How to get rid of weeds on paving

[hopeishere]

How can I get rid of these weeds permanently? I jet washed the area a while back and put in what was supposed to be weed suppression filler between the pavers but they returned.

I'm reluctant to use a weed killer as the dog is out here all the time.

Try boiling water poured on them

Whatever you do is unlikely to be permanent, nature will take any opportunity to grow. I have over 50 years of experience to back that up!

One way, which won't harm your dog, is to pour boiling water on them. It will mean filling the kettle a few times but is quite effective. It is probably just as effective as scraping them out with a special hook. You can also get a long handled tool which can burn them off.

It's the Great Outdoors. Nature will find a way to keep growing wherever it can find a foothold.

Just pull them up or use a sharp and pointy vegetable knife to winkle them out. If you sweep the area with a stiff yard brush regularly, you will get rid of them as soon as they poke their noses up.

Gas weed burner, I use one for same reason, don't want to poison pets. But you have to be persistent, if it's a small area a quick blast around when you see them coming back does the job. Weed killers are never permanent either.

That looks like block paving. If it is, the weeds are not coming up from underneath, but are growing in the cracks and indents on the top. This is annoying, but means they aren't deep rooted. You can get a wire brush on a long stick to clean the joints. This method gets rid of the detritus that the weeds take root in as well.

Otherwise, dishwasher salt works a treat and won't hurt animals.

I would never have got block paving if I'd known how much work it is to maintain.

Salt is bad if it gets in water courses and poisons the ground for all plants if it gets on the soil.

If you jet wash it,put new sand in you can minimise any weeds by using a block sealant like resiblock.

It coats any sand and makes it very hard. Ants will still makes gaps but weeds will not take root in the gaps.

Did mine just before lockdown and barely a weed since.

I was going to say this too. They are very satisfying to use. and you can buy cheaply at Home Bargains or they come in the specials at Aldi/Lidl in the Spring.

What you appear to have there is annual weeds. They have tiny seeds and are very shallow rooted so they just grow anywhere. Once you've got rid of one lot, another lot pop up when you turn your back.

I get them in my gravel which has a good four layers of decent weed membrane underneath (as I've learnt my lesson on that before).

If used sparingly, it's better than chemicals. Harsh chemicals anyway.

Thanks everyone. I LOVE a gadget so a gas burner sounds fab!!
