White pine needles

Asked September 23, 2019, 11:18 AM EDT

Why are so many white pine needles turning yellow and falling off? The ground under and around the tree is almost completely covered in needles. And in fact all the white pines in my complex are doing the same.

This is normal in white pine. Seasonal needle drop in white pine is when older, inner needles turn completely yellow and drop in fall. These needles should not have any spots.
