Begonia U-377 problems — and how to fix them
Begonia U-377 (Begonia rajah) 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.
Crisping leaf edges
The classic sign of insufficient humidity; this species needs terrarium-level moisture to keep its bullate leaves intact.
Sudden leaf drop
Triggered by drying out, cold draughts or a sharp humidity drop; keep moisture, warmth and humidity stable.
Rhizome rot
From overly wet, poorly aerated mix; use a chunky airy medium and avoid standing water around the crown.
Powdery mildew / botrytis
Stagnant air in closed setups breeds fungal spotting; provide gentle airflow even inside a terrarium.
