What's eating my pelargonium crispum 'variegatum'?

Aphids

Signs: Soft green or black insects clustered on shoot tips; honeydew, leaf curl, and stunted growth.

Control: Remove by hand or water jet; apply neem oil or insecticidal soap spray; use Aphidius parasitic wasps in greenhouse settings.

Whitefly

Signs: Clouds of tiny white flies when foliage is disturbed; yellowing, sticky leaves coated with sooty mould.

Control: Hang yellow sticky traps; spray with insecticidal soap or pyrethrin; ensure good airflow to discourage colonies.

Spider mites

Signs: Pale speckling on upper leaf surface; fine webbing on leaf undersides, worst in warm dry rooms.

Control: Mist foliage and increase humidity; wipe leaves with damp cloth; apply neem oil or predatory mite Phytoseiulus persimilis.

Vine weevil

Signs: Notched leaf margins at night; grubs destroy root system in containers, causing sudden wilting.

Control: Nematode drench (Steinernema kraussei) in late summer; check and clean roots when repotting each spring.
