When to worry
A few small spots are manageable, but if they cover most of the foliage, the plant needs immediate attention. Normal aging may cause a single leaf to develop a small brown mark.
Stopping it coming back
Water at the base of the plant rather than over the leaves to keep the foliage dry.
