How Do I Protect Plants From Frost?

 

Protecting Your Plants from Ice

As cold weather begins, plants are in danger of a freeze occurring when temperatures drop below 32° F. At these low temperatures, plant cells may rupture causing irreparable internal damage. As winter weather fluctuates, freezing and thawing can cause serious damage, especially to perennials and shrubs. Luckily, there are simple steps you can take to prevent damage to your plants.

  • Water before a Freeze: Water plants thoroughly before a freeze to prevent dehydration and add insulation to the soil and plant cells. Otherwise, it is best not to water your plants until temperatures rise above freezing.
  • Insulate the Ground: Before snow falls, spread a 2- to 4-inch layer of mulch around your plants. A layer of mulch protects the roots of these plants from sustaining damage.
  • Cover Your Plants: Protect garden plants with a row of plant cover to protect against frost and wind. Just be sure to remove any snow from the cover to prevent it from weighing down your plants.
