How to Get Rid of Weeds Growing Through Cracks in the Sidewalk

When we first learned about plants in school, they seemed so simple: make sure they have enough soil, sunlight, and water, and they will grow. Then we learned that it’s a little more complicated, and many different factors determine whether a plant will grow and how well.

But, as most beginner gardeners will sooner or later learn, there may be times when you do everything right (as far as you know) and no matter what, you can’t get the plant to grow. And then, at the opposite end of that spectrum, there are weeds that somehow grow through the smallest cracks in the pavement or between the bricks and still manage to thrive.

While you have to give credit to these weeds for their hardiness, you probably don’t want them in your driveway, sidewalk, or patio either. Here are some ways to get rid of them.

Pull them out by hand (at least the light ones)

Regardless of which method you decide to use, you can start by removing at least some of the existing weeds, especially those that germinate easily. Your pavement will immediately look better, and it will allow whatever you apply next to penetrate the ground more efficiently.


No wonder white vinegar is a popular natural weed killer. Water or spray weeds with concentrated vinegar for days on end and they will eventually wither, turn brown and die.


It’s basically the same method as above, except instead of vinegar, you’re going to cover the weeds with a layer of salt. Alternatively, make a solution of three parts water to one part salt and spray it on the weeds.

corn gluten

If your weeds haven’t sprouted yet, you can prevent them by spreading corn gluten meal along cracks where they normally grow.

Baking soda

First, dampen the weeds with a garden hose. Then sprinkle them with a thick layer of baking soda . It also works as a preventive measure before weeds start to break through the pavement.

Store-bought weed control

And of course, there are always traditional weed killers if you want to go that route.
