My apologies, I read this wrong!! You can't take any photos. (Didn't have my glasses on.....my bad)
So here's the deal. Weeping cherries can be damaged easy. If you spray roundup, there's a high probability if you hit a shoot that grown up out of the ground that it will kill the tree. I know....from experience.
The weeping cherries are also latecomer in the spring, so I would wait a few more weeks and see what happens. You wouldn't have any leaves yet, probably just buds forming if anything.
