Norfolk Island pine tree
Why do some Norfolk Island pines have a split trunk? Mine grew 20 feet tall with one main trunk. At the 20 ft mark it decided to split in to two trunks. Why? Thanks, Bill

Norfolk Island Pine commonly will split trunks. They are susceptible to wind damage, which is often the cause of damage to these trees.
My research showed many reports of the tree splitting into two leaders.
