Pine Needle Drop in Fall: Normal Seasonal Shedding

Pines are semi-evergreen; individual needles live 2–4 years. Older, shaded needles turn brown and drop in fall, sometimes in large numbers. This is normal. If an entire branch browns from tip to base, that signals a problem. Otherwise, no action needed.
