The attached picture is of a tree that was not used for turpentine, but many of our other trees have been and some still have the “cat whiskers” embedded in them. Can you tell me what causes these vibrant colors? Also some of our trees appear to be slowly bleeding. These tree’s trunks are coated in sap towards the bottom and many time when we cut one, the sap inside ends up being green… Read more »
