Overview: Jim, Carole and George investigate some neglected mature shrubs. Jim looks at the flowering quince, while Carole and George tackle the berberis and the pyracantha. Continuing to trace the path of a gardener's training, Jim visits Elmwood College in Cupar to find out about apprenticeships in the lovely college gardens. Carole visits the impressive Braco Castle garden in Stirlingshire, which features a range of rhododendrons that are designed to have a very long season of flowering.
