Brown Spots on leaves of China Doll plant
The plant appears healthy except brown spots are appearing on of some of the leaves of our new China Doll plant (1-2 weeks). We plan on watering once a week and we have watered once. Is this a sign of too much water or not enough light? We have mini-blinds on our window that we keep closed during period of high heat or below 50 F. There is plenty of subdued lighting. The plant may get air movement from the ceiling fan and it is 12 ft from our patio door. We live in Arizona and keep our home at 82 F. in the summer and 75 F. in the winter.
