Q.Hibiscus black things on leaves
Hello I have brought a Hibiscus inside and since bringing it in I am binding these black things on the leaves. I have sprayed the leaves with soapy water thinking they were afids. They seem to come back in a couple days. Any recommendations?
Black aphids do often attack hibiscus, so you're probably right that that's what they are. Here are some articles that will provide some control options:
