BROADWAY, Va. (WHSV) - Arlene Reid with Glenhaven Greenhouse in Broadway said cold spells in the early spring are quite common in the Valley. Understanding how certain weather impacts the plant is vital to their health.

“A freeze is different from a frost,” Reid said. “You can wash frost off. You can’t wash a freeze off.”

She said it takes about two days of freezing weather to damage the plants, but the best way to protect your plants is to bring them inside, but if you can’t do that, covering them is the next best thing.

“Towels, and blankets, things that are going to breathe really well... even a thin garden fabric- we use at the greenhouse- we do double it to make it a little thicker, but it doesn’t crush your plant as much. Never plastic. Never plastic,” Reid stressed. She added thin sheets or paper won’t help. When covering, the material should be tucked in a way that the wind won’t remove it.

Reid said May 10 through the 15 is known as a ‘safe date’ to plant, but it all depends on where you are and the temperature for that particular area.

She said if you already have plants, re-pot them and have them mobile where they can easily be moved during cold snaps.
