I hope someone can help me. I have a Weeping Cherry, or I should say was supposed to be a Weeping Cherry. It's been in the ground for 4-5 years and never gets any taller than 3-3 1/2'. The weeping branches grow like crazy and end up growing along the ground because the trunk of the tree never gets any taller. It has gotten a lot bigger around (5-6"), but not taller. After observing this very strange growth I took a really good look at it and I suspect the top has been grafted onto the trunk. Is there anything I can do about it other than just cut it down and start over? I hate to do that at this point, but I have to say it looks pretty strange. Thanks.
