We have an avocado tree that is about 20 to 25 feet tall. We want to prune it so it is not so tall. Also, it is wide and we want to condense the area. How much can I trim at a time without hurting the tree? We lost 2 large limbs that had over 500 avocados that were 2 to 3 inches big already. We know there was too much weight for the limbs. We have now braced some of the dropping limbs. How should we go about trimming our tree? And when should we trim our tree? It is a Hass variety that is loaded with fruit and the branches start at about 5 to6 feet off the ground.
