The cold snap even had me holding my breath down here in North Florida. The forecast kept bouncing between 37 and 40, but woke up to 34 and soon as the sun started rising could see light frost in a few cold pockets around my place. Honestly less concerned for fruit loss, than I am ambrosia boring beetles being drawn to any stressed trees.
For the forum members anywhere between Florida and NC who did get hit, might want to proactively spray your tree trunks before it's too late. Once you see the sawdust toothpicks sticking out, not much of an option other than cutting them to the ground and hoping for the best on resprouting.
