Yellowing Evergreen

Despite being “evergreens” the pine needles do turn colors and drop, they just don’t do it all at once. Right now, from a distance, the row of pines in back have a yellowish-green hue and are leaving a blanket of brown needles on the ground beneath them. Eventually, about a third of the needles will drop off of each tree. Then they’ll be green again for the winter, though much thinner, until spring.
