Weeds in pavement joints look ugly and can even lift the stones. Regular cleaning is necessary, but my tips make it easier.

It has not only happened once that visitors enter our property and look at us enviable looks because of its size. Yes it is true, what we have created in recent years is quite handsome, but it also does a lot of work!

After I recently gave you a few tips on how to free your terrace from moss and greenery, we will now take a look at the entrance and all the other paved areas. It annoys me enormously when I come home from work, open the gate and a carpet of moss and weeds, neatly distributed between the joints of the paved driveway, awaits me. You know that? Then you are exactly right here.

Clean pavement joints by hand

Whether garden or home owner, most of the work is still done by hand. In principle, it is also a nice balance to the job, as long as it remains in moderation. Flushing weeds out of the pavement joints is certainly one of the less pleasant things.

»Scratching joints without stooping«

I don't know how you have tackled the "weed infestation" so far. I made my first attempts with a sharp knife from my household. I could throw that away afterwards.

In the meantime I have a real joint scraper, with which I am also very satisfied. The small models, which are between 20 and 30 cm long in size, also do their job, but literally bring you to your knees. 😉 My choice therefore fell on a joint scraper that can simply be placed on a normal broomstick (see So I can get to work standing up and the result is great. Since I rarely film myself at work, here is a sample video so you know what I mean.

Remove weeds in pavement joints with gas

To save annoying weed picking, large areas in the garden are simply covered with bark mulch. Of course this is not possible on paving stones. Alternatively, you can use gas to clean the joints. That sounds dangerous, but it is not and also more ecological than the chemical club.

The weed is made easy by the flame device (see weed burner article) burnt, But only on the surface. Roots remain between the joints and eventually sprout again. This variant of removing weeds from the pavement joints is also somewhat more expensive, since a gas bottle is also required for the gas burner. When you have finished with the area, the flamed weed only has to be swept away and a (for now) clean entrance remains.

Clean pavement joints with high pressure

Everyone has to decide for themselves whether the purchase of a high-pressure cleaner is worthwhile. In the long run, it can make sense, because it not only cleans paved driveways, but also your garden furniture and even the mossy house wall. I don't use the Kärcher quite as often, because the "mess" afterwards is always too big for me. Yes, it is true, with the power of the high-pressure cleaner you also get pavement joints clean, but it also takes a while until the water used for it seeps into the ground and the driveway is dry again.

A clear plus point for the high-pressure cleaner: you kill two birds with one stone. Due to the precise jet, the complete force acts in the joints and "lifts" the weeds. Thanks to a special attachment (see also test report on, the paving stones can then also be “polished” themselves.

Ultimately, as with the gas burner, the joints are only removed from the weeds superficially and thus temporarily. The joint scraper variant presented first is more effective in the long run.

Potato water: natural weed killer

No matter which "tool" you use to clean your pavement joints, the unpopular green will eventually come through. If you spot small spots, you can fight the weeds with normal potato water. It is important that the water is still hot and salted. Then pour directly onto the affected joints and leave it there. The salt and high temperature are "poison" for the weeds, but their cobbled driveway doesn't matter.
