Have read what you said about sap on a weeping cherry tree. Pretty sure mine is caused by whacky weather the last two winters. Would like to clean it off before wrapping for next winter. What should I use?
Sap on a Weeping Cherry Tree
Certified GKH Gardening Expert
I am rather reluctant to recommend removing sap stains from a tree because it has the potential to inflict damage and is nearly impossible to remove completely. However, in my research, I did find recommendations (see below link) to carefully scrape and chisel off tree sap, being very careful not to gouge the bark underneath it.
