<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 diseased branches, thin out any overcrowded limbs, and trim branches that are growing in an undesirable direction. Make sure to cut at an angle away from the center of the tree and avoid making cuts too close to the trunk. Also, consider removing any low-hanging branches to make it easier to access the fruit.
