Unhappy Camelia

I think they like ericaceous/acid soil, SC. I have a non-flowereing camellia as well, and I think it's down to the soil being too dry especially in the warmer months. I think they like good access to moisture (mine dried out a couple months after planting and has since recovered its leaves but not flowered). I haven't cracked my problem yet, so hopefully someone more successful will provide some insight.
