I need free underneath Pine and Spruce that has lost all of their bottom limbs and no longer provide coverage and privacy. I was thinking about planting but heard there is an insect problem with them is this true? I also have old Hemlock that are beautiful what should I watch for so the older hemlocks do not become infected

It seems that many of our trees are under attack. Various pests and diseases seem to be on the upswing. Depending on the type of pine and spruce, rhizosphaera needle cast disease can be a problem:
