Answer: Most weeping cherry trees are grafted, with a weeping top attached to an upright base. The new weeping growth will angle upward before it spreads and weeps, so what you are seeing might be normal. That is how the tree adds to its height over time.
On the other hand, sometimes there will be growth from below the graft or joint, and this is not normal. If the branch originates from below the graft and is from the trunk rather than above the graft from the weeping portion, it should be removed. Typically these will grow straight up and very fast. Cut it off cleanly leaving as little stub as possible. Keep an eye on the tree and whenever small buds or sprouts appear below the graft rub them off right away before they get big and steal significant energy from the plant. If not removed, they will eventually overwhelm the weeping portion. Good luck with your weeping cherry tree!
