Answer: This plant naturally turns brown and dries up and rests after blooming, so if your plant has already bloomed you are seeing may be the normal response to the warmer summer weather. If you suspect it is a pest or disease problem, it might be a leafspot disease called shamrock chlorotic leaf spot. Unfortunately, there is no cure for that. It is difficult to make a diagnosis long distance. You may want to consult with your local county extension to obtain a more specific diagnosis and based on knowing that, decide what to do. If a chemical control is needed they will have the most up to date information on what to use and how/when is best to use it for maximum results.
