I have two orange trees in my yard but the oranges always turn black before they turn all the way orange. What can I do to prevent this and get good ripe oranges?

This is likely a fungus. Are there any other symptoms on the tree, such as the leaves or the bark? This will better help us identify which one exactly is hurting your tree. In the meantime, I would treat the plant with a fungicide.
