Staking new evergreen leader.Question: The tip of my jack Establish evergreen new leader.Training evergreen broken tip.pine, probably 5 years old, had been broken but not severed from the tree. It was hanging, still half attached. Is there some way to repair the tree tip so it can perhaps heal?

Answer: Coniferous trees such as pines and spruce are well known for their pyramidal shape. The reason for this unique growing form is the specialized growing point called the terminal bud. This is in the very top growth of the tree. Unfortunately, they often lose their central tips due to animal damage or storms. If a new central leader isn’t established a new shape takes form. Usually this is more shrub-like on younger trees or larger trees become shorter and more rounded in shape.

Should damage occur careful selection and remediation can provide a new leader and help restore the excurrent growth pattern. Details can be found in the pruning publication for mitigation options, Pruning Ornamental Trees and Shrubs, HO-4-W.
