I'm in S. Florida and planted tree about 5 months ago. Some of the leaves are yellowish with black speckles and some of the ends of branches are black. Attaching a photo. Watered as advised. No fertilizer yet.

Sometimes, this can be of no fault to the gardener. Soil can be contaminated before planting. There are many things that you can do to combat soil pathogens, but I prefer a simple dusting of wettable sulfur and dolomitic lime.

This will treat the illness, but the dying leaves will not recover. They will fall off eventually. New growth will be unaffected and you will know the treatment is working.
