Tips for Handling a Cold Snap

Tips for Handling a Cold Snap

Light freeze: Nighttime temperatures drop to 32 degrees or below

Hard freeze: Temperatures fall below 28 degrees

Freeze warning: When temperatures are expected to be 29 – 32 degrees

Watch the weather! When we are under a freeze warning or when the forecast drops below 40 degrees consider covering your plants and moving them inside your garage or home.

• Move tropical plants inside your house. These plants are the most sensitive to cold temperatures!
• If possible, water thoroughly a day or two BEFORE the cold snap begins. Watering during cold weather won’t harm your plants. Water is needed to maintain good health and is even more necessary if conditions are windy.
• Moved potted annuals/vegetables and hanging baskets into your garage to spare them from the wind and cold. Move them outside again into the sun when temperatures are more favorable.
• For items that are too large or cumbersome to move, consider covering them.
  • Use fabrics such as light blankets, burlap sacks and old sheets
  • Avoid plastic. It will trap moisture and conduct cold
  • Cover plants in the early evening before the temperature drops to help hold the days warmth
  • Extend your covering to the ground to trap as much heat as possible
  • Use stakes, rocks or bricks to hold your cover in place
  • Remove covers during the day, if the temperatures are above freezing, to allow for sunlight and circulation.
  • If the cold lasts all day, consider leaving your covers on for the day
• Perennials generally don’t need much protection for light frost. Adding a layer of mulch 2-3 inches thick around the base of your perennials helps to insulate plants.
