White pine: Can this tree be saved?
I've lost 3 white pines in 4 years. All approximately 20 years old, in sunny and dry locations. Needles turn brown from the stem to tip and drop. No signs of holes in trunk or beetles or other bugs. Here's the latest photo. The bottom third branches have all died. I would say the tree has lost about 50% of its needles in the past two years.

Here's another photo showing what happened last year to another pine in a different bed.
