Why Do Evergreens Lose Their Needles

Sometimes when you come out to tag your tree early, you’ll see some brown needles on the trees. That’s because evergreens, like pine, spruce, fir and concolor, naturally shed their needles every two years in the fall season.

The oldest needles on the trees are cast off. These needles are generally located on the inside of the tree, closest to the trunk. The needles drop below the tree to provide valuable mulch or scatter into the lawn when the wind is blowing.

Here’s a link to a great article about this phenomena.
