Well I hope to be able to help. I have been growing them for 20 years. Have never, had no flowers, in a season, have struck cuttings at 4 cms and have inarch grafted. The best thing about them is they flower on new growth. So you can prune them hard after flowering, and they will power away again.
One thing to remember is they are very apical dominant, so now is the time to make sure the apex is still tapering. This is where I have taken my cuttings from.
The important thing for flowering is to remember new wood. If you keep pruning for shape you will lose buds that will flower. So cut back hard now, even if it has not flowered. Let it grow , then in late March early April, cut to shape then do not I repeat do not prune again until after flowering. You can pinch tips for ramification, but that is it.
I use Miracle Gro for Azalea and Camellias once a month and use Phostrogen once a month. Alternating fortnightly. This is my standard fertilising regime. All my plants get this except the miracle Gro is not used on my exotics. I have some pictures of my tree in flower. Then when the blooms were past there peak and then the pruning, or cutting back.
Re potting is carried out now if it is needed. In most cases about every 3 years, some times it will push its self out of the pot. So it needs it so do it now the weather is starting to warm up. I will now go and look for some of the way I take cuttings, and if I have one which I am sure I do of re potting them.
