What to Do When a Freeze Warning is Issued: Protecting Plants and Property
Every spring and fall, many communities face sudden temperature drops. When a freeze warning is announced, quick action can make all the difference for your plants and property. This article explains what a freeze warning is, why it matters, and how you can prepare to avoid damage.
Gardeners protect delicate plants during a freeze warning by covering them overnight.
What Is a Freeze Warning?
A freeze warning is issued by weather agencies when subfreezing temperatures are expected. These forecasted lows can cause harm to crops, delicate plants, and even property. In Michigan, recent forecasts have led to wide-ranging warnings. According to MLive, almost every county in Lower Michigan except for two was included in either a freeze warning or frost advisory this week. Cold snaps like these make it essential to prepare, especially if you have a garden or sensitive outdoor plants.
Impacts of a Freeze Warning
When temperatures plunge below 32°F, tender plants face severe risk. Annual flowers, seedlings, and vegetable vines such as tomatoes and peppers are especially vulnerable. Prolonged exposure can lead to a "hard freeze," which may kill unprotected plants. Areas away from the immediate shoreline are at higher risk, as bodies of water provide slight insulation. As highlighted in the frost advisory for Metro Detroit, counties like Genesee, Lapeer, Sanilac, and more frequently experience these advisories when cold spells threaten.
How to Prepare for a Freeze Warning
Protecting your garden and outdoor plants doesn’t have to be complicated. Here are proven steps you can take:
- Cover Plants: Use buckets, garbage cans, or specialized plant covers to shield delicate crops overnight. Ensure covers reach the ground to trap heat.
- Water Before Frost: Moist soil retains heat better than dry soil. Water your plants during the day before cold weather strikes.
- Move Potted Plants: Bring containers indoors or up against warm, sheltered walls.
- Check Local Updates: Stay informed with updates from trusted weather services. Multiple advisories may be in effect for your county, as in recent events described here.
The Importance of Prompt Action
Sensitive plant survival often depends on how quickly you respond to a freeze warning. Experts advise storing covers near outdoor beds so you’re never caught off guard. Start monitoring your favorite weather source as nighttime lows approach freezing, particularly between 1 a.m. and 8 a.m., the most vulnerable hours.
