When should I prune the limbs?
My tree is 3 years old and growing. It seems like I should cut off a couple of the bottom limbs so I could stand under it and so it will grow taller. Should I prune or leave it alone?
Promote a dominant central leader and prune for structural integrity. You can shorten lower branches, but leave some foliage to support photosynthesis and stability. Eventually you can remove these lower branches to achieve the clearance you need and desire.
