I have propagated a cutting and want to know when to plant in ground. Instructions were to root the cutting in early fall. I have some roots, but it is middle of Sept. . . with frost coming soon. Do I put the rooted cutting in the ground before the frost, or keep it indoors all winter in a pot? Please advise.

I would simply pot it up and overwinter it indoors until spring.
