If weeds occasionally pop up, a spray weed killer can be used. Using an herbicide like RoundUp will not harm the pavers, and offers a quick solution to unsightly weeds on your patio or driveway.
ROUNDUP® is ideal for use on paving, paths and driveways, as it penetrates right to the weeds to ensure a complete kill.
If there is no discoloration than you'll be fine to spray the weeds and grass in your brick patio.
You can use salt, baking soda, vinegar, or chemical herbicides to kill weeds and prevent them from growing again. It is not too late to revive your beautiful pavers.
The best way to get rid of unwanted weeds from patio seams, cracks, and other hardscape areas (like walkways) is to use a liquid weed control like Ortho® GroundClear® Super Weed & Grass Killer. Not only does it kill 175 types of weeds and grasses, quickly, but it works deeply, too.
Specially designed narrow-bladed weeding tools – sometimes called 'dandelion weeders' – for tackling such weeds are the most effective. More generally, a 'block paving knife' can be run along between pavers to sever most weeds. A wire-bristled 'block paving brush' is good at removing moss and the smaller weeds.
Kill weeds between pavers with vinegar.
Spraying vinegar on the leaves and stems of weeds will kill them, so this is a viable option. However, vinegar in an indiscriminate killer, so it will also kill any wanted plants with which it comes in contact.
Removing Brick Pathway Weeds Without Herbicides
The answer is hand picking or steaming. Yup. Steaming is the easiest and longest lasting. If you have weeds growing in your brick patio or driveway, a home steam cleaning machine offers an easy way to kill them at the roots without harmful chemicals.
Similar to cleaning pavers with muriatic acid, avoid an intense concentration of bleach, as it can damage the pavers.
Yes, rain affects herbicide efficacy because rainwater simply washes it away from the surfaces that need treatment. This is why it is not advised to spray weeds when it's raining or right before it's about to rain. Herbicides need to be absorbed into the leaves to kill the unwanted plants.
Is Bleach a Better Weed Killer Than Roundup? While bleach has some weed-killing properties, it falls short when compared to Roundup, a widely used herbicide. Roundup, also known by its active ingredient glyphosate, is designed specifically for effective weed control.
ROUNDUP® Fast Action Path Ready To Use Weedkiller is designed to be used all over the garden, including paths, patios and drives. While some weedkillers may stain or discolour, this formula will protect your stonework while taking care of weeds.
Sealing is indeed an effective method for reducing and prohibiting weed growth, but it is not a foolproof solution. Paver cleaning and sealing provide a clean slate and help stabilize the joint sand, making it harder for weeds to infiltrate.
Is Roundup Safe to Use? According to the EPA, there are “no risks of concern to human health from current uses of glyphosate” if products are used as directed.
A professional jet washing service can effortlessly remove moss and mildew from your patio, walkways and paths, as well as banish those stubborn weeds.
Another idea is to spray a solution of vinegar, salt and dish soap between the bricks. The vinegar and soap kills the grass, whereas the soap makes it stick. You can even add some food coloring to help you remember that it's a homemade herbicide and not just water.
FYI although Roundup works well for killing weeds, it won't be able to remove moss in your pavers.

Baking soda is the key ingredient to killing unwanted weeds from any cracks in your your sidewalk or driveway. It's the same ingredient you use when baking cookies, so you don't have to run out of your house and buy something new. Baking soda is sodium bicarbonate, which is phytotoxic to plants.
Whilst vinegar will not directly dissolve concrete itself, but it will degrade the cement that binds your concrete slabs or flags together. Extended exposure to vinegar will also cause any polish or sealant on your pavers to erode over time, leading to bleaching, stains and weathering.
Baking soda is an amazing household cleaner, and it can work really well on your pavers too.
The risks are much greater once it dries, and since it has a half-life of up to 197 days, the dangers of the dried chemicals becoming airborne, particularly on sports fields and in high-traffic areas, are significant.
