Vinegar + Salt = Organic Weed Killer!
Written By: Micah Wilkins
Can you really use salt and vinegar to kill weeds?! Oh ya you can, learn how below!
Vinegar is an organic and biodegradable method to killing any unwanted weeds, but it will only kill back the plant(kill the leaves but not the root).
Salt, on the other hand, not only kills plants but can also make the ground unsuitable for future plant growth. However, on a smaller scale, a pinch of table salt can be dropped at the base of the plant to kill it, but will dilute down to harmless after a few rainfalls.
So it makes sense that the combination of salt and vinegar would be an excellent weed-killer!
Here’s a recipe for the salt + vinegar weed-killer:
1.Mix 1 pound of salt with one gallon of 5% acetic acid white vinegar.
2.Stir until the salt dissolves.
3.Mix in one teaspoon of liquid soap or two ounces of molasses to act as a surfactant.
4.Spray the foliage thoroughly or inject into the crown. You may have to repeat in a few days.
According to the website ghorganics.com, to concentrate the weed-killer for effective spot application, get a syringe and inject the solution into the center of the vegetation that you want to get rid of. For larger areas, however, apply the liquid with a spray bottle.
Vinegar is an effective homemade weed-killer mainly because of its acidity. Acetic acid, like most strong acids, is a desiccant. That means it removes moisture. When sprayed on plant foliage, the water in the leaves is drawn out, and the top growth of the plant is killed. Whether or not the root is killed depends on the type of plant and its maturity.
The strength of the solution of acetic acid determines how fast and how completely it will kill weeds. Full strength vinegar, not diluted with water, will be strongest. Vinegar with higher acidity is available, but is not commonly found everywhere. However, vinegar with a higher acidity should be handled with more caution, as it is more harmful to people as well as plants.
Vinegar is not selective when it is sprayed on plants. It has the potential to kill any and all foliage. This means that if you spray weeds in your lawn, your grass will die as easily as the weed. As a home made weed killer, vinegar will have limited application, and will require that valuable plants be protected.
However, some plants may be more resistant to absorbing the vinegar. Leaves with a waxy or hairy covering may absorb less of the solution and suffer less damage. And some plants may die above ground, but send up new growth from the root.
This is why salt is a perfect mate for vinegar. It does the job that vinegar is unable to complete. It kills the unwanted plants at the root, while the vinegar kills the foliage.
