Troubleshooting
Begonia 'Fiestas' problems — and how to fix them
Begonia 'Fiestas' (Begonia 'Fiestas') 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.
Legginess
Stems grow bare and tall without pruning or in low light. Pinch tips and prune hard in spring to encourage branching and a fuller shape.
Powdery mildew
White-grey coating on leaves in humid, stagnant air. Improve airflow, keep foliage dry, and remove affected leaves.
Root rot from overwatering
Yellowing, wilting, and soft stem bases indicate soggy soil. Let the top few centimetres dry between waterings and ensure the pot drains well.
Leaf scorch
Bleached or browned patches from excess direct sun. Move to bright indirect light, shielding from intense midday rays.
