What's eating my parthenocissus henryana?

Chinese Virginia creeper faces the same outdoor pest range as its relatives — leafhoppers and scale are the most frequent culprits. Vine weevil can notch leaf edges at night, and aphids occasionally colonise soft new growth in spring. Vigorous regrowth usually compensates for moderate damage.

White or pale stippling across leaf surfaces; shed nymphal skins on the underside; leaves may look scorched in severe cases. Spray insecticidal soap or neem oil onto leaf undersides, repeat every 7–10 days; encourage predatory insects by planting nectar-rich companions nearby.

Hard brown bumps on stems and leaf midribs; honeydew deposits lead to black sooty mould; overall vigour declines. Apply horticultural oil in early spring; wipe accessible surfaces with alcohol-soaked cloth; systemic neonicotinoid as a last resort only.

Irregular notches around leaf margins eaten at night by adult beetles; larvae in the soil eat roots causing sudden wilt. Apply pathogenic nematodes (Steinernema kraussei) to moist soil in late summer/autumn to target larvae; hand-pick adults after dark with a torch.
