We are currently receiving oranges which are experiencing "Citrus Greening."  This happens to Citrus fruits that are grown closer to the equator and are experiencing warmer weather.  It is cold night-time temperatures that cause oranges to turn orange.  There has been warm nights in Florida (where our oranges are currently coming from), so the fruit has not changed color on the outside. It is still as sweet and juicy on the inside. For more information, check out this short article on Citrus Greening
