Gardeners’ Corner heads to County Donegal where David Maxwell and Brendan Little visit some of the gardens that make up the Donegal Garden Trail. Glenveagh Castle gardens sit within a National Park. Sean O Gaoithin gives a guided tour of the walled garden and the native woodland where exotic plants also find a home. At Cluain na dTor, Seamus O’Donnell shows David and Brendan how to make use of the space below deciduous trees and how to make sure they can withstand the winds from the nearby Atlantic coastline. David also chats to Brendan about his recent cancer treatment and how he has found comfort in his Kerrykeel courtyard.
