Indoor shamrock (burgundy) has small brown spots on its leaves. It looks as though something dripped on it and left spots. On closer examination, it appears that the leaves have dried out in spots. This plant is 15 years old and I periodically repot. It's never had any problems at all and I have fed and watered it the same way for all these years. What could be the problem?
This could be a fungus. Treat the plant with fungicide, like neem oil, and see if this helps.
