My 10 year old Monkey Puzzle Tree has large quantities of sap coming out of one side of the trunk about a foot above the ground. The tree has not been injured or pruned on that side. I noticed that several other posts to this forum mentioned a sap problem on trees that also had branches turning brown. All of the branches on my tree look fine. The responses to the other posts didn't address the sap. Is this normal behaviour for this tree or should I be concerned?
