Question From: R. Ewoldsen - Linwood, Kansas, United States
Q: I have approx. a 40 ft white pine that looks healthy until you get up close, On the trunk from about 6ft off the ground to about 9 feet off the ground there is a lot of white sap, covers about 80% of the trunk in that location. Mixed in there is also a reddish/orange sap in several locations that looks like it has bubbled up away from the tree 1/4 to 1/2" as well as running down the trunk. There are numerous holes in the trunk with most being in straight line (woodpecker?) I have 2 other 30 ft tall pines, not white pines I am not sure what type, long needle, that have the same thing on the trunk but over more of the trunk. On one the needles are starting to change to orange starting from the end of the branches. I sprayed the trunks with an insectide but would appreciate help? Thanks in advance
A: If it were my tree I would get an onsite inspection from a certified arborist ASAP for an accurate ID of the tree's issues and recommendations for treatment. To find one in your area go to www.tcia.org and enter your zip code. Spraying any plant with a pesticide to control a mystery issue is a waste of product and can possibly do more harm than good. The pine tree may have a disease that causes cankers which drip sap. Best And Happy Yardening, Nancy
