How do I propagate a weeping red japanese maple tree in winter in Ky. Did it a couple years ago. Put outside too soon and they died. They started out rooting really well indoors. Don't remember exactly what I did. This time I looked online like last time and got conflicting directions. I know when I did it it was winter. All directions online now say propagate late spring or early summer. I'm pretty sure I took stem cuttings with buds on them. Removed lower buds. Put in water to moisten. then powdered rooting hormone and into potting mix in a clay pot wrapped in plastic and put where it got good defused light. Misted everyday and watered lightly as needed I think once a week. They did well. Took several weeks to root but I expected that. Didn't want them to die! I don't like it when any plant dies! I have rescued plants from garbage cans n the past. The mother tree is an excellent specimen!
