Camelia flowering - lack of!
 

I have a camellia which seems reluctant to flower. Each year we get a few,
but nothing compared to others in my area.
It's planted quite close to a west facing fence, hence protected from early
morning sun, but I think the position may be a bit too dry?

What do others think? Or is there some trick to getting Camellias to flower.

Thanks
