I planted a tree in my front yard, I just noticed ANOTHER tree is growing out of the same area where I planted

Question

I planted a tree in my front yard, I just noticed ANOTHER tree is growing out of one of the branches of my old tree which is around two years old, and this happening very recently. The branch yields completly different leave as of my original tree.

Maybe it isn't another tree, but one of the branches is yielding completly different plants, and it overshadowing the leave of my old tree. How is this possible? Is this common or rare?

Answer 1

Depends on what kind of tree. Most flowering trees are grafted, which means they take roots  from one tree and the top of another and grow them together to get a stronger nicer tree.  If it's something like a weeping cherry, they do tend to send off limbs that may stick straight up while all the others are weeping. You can cut the odd shoot off as close to the trunk as you can get as long as it's no thicker than your pinky. If it's thicker than that wait till the tree is dormant in the winter then do it.  Either way the shoot isn't going to do any harm.
