Hi I grow a few Camellia plants in large pots as my garden soil is unsuitable being very alkaline. This year I have noticed the Camellia leaves have turned quite yellow. I think I remember reading somewhere that you can foliar feed Camellias with Epsom Salts to rectify this problem. I wonder if you can confirm this is true. Kind regards David
This could be a watering issue, nutrient problem or even pests or disease.

How do you treat this problem?
This can usually be corrected with neem oil, or peroxide, as long as it is just surface damage from powdery mildew. If the leaves are turning necrotic, then it is likely a more vigorous infection that will not be cured.

My potted camellia never really got used to her new environment in Greece and then came the hot days and aphids appeared. I used some dish soap with rubbing alcohol to exterminate them, but I probably overdid it. For the past 10 days leaves keep falling and most of them seem to have these red dots on them. Remaining leaves don't look as fresh as they used and even the shining ones look like they are maybe shagging. Any idea what these red dots are? Could they be a reaction to the dish soap or are they something else? I have tried cleaning the leaves by spraying clean water already. Is there anything else I can do?
I think the spotting is Aphid damage; if you still see live Aphids try spraying them off with water.
I would suggest Neem Oil as a good treatment for any further pest issues.
Support it's growth and it should recover.

My camilia plant is not very big and only a year old. It is not happy where it is so I wondered if it can be moved now in June. I can't see any buds on it and the leaves don't look happy. It gets full sun so I know this is a wrong location for it. What should I do.
It will be risky to move them, but if you would like to try, then it will be best to do so when it is not actively growing, or hasn't done much in a few weeks. It may be more likely that they just need a little extra care, or something to acidify the soil in the area.

WHAT difference will a picture make
Camellias are best transplanted in late winter or early spring when they are dormant.

The bush was planted a year ago. It has plants surrounding it. It has buds on it, but it does not look healthy at all, because of the yellow leaves. It is about 80 cm high.
This is usually the case with pH being too high, or underfeeding. Usually it is the first case, though.
This can be lowered with iron or sulfur. Follow all package instructions after testing the pH of your soil.
