rooting sky vine and where the heck do I buy rooting powder?
New gardener here. I've been doing this for about one year now.
I'm really getting tired of paying big bucks for every plant and would like to try rooting.
At the moment, I would very much like to root sky vine, and second maybe large yellow allamanda vine/bush. Can either of these be rooted by simply cutting off a part (which part?) and placing in good potting soil?
If not, or even if so, where can I buy rooting powder? Please don't say mix peat moss with sand or something . . . I don't even know what peat moss is!! :) I need something that I can purchase by name from a home improvement store or local nursery.
Thanks very much!
