Last fall, one of my white pine trees turned a yellowish color and lost a lot more needles than usual. The other white pines nearby did a similar thing without the needle loss. The other white pines have recovered and are lush and green, but the original one appears to be dying, drying out, and showing more yellow. They are all approximately 10 years old. What can I do to save it?
It could be a root problem causing the decline of the one tree. White Pine are susceptible to root rot disease and/or the root collar could be buried causing vitality problems with this one individual plant. Treatment for root disease and fertilization may help if the tree is not too far gone.
