Remove the lower leaves, dip the cut ends in rooting hormone, and plant the cuttings in well-draining medium.
Provide the cuttings with consistent moisture and warmth until they develop roots, then transplant them into individual containers.

Division

Divide mature bigleaf hydrangea plants in early spring before new growth emerges to create new, genetically identical specimens.
Carefully lift the plant from the ground, and use a sharp, clean knife to separate the root ball into sections, ensuring that each division has several stems and a healthy root system.
