<human>:  What is the best way to prune a lemon tree?
<bot>: The best way to prune a lemon tree is to remove any dead or infested branches, along with any branches that are rubbing against each other. Trim off any long or unruly branches, and make sure that the center of the tree is open, allowing air and light to reach the inner foliage. Taking off older, less productive branches and limbs will also help stimulate the growth of new, more productive branches. Lastly, keeping the height and width of the lemon tree to a manageable size with regular pruning will keep it healthy and productive.
