We planted this weeping cherry tree in the spring and it did very well at first. However, once the japanese beetles came; they devoured much of the foliage until we got rid of them with Sevin and the beetle bags. The second picture shows that the foliage still has not recovered (didn't really grow back). We are hoping that it will generate new foliage in the spring. However, recently we noticed a lot of sap (first picture) is dripping from the tree and even collecting on the ground. I don't know if there is a wound underneath but clearly something happened to damage it. Should I try to clean the sap off and then try to put something over the wound? As usual, any info or suggestions that anyone can provide will be deeply appreciated

It's called Gummosis, It's a symptom of tree stress. Do you see any 'sawdust' mixed into the sap?

It can be caused by insect infestation, mechanical injury, or infectious disease and the damage has probably formed a canker.

A canker is a necrotic, often sunken lesion on a stem, branch, or twig of a plant. If you carefully scrape away the gum and probe the bark beneath, you will find the bark loose and the tissue beneath discolored. Clean the gum away with a sterile knife but do not dig too deeply, then treat with a copper fungicide, available at most lawn and garden stores. Read and follow label instructions.

Keep the tree well watered, watering once a month through the winter, then see how it looks in the spring. It may recover if there is physical damage which is not too extensive.

Good luck.

Here we scrape it off then give the infected spot a quick scorch with a propane torch.

Bet that will work Sunny. I'd try that first.
