re: Ideas for fruit trees to grow in south Louisiana

satsumas are good down to 20 degrees, most other fruit trees can only handle 30 degrees

go with a Satsuma and expect anything else you plant to be something that requires being covered up and protected when the temps get below 30.

lemons and limes are good as well as grapefruits but it has to be something you eat as anything you plant will "at some point" yield a truckload of fruit so you better love eating them
