Those persistent green invaders can quickly detract from the neatness of your driveway or walkway. While seemingly resilient, several effective methods exist to eliminate unwanted vegetation sprouting from the cracks in your pavement. This time-honored method is still one of the best ways to kill weeds sidewalk and restore order to your outdoor spaces. Here are seven straightforward techniques to tackle those pesky weeds fast.
Kill Weeds Sidewalk: 7 Effective Methods
Pulling Weeds by Hand
One of the most reliable ways to kill weeds sidewalk is through manual removal. This kill weeds sidewalk technique involves physically extracting the entire plant, including the root system. By carefully pulling the weeds in a way that extracts the entire plant, root and all, you will prevent the weed from resprouting. The easiest time to undertake this task is after rainfall or after you’ve watered your garden, as moist soil makes the process significantly less strenuous. Make Sure the Soil Is Moist before you begin. You can often use a thin screwdriver or weeding tool to loosen the soil around the base of the weed, making it easier to grip and pull. Extract the Plant Carefully and slowly pull the weed with a gentle wiggling motion. The goal is to extract the entire plant, root, and all, if possible, as this prevents the weed from reemerging. Once removed, vacuum out any remaining soil from the crack and fill it with mortar or masonry caulk to prevent new weeds from taking hold.
Using Boiling Water
Household water heated for cooking can serve as an effective, natural weed killer. While many plants thrive in warm conditions, they cannot withstand the intense heat of boiling water. However, it’s crucial to avoid using water that contains cooking oils or food remnants. Carry Boiling Water to the Weeds with oven mitts and carefully pour the steaming hot water over the weeds growing in your pavement cracks. Scald the Weeds from a low height, carefully pouring the steaming hot water over the weed. Pour slowly and allow the water to completely saturate the weed, right down to the roots. For particularly stubborn weeds with deep taproots, you may need to repeat this process a couple of times. After a few treatments, most weeds will surrender. Once the weeds have died, pluck them out and vacuum the area clean before filling the crack with masonry caulk.
Employing Vinegar Solutions
A common and readily available solution for tackling pavement weeds is a mixture of salt and white vinegar. The acetic acid in vinegar effectively kills most weeds and grasses. Mix the Solution in a large plastic jug: combine 1 cup of salt with 1 gallon of white vinegar (5 percent acetic acid), and add 1 cup of lemon juice and 2 tablespoons of dish soap. If you have access to horticultural vinegar, which contains 20 percent acetic acid, it can be even more effective. Be sure to wear protective gear, including gloves and a face mask, when working with any vinegar solution, as it can cause skin and eye irritation. Apply the Weedkiller by filling a small pump spray bottle with the vinegar solution and carefully spraying the pavement weeds, ensuring complete saturation of the foliage. Allow several days for the weeds to die before removing them and filling the crack with caulk.
Utilizing a Propane Torch
An ordinary propane torch can be a swift and efficient method for eliminating weeds sprouting through pavement cracks. Many weeds can tolerate a certain amount of heat, but the 2,000 degrees Fahrenheit produced by a propane flame is usually fatal. Modern tools are available with long handles specifically designed for this purpose, enhancing safety. Prepare the Torch by securely mounting the fuel tank on the torch handle. Open the valve slightly and use a spark lighter or match to ignite the torch. Once the flame is lit, open the valve fully. Incinerate the Weed by moving the live flame back and forth over the weed until it turns black and becomes charred. Exercise caution to avoid scorching the concrete or melting the asphalt. After the weed is completely incinerated, allow the area to cool thoroughly, extinguishing any remaining embers with water if necessary. Once cooled, vacuum out the ash and fill the crack with masonry caulk.
Using Non-Selective Weed Killer Chemicals
Glyphosate-based herbicides are a powerful option for killing pavement weeds. These chemicals effectively target not only the above-ground parts of the plant but also the entire root system. While effective, it’s important to follow label instructions precisely and wear appropriate protective gear, including gloves and eye protection. Mix Weed Killer according to the product’s instructions, typically involving mixing the herbicide with water. Apply the Weed Killer using a garden sprayer, carefully saturating the exposed foliage of the weeds. Glyphosate does not linger in the environment for extended periods, unlike some other weed killers. After a few days, the dead weeds can be plucked from the pavement, and the crack can be filled with caulk.
The Power of Salt and Water
A simple yet effective method involves a concentrated salt and water solution. Dissolve a generous amount of salt in water and pour it directly into the cracks where weeds are growing. The high salt concentration dehydrates the weeds, effectively killing them. This method is particularly useful for smaller weeds and cracks. However, be mindful that excessive salt use can potentially harm surrounding plants, so apply it carefully and avoid overspray.

Using Horticultural Oil
Horticultural oil is a natural fungicide and insecticide that can also be effective against weeds. It works by smothering the plant’s leaves and disrupting its ability to photosynthesize. Mix horticultural oil with water according to the product instructions and apply it directly to the weeds in the pavement cracks. This method is generally considered safer for the environment than chemical herbicides. For enhanced results, consider combining horticultural oil with a small amount of dish soap to help the oil spread and adhere to the weed foliage.
Wait and Repeat
For particularly tenacious weeds with extensive root systems, a single treatment may not be sufficient. In such cases, persistence is key. Wait a few days after your initial treatment and inspect the weeds. If they haven’t completely died, repeat the chosen method. After two or three treatments, even the most stubborn weeds will typically succumb. Once the weeds are dead, remove them from the pavement and fill the cracks with caulk to prevent regrowth.
Clean and Fill the Crack
Regardless of the method you choose to kill weeds sidewalk, the final step is crucial for long-term prevention. After the weeds have been removed, thoroughly clean the pavement cracks of any remaining soil or debris. Once clean, fill the cracks with masonry or asphalt caulk. This creates a seal that prevents new weeds from taking root and helps maintain the aesthetic appeal of your driveway or walkway. If you have it, pickling vinegar is more acidic than regular white vinegar. An even better weedkiller can be made with horticultural vinegar, which is 20 percent acetic acid. Remember to always prioritize safety by wearing appropriate protective gear when handling any weed control solutions.
