I had a camellia bush that was about 5 1/2 feet tall in my yard of a rental house that I own. The tenant cut it back to about 1 foot tall, with just a stub remaining. Has this killed my plant? I don't know if it has bloomed or not for this season.
Generally, they cannot handle being pruned back more than a third of their height. However, it is still possible. Unfortunately, you will just have to wait it out, and if it survived, it should soon start showing signs of regrowth.

Please help. My camellia's leaves have got black soot like powder on them. You can scape it off and the leaf looks fine, but this black soot is taken over nearly all the plant. I have never had or seen anything like this.
This is sooty mold. It is a byproduct of a pest infestation, likely aphids or scale. This article will help you with getting rid of it: https://www.gardeningknowhow.com/ornamental/flowers/camellia/sooty-mold-on-camellia.htm
I want to dig up/remove totally a Camellia. It is about 6 ft tall and the stem is about the circumference of a scaffold pole. Do these plants have extensive roots?
You don't say if you want to transplant the camellia, or simply get rid of it. If you want to move it, this article has a lot of good information: http://www.aces.edu/counties/StClair/documents/NRCamelliaMoveGlover09.pdf
If you want to totally get rid of it, consider that many people love camellias. You could contact some nearby nurseries or landscapers, or run an ad, to see if anyone would like to have it. You could probably even offer it for sale. This way, you don't even have to go to the work to dig up the plant, and someone else still gets to enjoy it.
My camellia has a powdery black deposit on some of its leaves. It also appears to drop its flowers too readily. It is a mature plant, about 20 years old, and otherwise appears to be happy. Can you advise please?
This is called sooty mold, which more often than not is brought about by some type of pest, like aphid or mealybug. I would recommend neem oil. We have found it to be very effective against these kinds of pests and will also help treat the sooty mold.

My camellia has a profusion of buds which have never flowered this year. The leaves are now turning brown and limp. It has rained constantly for the past 10 days and prior to this I did water with a fertilizer to try and stimulate the flowers. Now it looks as though it is dying. Suggestions please.
It could be suffering from over watering or it could have a fungus (brought on by the excess moisture). There is not much you can do if the issue is overwatering as it was brought on by heavy rainfall and the soil not being able to take the water away quick enough. But, if the rain stops and the water drains from the soil quickly, the plant should recover. As a precaution, I would also recommend treating for a fungus. This can cause these symptoms as well. A general fungicide would be all you would need to do this.
I have a large (8'x8') camellia that I need to lightly prune to keep its shape. I have read that I should prune straight after flowering, which is about now for mine, as most of the flowers have dropped and the remaining ones are browning. The problem is, there are already what appear to be buds present next to the flowers. Have I left it too late or can I still prune without compromising the next lot of flowers? Andy
Many thanks

The little buds you see would be leaf buds.
Should Camellia be cut back? -If so, when?
