Q.Sick Tropical Almond Tree (Terminalia Catappa)
I have a Tropical Almond Tree (Terminalia Catappa) on my property on the Southern Coast Ecuador. It is very sick. All the leaves are spotted, turning brown and falling. There is a large bruise on the trunk. It has been getting watered regularly. It recently (about 2 months ago) went through a period of shedding and regrowth. The regrowth (leaves) were very green and healthy. And then I noticed it was looking bad and has a large bruise on the trunk. I have no idea what to do and I am afraid the tree is dying.

It has likely contracted a disease from overwatering. This resembles many different fungal/bacterial infections.
I would treat with fungicide/bactericide, but do be aware that this kind of damage usually results in the loss of the tree.
