A week ago our pines looked fine -- yesterday I noticed brown areas in the trees. Could you explain what might be happening & what I can do to stop more of the tree from turning brown?

Hi,
It's pretty hard for me to say without more information. What kind of pines are they? Are they too dry or in standing water? How old are they? Could you send a photo?

They are long needled pines so I believe they are Norway pines. They are about 15 years old. They are not in standing water and I don't believe they are too dry. They are in a low area of the yard and it usually gets pretty dewy in the mornings. I do not have a means to download a photo to you - Sorry. I usually water them in the Fall extensively and was talking about doing that last week when I noticed this.

Hi.
Thanks for providing some more info. I think maybe I will send you some links so that you can look at some photos and compare them to what you are seeing since you are unable to send photos. I didn't ask you where the browning is or starts and that does make a difference in trying to figure it out but you can determine what looks and sounds most like what you are seeing. Hope these are helpful.
