Q. Why do my pine tree needles turn brown in fall?

Answer

It's natural for pine tree needles to turn brown in fall. Although most conifers do stay green all year, most people do not realize that evergreens don’t keep all their needles all the time. Just when the oak trees lose their leaves, most evergreens also drop needles — but not all of them. While an oak tree grows all new leaves every year, most conifers grow a new tuft of needles on each branch, to add to the several years' worth of needles it still has. Each year in the fall, it loses the oldest needles (those closest to the trunk). This normal phenomenon is called seasonal needle loss or fall needle drop.
