Hi all, Ireland calling here. Does anyone know of a way that i can deter sheep from grazing on the bark of apple trees in our orchard. they have done an excellent job at keeping the grass short but they now have a taste for the apple trees. It is not as simple as moving them out of the orchard as they are regularly moved out when the grass is depleted, but when they come back they go at the trees again. Is there a propriety spray or wash that can be used on the trees? Thanks Darren
