Keeping a vegetable garden or garden well-kept involves eliminating the “weeds.” Make your own herbicide at home with natural products.
Keeping an orchard or garden in perfect condition involves eliminating weeds. It is true that when we hear the word herbicide, the first thing that comes to mind are chemical substances, but it does not have to be that way, since herbicides do not have to be a poison.
There are many household alternatives to commercial herbicides that are so toxic to the environment, our pets, and ourselves. And we will not have to worry about our cultivation, as it will not suffer any damage. Pay attention, we show you how to do it in this article.
Homemade herbicides to kill weeds
There are seven ways to make homemade and natural herbicide to kill weeds.
1. Boiling water
A simple remedy like boiling water is a powerful herbicide. In addition, it is as easy to use as putting a pot of tap water and heating it up to the boiling point. Then carefully pour it over the weeds you want to remove.
It is a very effective way to eliminate weeds forever, but be careful because boiling water does not select, so apply it only on the plants you want to get rid of, otherwise you will kill other plants nearby.
Dihydrogen monoxide or boiling water will instantly kill anything it reaches, including the underground roots of nearby vegetables. Furthermore, it is the least harmful herbicide for people and the environment.
Salt is one of the best herbicides for weed control. In fact, if you want no weeds to grow back in an area, we just have to add salt. This solution is ideal if we have a tiled path and we do not want plants to grow in the middle of them.
You will have to renew the sodium chloride or salt from time to time, so you will have the assurance that weeds will not grow, but not good ones, so keep that in mind. This effective herbicide has historical precedents, as it was used to devastate the soils of conquered towns to prevent plants from growing there.
It is because of its harmful effect on the soil that it is advisable to apply it on the leaves of the weeds, and not soak the entire soil. In these cases, dissolve one part salt in eight parts hot water, add a pinch of liquid soap to help it adhere to the leaves, and pour the mixture into a spray bottle. Cover or tie off adjacent plants you want to keep and spray weeds with this solution.
Whichever variety of vinegar you use will work to remove unwanted vegetation. However, afterwards you must use a weed extractor, even if it is your own hands. This is because acetic acid will kill the leaves of the plants, but not their roots, it also works better in young plants because they do not have enough strength.
We can even make this herbicide more powerful if we mix a liter and a half of vinegar, the juice of a lemon and a tablespoon of dish soap. Also, if you spray the weeds with it with the help of a sprayer during a sunny day it will be much more effective.
White vinegar has about 5% acetic acid, but there is a more industrial version that can contain up to 20% . Be careful with this as it could be harmful to your skin, eyes and lungs.
4. Corn flour
Without a doubt, after using a weed remover, this is one of the best herbicides for weed control in a garden, if not the best. And it is as simple as spreading cornmeal on the ground and nothing will grow under it, because it acts as a kind of nullifier of the seeds.
It is best to wait for your seeds to germinate to ensure that the cornmeal does not harm your planting. Next, use a weed extractor and when there is not even a bit of flour left, then the weed seeds will not sprout.
Another homemade method to eliminate weeds is to place several sheets of newspaper on the areas where we want to eliminate them. On top you can add more soil so that the paper is not visible and no plants will grow, since the absence of sun will prevent them from germinating .
6. Lethal mixtures
If your orchard or garden has especially strong weeds and you cannot kill them with the application of these natural remedies, you can create more powerful herbicides for weed control by mixing some of them.
For example, you can mix salt and vinegar to ensure quick and effective results, but keep in mind that for a certain period of time you will not be able to plant anything where you have used it. You can also mix boiling water with salt or vinegar, or both, a mixture that will clean your garden of weeds.
Lastly, borax is sold as a laundry and cleaning product, but you can also use it in your garden as a herbicide. To do this, add 280 grams of powdered borax to 2.5 liters of water, mix well, and pour it into a spray container to cover the leaves of unwanted weeds.
You should consider that the fact that these herbicides are natural does not imply that they cannot harm your soil, your garden or yourself. Herbicides for weed control are still toxic to plants and could have a negative effect on the soil if applied in large quantities, as well as could cause injury if used incorrectly, so be careful.
The most environmentally friendly way to get rid of unwanted plants is to use a weed extractor or pull them up, dig up the roots, let them dry in the sun and then add them to compost.
