Can weeds be useful? This week David Maxwell meets Becky Cole at Broughgammon Farm near Ballycastle. She considers some weeds free food and uses others for their useful herbal properties. Down in Slane, County Meath, Rosie Maye has a selection of attractive plants that can give those problem weeds a run for the money - Lamium, Lady’s Mantle, Euphorbia robbiae are top of the list. Also on the programme, Helen Mark visits the historic Drenagh Estate in Limavady where the gardens are being tamed after decades as a jungle and the Chelsea designer who is creating a ‘high maintenance’ garden for spinal patients in Belfast.
