remove weeds

When the carefully maintained flowers are overgrown with weeds, some gardeners will want a simple solution. Unfortunately, neither the vinegar bottle nor the salt shaker offer such, but damage the garden soil in a forbidden manner and make any existing in the garden imbalance (the weeds sprout only excessively) in the long run at most worse. Learn how vinegar and salt work on plants and how you can better combat unwanted growth:
Do vinegar and salt help against weeds?
Vinegar and salt can destroy plants, in sufficiently high concentrations they can kill almost every living being, that's how it works:
1. This is how vinegar affects plants
  • Every organism only works permanently if its acid-base balance is in balance
  • You can kill a human by lowering the blood pH by 0.33 pH meters (from the average of 7.33 to 7.0)
  • Half of a rat population dies when consuming 3310 mg (= 3.31 g) of anhydrous acetic acid per kilogram of body weight
  • Because a rat weighs only 300 g on average, 1.1 g is enough as a medium lethal dose (which a rat will never consume)
  • The numbers show very well that vinegar is not always harmless to organisms
  • Humans and rats are equipped with highly intelligent buffer systems as highly developed organisms
  • The plants are not available to the same extent...
  • Vinegar causes weeds to die off when it is taken up with the water in the leaf veins
  • It penetrates the cell membranes of the plant and damages them
  • Almost all plants can survive in the long run only in soils with pH values ​​between about 5 and 7
  • And are poured with water whose pH is around 7
  • Vinegar has a pH of 2.5, so it can thoroughly kill the plant's acid-base balance
  • A little vinegar in the irrigation water is not enough, which makes the water just a little soft
  • The concentrations of acetic acid that kill plants have considerable potential for further damage
  • The PH value in the soil decreases, which damages the fine roots of all plants in the environment
  • They can absorb neither nutrients nor water to a sufficient degree and can simply dry up
  • What vinegar can do well illustrates the article;art676,293326, in which the destruction of two bladders, a birch and a tulip tree through a Stop with diluted vinegar essence is described.
2. How salt works on plants
Even with salt, living plants can be transformed into dead plants, in principle also by a kind of drying out:
  • The semipermeable plant cells absorb saline just like irrigation water
  • Cells are always balanced, substances in the cell should be present in the same concentration as in the environment
  • So when saline floats around her, the cell wants to increase the salinity to make it balanced
  • Salinity is increased by cells by expelling water
  • The plant cells therefore virtually dry themselves out when they are cast with saline solution
  • Bottom line: The cells shrink and the plant comes in
Is the use of vinegar and salt allowed?
Using vinegar as a weed killer is by no means always and everywhere allowed:
  • Some organic acids are authorized as plant protection products
  • Five pesticides currently approved for home gardening contain acetic acid as the active ingredient
  • They are approved for outdoor use against annual monocotyledonous and dicotyledonous weeds
  • But only on paths / places with woody plants, for pome fruit, stone fruit, ornamental shrubs, as a single plant treatment from the 2nd year
  • And only 2 x per growing season and year, at intervals of 7-14 days, not more than 100 ml / m²
  • Also on lawn moss, twice a year at least 40 days apart, as a surface treatment, max. 100 ml in 2 l water / m²
This applies only once for commercial weed killers with acetic acid, which contain the acid in an active ingredient content of 102 g / l. In addition to just listed application restrictions, you will also receive a few hazard statements and precautions when purchasing this product: "To avoid risks to humans and the environment, follow the instructions for use.", "Causes skin irritation.", "Causes serious eye irritation."; "Do not let the medium and / or its container into water."
In addition, several conditions of use and conditions, eg. B.:
  • SB001: Avoid any unnecessary contact with the remedy. Abuse can lead to health problems.
  • SB110: The guideline for the requirements for the personal protective equipment in the plant protection "Personal protective equipment when handling pesticides" of the Federal Office for Consumer Protection and Food Safety must be observed.
  • SE1201: Wear tight-fitting safety goggles during application / handling.
  • SF245-01: Re-enter treated areas / cultures only after the spray coating has dried.
  • SS1201: Universal protective gloves (plant protection) wear during application / handling.
