KNOXVILLE (WVLT) – The National Weather Service predicts that East Tennessee’s first Frost of the year may occur overnight Saturday into Sunday morning.
Forecasters say an area of high pressure is building to the north, which will allow temperatures to plunge into to the 30s across the Southwest Virginia, the Northeast Tennessee Valley, Eastern Tennessee Mountains and extreme Southwest North Carolina.
Those conditions may kill or severely damage your outdoor plants if they are left outside unprotected. According to Stanley’s Greenhouse in South Knoxville, trees, shrubs, and some plants such as pansies can withstand a freeze, but others will need to be brought inside or covered up.
"If you still have some of your tender plants outside, you need to bring those indoors this afternoon,” said Monte Stanley from Stanley’s Greenhouse. “If you don't have time for it, you might want to cover them lightly with some sheets or towels."
You can cover your plants with anything organic including cardboard boxes, but stay away from inorganic coverings such as plastic bags.
