Greenhouse Effect

My seedlings grow better early in the growing season because I cut the bottoms off 2-liter plastic bottles and use the tops to protect the tender sprouts. On warm days, just remove the cap to ventilate. —Shirley Salyers, Columbus, Ohio

Use plastic bottles to help fight weeds in your garden. Cut off the tops and bottoms, put the bottles around plants you want to protect, and then spray weeds with a total vegetation killer.
