Question:
I have a large oak tree leaking sap about a foot above the ground. The sap turns into a white foam like appearance. I dug away some of the bark in the area and covered the area with black prunning paint. The sap continues to leak.


Replies:
It will eventually stop but since it is still the growing season it will probably take some time.
