Driveway weeds, once left alone too long, can make your house look like it hasn’t been inhabited for years. They’re also notoriously hard to get rid of. Pulling them out is hard because they’re stuck in the cracks, pruning them only encourages them to grow thicker, and smashing your concrete driveway to get at them is absolutely out of the question.

Chemical weed killers are an easy option to take for many people, but in these environmentally-conscious times, it’s better to think twice. Chemical weed killers are effective, but they may be too effective and end up killing other plants in your garden without you meaning to. This article will tackle all alternatives to commercially-produced chemical weed killers. Read on to learn more.

Salt, Vinegar and Detergent

Salt, vinegar and detergent are three household items that are readily available anywhere. Combined, they can make a potent weed killer. Here’s how to make this kind of weed killer.


  • 1 cup table salt
  • 1 gallon vinegar, 5% acidity
  • 1 tablespoon liquid detergent


If a gallon of vinegar sounds too much, you can reduce the proportions to a quart of vinegar, . However, keeping extra supply of your weed killer will come in handy, as its effects, while potent, aren’t permanent.

  1. Dissolve the salt in the gallon of vinegar and stir until all the granules have disappeared.
  2. Slowly add the tablespoon of detergent. Mix well.
  3. Put the weed killer in a spray bottle and spray the offending weeds in your driveway until they are thoroughly wet.
  4. The weeds should turn brown and dry out in the next couple of days. Spray any new weeds that sprouts up in their place.
  5. Keep this away from your other plants that you don’t want to kill. This mixture is environmentally friendly, but can be damaging to other plants when applied.

Table Salt

Applying table salt to the weeds in your driveway is another environmentally-sound way of getting rid of them. Make sure that you do this method when you’re more or less sure that the next few days will be sunny. Apply table salt liberally on each weed that grows in your driveway. The salt will cause the soil the weeds grow in to be unbalanced, causing the weeds to die away. (For other uses of salt, read how to make use of household salt)

Boiled Water

If you’re not comfortable with using any sort of substance that will stick in your soil for too long, you can try boiling water instead. Be careful not to burn yourself as you pour the boiling water into the cracks of your driveway. This can kill your driveway weeds, but again, it’s not permanent. You may have to repeat this every other week.


Using a blowtorch may sound extreme and dangerous, but if you own one and know how to use it, why not? A blowtorch shows instant results, but be careful when using one. You may also end up leaving scorch marks on your driveway pavement, so use a blowtorch with care.

Fill the Gaps

Weeds are ultimately encouraged by the widening gaps in your pavement. If you can’t afford to re-pave your driveway, there is a cheaper alternative: Filling the gaps. A number of materials can be used to fill the gaps in your driveway, environmentally-friendly and poses no threat to your other, more valuable plants. Here are the materials you can use when filling the gaps:

  • Shredded bark mulch (For more information on mulches, read The Guide To Mulch)
  • Pebbles
  • Thyme

If you want to seal the cracks, you can do so by using polymeric sand. Polymeric sand is especially effective for small, hairline cracks. They can be poured and swept into the cracks, and once settled in, will form a barrier that will seal off any weeds attempting to grow through it. Polymeric sand can be bought in most household stores. If you want to be environmentally-friendly, go for the one that’s organically binded.

You can use any of these methods or better yet, combine them for a more effective way to clear your driveway of weeds. These are all environmentally-friendly, so you won’t have to rely on chemical warfare again. Good luck. For more information regarding this article, read how to control weeds in your garden.
