Why do my pine trees needles turn yellow and drop in the early fall?
Pines, Spruce, Firs, Arbs, Hemlocks, etc. are considered conifers (cone producing) and they all shed needles. Most commonly this occurs in late summer into fall. Needles tend to stay active and green on pines for up to three years then turn yellow and shed. This foliage is typically the inner most on the plant (the oldest). So long as the pattern is as such there is no need to worry.
