Will one night of frost kill my plants?
Light frost typically doesn’t cause major damage, with exception to very tender plants, but hard frost freezes water in plant cells, causing dehydration and damage to cell walls. … As a result of these damaged cell walls, the plant defrosts too quickly, killing leaves and stems.
Does spraying plants with water prevent frost damage?
When water freezes and turns into ice, it releases latent heat. Then, the ice that builds up on the plant will insulate it from the colder surrounding air temperatures. Because of this, some growers choose to spray their crop with water before the freeze occurs.
Does watering protect plants from frost?
