How to stop weeds from growing in driveway cracks

Dig out as much of the weed as possible before cleaning out any remaining dirt or debris from the crack with water and a stiff wire brush. Allow the concrete to dry before continuing.

Pack the crack tightly with sand before filling it with a quick-drying joint sealant. Cut the sealant’s tip and insert it directly into the crack. Squeeze the product into the crack and overfill to allow for the shrinkage that occurs after drying.

Spray the weeds with a 5-percent acetic household vinegar. Concentrate the spray on the weeds, reapplying several times over a two- to three-day period or until the weed tops and roots are dead.

Aside from being aesthetically unpleasant, weeds poking through sidewalks pose several threats to your asphalt, and family. If left unattended, the weeds will thrive, grow and can eventually create severe concrete deformations and heaving, which is only mended by tearing out the slab. Larger weeds are also tripping hazards, and will continue to reemerge after countless applications of herbicides. Manually eradicate the weeds before prepping the cracks and applying a quick-drying joint sealant.

Allow the crack sealer to dry for 12 to 24 hours, or according to the package directions. Examine the crack and reapply, if necessary, to fill any remaining small holes or voids in the hardened product.

If you have a serious weed problem in your driveway or patio, glyphosate can be an effective solution. Soil enzymes neutralize it, so it’s unlikely to hurt plants that you don’t spray it on. However, it’s still best to apply it carefully so you don’t drip or accidentally spray plants you want to keep.

Do you have some weeds that seem to come back no matter what? You might need to fight them with fire. A small propane torch can be effective at spot-removing weeds in stone patios, driveways, or sidewalks.

Use Glyphosate

If you have just a few weeds popping up, standard hand-weeding can be effective. Grab some gardening gloves so you don’t scrape your fingers on the stone. Pull up the weeds carefully, getting as much of the root as possible. This will help prevent the weeds from growing back.

Whether you’re willing to work with your hands or you want weed remover to do the work for you, there are plenty of solutions. Using the right tools and weed removers helps you get rid of weeds permanently. Once you have the situation under control, you’ll be able to keep weeds away without much work at all.

Let’s start with why grass and weeds are attracted to sidewalk cracks. The cracks and crevices look small, but the spaces between pavers hold an amazing amount of dirt and organic matter. This matter gets swept by wind and rain and snow. Those crevices also hold onto moisture a little longer than flat surfaces, so it’s a perfect incubator for the weed seeds or grass.

Before you reach for the spray bottle of Roundup or some other toxic weed killer containing glyphosate, take a look in your kitchen. You may already have all the ingredients to kill weeds and grass in driveway cracks. Homemade solutions are both cheap and eco-friendly.

The setup also gives grass and weeds a little protection from you. It’s tough to get to the grass roots, or taproots of the weeds when all you can do is try to pull the unwanted plants by their tops. And you’re not likely to mulch those areas, as you would your flower beds, to prevent a return. But you can find everything you need to get to the root of the problem, in your kitchen — without turning to chemical herbicides sold at the garden center.

The good news is that because the unwanted intruders are in driveway or sidewalk cracks, you don’t need to be as precise when applying your homemade remedies. A poorly aimed squirt has less of a chance to hit and accidentally kill desirable plants.

First, a word of warning: These common kitchen ingredients aren’t toxic in small doses, but they’re not benign, either. “Several can be harmful to people/pets during mixing and application, owing to inhalation, skin or eye contact, or spray mist. Some have unpleasant smells or have an allergenic effect,” writes Deborah Smith-Fiola and Stanton Gill for the University of Maryland Extension. Some hazards are obvious: Boiling water can burn you if you are not careful with it. Others aren’t as obvious. Don’t take chances and handle all of them carefully.

Details and cautions

Maybe you got a nasty notice from the homeowners association. Or maybe you spent the weekend weeding, only to come home and find grass or dandelions poking up between your pavers or the cracks of your sidewalk. They’re unsightly and can cause serious damage to your walkway.
