Pest

Question

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.

Answer 1

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
