Vinegar is a popular natural weed killer, and many different types of vinegars are used for this purpose, including white vinegar, rice vinegar, red vinegar as well as apple cider vinegar. Vinegar’s lethal ingredient, acetic acid, damages plant foliage and dries it out. Normally, the stronger the acidity level of a vinegar, the stronger the vinegar’s weed killing power will be. This is because it’s the acetic acid in vinegar which works to kill weeds.

Bleach: Bleach is useful in killing mature weeds, place some bleach in a spray bottle and spray on the weed you want to kill. The following day, pull out the dead weeds.
Sugar: Sugar is also a natural weed killer, because it puts the soil organisms into overdrive and the soil becomes temporarily unsuitable for plants. You can simply pour some sugar at the base of the weed you want to kill.
Cornmeal: Cornmeal contains a chemical that acts as a pre-emergent on plant seeds. That means that you even can stop the weeds before they appear with the help of cornmeal.
