It seems like a problem that never goes away. Whether laying fresh paving or looking to refresh existing paving, there’s one thing to think about. Weed growth!

Getting rid of weeds between your block paving can be a long and tiring process, especially if the weeds are well established.

Weed growth between block paving can cause problems to your drive or path. They can move through cracks in the blocks, making them uneven and slippery when wet.

The first sign of weed growth should trigger you to take action!

There are two easy ways to get rid of weeds between your paving that will solve this problem for good.

Weed removal and preventative techniques 

Method #1 Manual weeding between block paving

Now, this may seem like the most obvious choice, but removing weeds manually could be your first step to getting rid of weeds between the block paving.

Using a hoe or garden fork, you can very easily scrape the surface of your path and remove any vegetation growing there.

Make sure you are careful to weed at joints in your blocks as well as on the surface if possible, to ensure that no vents are left for future growth.

Step 1 – Ensure you have a pair of knee pads, only manually pull weeds once it has rained.

Step 2 – Clear away all debris from the surface of your block paving, stones, twigs, etc that might get in the way. Make sure you can weed freely with ease.

Step 3 – Weed at joints in the blocks as well as on the surface if possible to ensure future growth has nowhere to go.

Make sure you go right down to bare dirt where needed. Ensure this is done thoroughly.

Step 4 – Once you have cleared everything away use a garden hose pipe or pressure washer and clear out any remaining weeds and vegetation from between your blocks. It helps to clean and pressure wash at the right time of the year, too.

This step especially should be thorough!

Pat yourself on the back for getting rid of those pesky weeds that were coming through your block paving!

Now you’ve done that, let’s apply some solutions…

Method #2 Use Baking Soda to get rid of weeks in your block paving

Not only isn’t fairly cheap to produce your own baking soda solution, but it is also environmentally friendly!

Baking soda is a natural alkali that helps to break down organic materials, such as weeds.

The idea is to mix baking soda in water to make a solution. The baking soda breaks down the weeds and with enough time, the weed will decompose back into nothing!

There are two options when using this method. You can either pour it right on top of your weeds or you can mix the baking soda in water in a spray bottle and use that for easy application.

Step 1 – Ensure you have plenty of baking soda on hand

Step 2 – Apply directly onto the surface where the weeds are growing

What happens is, you overload the weed and roots with salt causing it to decompose. It’s a slow process, but it works really well!

Method #2 Use Vinegar

Just like baking soda, there’s a high probability that you will have some white vinegar in a cupboard somewhere! And just like baking soda, white vinegar has natural acid properties that can help break down organic matter.

The added bonus is that it also kills moss and algae!

Don’t worry about it leaving your block paving dull; the solution becomes diluted with water after all is said and done.

Step 1 – Measure out half a cup of white vinegar into a container

Step 2 – Mix in two tablespoons of dish soap

What happens here is the dish soap emulsifies the oils on the weed leaves to stop it from absorbing sunlight, which eventually causes death.

It’s definitely one to try if you’re looking for cheap ways to get rid of weeds growing through your block paving.

Method #3 Use both Baking Soda and Vinegar

We have mentioned using baking soda on its own and also vinegar. So how about combining the two to really speed up the process?

Step 1 – Measure 4 cups of white vinegar into a container

Step 2 – Add in 8 tablespoons of baking soda

What happens is the alkali and acid together create an incredibly powerful reaction known as esterification, which helps to break down organic material altogether.

You can use this type of solution for concrete also! It’s definitely worth trying.

Just remember it may take some time for things to happen so be patient! It takes longer than methods #1-3 but works well.

Method #4 Use Salt

Another natural product that can be found in your home is salt! Just like white vinegar, if you have salt already in your cupboard then it won’t cost much to pick up some more.

The idea with this technique is that you are trying to create an environment where the weed cannot survive by overloading them with sodium chloride.

