Even with warmer temperatures outside, there can still be some nights when freezing temperatures could affect potted plants and seedlings in your vegetable garden. To protect your plants at night, upcycle old bubble wrap into mini greenhouses. Since the air bubbles in the wrap help retain heat and allow sunlight in, you can insulate your plants by simply running sheets of bubble wrap on top or around the base of the plant. When you’re done with the wrap, pop the bubbles and toss the sheet into the same bin that accepts plastic shopping bags for recycling.
