One of the most common questions we get here in the fall at Van Wilgen’s is, “Why are my pines turning yellow? Are they sick?” The answer is, thankfully, no. All trees and shrubs renew their foliage annually in the spring and summer and shed old, unneeded foliage in the fall. While this is most apparent on deciduous trees and shrubs, such as maples and hydrangeas, which shed the entirety of their foliage annually, evergreens like pines, spruces, and holly shed as well as a part of their regular life cycle. Most evergreens hold their needles or leaves for two to three years before shedding, so what you are seeing is actually evidence that your tree is growing, thriving, and aging normally.
