Hello, I planted a bartlett pear tree this spring. It came in the mail as a grafted dormant tree. I am curious if the ways the new branches are growing are concerning or not? They are sprouting above the graft line so as I understand they aren't the root tree, but should be the pear tree growing. Is this normal for branches to grow from the bottom of the tree like this? Should I do anything to this or let it continue to grow as is? Thank you for the help!
