reddish sap on pine tree #328400

Asked June 03, 2016, 5:14 PM EDT

I'm attaching photos of a reddish, resin type sap on my pine tree. I think it's an Austrian pine. 

What should I do?

Thanks!

Expert Response

This is resin. It is produced in reaction to a wound, either from pruning or other physical injury, from an insect, or from a disease. It is a little hard for me to see which it is, though the second picture looks like it was taken from just below a pruning wound. No matter what, though, it is a good thing that the tree is trying to protect itself.
