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.

Concentrated vinegar is one of the best methods you can use if you wish to avoid chemicals. Highly concentrated horticultural vinegar will work on many broadleaf species. Household vinegar is not strong enough to do more than kill the leaves, which will over time reduce the vitality of the plant but must be applied several times to keep the leaves from forming and producing plant sugars.

Weeds with deep taproots, such as dandelions, are not as easily removed with vinegar, as the roots can reach nutrients deep down in the soil. Consistent pulling may also have an effect on some weed species but if you can’t get the entire root, many varieties will simply sprout anew.

Even normally desired plants, such as rhubarb and some berries, will slide along into the splits in the pavement, using such chinks as natural growing areas. Yarrow, pigweed, gumweed, and flowering prickly lettuce are other weed species that thrive in the gaps of pavement.

How to Treat Weeds in Cracks Naturally

The adaptability of weed species is to their advantage and the home owner’s loss. Let the games begin.

The use of herbicide is one of the best ways to kill the roots of weeds in the pavement. There are several formulas to purchase that target different types of weeds. Brush and berry plants require the strongest formula available, but be cautious, as these are not necessarily selective and any nearby plants can be affected by drifting spray.

Types of Weeds in Pavement

Weed control on pavement cracks that are slim is the most difficult of all because pulling generally leaves behind the roots.

Cracks and crevasses in the pavement are comfortable and sneaky hiding places for weed seeds. Weeds in the pavement are advantageous and use these convenient locations to secrete their seeds until growing conditions are optimal. Breezes and other movements funnel seeds into holes in the pavement where they are protected from further eviction.

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.

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.

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.

Boiling Water

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.

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.

Homemade Vinegar Herbicide

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.
