Because vinegar is harmful to all plants, it should be applied using a spray bottle ad overspray should be controlled. For longer-lasting results, mix 1 gallon of white vinegar, 2 cups of table salt, and 1 tsp of concentrated dish soap and spray on all the weeds and cracks in the patio.
Regularly sweeping and maintaining your paved patio will prevent seeds from settling between the stones as well.
Method #3: Salt
Salt is another natural product that you can use to kill weeds. Start by using a 3:1 mixture of water and salt and apply to the area very carefully. Keep in mind that saltwater will also kill other plants, so take care to apply it only to the weeds.
Once they leech into the soil, weeds will have a difficult time growing. These methods need to be re-applied often to work effectively.
How to Get Rid of Weeds on a Paver Patio
To prevent weeds from growing in your paving, you can pour baking soda all over the paved area and then sweep it into the cracks. You should re-apply every four to six weeks. This method works the fastest during spring and fall but can still work during summer.
Lay a landscape or geotextile fabric before laying new pavers. After installation, fill the gaps between the pavers with stones to further inhibit weed growth. Note, however, that landscape fabric can inhibit water drainage, so ensure that the soil is well-draining by amending it with organic matter before application. Also, regularly remove debris that accumulates between the pavers.
Getting rid of weeds can seem like a never-ending chore. They’re not just garden pests; they’re also an eyesore when they gather between the brick pavers that are usually so attractive. This is especially a problem if there are gaps between the pavers rather than those that are interlocking. To keep weeds at bay in those spaces, adopt one or more control techniques, some of which are put in place before laying the bricks.
Spray a ready-to-use, pre-emergent herbicide that is labeled for the problem weeds that were previously growing where the pavers are installed. Spray this type of herbicide in the spaces between the pavers until the ground is wet. Do this just before those weeds are expected to germinate, often in early spring or summer, depending on the type of weed and product.
Dig into the soil between the pavers and plant a groundcover that is hardy in your area and is tolerant of the sunlight conditions where the pavers are located. Plant individual plants as deep as the nursery containers, and at the closest recommended spacing for quick coverage. For example, blue star creeper (Isotoma fluviatilis) — which is hardy in U.S. Department of Agriculture plant hardiness zones 5 through 9 — makes an excellent groundcover for such purpose. In mild Mediterranean climates, you could also plant Bowles’ common periwinkle (Vinca minor “Bowles”) in USDA zones 4 to 9.
Spray weeds until they are wet with a ready-to-use nonselective herbicide product, such as one with glyphosate. Do this two weeks before laying the pavers. Respray weeds that are still alive with the herbicide in one week. Discard the dead weeds.
Once you remove the weeds through one of the methods mentioned above, stabilizing sand can be used to help keep any roots from growing back. When adding sand, it is essential that the patio is dry and free of weeds. Some paver sands feature gel additives that react with water, filling in the space between the stones so weeds have nowhere to go. Some sands also feature a pH that inhibits weed growth by making it uninhabitable. The type of sand used will help to determine the proper installation method. Follow the instructions carefully to ensure the product is used properly.
Patio pavers bring a traditional elegance to the exterior hardscapes of any business or residence. Nothing will detract from the beauty of the pavers faster than the growth of weeds. When no weeds are present, simple preventative methods will help to keep them from growing. If weeds are already a problem, there are a number of methods that will eliminate the weeds. Discovering the best weed prevention and remedy for your paver area is easy when you understand what causes weeds in the first place and the pros and cons of each weed control method. A weed-free paver area is possible and goes a long way toward making a space inviting and enhancing the curb appeal of your home.
Pressure washing the whole patio is a dual-purpose solution. Not only will it remove the weeds from the spaces between the pavers, but it will also provide a deep cleaning to the pavers, making the whole area look like new again. If you are pressure washing, do not simply use a jet nozzle. The water pressure from the nozzle can wash away the sand between the grooves and etch the surface of the pavers themselves. Instead, use a rotating surface cleaner attachment in tandem with the pressure washer.
Most of the time, weeds to not sprout up from beneath the pavers. They actually start with seeds that settle between the cracks of the pavers on the surface. Seeds need to take root in order to grow. Sweeping your pavers regularly will disrupt the seeds prior to rooting, helping to inhibit weed growth. Sweeping also removes surface dirt and helps to enhance curb appeal by keeping your pavers looking clean.
Instead of treating weeds with harsh chemicals, open the pantry and reach for the white vinegar. Pour the vinegar into an empty spray bottle and spray the cracks between the pavers, leaving it to sit and work its way into the sand. When a few hours have passed, rinse away the vinegar with a garden hose. This simple remedy will kill the weeds without damaging the pavers or damaging nearby plants. Vinegar should not discolor pavers but if you have any concerns, do the same process with an inconspicuous test spot before treating the entire area.
Pulling weeds is a classic method of removal but it is only effective if the entire plant is removed, root and all. To do this, reach for the lowest point of the stem and carefully pull the weed. Any roots that don’t come with the plant will grow back. This often results in multiple hand-pulling sessions before the problem is remedied. Hands-on removal is possible at the onset of a weed problem, when only a few weeds are present, but it can become a very labor-intensive and less effective method when there is a severe weed problem.

Weeds thrive in cool, damp soil. When the deck or patio is properly sloped, water runs down the slope and doesn’t stay stagnant in the crevices between the pavers, helping to prevent the conditions weeds need to thrive. The slope of the paved area should always tilt away from the house.
When weeds are already present you have to go from prevention to finding effective remedies for the problem. There are a number of ways you can remove existing weeds from your paver area. A single weed-removal method may not be enough. It may be more effective to combine two or more of these strategies, depending on how severe the weed problem is. Once the problem has been rectified, go back to the prevention methods to keep them away.
