I HAVE A SMALL JAPANESE MAPLE TREE AND IT HAS A GREEN JAPANESE MAPLE GROWING WITH IT ON THE SAM TRUNK.

Question

I WANTED TO KNOW IF I CAN SEPERATE THEM,BECAUSE THE GREEN ONE SEAMS TO BE TAKING OVER THE RED ONE.

Answer 1

Keep all instances of the root stock cut! If you allow the green shoots from the rootstock to take over, it will kill your top scion. You will need to figure out what stress is causing it to revert, in order for it to stop doing so.

Here are some articles that will help:
