Leaves greening / scorching
Green foliage signals too little light; bleached or crisped patches signal sudden harsh sun. Acclimatise gradually but keep it in good light to preserve the gold-and-bronze pattern.
Pelargonium rust
Brown pustules ringing leaf undersides, common on soft golden foliage. Remove infected leaves, improve airflow, and keep water off the leaves.
Botrytis (grey mould)
Grey mould on spent flowers and dying leaves in damp conditions. Deadhead regularly, clear debris, and ventilate well.
Yellowing lower leaves
Often overwatering or poor drainage. Let the compost dry further between waterings and ensure pots drain freely.
