Here in the northeast much of our landscape is dominated by white pines. These trees are valuable habitat, forest, and landscape trees. In recent years we've been seeing several diseases that cause the needles to become damaged and die off. While white pine can withstand a year or two of defoliation, subsequent defoliation will greatly decrease the trees overall health and will lead to larger more damaging problems.
How to combat the issues
To keep your white pines healthy and looking great we have a three point plan of protections: First, we fertilize in the spring to help the soft needles expand quickly through their vulnerable stage. Second, we begin fungicide applications to protect the outer surface of the needles. Third, a fall fertilization helps the tree put on woody mass so it can store more sugars for the following spring.
Keeping up on this trifecta of protection is the only way to help your pines. To have one of our certified arborists inspect your trees and offer a plan to keep them healthy, request a free consultation.
