I'd guess in your zone, and since many younger plants aren't nearly so cold hardy as more mature ones, it might be best in your somewhat marginal zone, to just delay the planting til spring , and mine here in Michigan do just fine all winter indoors, and never get planted out. Do keep in mind however, they'd prefer a spot on the cool side and also with good humidity and decent light.

i growe two camellias outside and i'd plant mine in spring . and i think its betetr you do it too

Thanks I figured spring would be the best time just wanted to make sure.
