Why are my older pine and spruce trees dropping their needles?
Rate This FAQ
If the needles have turned yellow then brown or reddish in color and have fallen from the tip of the branches back to the trunk, it may be damage caused by drought, insects or winter injury. The dropping of older needles near the center of the tree is a natural process. During summer, water trees deeply and infrequently. In early fall and winter, apply adequate water as needed. Keep trees healthy. Borers and beetles attack trees in stress and may cause early death.
