How to stop weeds growing between paving stones

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.

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.

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.

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?

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

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.

Ultimately, you need to remove all of the broken cement and weeds before re-pointing between the paving slabs. Not everyone knows this, but if you have natural paving such as Indian sandstone, then it’s best that you give your patio a jet wash every couple of years as well as sealing the area. Failure in this will result in black spots, also known as lichen which can be extremely hard to remove and may require chemicals. Don’t assume that having a patio means no maintenance as this simply isn’t the case. You can find out more about black spots on your patio by clicking here. Lets look at the steps needed to stop these weeds from growing in between your paving slabs!

With any patio, you will usually have a gap between each flag stone which is filled with cement when laid. Over time, this cement weakens causing gaps in between the paving slabs and allowing for seeds to fall and grow which is when the problems begin! The longer you leave the slabs, the more the pointing (also known as jointing) or cement will crack and break which means more weeds! Some weeds can really be stuck too, where simply pulling them out only breaks the leaves and leaving the root still in tact.

Once you have jet washed the area, you will notice that a lot of kiln dried sand has also blown out. This is normal, but you do need to sweep in new sand to prevent new weeds from growing as well as prevent each block paver from moving. It’s best to purchase a weed free kiln dried sand which is slightly more expensive that the standard kiln dried sand but will last longer. All you need to do is throw it down on your driveway and sweep in using nothing but a broom! Nice and easy!

This is a common problem, since over time every driveway will get weeds eventually! The problem is that unlike patios that are typically laid on sand and cement, block pavers are actually laid on nothing but sand. And where patios have cement in between each paving stone, block pavers have nothing but sand again, or kiln dried sand to be precise. It is actually a fair bit easier to remove the weeds and prevent them from growing again on driveways where block paving has been used since all you need to do is jet wash the area which will remove the weeds quite easily, but please find a jet wash with a dirt blaster attachment. Most Karchers come with this attachment.

If weed killers didn’t work, then no company would be able to sell them, right? But that doesn’t mean that this is a permanent solution…in fact I have never agreed with weed killers because it’s not an instant fix, meaning that it takes time for the weeds to die off, and they always come back! Even when it comes to using weed killers on your flower beds, it’s best to remove them by hand and regularly turn the soil over instead of constantly paying out for weed killers which also means risking the health of your loved plants and lawn. So although in theory weed killers will kill the weeds on your patio, it won’t stop new weeds from growing between your paving stones. This is the case whether that be a patio, block paving, driveway, flower beds or anywhere else for that matter.

I went to price up a job today where the man explained that he wanted his old patio removed with new paving slabs laid due to the weeds growing in between the paving slabs themselves. I couldn’t believe that he wasn’t aware of any cheap fix which would stop this from happening in the future and after a conversation, he has now gone ahead with a jet wash and re-pointing. But it begs the question…How exactly do you stop weeds from growing in between your paving slabs? What if you have block paving? Can you ultimately stop the weeds from growing here too? Lets look at which options actually work, as well which options are permanent solutions or temporary solutions!

Removing weeds from in between your paving slabs isn’t a bad idea. It gives the immediate transformation that you are looking for compared to using weed killer, as well as not carrying the risk of damage to other plants and other adverse effects on the environment. But is there a downside? Absolutely! If weeds grew in between your paving stones before then they will grow again, and the last thing you want to do is be on your hands and knees on a monthly basis removing the weeds from your patio.
