What's eating my schizanthus pinnatus 'angel wings'?

Schizanthus 'Angel Wings' is a delicate cool-season annual most vulnerable to aphids, which quickly colonise its soft stems and intricate flowers, and to slugs and snails on young seedlings. Spider mites may appear under glass or in warm spells. Grow in well-ventilated spots, water at the base, and check weekly.

Dense clusters on tender stems and flower buds; distortion, honeydew, and sooty mould Spray thoroughly with insecticidal soap or neem oil; remove heavily infested growing tips by hand

Seedlings consumed at soil level; ragged holes in young foliage; silvery slime trails Scatter iron phosphate pellets at planting; use copper barriers on containers; hand-pick at night

Fine webbing and pale speckling on leaves, especially on plants grown under glass in warm, dry conditions Raise humidity; mist foliage; apply neem oil or soap spray targeting leaf undersides
