Zantedeschia 'Hot Chocolate' problems — and how to fix them
Zantedeschia 'Hot Chocolate' (Zantedeschia 'Hot Chocolate') 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.
Rhizome rot
Overwatering and cold, wet soil cause soft rot. Use a free-draining mix, water moderately, and keep dormant rhizomes dry and frost-free.
Sparse flowering
Low light or high-nitrogen feeding favours leaves. Move to brighter light and use a potassium-rich feed to encourage the chocolate spathes.
Fungal leaf spots
Poor airflow and overhead wetting invite leaf spotting. Improve ventilation, water at the base, and remove affected foliage promptly.
Winter loss
Frost kills the tender rhizome in colder zones. Lift after die-back, dry, and store cool and frost-free until spring replanting.
