My citrus trees have been pretty tolerant of the 30’s at night, But I was taking them in and back out on sub freezing nights but I think there going to remain indoors from here on out with temps now reaching the 50’s it’s staying in the 60-70F range in the Green House, My Lemon and my lime tree is blooming big time, I have 2-Washington Navels, 1-Myer Lemon and 1-Key Lime tree.
