In Gardeners' Corner this week David Maxwell visits Rowallane where Head Gardener Averil Milligan explains to him why the magnificent rhododendrons and camellias do so well there. Averil also has plenty of advice on how to grow them and what problems to look out for. Also in the programme David is joined by Barbara Pilcher at Glenveagh School where teacher Maire McCaughey and her pupils are very excited about three new raised beds and a soon to be built polytunnel have been created for growing vegetables for the kitchen. Brendan Little and Helen Mark are also in the veg garden planting up garlic and shallots.
