Don’t panic if you see the inner needles of your evergreen turning yellow and dropping. It is a natural occurrence for evergreens to drop their needles in fall. For example, pines may keep their needles for three years and then drop them but it will vary from tree to tree and year to year. They may drop a few needles at a time or all at once. This is the way of a tree feeding itself as the needles will break down and add organic matter to the soil.
