White Pine with Brown Needles

Asked March 13, 2015, 9:50 AM EDT

one of the six white pines in my back yard has all brown needles. They are sparse throughout. They fall off easy if you brush with your fingers. What is the cause? What is the solution?

White pines react poorly to wet sites and sites with compacted or heavy clay soils. They may perform well for many years, and then die in one season as a result of being planted in this type of a soil. Pines also shed their inner needles in the fall. It may appear that the tree is doing poorly but it is actually a natural event. You can read about white pine decline at http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/environmental/decline.aspx I suggest that you submit a sample to the UD Plant Diagnostic Clinic to learn if the condition is serious.
