Troubleshooting
Coconut-Scented Geranium problems — and how to fix them
Coconut-Scented Geranium (Pelargonium grossularioides) 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.
Leggy, sparse growth
Caused by too little light; move to full sun and pinch tips regularly to keep the plant bushy and fragrant.
Root rot and stem blackening
From overwatering or poor drainage; let soil dry between waterings and use a gritty, free-draining mix.
Geranium rust and botrytis
Orange leaf-underside pustules or grey mould appear in damp, crowded conditions; improve airflow, avoid wetting foliage and remove affected leaves.
Aphids and whitefly
Cluster on soft new growth and flower buds; rinse off or treat with insecticidal soap, checking leaf undersides.
