Calamondin Cold Snap Survival in Colorado

N. Colorado (NE Denver). 3 calamondins in pots indoors. Nice Sunday (70-85°F)—put on covered patio. Rained hard, snowed overnight (~1"). Husband thinks not below freezing. Will they die? Cold-hardiness?

Expert Advice

Citrus not cold-hardy but tolerate brief sub-freezing if not lingering (several days). Snow not problematic if fluffy not wet-freezing. Containers more susceptible (less root insulation). If leaves shed, don't panic—may be shock. Check cambium daily (scratch bark near base)—green = will regrow. If leaves shed, DON'T WATER—roots rot without leaves. Resume watering when new growth starts.
