How to Prune an Avocado Tree. The avocado as a houseplant shouldnât be treated any differently than those grown outdoors, so pruning avocado trees indoors is no different. If you want to trim back the height, trim the tallest branch off the tree. The following year, trim the next tallest, and so on.When it comes to the width of the tree, start with the longest, most unruly branch first and work your way in each year with another branch.
