They say that the proof of the pudding is in the eating. Well, this week in the Beechgrove Garden, Jim and Carole munch their way through the veg plot as they taste-test turnips, a new broad bean and some blight-resistant potatoes. Chris takes a look at the new rose garden and has a new take on some age-old remedies for common rose problems. George visits the grand Drummond Castle Gardens near Crieff in Perthshire. The formal garden and parterre are among the oldest in Scotland and reputedly some of the finest in Europe.
