Pine Trees | Brown needles?
Hi, The change in interior needle color on your pine tree is normal for this time of year especially when the weather starts to change. You only need be concerned when it is the new growth or needles at the tips of the branches turning brown that there is a bigger concern. As pine trees grow and shade out the interior needles, the needles are no longer needed and cannot make food (without the sun) so the tree will shed these needles. Some years it is more noticeable than others.
