What's eating my hedera colchica 'dentata variegata'?

Vine weevil (Otiorhynchus sulcatus)

Signs: Grubs eat roots causing sudden wilt; adult beetles leave characteristic D-shaped notches around leaf margins at night

Control: Drench with Steinernema kraussei nematodes in late summer when soil is above 5 °C; use barrier tape or grit mulch around pot rims

Spider mites (Tetranychus urticae)

Signs: Pale stippling and fine webbing on leaf undersides; variegated areas lose colour contrast; leaves bronze and drop in severe infestations

Control: Improve air movement and mist foliage; release Phytoseiulus persimilis; spray with dilute neem oil or a registered acaricide

Aphids (Aphis hederae)

Signs: Dense colonies distort soft shoot tips, excrete honeydew, and encourage sooty mould that obscures the attractive leaf variegation

Control: Remove by hand or water blast; apply insecticidal soap or neem oil spray; rely on natural predators where populations are mild

Scale insects (Pulvinaria regalis)

Signs: Waxy brown shells encrust stems; sooty mould grows on honeydew beneath, dulling the ornamental foliage

Control: Scrub off manually with soapy water; apply horticultural oil when crawlers are active in late spring
