This is a cutting that was rooted in the fall of 2015.

Every year at the end of July or first of August, when the flowers on the big colorful hydrangeas begin to fade, I attempt to root some of my favorites from my garden (remember do not propagate patented ones). I generally have about an 80% success rate following the step by step procedure illustrated above. Once they are potted put the pots with the cuttings in a shady, cool (if that is possible) spot. I lightly water them each day. If you can mist them, that is even better. In about 6 weeks you should know which plants are growing and rooted and which are dying. Do not fertilize until early October, and I sprinkle about a half of tablespoon on each pot of something like 15-0-15 and water in well. As winter approaches, I heel (mound soil around) the pots in a protected area preferbaly next to a structure. Most years I have blooms the following summer on the young plants.

  1. We have successfully rooted our hydrangeas. Now, what do we do with them over winter? Do we keep them in the pots and bury them next to a structure, or do we remove from pots, place in ground next to a structure? We will fertilize when putting them in ground?

    • Wait at least another month before you fertilize them then apply it lightly. What I do for winter is place them near a structure in the pots and heel soil around the pots then mulch potted plants. Plant next spring or let them continue to grow in the pots until they get bigger then plant where desired.

  2. Thanks for tip… Will give it a try!! My absolute favorite one is Nikko Blue. Can never have too many!👍👍

  3. I have just started rooting some flowers, so glad you put this one up, I had no idea how to proceed with the hydrangeas. Thank you.
