Impacts

Precautionary/preparedness actions

A hard freeze warning means sub-freezing temperatures are imminent or highly likely. These conditions will kill crops and other sensitive vegetation.

Protecting your plants

The Farmer’s Almanac recommends the following in preparation for freezing conditions:

If a frost is predicted, cover your plants, both to retain as much soil heat and moisture as possible and to protect them against strong winds, which can hasten drying and cooling.

You can use newspapers, baskets, tarps, straw and other materials to cover your plants. Cover the whole plant before sunset to trap any remaining heat. Be sure to anchor lightweight coverings to prevent them from blowing away.

Keep the soil moist by watering your plants the day a frost is predicted. Commercial fruit and vegetable growers leave sprinklers on all night to cover plants with water. As the water freezes, it releases heat, protecting the plants, even though they’re covered by ice.

To prevent damage, the sprinklers need to run continuously as long as temperatures remain below freezing.
