What's eating my solanum crispum 'glasnevin'?
Whitefly (Trialeurodes vaporariorum)
Signs: Nymphs cluster on leaf undersides causing yellowing; adults flutter when disturbed; sooty mould develops on honeydew, reducing ornamental appeal
Control: Yellow sticky traps; spray leaf undersides with insecticidal soap every 4–5 days; introduce Encarsia formosa under glass; avoid excess nitrogen fertiliser
Aphids (Myzus persicae and others)
Signs: Distorted shoot tips and flower buds, sticky honeydew, and sooty mould; ants farming aphid colonies may be a first sign
Control: Blast off with water; apply neem oil or insecticidal soap; encourage ladybirds, hoverflies, and lacewings as biological control
Spider mites (Tetranychus urticae)
Signs: Fine pale stippling on upper leaf surfaces; webbing on undersides during dry summers; severe infestations cause leaf yellowing and drop
Control: Keep plant well-watered; spray foliage with water; apply neem oil or a registered acaricide for persistent mite populations
Slugs and snails
Signs: Ragged holes in young shoots and leaves at the base, most severe in spring after mild wet periods
Control: Apply ferric phosphate pellets; use grit or copper-tape barriers; hand-pick at night; encourage hedgehogs and ground beetles
