How to ripen your pears, the magic of the moving Mimosa plant, and Kumquat curiosity

This week, David Maxwell heads to County Antrim where he meets a Canadian couple gardening in the shadow of Slemish. Judith and Hugh Jackson moved to the area from Vancouver after they both retired. They built a house in a rural area and they quickly realised that gardening at 300 metres above sea level meant they needed plants that can look after themselves. Judith reveals her friendly ‘thugs’ including the tough perennial Persicaria which cuts down on any weeding. In County Clare, the programme visits the Irish Seed Savers Association who look after Ireland’s heritage apple collection and conserve heritage seed varieties for the future. Ruth Bramley from Farmyard Nurseries shows David some of her favourite indoor plants including Mimosa, also known as the sensitive plant, which moves when it’s touched. In studio, Anna Hudson joins David with seasonal inspiration and the answers to questions including how to ripen pairs and what to do with a Kumquat! Email the programme at gardenerscorner@bbc.co.uk
