Q.I Have A Flowering Cherry Tree In My Garden And Have Noticed That The Trunk Bark Has ‘split’ And There Is An Amber Liquid Coning
out The tree has been in situ for approx. 25 years with no problems in fact this year when it flowered it gave the best display it has ever had. Someone has suggested applying a ‘mulch’ around the base of the tree but can you suggest any other courses of action as I don’t want to lose the tree if possible.I think that it could be a ‘ pathagen ‘ but I really have no idea any assistance will be gratefully appreciated.
Gummosis: that "amber liquid" is sap and normally, you have to wait for the tree to heal but look for signs of borer insects:
