Garden lovers or property owners are annoyed by the same weed (or rather weed). Weeds on the sidewalk are particularly difficult to remove because there is little space between the joints. However, there are simple home remedies that can help here.
Salt is widely used and practically always available. But what is this home remedy all about? We explain how salt works as a weed killer, but also what the risks are.
With salt against weeds - how it works
If you want to tackle the weeds in front of your house with salt, do the following:
- Prepare a saline solution from water in which the salinity is about ten percent
- Then apply the solution to the affected areas on the sidewalk
The walking area in the garden remains free of weeds and also looks very neat. The salt solution can be sprinkled into even the smallest gaps in the pavement slabs without damaging them.
But there are also risks associated with the use of salt. In the following we present them and show some alternatives.
Salt as a weed killer: effective, but not recommended
Yes, the salt solution works, that is undisputed. Nevertheless, experts and we, as authors, advise against salt. The salt penetrates into the soil and changes the conditions in the earth and in the groundwater. In addition: Salt is officially prohibited. Section 6 of the Plant Protection Act regulates which means are permitted and prohibited. For home and garden owners, pesticides are not allowed on all open spaces that are not used for gardening. This affects all paths and places around the house. Salt and other home remedies, such as vinegar, are also prohibited. There may even be large fines.
Alternatives to salt as a weed killer
What helps if weeds sprout between the pavement joints and along the way but you want to avoid the harmful salt? Weeding is a tedious job, and it does not remove weeds permanently, the roots are often very deep and are difficult to pull out.

Hot, preferably boiling water is completely harmless to soil and groundwater. This will completely destroy the roots of the plants. The various weeds die and can be completely removed from the ground. Simply pour the hot water onto the weeds. Then let it dry well, then pull out the plants.
Flaming works just as well. You do the so-called “thermal weed killing” with a flame thrower, also called weed burner. Flaming permanently destroys plants and roots, so that you have weed-free paths and seats for a long time.
Conclusion: Salt is no better than chemistry
If you want to do without chemical pesticides, it is better to choose another alternative than salt. The home remedy is effective, but it also poses environmental risks. In addition, the use of salt is officially prohibited. It is therefore better to use hot water as a home remedy. If this seems too tedious to you and you want to control weeds on larger areas, flaming is the best method.
Larger pavement joints can also be planted wonderfully and thus naturally displace wild herbs.
