Maybe one is rootstock. You'll need to make certain of that and then eliminate the rootstock shoot (if that is the case), because it won't bear fruit of any value.

Can you explain a bit more. I'm not familiar with growing from rootstock.

foo foo plants are grafted onto understock .;..

usually.. because they cant be rooted ... or are too slow in doing such ...

when the plant above is damaged .. or for other reasons ... the root stock can sucker ... or sometimes they do it for no reason ...

since the understock is chosen for its vigor ... it can usually outgrow the foo foo plant... and eventually take over ...

if you pull back the soil.. you can find out if they are attached ...

Looks like you are right! The tag says "betulaefolia" rootstock. I assume the tree with the tags is the fruit tree? How do you recommend I trim the rootstock tree without putting the fruit tree at risk? I was thinking I just cut it down a few inches above the split?
