I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Watch to make sure you are not overwatering. Feel the soil a few inches down below the surface to see if it is wet or not before watering again. The frequent wetting of the plant's foliage may also be contributing to its problems. Those plants are not long lived in your hot climate.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
