Q.Italian Stone Pine
We love our tree. We have cared for it for over 20 years now.
Do you think the bark on this tree looks normal? We had a tree specialist come over and he didn’t seem to know.
Thanks for your help.

I'm sorry but I can't give any information from this image. I would suggest speaking with your County Extension Office.

There are usually not many disease problems found with this species. You may see episodes of pine needle cast, which is a fungal disease that causes the needles to turn brownish-red and fall off. This is usually a symptom of other problems like bark beetles, so check the tree for other pests and diseases.