Step 1 – Measure out one cup of salt into a container

Step 2 – Mix in two tablespoons of dish soap

What happens is the dish soap emulsifies the oils on the weed leaves to stop them from absorbing sunlight, which eventually causes death.

So try these cheap options next time you’re looking for ways to get rid of weeds growing through your block paving.

Method #5 Use Root Killers (glyphosate)

A lot of people have been using Roundup to kill weeds in between their block paving.

You can find this in a large hardware store relatively easily. The process is fairly straightforward, but the downside is that it does leave a chemical residue on your slab which you will need to consider when selecting a sealant for your driveway!

Step 1 – Measure out one tablespoon of root killer into a container

Step 2 – Mix in two tablespoons of dish soap

What happens here is the dish soap emulsifies the oils on the weed leaves to stop them from absorbing sunlight, which eventually causes death. And with enough time, the nutrients in the soil become unavailable and your weeds die off long term meaning they won’t come back so quickly next time!

Roundup has received some bad press in recent years, so maybe try the DIY solutions I mentioned earlier, first.

Method #6 Use an Electronic weed killer

Did you know that you can now buy electric weed killers off the shelf in hardware stores to use on your block paving?

The advantages of these weed eaters are numerous. They’re known as “electric weed pullers.”

As a result, they’re “electric weed pullers” that have been created for removing any root weeds ergonomically and effortlessly due to their unique ergonomic grip.

Its long shaft eliminates the need to dig or bend, reducing strain on the body because it reaches from many angles with its deep-reaching stainless steel jaws.

How To Remove Moss From Block Paving

For your block paving, Bleach is also an excellent moss and moss and weedkiller Wipe down the space you wish to treat and wet it.

Sprinkle a 5:1 water-bleach solution over the surface and scrub it vigorously for 15 minutes. Rinse the location with clean water once again afterward.

Note: If you have pets or children, ensure they don’t go near the area for a while (it can take up to 2 weeks for effects to become apparent).

How To Get Rid Of Grass Between Paving Stones

Again, we’re going to use white vinegar and salt. The idea is that the vinegar kills the top layer of grass and then you follow up by salting it to create a hostile environment for weeds and moss (which will try and grow later).

Step 1 – Measure out half a cup of white vinegar into a spray bottle

Step 2 – Mix in two tablespoons of table salt

It’s definitely worth trying this technique, but as I mentioned earlier, it can take some time for things to happen so be patient!

FAQS

Does weed killer kill moss on the patio?

Yes, weed killer does kill moss on your patio. The only reason people think it won’t is that either 1) they don’t use weed killer on their patio or 2) they do use weed killer but don’t see immediate results.
The thing about moss spores is that they are always in the air. If you apply weed killer correctly then it will kill off your moss over time, but this may not happen overnight – you’ll need to be patient!

Does vinegar kill weeds?

Yes, white vinegar can be used as a natural herbicide. So if you have dandelions growing in your lawn or between your paving stones, try using some white vinegar straight from the bottle after measuring out two tablespoons into a spray bottle. You can also spray down any other types of weeds with white vinegar too!

Does weed killer kill grass?

Yes, a weed killer can be used to kill both moss and weeds growing in the same area. So if you’re looking for a professional solution that will take care of all your problems such as grass and weeds between paving stones then look no further than Roundup or similar products containing glyphosate.

How much salt kills weeds?

A lot! If you have a large space filled with weeds, I would recommend using two tablespoons of table salt per one cup of water in a spray bottle after mixing in two tablespoons of dish soap to create a stronger concentration when spraying down your weeds.

Summary

We have just gone over 6 different ideas on how to kill weeds in between paving stones.

The majority of them are quite cheap to put together and only require the usage of household ingredients which you must already have.

I would personally recommend trying vinegar first because it’s super effective for killing grass, weeds, and moss!

Remember, be patient with this process; if you feel like it hasn’t worked try applying these techniques again after a few days (or even weeks).
