Deciduous tree leaves turn color in the fall and drop, but did you know that the needles on evergreens do also?
Although most conifer (cone bearing) trees are considered to be “evergreen,” their needles do not live forever.
They are considered evergreen because their leaves (needles) stay on the tree for more than one year before falling. New needles appear before the old ones change color and drop, so the tree is not bare.
Older needles on the inside of evergreen trees are shed each fall after they turn yellow, brown or reddish-tan in color. Some years, the colors are very subtle, but in years when the tree has experienced stressful conditions, the color may be more pronounced.
Pine trees can hold their needles for two to five years, depending on the species, while spruce drop only every five to seven years. The eastern white pine, which is very common in our area, drops its needles every two years.
So if you are seeing quite a bit of brownish coloration on your pine tree, it may just be the natural needle drop occurring. However, needle drop should be occurring only on the inner needles and not entire branches. If you see damage occurring on that level, check the branch for a canker or sore spot that may be effecting the growth.
