Eastern white pine (Pinus strobus) is one of the most economically valuable and ecologically important forest trees in the northeast. It is also an abundant landscape tree. In recent years, white pines in the region have exhibited symptoms of decline, which include: yellowing/browning needles, premature needle shedding, thinning canopies, undersized shoots and needles, resinosis, branch dieback and death.

Have you recently experienced premature acorn drop on oaks? While this can be caused by environmental stress, it is also possible that a tiny gall wasp is responsible. For more details, go to the INSECTS section of the August 9th Landscape Message.
