What's eating my cape primrose 'bristol's party girl'?

Streptocarpus 'Bristol's Party Girl' is an indoor cape primrose. Vine weevil grubs can devastate the root system; tarsonemid (cyclamen) mites disfigure young leaves and flowers; mealybugs colonise leaf undersides. Aphids attack new growth in spring. Good hygiene and regular inspection of leaf undersides catch problems early.

Cream C-shaped grubs eat roots; plant wilts suddenly and collapses with little warning; notched leaf margins from adult beetles Apply pathogenic nematodes (Steinernema kraussei) to moist compost in spring or autumn; use imidacloprid drench as a chemical option

Severely distorted, stunted new leaves; flowers streaked or deformed; growing centre looks silvery and twisted Remove and bin severely affected leaves; apply abamectin or predatory mite (Amblyseius cucumeris); avoid water-splashing between plants

Fluffy white wax on leaf undersides and in the crown; leaves yellow and growth stalls Dab with alcohol swab; spray with insecticidal soap or neem oil weekly until eradicated

Soft clusters on young flower stems and petioles; curl and distort; leave sticky honeydew Spray with insecticidal soap or a strong water jet; repeat every 5–7 days; check for ants farming colonies
