Laying a new gravel driveway for the home is already a large job, but controlling grass that pops up through the gravel afterward can feel like a constant battle. When grass is not removed properly before a gravel driveway is laid down, the grass will continue to grow underneath. It is possible to buy a variety of expensive, harmful chemicals to kill the grass, but regular vinegar or bleach diluted in water will do the job in a pinch.
Pour full strength, concentrated white vinegar onto the driveway in areas where grass has started sprouting through, recommends the Vinegar Institute. Acetic acid, a main component of vinegar, will kill grass in days. Small Farm Permaculture and Sustainable Living recommends using a vinegar that is concentrated to 10 or 20 percent.
Mix 4 ounces lemon juice and one liter of cider vinegar together inside a spray bottle if full strength white vinegar is not available. Spray the grass you desire to kill directly, being careful not to spray any plants you wish to survive in the area. Spray during the heat of the day, recommends Gardening Know How.
Combine bleach with water so that there is about 4 percent bleach in the bottle. Spray this directly onto the plant. Wear work gloves and safety goggles during application to prevent injury, as bleach can burn the skin and eyes. Bleach changes the pH of the plant, says Small Farm Permaculture and Sustainable Living, leaving salt in the body of the plant and choking it.
