Effectiveness of a Homemade Vinegar Weed Killer
Small, annual weeds are the best targets for a vinegar mixture. When dealing with perennials, grasses, or elder weeds, its effectiveness decreases. Even after soaking the roots of the more resistant weeds with your own solution (best done in the autumn), you may still not see much of an improvement. Keep in mind that you’ll need to apply this solution multiple times because it only kills the tops of the target weeds, not their roots, which can regenerate new shoots.
Appropriate Use of Commercially Available Horticultural Vinegar
The most effective approach for eradicating persistent weeds is a vinegar solution of 20% or 30%. Garden centres, farm stores, and even online vendors provide this vinegar kind, which goes by several names including horticultural vinegar and herbicidal vinegar. Because of its significantly larger acetic acid content compared to regular home vinegar, it is an effective treatment that, with repeated applications, can eradicate even the most tenacious weeds.
How to Use Vinegar Weed Killer and When to Use It
In spite of your best efforts, vinegar—whether you use horticultural vinegar or concoct a DIY solution—is non-selective and will harm any plant or grass it comes into contact with, not only the weeds. So, driveways, mulch or gravel paths and spaces between sidewalk concrete joints are ideal for applying vinegar weed killer. To avoid spraying vinegar on other plants, it is best to apply it in these specific regions.
When using this weed killer, as with any other, wait for weather conditions of 70°F and sunshine. During the photosynthetic process, the chemical will have the most impact on plants. Stay away from days when it’s going to rain or be windy. The vinegar can end up where you least want it if the wind carries it. Its efficacy is reduced when it rains.
To use vinegar as a weed killer, approach the weed closely and spray the leaves directly. Do not spray again for at least two weeks.
There will be a noticeable explosion of salad dressing aroma in your yard for a few days after you apply the vinegar weed killer. To be fair, that strong aroma may temporarily keep rabbits, deer, and other pests off of your plants.
Ways to Prevent Vinegar Weed Killer from Infecting Other Plants
Be careful not to spray any neighbouring plants with the vinegar as you aim it at the weeds. To be extra cautious and not let it spread, use a brush to paint vinegar into the weeds, making sure the vinegar touches all of the leaves. If you’re trying to eradicate weeds in your garden or lawn, don’t use vinegar. It is recommended to use mulch or other measures to manually eliminate weeds from certain areas.

Is it OK to use vinegar as a weed killer on various surfaces?
Avoid spraying vinegar near planters or patios made of wood or marble, as it is acidic and can harm these materials. Confidence shouldn’t be harmed.
Will regrowth of weeds be prevented by vinegar?
