How to use white vinegar as a weed killer?
Usually, white vinegar is 5% acetic acid and 95% water. While it is used as a weed killer, it has pretty some limitations. It can work properly with small annual weeds that are around two weeks aged. At the same time, it will need some ingredients to succeed in the field. Additionally, you can increase its efficiency by adding a tablespoon of liquid soap, a cup of table salt, with a gallon of white vinegar. Usually, this mixture destroys the tops of the target weeds and keeps avoiding the roots that may regrow new shoots.
Household vinegar can’t work expectedly while applied on older weeds, grasses, or perennials. Killing older weeds, perennials, and grasses 20% vinegar solution is appropriate, called horticulture vinegar, may be found at garden centers, horticulture centers, farm stores, and online.
The safest place to apply vinegar on weeds is concrete seams such as footways, driveways, mulch, or gravel paths. Spraying vinegar in these areas is usually easy because you haven’t got contact with other plants. Like any weed killer, choose a warm and sunny day to spray it. Be aware that wind can flow the vinegar to the areas you don’t want to use. Further, the rain minimizes and dilutes its effectiveness.
When applying a high concentration of vinegar, ensure the safety precautions like other herbicides. Please keep away from touching it on your skin or eyes and never ingest it. This higher concentrated vinegar may burn skin, damage eyes, as well as cause bronchitis if inhaled.
Vinegar is a non-selective pesticide, which means that it will harm not only weeds but also any plants and turfgrass it gets. As a result, before spraying onto weeds, be aware that it doesn’t touch the other plants. If it isn’t possible, use a brush to paint the vinegar onto the weeds. Meantime, ensure the vinegar gets in contact with all the foliage. The acetic acid assists in burning and fading out the leaves.

5. Spray directly onto the weeds
By using a spray bottle or pump sprayer, completely douse the weeds that you want to destroy. Cover the foliage parts and spray around the roots area. After 24 hours, if you can’t satisfy, respray a second time.

- Smoothly stir the soap into the vinegar, but avoid shaking the bottle too much.
- It isn’t essential to accurately measure the dish soap; take an amount close to a teaspoon per litre.
3. Affix 2 cups of table salt to a gallon of vinegar. Though salt can’t affect all weeds, it may dry out some weeds quicker than ordinary vinegar. Add 2 cups (473 ml) of salt per gallon (3.8 L) of vinegar. You may add it to the mixture that contains dish soap before. Use inexpensive table salt instead of Epsom salt, rock salt, or sea salt.
- Salt usually remains in the soil for a few days and creates a long-term effect on healthy plant life. So, before applying to the desired area where you want to plant again, it would be better to skip the salt.
