Troubleshooting
Pelargonium 'Ardens' problems — and how to fix them
Pelargonium 'Ardens' (Pelargonium 'Ardens') 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.
Tuber rot
Watering during summer dormancy or growing in heavy soil rots the tuberous roots. Keep it dry while resting and use a very gritty, fast-draining mix.
Shy flowering
Poor bloom usually means too little sun or feeding during dormancy. Provide full sun and feed only during active growth with high-potassium fertiliser.
Summer dormancy
Dieback in summer is the natural rest period, not failure. Reduce water to near nothing and resume care as growth restarts in autumn.
Fungal leaf disease
Damp, still conditions cause spotting and rot on the fine leaves. Maximise airflow and avoid wetting the foliage.
