Our cherry tree is about 15 years old and although it does not give fruit ( as it is not the proper climate here in Israel) we enjoy its beautiful leaves in the fall and the lovely cherry blossoms in the spring and the shade in the summer. This summer it is oozing sap all over- even on the higher branches it is simply dripping and dripping. One branch is actually dead and we have pruned it. I have enclosed some pictures. Can you help us ???
