Q. What is wrong with my orange tree? It has lots of oranges, but the tips of the trees are dying in some places.

A.
Your pictures look like either an insect or disease problem, both I have few
skills about. First, I would open the canopy of the tree a bit more by reaching
inside of it and pruning the limbs at a joint (where they come together) and
remove one of them to make the canopy of the tree more open. That will help air
circulation a critical factor for disease control. In some cases, it can remove
disease problems when humidity and air movement are factors.
Secondly, after the canopy is more open, I
would look at the damaged areas. If you bend the branches that remain you can
determine if it is an insect or disease problem. The insects will weaken the
branches just below the damaged areas and break. Diseases will not unless the
area is dead. Look for insect damage or disease problems just below the dead or
dying areas.
Sorry, but there may not be any chemicals of use. Just plant management or wait for a change in the weather.
