My Camelias have black spots on their leaves.
What is this & what do I do ? Can any one help ? .....Iris

Flower blight causes brown spots on the petals and deformed flowers, though it won't kill the shrub.

Camellias require a humid, temperate climate to thrive. They are fairly hardy and easy to grow, being able to withstand temperatures as low as 0º F, though some thought should be put into deciding the place where your shrubs are to be placed. Camellias need high temperatures and long days in order to develop their flower buds. However, for them to open, cool temperatures and short days are required. Flower buds will most likely be damaged if they become frozen and thaw rapidly, which will most likely happen if they are grown facing east where the morning sun will quickly thaw them. They should be placed in filtered shade. Generally, the warmer the climate, the less direct sun is needed. In climates where Camellias are not hardy, they can be grown in greenhouses with a minimum temperature of 45º to 55º F.

Except that it doesn't answer the question.

My reply to your earlier post:

Probably just a superficial sooty mould. This grows on the sticky
deposits (honeydew) that drips onto the leaves from aphids on the
under sides of leaves further up. Not in itself harmful, but do a
general check for aphids or other sap-sucking insects and take
appropriate action. A soapy-water spray is quite effective. The mould
can usually be wiped away with a damp cloth if you really want to.

but it does describe some of the symptoms that my camelia is suffering
(browned off flowers and buds as well as black spots on some leaves).

could it have been frost damage (though we're in Twickenham and can't
remember having particularly harsh frosts this year)?

Any course of action to take? Would it do any harm to give it a feed using
an ericacious plant food?
