Hydrangea loves water - it roots even if you just stick the piece directly to water. You can do it too, because now is the time to propagate hydrangea macrophylla (mophead). 3 weeks ago I’ve cut a piece of fresh stem . Choose the stem that doesn’t send flowers this summer, just to prevent removing the flower. It’s always better to have flower and new hydrangea than new flower or new hydrangea – right? I’ve left the top pair of leaves, cut them by half to reduce the evaporation, place them in water and almost forgot about it. Very soon you will see first roots.
This time placing the cutting in the water was an experiment. I wanted to see the roots. Usually I just stick the cutting in the fresh potted soil, keep it in shaded place and make sure the soil is wet (I mean soggy wet) all the time. This method with Hydrangea macrophylla guarantees 99% success. I failed only once, when I tried to do it end of September, after obtaining exciting varieties.
I always propagate H. macrophylla in the summer, while propagating Hydrangea paniculata works best very in early spring, before vegetation starts.
