The amount of photosynthesis happening is determined by the amount of sun reaching the leaves other than the number of leaves the tree has. If your tree has many leaves that are hidden from the sun by higher branches, then the process is diminished. Pruning the unnecessary branches enables the tree to get more sunlight, hence increasing the amount of photosynthesis. In the long run, pruning helps improve the overall health of the tree.
