We moved all the peppers into the house in anticipation for 31 degree temperatures (almost unheard of in Florida this early). I covered what I could but our garden is probably toast.
Over the years, I have learned that I cannot put out my pepper plants early in the year. Cold weather can stunt their growth for the entire year. Better to wait until a couple weeks after the last frost date to put them out in the ground. Where I live in zone 3b, that means mid-June for transplanting the pepper plants outside.
Hope you did not lose everything. Good luck.
