Hi I often move shrubs and roses and have even moved a 4mt Fig tree in the Summer here in Brisbane and all have survived. I have moved Sasanqua camellias but not a Japonica if you did all the right things before you dug it up it should survive did you prune it by 1/3 to compensate for root loss

Camellia love a slightly acidic soil, pH between 5-6 they like moist soil but not wet soil so do not over water, you could be killing it with kindness if its two months I would stop feeding it with Seasol. Leaf drop is caused by either over or under watering.

Hubby and I dug up and cut down a 3mt Red Frangipani so we could work on the site for our new tank that was five weeks ago and last week it was sprouting new leaves on the bare 60cms high stems, of course that shrub is nothing like a Camellia I am just telling you so you can get a idea of how long .. Good luck with your two plants..
