We're having a few problems with our camellia at the moment so I'm keen for anyone to help identify the problem and offer any suggestions for how to fix it. If the problem can only be solved by using chemicals then so be it, but we would rather a more organic solution if one exists.

After finishing another magnificent seasonal flourish tender green leaves began to sprout in early spring. No sooner had they appeared then this brown began to invade them like a camellia bubonic plague. Now most of the plant is covered in these hideous brown spots and while the camellia doesn't appear to be dying nor leaves falling off, it certainly isn't looking like a picture of health.

It resides in a garden bed that receives mostly afternoon sun, if any at all, and has never suffered from this before. I initially diagnosed this as sunburn but after watching the sun's movement through the sky don't believe that this could be the reason.

C'mon all you camellia lovers...have your plants ever suffered from this before and how can it be rectified. I'd love to hear your comments.
