If your 'Kanjiro' is blooming, that tells me that the plant is basically sound, though still stressed from the beating it took from the polar vortex.

I don't know, but I do suspect that your camellia probably got zapped at a point when it was trying to put out its new spring leaves, and when it was already under stress from the prolonged cold temperatures. So even if it's still capable of leafing out all over, it may have been under too much stress to try, get zapped and then try again.

If it were me, I'd see what I could do to protect the plant from cold winds and/or unusually cold temps this winter, and then wait to see what sort of new leaf growth you get in the spring. If you then believe that much of the trunk/plant is dead, you should remove the dead wood.

I doubt you'll need to cut your camellia all the way down to the ground, but it would probably survive if you did. However, because camellias (even 'Kanjiro') grow slowly, I'd recommend cutting it back as little as possible. Concentrate on removing dead wood this season, and once you know how much of the plant is still healthy, you can prune according to what shape you want.

Yes, you can lose future blooms if you prune your plant after it begins to set the next season's buds, but don't be afraid of pruning for shape. Even if you're pruning a bit late and you lose some flowers the following season, it may be worth it if you have an attractive plant in the long run. 'Kanjiro' is a variety that responds unusually well to proper pruning, so decide what shape you'd like then cut accordingly.

Good luck,

Many thanks, Virginia. I will do just as you suggest.
