After doing a little bit more research, I'm wondering if my High Fragrance camellia might have the terrible Sudden Oak Death disease?

The symptoms include browning/drying of the tips and edges of the leaves, followed by dropping of the leaves as well as limb dieback.

If in deed this is what it has, then I would need to get rid of the plant ASAP!

Any comments?

Here is a link that might be useful: sudden oak disease- affects camellias

There's a lot of things that it could be. Sudden Oak Death is not likely one of them. Very few camellias die from it, from what I understand, they just tend to be carriers. If I had to take a wild guess, I would say it was root or soil related.

Some likely problems could be:

Potting too deep - camellias are shallow rooted and should not be planted too deep - sometimes even 2-3" below surface could cause problems.

Using a commercial bagged potting soil or soil that doesn't drain well can cause root-rot or poor root development. Commercial bagged potting mixes also have a lot of peat which hold a lot of water. Also sitting it in a saucer without draining the water could do the same thing.

Periods of excessive dryness coupled with cold weather could cause the problem as well.

Check the bark - scratch the bark with your fingernail. If it is green, you have a chance at saving it.

I would cut back any dead limbs until you get to green bark.

Check the planting depth and the soil - if you did use commercial bagged potting soil, you might want to repot.

If all you have access to is potting soil or mix, then you can use 1/2 potting mix and 1/2 perlite to add more drainage to the soil

Keep the top of the plant root-ball near the surface of the container - don't plant too deeply. Also empty any saucers after they drain.

Miracle Grow makes a transpant or quick-start fertilizer. I would use that to help it overcome whatever stresses it might have and to get those roots growing.
