At Bering’s Hardware, employees are telling customers to use materials already found at their homes.
“You can use sheets, burlap, or any other sort of cloth covering will help insulate that plant,” Bering’s manager Farrell Benson said. “If you absolutely have to, use plastic as a last resort.”
Before you cover, spray plants with water. Adding mulch, or leaves around the base can help as well. If you don’t, the effects will be visible.
If you use plastic, make sure it’s not touching the plant. Also, give it room to breathe, because plastic can create a greenhouse effect.
