Caring for Privet

Privet has moderate water needs and tolerates short dry spells once established, but young plants and hedges benefit from watering during prolonged dry periods in spring and summer—roughly once a week if there's no rain. Avoid waterlogging; privet dislikes sitting in saturated soil. Reduce watering in autumn and winter when growth slows. Feed in March or April with a general-purpose granular fertiliser such as Growmore or blood, fish, and bone, scattering a handful per metre along the base of a hedge and lightly forking it into the soil surface. A second, lighter feed in late spring supports the summer flush if growth seems weak, but avoid feeding after July as soft late growth is vulnerable to frost. Mulch annually in spring with garden compost or bark to suppress weeds, retain moisture, and add organic matter, keeping mulch a few centimetres clear of stems. Privet is generally trouble-free but can suffer from privet thrips in hot, dry summers—tiny insects that cause silvery mottling on leaves. Improve air circulation and water during dry spells to reduce stress. Honey fungus can occasionally affect privet, causing dieback; remove and destroy affected plants promptly. Leaf spot and powdery mildew may appear in damp, crowded conditions but rarely cause serious harm. Rake up and bin fallen leaves to reduce fungal spores. Though listed as evergreen, privet often drops some or most of its leaves in cold winters, especially in exposed sites or in zones 7–8. It reliably re-leafs in spring. No winter protection is needed in temperate Europe.
