Blood orange tree

Question

I live in southwest Mississippi, and have a blood orange tree, it has produced fruit the size of a lemon or just little bigger, but it is not edible no red when cut open is this normal or what could I do too help them ripen the tree is over 7′ tall.

Answer 1

Oranges typically take 12 months to ripen on the tree. Perhaps they just need more time.

If the fruits have already been maturing 12 months, this could be a disease or perhaps a grafting issue. If there was a disease present, you would see other symptoms, like discoloration or mold on the surface of the fruits. If it is a grafted tree that produced good blood orange fruit previously, the rootstock could have taken over and started producing a different variety of fruit.
