Vinegar - a natural weed killer?

Almost everyone has a bottle of apple cider vinegar or vinegar essence at home, after all, the acid is very versatile both in the kitchen and in the household. You not only season food with it, but also remove limescale deposits from the kettle and bathroom and you can even use it for cleaning - which in turn makes expensive chemical cleaners completely superfluous.

The old home remedy is also said to be of good use in the yard and garden Weed removal do and protect the environment at the same time. But is that really true? Does vinegar actually help against weeds? In this article we will explain whether and what is true of this tip - and why it is better not to attack your flower beds with vinegar.

Mode of action

For plants to grow healthily, the acid-base value - the so-called pH value - must be in balance. Since vinegar is an acid, it acidifies the soil and damages the cell membranes of the plants. That is why the household helper in the garden is not entirely safe as long as you use it undiluted and in high concentration.

A small dash of vinegar on a jug of irrigation water, on the other hand, only lowers the pH value slightly and has no negative effects on weeds and other plants. In this way, however, you can make hard water softer and neutralize lime - which is not always desirable in irrigation water. Vinegar is actually advisable for this purpose, but less so as a weed killer.

If highly concentrated vinegar gets into the ground, it not only corrodes the roots of the weeds. Neighboring crops are also affected, so that both can no longer absorb water and consequently dry up. In addition, the soil acidifies when using vinegar, which is why you have to counteract the drop in the pH value with regular lime additions. All these side effects prohibit the use of the product, for example in the vegetable patch or in the flower beds - you would then have to dispose of both together with the weeds.

Vinegar harms weeds and everything else that lives in the soil

These are the benefits of vinegar against weeds

Many hobby gardeners prefer old home remedies such as vinegar and salt, as these are supposedly more environmentally friendly than chemical ones Herbicides are. In addition, various brands of vinegar-based are available in stores for a lot of money, which is why the vinegar essence alone seems to be a good alternative for reasons of cost - after all, it is the effect of the commercial products same. So at first glance, vinegar appears as:

• effective against weeds
• inexpensive
• easy to use
• Safe for children and animals

The disadvantages speak against an application

No question about it, the advantages of vinegar are convincing first of all. However, the acid also has a number of disadvantages that speak against its use. The most important counter-argument is the acid, because this gets through the soil into the groundwater and everywhere destroys the balance between acids and bases. To use vinegar effectively against weeds, you would have to apply larger amounts - and they always have a negative impact on the environment. Other disadvantages are:

• Effect doesn't last long
• Weeds are often only grabbed superficially, but not at the root
• therefore sprout again and again
• therefore the application must also be repeated
• Damage not only to the weeds
• neighboring (useful) plants are also affected and perish

Is vinegar allowed as a herbicide in the garden?

Especially since the use of vinegar in the garden - especially in connection with salt - is also a delicate matter for legal reasons.

For a long time, vinegar and vinegar essence were used as pesticides, provided they were used against weeds and other plants. Because of this, their use was on paved and otherwise sealed surfaces forbidden. Ever since the Higher Regional Court of Oldenburg collected this classification in a 2017 judgment, vinegar has not been valid more than a herbicide - i.e. as a pesticide, but it may not be used indefinitely in the private sector will.

Vinegar is an environmentally harmful pesticide

Both the chambers of agriculture and the environmental protection agencies are particularly opposed to a ban on the use of vinegar to kill weeds Non-cultivated land areas (terraces, garage driveways, parking spaces, etc.) and justify this with a violation of Section 3 of the Plant Protection Act - a "violation of the good professional practice ”. Such can be punished with a fine of up to 175 EUR.

This is not about illogical harassment, but has solid reasons: Vinegar is only biodegradable in small quantities and quickly ends up in the groundwater. However, this is not wanted by the sewage treatment plants, as the vinegar residues cannot be filtered out and also permanently change the pH value of the water.

use

In view of the current legal situation, vinegar should never be used on paved or otherwise sealed surfaces. The remedy has no place in the vegetable patch either, after all you want to eat your harvest afterwards. In general, before each use, check whether there is still a better remedy without unwanted ones There are side effects - you will find a few of them clearly presented in the table below Text. However, if there is no alternative to vinegar, use the old home remedy as described in this chapter.

Vinegar or vinegar essence?

You can get different types of vinegar in the supermarket, each with a different concentration. Conventional table vinegar, for example, contains up to six percent acetic acid, while vinegar essence is considerably more concentrated with a content of up to 25 percent. This concentrated acetic acid can cause chemical burns if improperly handled - not only on plants, but also on your skin. Therefore, in the event of use, you should strictly observe the following safety instructions:

• wear closed eye protection especially when spraying
• use protective gloves made of nitrile or another resistant material
• never use in closed rooms, always ensure good ventilation
• never inhale the spray mist, otherwise burns could result in the respiratory organs
• do not spray in windy weather
• in the event of contact, rinse the affected part of the body immediately and thoroughly with water
• if necessary, consult a doctor (for example, if vinegar essence gets into the eyes)

Apple cider vinegar, which can also be used to remove weeds in the garden, is considerably milder. However, that does not mean that this type of vinegar is less harmful to the environment.

Mixing ratio

Vinegar should never be used undiluted

You should not use vinegar more than twice a year and only in a concentration of 100 milliliters of table vinegar in one to two liters of water. This amount is also the maximum amount that can be applied per square meter of area. Incidentally, the self-mixed weed killer works better if you boil it before use and pour it hot over the weeds. In this way you combine the action of acetic acid with the thermal one. Also add a few dashes of washing-up liquid to the mixture so that the vinegar mixture does not simply roll off the leaves.

Best time

It is best to apply the vinegar in sunny and dry weather, because rain would simply wash the agent off the leaves again. In addition, the sun intensifies and accelerates the effect on the weeds to be eliminated. You can do this very nicely by making a direct comparison between growing in sunny and shady locations Observe weeds: With shade plants, it always takes a few days longer for the leaves to turn yellow and finally dry up.

Incidentally, vinegar can be saved well by cutting off the above-ground parts of larger plants and simply dousing the remains with the solution. In this way, you need much less of the agent and thus protect the environment.

Advice on applying vinegar against weeds

The following tips are also helpful when using the vinegar:

• only spray on from a short distance
• it is best to apply it specifically with a brush
• only use in spring and summer
• only treat young plants before sowing
• also remove seed heads by hand
• always use as small an amount as possible
• never spray in windy weather

The combination of Vinegar and salt is touted by some hobby gardeners as an insider tip against weeds - but be careful! If the use of vinegar is a legal gray area, then the use is of salt in the garden is strictly forbidden and can be fined up to 50,000 EUR will.

frequently asked Questions

I've heard that baking soda is great for weed control too. Is that correct?

Our grandmothers used baking powder to tackle stubborn weeds. To do this, mix two to three packets with five liters of water and pour the mixture over the plants to be removed. But be careful: Firstly, the trick does not work with all baking powders, but only with baking soda, and secondly, this also differentiates Means not between weeds and crops: All are simply destroyed, and there is also an unfavorable influence on the pH value.

My grandma recommended Cola for the weeds in the paving stones. Does that actually help?

Indeed it is cola Due to the phosphoric acid it contains, it is an effective means of removing moss from paving joints, for example. The disadvantage, however, is that the agent is extremely sugary and therefore sticky at the same time. So you don't save any work because you do
