Take cuttings in late spring or early summer when hydrangeas are actively growing for best success.
Choose non-flowering stems about 4–6 inches long, cutting just below a leaf node for optimal rooting.
Remove lower leaves and trim large upper ones in half to reduce water loss and stress on the cutting.
Dip the stem in rooting hormone powder to increase root development and prevent rot.
Plant cuttings in moist, well-draining potting mix, using small containers with good air circulation.
Cover pots with a plastic bag or dome to maintain humidity while roots develop—avoid direct sunlight.
Expect roots within 3–4 weeks; gently tug to feel resistance, then transplant to the garden once established.
