How can I properly trim an avocado tree for optimal growth and fruit production?

To properly trim an avocado tree for optimal growth and fruit production, prune it during the late winter or early spring before new growth begins. Remove dead or diseased branches, as well as any crossing or crowded branches. Trim back the top of the tree to encourage lateral growth and shape the tree to allow sunlight to reach all parts. Avoid over-pruning, as this can reduce fruit production.
