Feng Lu

Hi, Tereza,
I am in North California. I did find one small green worm on a leave in one low branch, however I did not find anything on other branches.
I sprayed neem oil ten days before, and seems not help much
Thanks,
Feng Lu

Thanks all.
I didn't find grasshoppers around the tree.  I am in North California,  bought and plant this tree this January.
There seems no good leaves left on all its branches. I pickuped four typical leaves and take a photo.

It seems my cherry tree is eaten by something, some leaves only have part of the stem left. However I did not find any insects for most of them.
