Pine trees browning
Hello and thanks again for your help. My pine trees are starting to turn yellow and brown. I live in Maryland and it’s been an especially soggy summer if that means anything. I have 13 and they are all starting to do it. Should I add fertilizer?

The most common cause of brown pine needles occurs in the fall and is normal. Pines shed older needles similarly to other trees’ fall foliage drop. The needle drop may be impressive in a large healthy tree. These needles make great mulch.
