Frost Advisory: Protect Your Plants and Property from Icy Temperatures

A frost advisory has been issued for our area, indicating the potential for sub-freezing temperatures and the formation of frost on exposed surfaces. This advisory is typically issued when temperatures are expected to drop between 33°F (0.6°C) and 36°F (2.2°C). While frost is not as severe as a freeze, it can still cause significant damage to sensitive plants and outdoor equipment.

Understanding Frost Advisories

Frost advisories are issued by the National Weather Service (NWS) when conditions are favorable for frost development. These conditions include:

• Clear skies or partly cloudy nights
• Calm winds
• High dew point (a measure of moisture in the air)

Frost forms when warm, moist air near the ground cools below its dew point. As the air cools, water vapor condenses into tiny ice crystals that form on surfaces like plants, grass, and cars.

Impact of Frost

Frost can damage plants by freezing their tissues and causing them to wilt, discolor, or die. Tender plants, such as seedlings, young plants, and tropical plants, are particularly susceptible to frost damage. Frost can also damage outdoor equipment, such as lawn mowers, grills, and patio furniture.

Protecting Your Plants

To protect your plants from frost, you can take several steps:

1. Cover Plants: Use blankets, sheets, or frost cloth to cover plants and trap warm air around them. Secure the covering with stakes or weights to prevent it from blowing away.

2. Water Plants: Water the soil around plants thoroughly before the frost advisory. Moist soil releases heat and helps keep plants warmer.

3. Move Plants Indoors: If possible, move tender plants indoors to a warm place. This is the most effective way to protect them from frost.

4. Use Heat Sources: Place small, portable heaters near plants to generate heat and protect them from frost. Be careful not to overheat the plants.

Protecting Your Property

In addition to protecting your plants, you can also take steps to protect your outdoor property from frost:

1. Cover Outdoor Equipment: Cover grills, patio furniture, and other outdoor equipment with tarps or blankets to protect them from frost and moisture.

2. Disconnect Water Hoses: Disconnect water hoses from faucets and drain any remaining water to prevent them from freezing and bursting.

3. Clear Sidewalks and Driveways: Remove any snow or ice from sidewalks and driveways to prevent slipping and falls.

Effective Strategies

• Monitor weather forecasts and heed frost advisories.
• Protect plants by covering them or moving them indoors.
• Use blankets, sheets, or frost cloth to cover plants and trap warm air.
• Water plants thoroughly before the frost advisory to release heat and keep them warmer.
• Use small, portable heaters near plants to generate heat and protect them from frost.
• Cover outdoor equipment with tarps or blankets to protect them from frost and moisture.
• Disconnect water hoses from faucets and drain any remaining water to prevent them from freezing and bursting.
• Clear sidewalks and driveways of snow or ice to prevent slipping and falls.

FAQs

Q: What is the difference between a frost advisory and a freeze warning?
A: A frost advisory is issued when sub-freezing temperatures are expected between 33°F (0.6°C) and 36°F (2.2°C), while a freeze warning is issued when temperatures are expected to drop below 32°F (0°C).

Q: How can I protect my tropical plants from frost?
A: Tropical plants are very sensitive to frost and should be moved indoors to a warm place before the frost advisory. If this is not possible, cover the plants with blankets, sheets, or frost cloth and place them in a sheltered area.

Q: Will frost damage my lawn?
A: Frost can damage newly seeded lawns or lawns that are not well-established. However, established lawns will typically recover from frost damage in the spring.

Q: What should I do if my car is affected by frost?
A: If your car is covered in frost, use a brush to gently remove it. Never use hot water or scrape the ice off with a hard object, as this could damage the paint or windshield.

Q: Is it safe to leave my pets outside during a frost advisory?
A: Small pets, such as puppies and kittens, should be brought inside during a frost advisory. Older pets or those with health conditions may require additional protection, such as a warm coat or heated blanket.

Call to Action

Protect your plants and property from frost by taking the necessary precautions. Cover plants, move them indoors if possible, disconnect water hoses, and clear sidewalks and driveways of ice and snow. By following these tips, you can minimize the impact of frost and ensure the safety of your plants and property.
