You can also use polymeric sand to fill the joints between pavers to lock the joint together and prevent weed growth. Polymeric sand is not ordinary sand, it is a super-fine sand with additives like silica that form a binding agent when mixed with water to better seal cracks between pavers.
Regularly sweeping and maintaining your paved patio will prevent seeds from settling between the stones as well.
While it’s hard to get rid of weeds on a patio once they’ve started to grow, you can set yourself up for success when you first install your pavers.
Vinegar, like baking soda, is a natural household product that is safe to use as a weed killer. Vinegar has acetic acid, which draws the moisture out of plants causing them to die. Vinegar is extremely fast-acting and will result in brown, withered weeds within 24 hours.
Preventing Weeds From Growing on a Paver Patio
Polymeric sand also improves the durability of your patio, locking pavers together so that weeds can’t find a place to grow. Because it’s bonded to itself and the pavers, polymeric sand resists erosion, protecting not only the pavers but also the base materials.
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.
Selective herbicides can be applied to your whole patio because they target just weeds while having little to no effect on the surrounding grass. Non-selective herbicides will kill every type of plant that they touch, so you should only use them in the middle of your paved area.
How to Get Rid of Weeds on a Paver Patio
Like the baking soda and vinegar methods, this is effective since salt dries out the plants to the roots and has a lasting effect.
Simple household baking soda may be all you need for your weed problems, especially if you want to kill weeds growing near decorative plants you’d like to keep. Baking soda is a natural product that will not contaminate your property or landscaping and is safe for the environment.
Finally, either with a hose or bucket, wash your patio down with water.
And store-bought weed killers have a high chemical content, with many opting for more natural methods.
This method can be repeated every four to six weeks.
When using white vinegar as a weedkiller, make sure you avoid spraying the mixture on any plants you wish to keep, as it can kill those too.
If you want to avoid using the hose, you can sprinkle baking soda after a day of heavy rain.
This depends on the hardiness of the weed, however, as you may not see results for 24 hours.
Another method for quickly removing weeds between paving stones is to use baking soda.

First, put the salt and vinegar in a jug and stir until the salt has dissolved.

An alternative to hand-pulling weeds is taking advantage of a mechanical removal solution. Crack scrapers are outfitted with L-shaped blades that pull a weed from the stem, removing the weed at the base of the stem. Normally, this method leaves behind the root, allowing for regrowth. As a result, mechanical removal is a way to temporarily restore the look of the deck or patio, but future mechanical removal sessions will be needed to remove regrowth.
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.
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.
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.
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.
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.
Is It Too Late?
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.
A deck or patio crafted of pavers is sure to have lines between each stone. Without proper prevention, weeds can find their way through those joints, reducing the appearance and potentially causing damage to the entire floor. With a few preventative measures, weeds can be avoided in the first place. If weeds are already present, there’s no need to stress. Corrective measures can eliminate the weeds and restore the look of your driveway, deck, or patio.
