What temperature is too cold for potted plants?
The general rule of thumb is that most plants don’t grow if the temperature stays at 28f for five hours. When temperatures plummet below the freezing point of water, new leaves give up the ghost. Frost-freezing occurs when the air temperature drops below freezing for a period of at least three hours, and the temperature of the water in which the plant is growing drops to below 0° F. This is called a “freeze-thaw” period.
The plant will continue to grow, but it will not be as vigorous as it would have been if it had not been frozen. In fact, it may not even grow at all. If you freeze a plant, you will probably have to remove it from the refrigerator and let it thaw for several days before you can harvest it.
