🥶 Be ready for unexpected freezes 🥶
“Different Types of Freezes
Frosts, freeze warnings, and hard freezes (not including chill hours) all characterize different temperatures in the landscape.
Frosts – Temperatures drop below 36 degrees Fahrenheit.
Freeze Warning – 80% chance of dropping below 32 degrees Fahrenheit.
Hard Freeze – When temperatures drop below 28 degrees Fahrenheit.
When we discuss freezes impacting our landscapes, we describe two types of freezes: radiational and advective.
Radiational Freezes – Frost occurs on plants as heat escapes the plants’ surfaces (radiant heat) and they are cooler than the atmosphere. Ice will form if there is moisture in the air. Plant damage from radiational freeze may be minimized by reducing heat loss from plants.
Advective Freezes – Freezes resulting from cold, arctic air masses that cause sudden drops in temperatures.
Preparing for a Freeze
When we view our local weather forecast, we sometimes see a frost/freeze. Preparing our landscapes for frosts and freezes can help in protecting our landscapes from potential freeze damage.
To best prepare our landscapes is by following the Florida-Friendly Landscaping Program’s first principle, “Right Plant, Right Place.” Depending on where you live in [Alachua] County, we are within USDA Hardiness Zone 8b or 9a. The hardiness zones are based on the average low temperature for your area. 8b range is 15 – 20 degrees Fahrenheit and 9a is 20 – 25 degrees Fahrenheit. Selecting plants suitable for our USDA Hardiness zone will ensure your plants will experience little to no damage to our landscape plant material.
Although, some things like citrus, veggies gardens, container plants, or other specialty plants benefit from freeze protection.
