What is considered first frost?
Frost occurs when there is a solid deposition of water vapor from the air. Frost will form when solid surfaces are cooled below the dew point. An air temperature range of 33°- 36°, along with very light winds, is usually needed to initiate frost formation. At least minor damage is possible to plants.
What is a killing frost?
In gardening terms, a "light freeze" or "light frost" refers to temperatures that fall just a few degrees below freezing for a few hours. ... A "hard frost" or "killing frost" comes when the temperature drops further, below 28 degrees, for a longer time. It will kill the top growth of most perennials and root crops.
What temperature is a frost?
Now frost is a covering of ice crystals on the surface produced by the depositing of water vapor to a surface cooler than 0° C (32° F). The deposition occurs when the temperature of the surface falls below the frost point. Similarly, dew forms when the air or surface temperature falls below the dew point temperature.
What can I plant now in Zone 7?
Zone 7. In zone 7, cool-weather vegetables can usually be planted outdoors in early February. These crops include beets, broccoli, cabbage, carrots, lettuce, onions, peas, potatoes, radishes, spinach, turnips, kale and collards. Plant corn in March.
How do you tell if there will be frost?

What does Frost Day mean?

Older plants suffer more damage from cold weather and are often killed when temperatures dip below 32 degrees. This problem is rare in spring plantings, but more common in the fall.
What plants can handle frost?

A severe freeze (24 degrees F and below), sometimes called a killing freeze, causes heavy damage to most plants.
What temperature is too cold for plants?
The general rule of thumb is that most plants freeze when temperatures remain at 28°F for five hours. Of course, there are exceptions to this rule. Seedlings, with their tender new leaves, often give up the ghost when temperatures dip to 32-33°F. Tropical plants have differing low-temperature thresholds.
Can it frost at 37 degrees?
During the morning hours, frost can begin to form with temperatures as warm as 37 degrees. If it's 37 degrees at 5-10 feet above ground, it is almost always colder down at ground-level. That can cause frost to form car windows, grass, and slightly-elevated surfaces that have dipped to the 32-degree mark.
