I don't seem to have success with cuttings. I had 3 cuttings of bigleaf hydrangeas and 2 died already. The last one does not very well. It could be any these reasons, over water, expose to sun too early (I brought it out to the sun (2-3 hrs a day) after 2 weeks in shade).

I need to propagate bigleaf hydrangeas and Dragon Wing Begonia. Do you have any tips to enhance the cuttings' survival rate? Thanks

Take cuttings, plant in rich soil with more shade than sun (but not dense shade). They root all along the stem so no worries about cutting above or below a node. Keep moist but not wet.

Here are mine and you can see how nicely they root. All are huge hydrangeas now.
