Suggestions to save my camellias?

It appears you have a extreme fungus situation.Use a systemic fungicide and see if that helps.Do not do anything else until it recuperates.Have you had varying temperatures a lot of moisture????

Call your local camellia society and their expertise will amaze you! Also don't forget to clean your tools before working on them and clean again with alcohol before using on other plants.

looks to be a virus.. read this article: http://www.clemson.edu/extension/hgic/pests/plant_pests/shrubs/hgic2053.html

This is camellia blight. Pull every affected leave off the plant, put them in a garbage bag and get rid of them. If you just drop them on the ground and leave them, it will spread the disease. I have to do this to my camillias every season but once all the diseased leaves are removed, they don't return until the next season.

This is a fungus/gall. You need to remove all infected leaves/branches and toss in garbage can so spores don't spread. The camellia probably needs a good pruning to allow air flow through branches, which is part of the problem as moisture loves misery. You can drastically prune camellia and it will thank you. I had to cut one of mine back to about nothing and at end of growing season it is flourishing.

To avoid any & all diseases always pick up & remove all spent flowers. this is mostly what is causing trouble. Its work, yes. but necessary. Keep the ground under the plants clean. By this I mean rake up fallen flowers & leaves.

Camelia's recover very quickly from a major hair cut. If all else fails I would cut off all of the infected sections and burn the cuttings and all plant matter on the ground or get them off your property via your waste disposal. Then see if your tree recovers by growing new healthy growth. If not then I would say removing all the tree and any leaf matter in the area and starting again.

Yes, I neglected to say to put it in a baggie, I always do this.

Let me restate myself, take it to the local feed and garden store in a ziplock baggie, I am sorry Melissa I neglected to say to put it in a baggie. I sent the maintenance thing not because you need the maintenance to solve your current issue, but I thought that it might be helpful in the long run. Sorry Melissa if I confused the issue. Good luck with what is going on with it, very pretty.
