Begonia 'Pin Up Flame' (Begonia × tuberhybrida 'Pin Up Flame') 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.

White dusty film on leaves in still, humid, crowded sites. Space plants, improve airflow and keep foliage dry.
Petal and flower scorch
Direct hot afternoon sun marks and crisps the bicolour blooms. Site in partial or dappled shade.
