With the heat wave continuing Gardeners’ Corner is live at Garden Show Ireland in Antrim Castle Gardens. David Maxwell is joined by Diarmuid Gavin, Cherry Townsend and Mary Doris who will take questions from an invited audience. Also on the programme, with house plants one of the big themes at this year's show, Conrad McCormick will pick some of his favourites and away from the show David heads to nearby Ballyrobert Cottage Garden where Maurice Parkinson believes that summer can be perhaps the best time to get new plants established in the garden.
