Generally, the water within the plant’s cells freeze, and that ice can injure cell membranes, ultimately killing the plant. Some vegetable plants will “bolt” during a freeze.
The freeze warning begins 11 p.m. Tuesday and lasts until 9 a.m. Wednesday, according to the NWS.
Row covers can reduce the drying effect of wind, and can provide a small amount of warming in a similar way to unheated cold frames, greenhouses and polytunnels, creating a microclimate for the plants. The first commercial-scale use of polyethylene row covers in the US was in the 1950s, and by the 1980s their use was widespread. [1]

Parisian market gardens in the 1800s used 18-inch diameter bell-shaped glass jars (cloches) to protect plants in cold weather. They were used to protect everything from young seedlings to mature plants. Notched wooden sticks were used to prop up and vent the jars on sunny days, and were placed back down on the soil before nightfall. [2]
According to the Old Farmer's Almanac, covering plants with a blanket or row cover — which can be found in garden stores — is the best way to protect sensitive vegetation, as the material ...
The ability to control intercellular ice formation during freezing is critical to the survival of freeze-tolerant plants. [3] If intracellular ice forms, it could be lethal to the plant when adhesion between cellular membranes and walls occur. The process of freezing tolerance through cold acclimation is a two-stage mechanism: [4]
