Q.Black On Blood Orange
Why do my blood oranges have a black on them? It washes off but not completely. It is the first time my 4 year old tree has grown fruit. I’m concerned to eat it and not sure if it is an issue and how to fix it.

It most likely is sooty mold and though unsightly, is not harmful in itself. And the fruit is safe to eat. However, it indicates you have an insect infestation. Read below how to manage the insects:
