Moss is very resilient and can survive under the harshest conditions including under plant pots. If just one spore survives you could find yourself cleaning your patio more often.
This is why we don’t recommend just using a pressure washer without removing all the moss and weeds first, as this will cause spores to break off from the pressure and could end up under an object where the moss could reproduce.
Unlike plants, moss has no roots which means it doesn’t have to be planted in the ground to survive and grow making it very resilient. If you want to know more about this we recommend you read this article Does Moss Have Roots?
2. Use A Metal Brush
So once the block paving has been removed of all objects you need to start removing the moss and the easiest and best way to do this is to use what’s called a weeding wire brush tool.
Using one of these tools will make the process a lot easier and you’ll be able to get in between blocks to remove any moss, weeds, or dirt.
This part is very important as just the smallest amount of moss or weeds that are left behind can start the whole process off again and your find that after a couple of weeks the moss and weeds are growing back.

Now, using a wire brush will take some time depending on the size of your block paving, however, removing the moss and weeds correctly will give you much better results not to mention making your patio or drive look cleaner.

3. Remove All The Moss Leaves
Once all the moss has been removed from in between the blocks and surrounding areas you need to sweep up all of the loose debris and any roots from the weeds.
Remember to take your time with this because as before leaving just one root or moss spore that’s been left behind can just the whole process off again.
Some of these moss spores are very small to see so it’s a good idea just to give the block paving a second going over with the sweep just to make sure you leave nothing behind.
4. Brush Block Paving Cleaner Into The Surface

Some of these paving cleaners are also Bleach-free, biodegradable, and have an unlimited shelf life so if you don’t use all the products then you know it is ok to use for when you need them next.
Although there is a waiting time, the results are well worth it if you want your block paving “moss free” and looking great.

Stopping Moss From Growing Back On Block Paving
Now, this is a hard question to answer because, as before, moss is very resilient, and even if your block paving is free of moss there’s still that chance spores can get blown onto your driveway or patio start to reproduce.
You see, moss has what’s called “Gemmae” on the stems which are designed to break off and form new plants, and because moss is very light these spores are able to travel with the wind.

Moss thrives in damp areas so the best way to stop moss growing back on your block paving is to keep it dry as possible. Making sure there are no gaps between the blocks can also help prevent moss from growing
Although this won’t completely stop the moss from growing back it can limit the amount of moisture in the pavers and joints that moss thrives on!
