Troubleshooting
Pelargonium 'Vancouver Centennial' problems — and how to fix them
Pelargonium 'Vancouver Centennial' (Pelargonium 'Vancouver Centennial') 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.
Foliage colour fading to green
Almost always too little light. Move to the brightest spot available; the bronze-gold zoning is light-dependent and washes out in shade.
Botrytis (grey mould)
Grey furry mould on leaves and faded flowers in damp, crowded conditions. Improve airflow, remove dead foliage and spent blooms promptly, and avoid overhead watering.
Pelargonium rust
Concentric rings of brown pustules on leaf undersides. Remove affected leaves, space plants for ventilation, and avoid wetting foliage; this disease is specific to zonal pelargoniums.
Leggy, sparse growth
Caused by low light or skipped pinching. Pinch out shoot tips in spring and grow in full sun to keep the plant dense and well-flowered.
