How to keep weeds from growing in driveway

Driveway and sidewalk cracks turn out to be surprisingly friendly places for weeds. These cracks can hold a considerable amount of soil and organic matter, a perfect bed for grass and weed seeds, which are often very tiny. And just below the surface of the paving there is often trapped moisture, and any plant that sends its roots down below the slab has access to it.

In cold weather, a dark-colored asphalt driveway absorbs sunlight and keeps the soil beneath warmer than the surrounding landscape. Some grasses and weeds can easily tolerate the salts in ice-melt products. Fescue, for instance, is a cool-season grass that is somewhat salt-tolerant and might have a good chance of surviving through the winter in a driveway. Sedge is a grass relative that tends to stay green in winter. And then there are the cold-happy weeds such as chickweed that seem to scoff at temperatures at which other plants would have long disappeared.

Grasses and weeds growing out of pavement cracks in sidewalks, driveways, and patios is a common annoyance. Sometimes it seems as though these unwanted plants grow even better in tiny pavement crevices than they do in the lawn and garden. This defies all logic since pavement surfaces are brutally hot and dry places where you might think that nothing could survive. But not only do these tenacious grasses and weeds survive, they alsoseem to positively thrive in this no man’s land of blistering hot pavement.

Before Getting Started

The reality is that pavement weed control is an ongoing landscaping maintenance task for homeowners, but the work is easier if you have a variety of workable strategies to choose from.

You can stay on top of weed control by devoting a bit of time to the job each week. Many homeowners like to conclude weekly mowing or garden work with a few minutes spent plucking or killing the weeds sprouting out the pavement cracks around the landscape.

To seal cracks and crevices in your driveway, pick up some cement filler at your local home improvement store. Most major home improvement stores sell this filler for about $7 to $10 per tube, which is a small price to pay for protecting your driveway from weeds. After the cement filler has hardened, it will form a solid barrier to protect your driveway from the intrusion of weeds.

You can make your own weed-killing herbicide by mixing white vinegar, salt and dish soap together. After combining the three ingredients, pour it into a spray bottle and apply generously to the weeds while using caution not to get any on your “good” plants.

If you have weeds growing in your driveway, you should first eliminate them. Assuming they are growing in small cracks, however, you probably won’t be able to pull them up entirely – not without breaking them in half, at least. Therefore, it’s recommended that you use an herbicide to kill them.

The only downside to using boiling water is that it may cause serious burns if you accidentally spill it on yourself. So, if you plan on using boiling water, carefully pour it over the crack to minimize the risk of injury. You may even want to wear gloves when handling a pot of boiling water for this very reason.

An alternative solution to eliminating weeds from your driveway is to pour boiling water on them. Boiling water is a natural, Eco-friendly alternative to chemical-based herbicide. The scalding-hot temperatures will instantly kill weeds upon contact. Best of all, it’s completely free and takes only a couple of minutes to make.

In addition to lawns and flowerbeds, weeds can also appear in small cracks in the driveway or sidewalk. So, what’s the best way to prevent weeds from appearing in these cracks?

After the weeds have died, you should seal the cracks in your driveway to prevent them from coming back. Even if you eliminate the weeds currently taking refuge in your driveway, there’s a good chance of them returning in the future – unless, of course, you seal the crack.

Trying to prevent weeds can seem like a never-ending battle. You may pull up one weed, only to discover two more that have taken its place. To make the problem worse, weeds can emerge just about anywhere.
