Your tree is made of many parts but the main piece is your trunk! We cut and grind the tip of a hardwood dowel and mark each one for you for branch placement, so your ready to go when you get your order! Our hardwood dowels start at 6in and go up to a 24in! When you are planning your trees an inch or two of the dowel will be in your base. But you will be adding 3-5in in height with your top center branch.
