|Hydrangea macrophylla Cutting|
How to Propagate/Root a Hydrangea:
- Whenever you try to root cuttings make sure that your cutting tools are clean. You don't want to transfer diseases from another plant to your new hydrangea!
- First I take a softwood cutting with a couple nodes on it. I don't worry so much about the length of the cutting but if you keep at least two nodes you can be sure it will be long enough. I try to avoid flowering cuttings so I don't cut off any potential blooms.
- I remove all but two leaves. Some people leave 4 and trim back the leaves to avoid excessive moisture loss.
- Then I dab a little rooting hormone over the cut ends and a little bit of the stem.
- After that I place it in a moist rooting medium (i.e. sand) and continue to keep it moist. In about 10 days it will begin rooting.

Always keep in mind that you want to use a clean medium for your cuttings, keep sterile equipment for making the cuts, and take cuttings from disease free plants. If any one of those factors isn't present problems with rooting may occur.
This method works great for both lacecap and mophead hydrangeas (Hydrangea macrophylla) but other types of hydrangeas, like oak leaf (Hydrangea quercifolia) may need a slightly different treatment. I've found that oak leaf hydrangea is a little tricky sometimes to get rooted but it definitely can be done!
