weeds growing through pavers

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.

Whether you’re putting down new paving or refreshing old paving, there’s a ton of ways to deal with weeds growing between them. Once you’ve already got a weed problem, it can be difficult to take care of, but there are several ways to resolve the problem in the beginning.

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.

While the best way to get rid of weeds is to prevent them from growing in the first place, there are several ways to remove those that have already started to grow on your pavers.

Once the larger weeds are removed, pressure wash around the stones.

Preventing Weeds From Growing on a Paver Patio.

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.

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.

The goal is to remove debris and sand from the joints while not disturbing the bedding layer that the pavers are resting on. You’ll need to continue to do this regularly to keep the weeds at bay.

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.

Post-emergent herbicides work on actively growing weeds and are divided into two categories: selective and non-selective.

Once they leech into the soil, weeds will have a difficult time growing. These methods need to be re-applied often to work effectively.

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.

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.

There are several ways to prevent weeds from growing on your patio again. Baking soda, vinegar, and herbicides can all be used to prevent them from growing back.

Weeds can grow in even the smallest cracks in a patio if you don’t take precautions to prevent them. When you properly install pavers, weeds have a difficult time growing up through the spaces between them.

Method #1: Baking Soda.

When installing or refreshing pavers, weed growth is something to think about. Getting rid of weeds on your patio can seem like a pain because they are experts at finding places to grow.

Let’s look at a couple of ways to prevent and get rid of weeds on a patio.

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.

Like the baking soda and vinegar methods, this is effective since salt dries out the plants to the roots and has a lasting effect.

To get rid of weeds with baking soda, moisten them with your garden hose and then sprinkle the soda on top of the entire weed.

But don’t worry, you’re not defenseless against weeds and other invasive plants.

You can use chemical herbicides to treat weeds on pavers as well, and there are two general types: pre-emergent and post-emergent. Pre-emergent herbicides work on plant seeds and seedlings, and they form a barrier to prevent germination.

Method #3: Salt.

For a low-cost solution, you can pull the weeds by hand and then pressure wash the pavers to get rid of roots. For this method to be effective, you should always pull the largest weeds by hand because they’re difficult to remove with a pressure washer.

The high concentration of salt in this formula prevents them from growing back.

Regularly sweeping and maintaining your paved patio will prevent seeds from settling between the stones as well.

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.

Baking soda, or sodium bicarbonate, works by overloading the weed with salt, causing it to dry out all the way to the roots and die.

You can prevent them from even getting a foothold in your patio by using polymeric sand, natural products, or a chemical solution. Be proactive and make your patio weed-free from day one!

So I turned the tables and rather than recommend methods of getting rid of weeds between pavers without trying them, I rejected certain methods without trying them. You’ll see my logic in a minute.

Prevention.

Results were very satisfactory (check out my photos!). The weeds immediately lost their oomph. An hour after treatment, they were seriously droopy. And by the next day, they’d become so dry and shriveled I could just sweep them away with a broom.

My method of choice was … wait for it …. boiling water!

Treating an extra-large paver-ed area with a kettle of freshly boiled water might not be practical. Instead, try pressure washing. Hot water works best. To avoid harming your pavers, follow manufacturer’s directions and start with a low pressure.

As a home and garden writer, I’m amazed at the plethora of online tips and tricks to solve problems from eliminating weeds between pavers to using up a bumper crop of cucumbers. While some come from reliable sources, I’m pretty sure many recommendations – whether dangerous, ineffective, or wildly expensive in proportion to the problem they promise to solve — have never actually been tested by the folks who promote them.

Impatient though I was, I took time to research weed removal methods and choose the best. Read how I got rid of all the weeds between my pavers, the easy, green way.

FINAL SCORE: Laura 1, Weeds 0.

What I actually used – with great results.

Advantages: Boiling water is cheap and readily accessible. What’s more, it has no long-lasting negative effects on the environment. The liquid hits those weeds with sizzling force, but by the time it drains off and reaches the lawn and garden, it’s cooled down harmlessly.

Treat extra-large areas.

Methods I rejected.

If you hire a contractor to build a new patio, make sure that there’s adequate drainage and pavers are fitted tightly together.

What’s growing between your pavers: weeds, moss, even tiny trees? If you answer “all of the above,” you’re in the same boat as I was until recently. Seemed like my patio was more vegetation than bricks and I wanted to fix it … fast.

Salt . Applying salt to weeds between pavers sounds green and simple. However, heavy rainfalls have a way of spreading this substance from paved areas to the surrounding soil. And Gardening 101 says salt kills all vegetation, not just the kind you don’t want.

For both new and existing paver installations, fill the joints with polymeric sand. This blend of sand and special additives resists weeds, insects, and erosion.

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.

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.

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.

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.

White Vinegar.

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.

Installing pavers results in spaces between the bricks or stones. The first step in preventing weeds is ensuring proper installation. A sand bed tightly packed provides a level foundation for the deck or patio. Once all the pavers are in place, additional sands should be packed into the crevices. This sand ensures each paver stays in place and helps prevent weed growth.

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.

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.

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.

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.

Prevention is one of the best methods of weed control. With a little regular maintenance, weeds can be avoided in the first place.
