|I have a dwarf deciduous snow fountain weeping cheery tree. It is at least 10 years old. It started to develop red sap coming from the base of the tree trunk last year and weeps sap only in warm weather. It blooms every spring and looses leaves in the fall. What is this sap and why after so many years this started to happen? Any solutions, please advise.

|Cherry trees will exude sap from an injury. Weed whacker damage or lawn mower damage is common with landscape trees, but boring insects can also cause damage at the base of a cherry tree. Check for sawdust near the base of the tree or frass (insect poop). There's not much you can do to stop the sap. When the wound heals over, escaping sap should be minimal.
