trees are sick
I have several Ponderosa Pines. One is turning a pale olive/greenish color. It is about 10 feet tall and has been there for 8 years. The needles are still supple. The others are a nice deep green color. All get the same amount of water and food. Is it sick? What to do?

Do you see any other symptoms on the branches or trunk? It is hard to say what it could be with this amount of information.
I would suggest contacting an arborist certified by the ISA. There is a link below where you can look for arborists in our area, we have quite a few.
