Carrot-leaved Pelargonium problems — and how to fix them
Carrot-leaved Pelargonium (Pelargonium rapaceum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Tuber rot during summer dormancy
The most common cause of loss: watering continues after the leaves die down in late spring. Store the potted tuber completely dry and in a warm, airy spot from late spring to early autumn.
Fungal leaf spot
Dark spots on the feathery foliage in humid or poorly ventilated conditions. Improve air circulation, avoid overhead watering, and remove affected leaves; rarely serious if conditions are corrected promptly.
