Use Vinegar & Salt as a Weed Killer


Weed killers or herbicides are chemical substances that control unwanted plants or to control unwanted weed species. There are selective and non-selective herbicides. Selective herbicides help you to control a specific plant and non-selective herbicides act against any plant that come in contact with.

Tips on using weed killer safely

Use Vinegar & Salt

While using weed killer, remember these tips to be successful and safe.

  • Weed killer does not work well with high concentration. So, make sure you do not use heavy dose. Instead, use light concentration and spray several times.
  • Weed killers take some time to work and thus you must wait before reapplying this substance.
  • It is advisable to go for natural weed killers to keep your lawn or ground safe.

Vinegar has gained a fierce reputation as a weed killer. Just like most commercial herbicide out on the market, it is a non-selective weed killer (it kills any plant it comes in contact with). What separates vinegar from other commercial weed killer is that it is environmentally friendly, so it will not harm people, pets or the environment.  One of the major reasons why a lot of people don’t use vinegar a lot is that it has zero residual action, that is, it only kills weed it comes in contact with, so, any new weeds will not be affected.

To permanently remove weed from your gravel drives, path, cracked wall, and walkways, sprinkle salt to obliterate them for good. When applying a salt and vinegar solution you must be careful not to pour it on the soil directly.

The role of salt as a weed killer

Vinegar mostly targets the potion of a weed that is above the ground, but salt gets to the weed roots and acts as a desiccant, drawing water from the plant until the plant dies. But there is a risk when you add too much salt. If you add too much salt in a natural weed killer recipe, it will prevent anything from growing in that location for a very long time. So, when adding salt to your herbicide recipe, do it moderately.

The role of vinegar

White vinegar contains a 5% level of acidity which is perfectly fine for making a natural herbicide. Vinegar is a non-selective weed killer, so anything it touches will die.
