Since 2019, many herbicides have been banned for sale to individuals due to their toxicity to health and the environment. White vinegar is composed of acetic acid, the degradation of which in the soil can be as polluting as glyphosate.
Dilute the white vinegar to 20 or 30%, i.e. 200 ml or 300 ml of vinegar for 1L of water. Spray the solution on the stems and leaves. Some gardeners add 200 grams of fine salt to this solution (coarse salt is also effective but it melts less easily)
