Answer: You can use a propagation method called layering to start new climbing hydrangeas. Simply find a stem that you can bend down to lay on the ground; nick the underneath of the stem and hold the wound open with a toothpick; cover that portion of the stem with soil and weight it down with a stone. Over the summer the wounded area will develop roots. Next spring you can sever the rooted stem from the parent plant and pot it up on its own. Best wishes with your project!
