Begonia 'Maori Haze' problems — and how to fix them

Begonia 'Maori Haze' (Begonia rex 'Maori Haze') 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.

Crispy brown leaf edges

Almost always a sign of air that is too dry. Raise humidity above 50% with a pebble tray or by grouping plants; keep away from radiators and cold draughts.

Powdery mildew

White powdery patches on leaves, common in high humidity with poor airflow and wet foliage. Improve air circulation, avoid wetting the leaves, and remove affected foliage promptly.

Leaf drop

Sudden loss of leaves usually stems from low humidity, cold stress, or root rot from overwatering. Stabilise warmth and humidity, and let the topsoil dry before watering again.

Faded or scorched variegation

Too much direct sun bleaches the silver-purple colour and burns the leaf surface. Move to bright, indirect light.

Root rot / yellowing wilt

Caused by soggy, poorly drained soil. Use a free-draining mix, never let the pot stand in water, and reduce watering frequency in winter.

Botrytis / fungal leaf spot

Grey mould or dark spots from cool, damp, stagnant conditions. Remove affected leaves, improve airflow, and keep water off the foliage.
