I just bought a mountain home and have lots of pine trees, that have been uncared for a long time. Based on my reading, what I should look for to help the tree grow and stay strong is : - Ensure there is one clear leader at the top ; - Prune dead and diseased branches ; - If some shoots come out of the trunk, cut them. Now my question, is that some of these trees overlap each other, or within a tree, several branches overlap and intertwine some. Is it a good idea to prune some of these branches, and allow the tree to focus its vitality in the branches that have more potential for growth ? Also, if smaller shoots come out of large branches closer to the trunk, should I prune these as well ? And if some needle bundle look weak and not too healthy, should I cut these too ? Thanks !
