Gardening: how to weed naturally?

Prohibited since 2019, synthetic chemical weedkillers have the distinction of polluting the environment, but also being potentially dangerous for animals that colonize gardens.Here are 10 natural and effective alternatives to these products.

Sommaire

Since 2019, the Labbé law has banned the use of synthetic chemicals for the maintenance of green spaces, roads, walks and forests open to the public, but also private gardens.Also, the ideal is to find so -called “natural” solutions to maintain the gardens and get rid of herbs that sometimes clutter the aisles, but which can also request the proliferation of insects and diseases that are not welcome invegetable gardens.

As a preamble, it is important to specify that the areas you will deal with must be dry, and that it is better to pass the weedkiller in the morning, in a clear time and when there is no risk of rainin the coming days.Favor as much as possible the mechanical uprooting which also allows you to best target the species you want to eliminate.Before dealing with the natural weedkiller, cut the “bad” plants as much as possible so that the product you will differ is as effective as possible.

We exclude our natural weedkiller recipes all the solutions that contain salt and washing liquid, because they can be harmful to the environment: salt stagnates for a long time in the floors and, just like dishwashing liquid, it can kill smallanimals that colonize the land.

Mechanical and regular uprooting

All the ecological gardeners will tell you, there is no better way to get rid of weeds than by using a little elbow oil.Also, as soon as the plants appear, they must be torn out, because the vegetation over 10 cm high cannot be weeded with a homemade solution or recipe.

This mechanical uprooting also makes it possible to better target the plants you want to keep.Know, for example, that it is precious to keep dandelions because they promote the appearance of bees, precious allied with biodiversity.

In prevention, brushing terraces and alleys is the best way to eliminate seeds before they germinate.If the herbs are too present on the terraces, it will then be necessary to consider redoing the joints between the slabs.

The boiling water

Nature hates heat when it reaches very high temperatures.The eco -friendly trick is therefore to throw water that you have boiled just before on the areas you want to weed.You will still have to repeat the operation as many times as necessary, over several days, until weeds disappear.This technique is to be used only if your kitchen is not too far from weeds: the water must remain really boiling to be effective.

Cooking water of pasta and potatoes

This is another non -toxic technique used by eco -responsible gardeners.Here we combine the heat of the cooking water of pasta or potatoes with starch.On the one hand, hot water will weaken the plant, on the other the starch will plug the pores of the plant and therefore suffocate it in the medium term.A very good combo, to make only cooking water does not contain salt, because it is very tenacious in long -term floors and toxic for the biotope of a garden.

White vinegar

White vinegar is also renowned for its weeding power.For maximum efficiency, choose a vinegar with a high acidity rate at 20 °, and use it pure.This tip should not be used on terraces and paves, Carle White Vinegar kills microorganisms and alter the pH: you risk seeing foam proliferate instead of weeds.

Spray the white vinegar in your aisles and borders and repeat the operation over several days until all the weeds are dead.

Use a caliper

It’s not just the hoster to weed!The stirrup is a very good gardening tool to have in its shed.It looks like a small scraper, sharpened on its two sides, mounted on a long wooden handle.With this tool, you will be able to scrape all the borders and aisles back to mechanically and properly weeding your garden.

Use biocontrol products

Since the Labbé law, manufacturers no longer have the right to offer gardening chemicals, especially those based on glyphosate.You will then find approved weedkillers which are made up of acetic acid and pelargonic acid less dangerous for the.These phytopharmaceutical products are to be handled with care: wear gloves, a mask and glasses to protect your skin and your mucous membranes.

Cover

The tarpaulin is certainly one of the most ecological solutions.With this method, you do not introduce any substance into soils and even promote the appearance of species (earth glasses, larvae, insects) which will participate in the ventilation and nutrition of your land.It is useful for extended, well -defined surfaces and the areas of the garden that accommodate the most living plant species.You can also cover terraces or lessons.Be aware, however, that he will have patience and wait 2 to 3 weeks for all plants to die.There are gardening tarpaulins in all dedicated shops.

Use a thermal weedkiller

Since plants do not like heat, you can also get a thermal weedkiller.They operate on gas or electricity and diffuse a very strong heat that will kill bad plants.Effective from the first passage for the smallest herbs, you will undoubtedly have to repeat the operation ten days later on the most resistant plants such as jack or ivy.Thermal weeding is very ecological, it does not alter the floors.Many organic market gardeners use it and are satisfied with it.Price forks vary between 40 euros (for those with gas) up to 80 euros (for electric models).

Snack

And why not replace, in some areas, weeds with ground cover plants which will then be your best allies?These perennial plants will offer a nice spectacle throughout the year and have the advantage of limiting the proliferation of unwanted plants.Ivy Bellecour, fragrant aspérule, epimediums can thus be sown.Find out beforehand about their planting condition: some like shadow, others await the sun and the heat.

Think of citrus essential oils

This is probably not the most effective solution, but you can still use essential oils on the smallest and less invaded surfaces by weeds.

In a bowl mix 20 drops of essential oils of lemon, orange, mandarinier or grapefruit with a teaspoon of liquid black soap.Then place this mixture in a sprayer filled with hot water and mix well.

This solution is to be sprayed on weeds, it will be necessary to repeat the operation two to three times, every two days.
