Fruits and Nuts: Dwarf Julia mango tree problem?, 3 by Goalaso

It\'s about 10 years old, and really bloomed this year after some fertilizer was added. But it\'s still smallish (6-7ft), and seems to be tilted to one side. I took photos of the side not growing. Are those branches dead? There are also some spider-like webs on a few leaves, and one of the main trunks has this sharply delineated black area. Don\'t really know what\'s going, whether to expect fruit from all of these flowers, whether to stake down the tree, or trim it to shape it better, or if it\'s diseased...?
