ANSWER: Fruit with a dark brown discoloration on the skin has been attacked by citrus rust mites. Citrus rust mites, which are too tiny to be seen with the naked eye, just damage the skin. Fruit will often ripen normally, perhaps smaller, with the pulp and juice still good to eat.
How do you know when Satsumas are ready to pick?
When satsuma ripen, they become slightly soft. That’s a good indicator that they are ready to harvest. This softness makes them extremely easy to peel but poses a challenge when harvesting. If they are simply pulled off of the tree, some peel will be left on the tree and the fruit will be compromised.
