Camellia buds turning brown and when buds open the flower petals fall off the plant. Why? Buds are multiple at each sight on the branch. When one opens, the flower petals fall off of the branch. In other locations, the buds turn brown. Plant is in very shaded area.
Based on the symptoms, I think you should check for the presence of bud mites, which can only be seen with a magnifying glass. If you detect mites, you should spray them directly with either horticultural oils or insecticidal soaps.
If you do not detect mites, then the bud drop could be due to over or under watering or a drastic change in temperature. These reasons and others are fully explained in the following article;

We planted two Camellia bushes last summer. This spring the bushes have not shown signs of growth. Some of the branches are brown, but some have a green color to them. Is there a chance that the bushes will put out later in the year? Should we put fertilizer on these? If so, what kind?
New plantings of Camellias need plenty of water to become established.
Your plants may not have survived the winter.
Most varieties are hardy to zone 7, with a few cultivators that are zone 6.
Check the branches, if they snap and break, they have died.
You can scratch the bark, if you see green, they are still alive.
Do not try to fertilize the shrubs into health.
Wait and watch for any signs of new growth.
Here is a link to refresh you on the care requirements.

I planted new plants in November. They had many blooms and flowered even after frost. I moved them to a shady area by my north facing front entryway. One of the plants has leaves that are staying green but are getting brittle and are dying. What's wrong? Thanks.
Camellia's that are in containers will need more protection against the cold temperatures.
The roots are more susceptible to freezing in containers then if they were planted in the ground.
Do the branches break and snap?
Scratch the bark--if you see green underneath, it is still alive.
Prune away the dead material and wait and see.

My camellia japonica plant didn't do well over the winter and is loaded with dry brown leaves and very few green ones. There are only 2 flowers and I usually have many, many more. Should I trim it back or leave it alone? Also, should it be fertilized and with what? Thanks so much for your help....I am really disappointed in what is usually a beautiful bush this time of year!
Here is an article on how to save cold damaged plants that will help you. The best thing you can do is prune the damaged parts away (after the danger of frost has passed), water and fertilize it.

Leaves still look dark green and shiny but have suddenly started to drop off plant. This year plant, which is in a large patio pot, has had many more flowers than last year and looked a picture!
I'm sorry your Camelia is dropping leaves! Is your plant getting a lot more sun than last year? It may be suffering from sunscald. Or if it has been repotted, the new soil may not be agreeing with it (Camelias need acidic soil and good drainage).

A Camellia will lose some leaves naturally each Spring. Look for signs of new leaves coming in.
Cold weather can also cause leaf drop.
Poor drainage can also starve the plants roots of oxygen, causing leaf drop.

Camellias can be very picky about their soil -- and as a result, they are picky about their fertilizer as well. You'll want to check the pH of your soil before adding anthing to it. This article may help you:
