What's eating my miss kim lilac?

Aphids

Signs: Colonies on soft spring shoot tips causing leaf curl and sticky honeydew deposits.

Control: Knock off with a water jet; insecticidal soap spray; promote natural predators by minimising pesticide use.

Lilac borer (Podosesia syringae)

Signs: Larval tunnels in stems with frass; shoot dieback and weakened branches in established plants.

Control: Prune out and destroy affected wood. Permethrin spray on trunks/stems in late spring when adult moths emerge.

Oyster shell scale (Lepidosaphes ulmi)

Signs: Grey encrusting scales on stems, reducing vigour; sooty mould may follow honeydew.

Control: Dormant horticultural oil spray in late winter; hand-removal of visible colonies.

Rabbits

Signs: Gnaw bark at the base of young plants through winter, potentially ring-barking them.

Control: Wire mesh collar or plastic tree guard from ground level to 60 cm; remove during growing season.
