So many people don’t know how to prune trees … and not just Mexico … everywhere. I’m not sure this one has ever been cut back but how else could it turn into such a mess. There are good sized suckers coming up from the base of the tree and they will be the first to go … but looking at that tangle of branches I won’t know where to start.
Leaves are gone but still some fruit on the tree so will wait till it gets colder and sap stops running. No option other than looking up ‘Apple Tree Pruning for Dummies’ on the Internet
