I should also add a precaution in misting or wetting foliage. I presume it gets full sun on the west side for some period of time during the day. This can cause burns on the foliage remaining. Water droplets magnify uv rays. Did the tree recently recover from root rot or overwatering? Why are you refraining from watering it thoroughly?
