Dormancy

I live in Oklahoma, we have mild winters and long hot summers. It barely snows and if it does it’s 1 out of 365 days. In October the day temp is anywhere from 65°F to 75°F and night is 40-50. It will drop as we go into November/December but it will not get below 40 during the day until then. Is the fridge method better or should I put them outside and let nature handle it? This is my first dormancy, any tips or advice is welcome! Pics for attention.
