It may seem odd but ice itself sometimes can protect crops from frost! Some growers actually spray their crops with water on a freezing night. Water freezes quickly on the plant and then a strange thing happens. As long as ice stays wet, it can’s get colder than 32 degrees, a temperature many plant can stand. If the ice ever became entirely frozen and dry, it might drop many degrees lower, ruining the plants. But by continually spraying water on the ice, the growers keep it from going below 32 degrees even if the air is much colder. This may frustrate Jack Frost, but it saves the plants. This strange kind of" ice blanket "works only on plants that are strong enough to stand the weight of frozen spray.
