In this week's Gardeners' Corner there's lots of work to be done in the garden at the beginning of March. Time to sow seeds, Brendan Little is sowing lettuce, beans and peas and Barbara Pilcher is sowing her favourite tomatoes. Also in the programme help with pruning wisteria and roses for a good summer show and Ann Fitzsimons is on hand with advice on planting up David's new pond. That's Gardeners' Corner with David Maxwell this Saturday morning just after the nine o'clock news on BBC Radio Ulster.
