Friday morning’s frost could damage unprotected East Tenn. plants

KNOXVILLE (WATE) – If you thought the danger of the cold was behind us, think again. A Frost Advisory has been issued for all of East Tennessee and Southeast Kentucky until 9 a.m. Friday.

Frost can cause a lot of damage this time of year to new growth on plants, or even ruin some of the crops farmers rely on each year.

There are a couple of different ways you can project your plants, but there is also a wrong way.

Do not use a plastic bag when covering your plants because that will actually do more harm than good. Plastic can hold moisture against plant tissues and cause more serious frost damage.

Instead, make sure you use more of a cloth texture because that is thicker and can shield the plant from both the frost and cold temperatures.

Meteorologists at the National Weather Service in Morristown spoke about one of the key concerns with the frost threat for Friday morning.

“The length of time that’s it’s going to be at that dangerous temperature. If it’s only an hour or two, maybe the plants can survive that, but if it’s going to be prolonged four or five hours then we will start to see some damage,” said Meteorologist Anthony Cavallucci, National Weather Service Waring Coordinator.

The main impacts from this frost advisory will be damage to unprotected sensitive vegetation. April 16 is the average last frost day for Knoxville, and this event might not be the last of the season.
