Or perhaps you haven't managed to stop weeds from growing in gravel without dangerous chemicals, and now there are a ton of them to pull. Thankfully, there's a way to get rid of large patches of weeds on your gravel driveway all at once with minimal effort. All you need for this is a tarp or a large piece of clear plastic and some bricks or stones to keep it in place. Plastic tarps or sheeting trap moisture and heat close to the ground, creating ideal conditions for weed seeds to germinate. Using clear plastic or tarps during the hottest part of the year means that it should only take about two to three weeks to clear your gravel driveway of weeds.
