How to Kill Weeds in a Gravel Driveway

What’s the least toxic way to get rid of weeds in my gravel driveway? I’d rather not use harsh chemicals, but there are too many to pull them up by hand. -BJ

Because you’re weeding a gravel area, you have the advantage of not having to worry about killing desirable grasses or garden plants, and less of the product will come into contact with garden soil. Nevertheless, everything we do in the garden has some impact on the environment, so you’re wise to minimize the use of chemicals. Here are some ideas:

  • Barriers: The next time you replenish the gravel in your driveway, consider putting down landscape fabric or plastic first, to prevent weeds from sprouting through the gravel. You can also put barriers around the edges, to help keep weeds and grasses from creeping out of your lawn.
  • Heat: To kill weeds using heat, carefully pour boiling water directly on the plant. Or, you could try using a paint stripping heat gun to crisp the weeds in your gravel.
  • Vinegar or Soap: Vinegar and herbicidal soaps kill (by drying out) all vegetation in their paths, but they are thought to kill beneficial microbes and sterilize soil. This is less of an issue in your gravel drive, although you should consider that some of the product will run off into drainage areas.
  • Herbicides: If you resort to organic or chemical herbicides to control weeds in your drive, you can minimize the environmental impact by carefully painting the liquid directly on the leaves, or by using a shield to target the weeds.

    if you hook up a long hose or a series of hoses attached to your hot water outlet for your washing machine, you can give your driveway a hot water bath ,killing the weeds (careful of run off on lawn, grass more fragile than weeds) I’m a landscaper.

    Hi, Irma,
    Rock salt should work — just take care to pour it on grass that you never want to return. It’s powerful stuff! Also, monitor the animals, because no living thing can consume too much salt without becoming dehydrated. That’s unlikely to happen, but it’s better to be safe than sorry.

    Good luck!

    Hi, Tom,
    Absolutely — if there are no nearby plants or grass that you want unharmed.
    Try it and tell us how it works out.
    Good luck!

    I have a very long gravel driveway. How do I kill weeds growing in the gravel using house hold products? I’m not concerned with killing grass but would like to find a way to control weed growing. Everything I try, such a round-up, works for a short while but it’s expensive and the weeds come back worse than when I started. HELP!!!

    I have a very long drive that circles the house, garage & garden. I need to find a safe way to kill weeds and make one time a year do it! What is the most effective. I thought about salt but wondered about the run off killing my grass.
