer, David heads to Bangor where a non-gardening couple took on a beautiful mature garden 9 years ago. Janet and her husband Carl had lived in South Africa, Germany and England, but it was only in taking on their garden near Ballyholme Beach that they got into all things green. David tours the suburban plot and finds out how it has connected them with neighbours and taught them patience. In Kilkenny, David explores the restored 17th century garden behind Rothe House which was lost under a car park until 2008. Gardener Mary Pyke explains how archaeology helped them recreate the generous merchant house plot. Adam Frost chooses the ‘Dunwich Rose’ as his shrub of the month and Claire McNally joins David in studio to answer questions including one on how to raise the popular cottage garden plant Aquilegia from seed.
