What About Frost?

Wind – even the slightest of breezes – can prevent frost. That’s because wind is like a spoon in your cup of tea: it stirs things around and brings down a lot of the warm air that often floats just above housetops and trees.

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 plants – and then a strange thing happens. As long as ice stays wet, it can’t get colder than 32 degrees, a temperature many plants 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 grower keep it from going below 32 degrees Fahrenheit 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. The system is used even to protect banana plants on some Central American plantations.
