Fab! I saw them in Morrison’s the other day and I’m not sure I’m going to be able to stop myself... As Urszula says and also make sure it isn’t going to get early morning sun (ie don’t plant east facing) or the buds will be damaged after frosts by thawing too quickly @ublaszko
You can feed it and prune it after flowering when you see the new foliage appear. Best to prune camellias while they're young to control their size. They can be pruned when mature but it takes them longer to recover.
