Viburnum tinus is another spring flowering shrub which needs to be cut back now. When pruning, keep a lookout for the viburnum beetle, as this tiresome pest can defoliate the plant’s leaves. Most of the damage is caused by the larvae in spring but the adult beetles can cause further harm in late summer, with severe attacks spoiling much of the foliage. Damaged leaves are often discoloured with brown, dried up edges around the holes.
Strangely, if damaged by the beetle, this species of Viburnum can produce an unpleasant smell when wet. The best thing to do is to cut back the stems after flowering and then spray with a systemic insecticide. As with all chemicals, never spray plants in flower as this could cause harm to pollinating insects.
Your roses might also benefit from a fortnightly spray with an insecticide or fungicide to keep blackspot and greenfly at bay.
