The pine beetles are responsible for attacking pine trees from the inside out. If you notice tiny holes or sawdust around your tree, it is under siege from this pest. It is important to address this pest quickly so as to not only save the tree, but save any nearby evergreens from infection as well. These pests can be aggressive, but are easily treated.
If you notice a lot of bulges that are leaking sap on your evergreen, this can be a sign of cytospora canker disease. White sap leakage and needle death are common symptoms of this disease and you should therefore contact a Tree Service in Laconia NH.
