PHOENIX (FOX 10) - Tuesday night was the coldest night the Valley saw in nearly three years.
Those frigid temperatures brought a cold snap over the Valley that Brian Blake of Whitfill Nurseries says could potentially put your unprotected plants in danger.
"Most plants damage at a frost like we're having now... 27, 28, 30 degrees," he said. "It's just going to be some leaf burn. They're going to recover."
Your plants will recover if they're covered. Blake says the key to saving your plants from a cold snap is to protect them.
No matter the type of greenery, all plants are vulnerable.
"You want to start by covering it, it's the easiest to do," he said. A frost cloth works best. If you don't have any and you're home and you need it in a hurry, just use a sheet, a blanket, any kind of fabric like that will work. Having plants wet helps, but having water running on your plants as it's freezing... it gives off more heat. That's even better and for extreme cold, you want to put like a light or a heat source underneath your frost cloth and keep it warm."
