Frost can severely damage outdoor potted plants, especially those with exposed roots. Without proper protection, plants may experience wilting, breakage, or even death. Heavy blankets or towels should be avoided as they can damage foliage, and plastic sheeting must be removed in the morning to prevent heat damage. Watering plants before a freeze can help retain soil warmth, but overwatering should be avoided, particularly in heavy soils where water may accumulate around the roots.
