First time starter of hellebore seedlings from seed (to be quite honest, a good friend sent me seeds which had developed roots and I potted them up and now they are producing top growth). Following is a picture of the seedlings.
My questions are when do you begin individually potting them up and when do you start putting them outside. I realize that hellebores are cold hardy but these have not been outside yet so will need to be hardened off. I guess the second part of the question is when do you know that the plants are sturdy enough to stand being outside so you don't have to worry about them freezing back and not coming back?
