Happy New Year. We have a couple of questions for you. Has this problem been happening all year long and for many years? What kind of pine tree is it? Are the young needles at the tips falling off or just older needles. Please see this description for the Extension service at the University of Utah -

My Pine Tree is Losing its Needles

by Michael Kuhns, Extension Forestry Specialist

Have many of the needles on your pine tree have been dropping off lately?

Don't worry and don't cut the tree down! There is a perfectly natural explanation.

Though pines and most other conifers are called evergreens, their needles do not stay alive and green forever. Generally, new needles are produced every spring and summer and last for two to four or more years. So, as the tree grows larger year-by-year, newer needles are always at branch ends and older needles are farther back in the crown.

As needles age, they become less efficient at producing food for the tree. They also become more shaded by newer needles. For these reasons, old needles finally turn brown and drop off. This doesn't hurt the tree because several year's worth of newer needles are always there to replace the old ones.

Do be concerned, however, if your tree is losing needles at the branch tips. These needles are young and have not out-lived their usefulness. The culprit is probably some type of disease or insect.

So, if one-third to one-fourth of the needles on the inner parts of your evergreen tree are falling off, it is probably just a normal sign of aging. Just rake up the dead needles, or better yet, leave them under the tree for a good mulch.
