Why are some of our oranges turning brown? I feed the trees pretty regular. This is the first year it has happened.

Check "citrus greening disease" I don't know if that's it but is has pretty much wiped out the Florida citrus industry.

From the extension service

The peel on some of my oranges has turned brown. What's wrong with them?
Rust Mite Feeding—Tiny rust mites feed on the peel during the summer causing a russeting of the peel. The interior quality of the fruit is not affected. Homeowners can ignore this.

That's another good possibility. My lemons are suffering from mites too, but mites can be controlled. It might be a good idea to take a sample to your local extension service to be sure.

Citrus trees are hosts to mites, scale, mealybugs, and now this new disease that is spreading from Fl. to Ca. so better to find out for sure. There no cure as yet for the disease but to remove the tree. Oh yeah, I forgot about the citrus leaf minor.
