This week, David Maxwell heads to Hillsborough Castle where thousands of daffodils are in bloom. Head gardener, Claire Woods explains how this versatile spring bulb can be grown in containers, borders and lawns. Nearby, enthusiast Richard McCaw has been growing and showing daffodils since 1989. He shows David where his new varieties begin life in a little plot of land behind his home. At Laurelbank Farm in County Down, Jo Facer is bringing in the harvest. It's something she does on her market garden 52 weeks of the year. Jo reveals two crops that are well worth the effort - beetroot and kale. Ann FitzSimons will join David in studio to answer questions and provide some seasonal inspiration. Contact the programme on gardenerscorner@bbc.co.uk
