Why should you be wary of the wide range of synthetic weed killers?
Actually, synthetic or manufactured weed killers available on the market are useful and pretty safe solutions when you wear full of protective items. But, you should be wary of these chemical concoctions in gardening due to the following reasons:
Allergies or sensitivities
Do you have any chemical sensitivity from an allergy or asthma?
If yes, you must be more careful because they may put you in danger. While applying, wearing protective items is a must-thing to reduce irritating. They include a mask for your face, a pair of gloves for your hands, long clothing for covering your legs and arms.
Nowadays, the majority of families have pets who love walking and playing in your garden or backyard. Thus, using synthetic weed killers may put them in danger.
If your pets lick greenery sprayed with commercial weed killers, it will lead to illness. That's why I write this vinegar weed killer article, which is a safe solution for your lovely pets.
Can vinegar kill weeds?
Of course, yes. Even vinegar is one of the most effective and safest natural ways to kill weeds.
Why should you choose vinegar to kill weeds?
Due to the risks above, you need an effective natural alternative. In this part, I will let you know why you should choose weed killers with vinegar:
First of all, although there are several natural weed killer ingredients, vinegar is always the safest choice for your pets, kids, and our environment. Make sure that you apply enough concentrations or quantities.
For annual plants, the standard kitchen vinegar is strong enough to remove them. However, if you need to deal with a severe weed problem, I strongly recommend you use horticultural vinegar with higher acetic acid.
Keep in mind that the vinegar works best on sunny days since rain can wash your vinegar away. Furthermore, sunlight is also an essential catalyst for the best outcome.
Is horticultural vinegar a safe solution?
Many people said that the horticultural vinegar is more effective in killing weeds than distilled vinegar.
Is this true?
Yes, but this kind of vinegar should be used with caution because it modified from the production in the labs with high acetic acid concentration.
When it comes to strength, this kind of vinegar is stronger than other vinegars many times. Specifically, its 20% acetic acid concentration is more than 5% compared to household vinegar.
Thus, before applying, make sure that you wear protective goggles and clothing. It's better to mix this kind of vinegar with water for diluting.
The concentration of over 11% of acetic acid can burn your skin and damage your eyes. Meanwhile, the concentration over 20% can corrode concrete, iron, aluminum, tin; even it causes blindness. So, WEARING PROTECTIVE THINGS IS A MUST. Moreover, animals and our environment are also in danger.
Do you need special vinegar to kill weeds?
The short answer is yes because some of them won't work. You should look for vinegar with high acidity (about 10%, even 20%) since acetic acid plays an essential role in killing weeds.
I don't recommend regular old household vinegar that has 5% acetic acid only. This number just can wilt the weeds, and after a short time, they will regrow. The worse case is that it does nothing.
How does vinegar work to kill weeds?
Basically, the acetic acid in non-selective vinegar can kill any plant, no matter what the source is. After absorbing the moisture from the weed leaves, the weeds die quickly. Now, your task is to shrivel the weeds.
Vinegar can kill any part that it touches, but it doesn't work well with deep roots. Therefore, after a long time, they can regenerate from deep underground.
Is it safe to use vinegar as a weed killer?
In general, it is safe. But, if you use vinegar with a higher concentration of acetic acid, it is hazardous.
Keep in mind that 10-20% acetic acid vinegar is enough to kill the weeds.
While working, don't forget to wear protective items to keep yourself from danger: eye gear, safety gloves, and face masks.
In some cases, some people were burned as they stuck their hands on a grill when killing weeds on bare skin.
One more note:
Don't overuse vinegar since its acid content can alter the soil PH, preventing the development of your plant in the future.
What are the advantages of vinegar as a commercial weed killer?
Here are what you will get when using vinegar as a commercial weed killer:
- A cheap and readily available solution
- Quick to eliminate small weeds
- Safe for your pets, kids, and our environment
- Removable for most weeds in one application
What are the disadvantages of using vinegar?
Anything has both positive and negative aspects. You should learn carefully to make sure that it suits your case:
- Higher acidity for more dangerous
- Not useful for deep-rooted weeds and plants
- Not suitable to use on your lawns
- Not useful lower acidity vinegar
- Harmful to soil PH
Do you need any tool to use with vinegar?
To apply a large area of weeds exactly, you need a sprayer bottle or pressure sprayer.
Of course, you also need to prepare some protective items for your hands, eyes, and mouth.
