Pelargonium 'Deacon Fireball' problems — and how to fix them
Pelargonium 'Deacon Fireball' (Pelargonium 'Deacon Fireball') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Botrytis on dense flower heads
The packed double blooms hold moisture and develop grey mould. Deadhead often and ensure good airflow around the plant.
Rapid drying in containers
Heavy bloom and a compact root ball dry quickly in heat. Monitor daily in summer and water before the compost pulls away from the pot.
Reduced flowering
Shade or excess nitrogen produces leaves instead of flowers. Provide full sun and a high-potash feed.
Pelargonium rust
Brown pustules on the leaf undersides spread in crowded, humid conditions. Remove infected leaves and improve ventilation.
