How Do I Stop Weeds From Growing In Concrete Cracks?

Concrete is such a versatile and affordable building block that it’s not uncommon to see it used for patios, sidewalks and flooring in many modern homes. Its durability makes it the perfect choice for any type of project that is going to be exposed to the weather. However, like all things that stay outside they are prone to the whims of nature, in this case that means weeds. All homeowners with concrete pavers at some point find themselves asking the same question: “How do I stop weeds from growing in concrete cracks?”. We have the answers. 

 

Preparation

Make sure you have the tools you need to combat weeds quickly and effectively. This is a problem that will continue to recur every year as new plants grow and bloom. By investing in the proper tools upfront you can set yourself up for long-term success. Our suggestions for proper weed maintenance tools include:

  • Pressure washer
  • Polymeric sand
  • Outdoor broom
  • White vinegar
  • Dish soap
  • Spray bottle

 

Checklist

The first step is always to kill the weeds. It’s incredibly difficult to remove live plants, and if any part of the root system remains they will grow back. We recommend either purchasing a weed killing mix, or combining water, white vinegar and dish soap in a spray bottle. Once you have sprayed the weeds, wait until the mixture has killed them. 

 

Once the weeds are dead remove all the plant matter from the concrete joints. It’s important that these cracks are completely clear before moving on to the next step. 

 

Once the weeds have been removed and the concrete cracks have been cleared it’s time to make it so no weeds can grow back in that area. The best way to do this is to fill the cracks with polymeric sand. You can then use a broom to wipe off the excess sand. 

 

Once the sand is placed, take the time to mist the sand with water to help it strengthen and seal all of the gaps in the concrete. This will prevent determined plant roots from gaining hold and growing. 

 

Consistency 

As with anything that’s exposed to the elements, consistent maintenance is imperative. The reality is plants and weeds will continue to grow, which means the weed removal process is going to have to be repeated occasionally. The good news is the better you are at following these steps, the less often you’ll have to deal with weeds.
