Satsumas are a newly popular citrus crop which is being planted in south Georgia in increasing numbers.  Unlike other citrus trees, satsumas need some cold weather to become sweet, and do very well in the Zone 8b climate in south Georgia.  Satsumas are similar to Cuties and are delicious and easy to peel.  About 25 acres, or 3000 individual trees, have been planted in the past year, and more are expected to be planted next year, according to Growing Georgia.  Satsuma trees are resistant to frost down to about 15F, but farmers often use a freeze protection system to protect their most vulnerable young trees.  For more information, click here.
