Pruning Roses and Planting Potatoes on St Patrick's

David Maxwell is joined in the studio to talk about two garden tasks usually done around St Patrick's: pruning roses and planting potatoes. Barbara Pilcher makes her first visit to David's garden to see how he is getting on with starting a new herb garden. David also visits a grand garden gone wild - Annesgrove in County Cork and he finds out about the importance of looking after our soil at Maurice Parkinson's garden in Ballyrobert.
