Pest identification
What's eating my halesia monticola?
Aphids
Signs: Sticky honeydew and curled new shoots; colonies of small green or black insects visible on stem tips in spring.
Control: Water jet, insecticidal soap, or neem oil; avoid excess nitrogen fertilizer that produces the lush growth aphids prefer.
Scale insects
Signs: Hard or soft waxy bumps on bark; gradual dieback of small branches; honeydew and sooty mold on leaves below.
Control: Horticultural oil applied during dormancy smothers eggs; systemic imidacloprid soil drench for severe infestations.
Deer
Signs: Bark rubbed or stripped by antler fraying; young shoots browsed, leaving ragged torn edges on leaves and stems.
Control: Tree guards or wire cages around trunks of young trees; deer repellent sprays reapplied after rain.
