Pest identification
What's eating my dittany of crete?
Aphids
Signs: Small colonies on softer, less-woolly new shoot tips; honeydew makes leaves sticky and attracts sooty mould.
Control: Spray with insecticidal soap or water jet, targeting shoot tips. Avoid nitrogen-heavy feeding. Encourage ladybirds and hoverflies by planting companion flowers nearby.
Spider mites
Signs: Fine pale speckling on leaves if grown in very warm, dry indoor conditions; the woolly coat limits spread.
Control: Move the plant to better air circulation and mist occasionally. Apply diluted neem oil spray if mites are confirmed; the hairy leaves make full coverage difficult.
Leafhoppers
Signs: Pale silvery flecking on the upper leaf surface; less common than on smooth-leaved oreganos due to the dense pubescence.
Control: Insecticidal soap sprays help control nymphs. Keep plants in open, airy positions with good airflow to reduce leafhopper pressure.

What is eating my dittany of crete?
Dittany of Crete (Origanum dictamnus) is a compact, densely woolly-leaved herb from dry Mediterranean hillsides. Its thick felt covering physically blocks many sap-sucking insects. Aphids occasionally attack new growth, and spider mites can appear in over-dry indoor conditions if grown as a pot herb. It is one of the most pest-resistant Origanum species.
