In a packed Gardeners' Corner programme, David Maxwell starts his new herb garden with advice from Barbara Pilcher. He catches up with Averil Milligan at Rowallane where work is going on to tidy up the walled garden and give some plants a winter rest. Also in the programme, Helen Marks finds out from Brendan Little how to make a paradise patio and Claire Barnett from the RSPB joins David in studio with all the information about the 40th annual Big Garden Birdwatch.
