Troubleshooting
Pelargonium odoratissimum problems — and how to fix them
Pelargonium odoratissimum (Pelargonium odoratissimum) 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, scentless growth
Too little light stretches stems and weakens the apple fragrance. Move to full sun and pinch tips to rebuild a bushy, aromatic mound.
Stem and root rot
Overwatering or dense compost rots the soft, fleshy stems from the base. Use gritty mix, water only when the surface is dry, and never leave it standing in water.
Botrytis (grey mould)
Cool, damp, crowded conditions cause fuzzy grey patches on leaves and flowers. Improve airflow, remove affected parts and avoid wetting the foliage.
Aphids and whitefly
Soft new growth attracts sap-suckers under glass. Inspect leaf undersides and treat early with a jet of water or insecticidal soap.
