Hydrangea Rooted – What Now?

Rooted hydrangea from the cuttings I took this summer.

That was the question one of our readers asked a few days ago. Evidently she had followed the instructions on the post “You Can Root Hydrangeas Now,” from July 31, 2016. In the picture of mine above, they are putting out young leaves, and this is often a sign they have rooted. Here is what I do. First, I keep the soil damp and do not try to transplant them until late fall or spring (I prefer spring) after the foliage appears. Since the cuttings were not “stuck” until the end of July, I like to wait at least 2 months before I fertilize them, and then I only do a light application of granular like 5-10-10 or a half strength application of liquid (I use liquid). I leave them in the containers they are rooted in and encourage them to grow until we have the first freeze that kills the foliage. Then I move the plants against a wall (not a north facing one) and mound soil around the pots and mulch the plant, pots, and all. If this is a dry location, I would water them in winter; otherwise, I leave them alone and either transplant them into the garden or allow them to continue to grow in their pots until they are the size you want to transplant. Remember, it might take several years to bloom, but they are a great summer flowering shrub for any garden.
