Ligustrum vulgare · Shrub
Privet aphid: Tolerate minor damage as natural predators usually control populations by mid-summer.
Honey fungus: Improve drainage and avoid planting in soil previously infected; remove severely affected plants.
Verticillium wilt: Remove and burn infected material to prevent spread; avoid replanting privet in the same spot.
Scale insects: Scrape off small infestations or use horticultural oil sprays in early spring before they hatch.
Leaf-mining moths: Prune out heavily infested leaves; damage is usually cosmetic and rarely harms established plants.
