Vinegar is very effective in the garden. If you use vinegar weed killer can help control weeds around your environment and they are less harsh on the environment than many synthetic herbicides. But you should not use the acidic liquid in all areas of your landscape because it could damage any plant it touches. It is an effective herbicide that contains acetic acid which can kill plant cells.
How you can kill weed and grass with vinegar are as follows:
Spray the vinegar on the weed on a sunny, hot day as that is the most effective way to use vinegar.
A 5% solution of vinegar is generally considered effective, but stronger concentrations may be needed for stubborn weeds.
Be careful when applying vinegar, as it can also damage desirable plants if it comes into contact with them.
Vinegar works best on young, actively growing weeds.
To improve the effectiveness of vinegar, add a few drops of liquid soap to the solution, which helps it stick to the plant and penetrate the waxy cuticle of the leaves.
Repeated applications may be necessary for stubborn weeds, but be careful not to overdo it, as too much vinegar can harm the soil by lowering the pH.
