In one of my Japanese white pines, many of the needles even those that are green are dropping at the slightest touch, and then there are needles in some branches that are all browning but not dropping as easily. Unsure if they are two different issues.
I am located in San Francisco East Bay Area, Livermore, and we had some really hot days this summer, and I had kept this tree in shade, misted it often. Unsure if it inadvertently got over watered.
It was a beautiful tree, but now is suffering.
Please help saving it.
