Snowdrops, scented shrubs and St Columb's Park Walled Garden

David Maxwell presents Northern Ireland's weekly gardening programme with advice on the best snowdrops and winter flowering shrubs. He also visits a restored Walled garden at St Columb's Park in Derry which is going to be gardened by the community. Also in the programme, Keith Crawford is in studio to talk about how to put that discarded Christmas tree to good use as well as some winter pruning jobs to do right now.
