Troubleshooting
Pelargonium x asperum problems — and how to fix them
Pelargonium x asperum (Pelargonium x asperum) 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.
Weak fragrance and legginess
Sparse, poorly scented growth comes from too little sun. Give full light and pinch regularly to build a dense, aromatic bush.
Yellowing leaves
Lower-leaf yellowing usually signals overwatering. Let the soil surface dry between waterings and ensure the pot drains freely.
Rust and botrytis
Orange pustules or grey mould appear in damp, crowded conditions. Improve airflow, remove affected leaves and avoid overhead watering.
Whitefly and aphids
Soft new growth attracts sap-sucking pests indoors. Inspect undersides of leaves and treat early with insecticidal soap.
