Troubleshooting
Pelargonium 'Fragrans' problems — and how to fix them
Pelargonium 'Fragrans' (Pelargonium 'Fragrans') 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.
Loss of compactness
Low light makes this naturally neat plant stretch and open up. Move into full sun and pinch growing tips to maintain its tidy dome.
Root and stem rot
Its small fleshy stems rot quickly in wet compost. Use a lean, gritty mix, water only when dry and ensure the pot drains freely.
Botrytis and rust
Damp, crowded growing conditions cause grey mould and rust pustules. Space plants, improve airflow, remove affected leaves and keep foliage dry.
Aphids on new shoots
Soft growth attracts aphids under glass. Inspect tips regularly and treat early with insecticidal soap or a water jet.