  • SS2203: Protective suit against pesticide wear during application / handling.
  • SS703: Wear sturdy footwear (e.g., rubber boots) during application / handling.
If you mix yourself, even in the quantities provided by law (which is not so easy, because you first have to find out whether acetic acid is sold in the store in the same concentration in the sense of the Plant Protection Act), you are still using a plant protection product within the meaning of the law but a prohibited crop protection product. After all, your own mixture is not checked by the state, so that its use will result in a fine. If you use this vinegar anywhere outside of garden areas (or in the garden not sufficiently limited), so chances are that the vinegar lands on public ground or in the water, commit an environmental offense, § 324 StGB water pollution, § 324a StGB soil contamination Example, here is in doubt a prison sentence the result. With salt, in the form of our table salt sodium chloride (the sodium salt of hydrochloric acid) it looks exactly the same - our environmental criminal law has been created precisely to prevent people from using dangerous chemical substances like salt (or hydrochloric acid or arsenic or what do I know a poison) in the area. As a pesticide, salt (such as hydrochloric acid or arsenic or what I know for a poison) is not allowed at all. Obviously, it is better suited substances, the salt, which may be used in our environment, is used as road salt to make dangerous smooth roads for the citizen safely passable. Unless exceptions are expressly provided for by a decree of the municipality, this road salt may also be applied only by state organs and not by private individuals.
What vinegar and salt do with the garden
All these regulations do not exist from regulatory control mania, but to protect the citizen from irresponsible fellow citizens, with salt and vinegar with good reason: salt in the soil endangers the groundwater, changes pH and soil structure up to the compaction and sludge, and the plant life in the Environment may also be deprived of livelihood. Even road salt is now spread in the vast majority of areas of Germany only at very specific danger of ice. Because it is now known that it damages trees and shrubs massively (main problem: root damage), pollutes soil and groundwater, causes wounded paws in animals, attacks shoes, clothing and concrete. Both do not distinguish whether they are used against weeds or the favorite rose - and vinegar is not necessarily harmless, especially for the garden, because molds still grow at a pH of less than 2, so you could mushroom your whole garden with vinegar, Before you even think of spilling vinegar and salt in the garden, here are some thoughts and information about weeds in the garden:
The weed in the garden - is made by the gardener. And in two ways:
1. How much unplanned growth develops in a garden is up to the gardener.
A garden is a piece of nature in which plants develop. Plants are living things that want to reproduce like all living things. But the garden is a piece of nature designed by man, and this man, the gardener, also has it in his hands to what extent and extent the plants reproduce in his garden. In the truest sense of the word in hand, because traditional gardening is manual work, for example, foreign vegetation is as classic as effective for a very long time prevented by weeding from developing excessively or at all. If a little more brain work is added, information on the traditions of good professional practice of gardening craftsmanship (which our new Plant Protection Act of February 2012 in § 3 also prescribes for the implementation of pest control measures), resulting in centuries of experience, creates a naturally overgrown garden which is in ecological balance.
In which unwanted vegetation is hindered by natural resources in development:
  • By equipping the garden with robust plants that are sufficiently adapted to the location
  • That are competitive enough not to be disturbed by any seeds being flown in from somewhere
  • In which the garden soil is not weakened by repeated planting with monocultures
  • But is strengthened by maintaining a suitable crop rotation or sequence of decorative plants
  • And is maintained by application of compost, green manure, deep-rooted area planting
  • In which there are no naked and bare earth surfaces on which unplanned growth can develop unhindered
  • Because naked, open to weathering exposed earth is nowhere in nature (except in the desert)
  • On surfaces covered with ground cover or a layer of mulch, perhaps a single alien plant, but certainly no weed mass growth will develop
2. What "weeds" is, determine yourself.
A cabbage is an herb, simply a plant that does not lignify; The definition of the "un" herb is rather peculiar: a plant becomes a weed - a destructive plant that is often destroyed by spreading toxic substances on its growth site - by a human calling it a weed.
Vinegar and salt are not suitable for destroying weeds in the garden, and they are certainly not allowed. However, you are free to choose which plant is a weed for you - if you do not follow the definition of for-profit land exploiters, the weeds in the nature-led garden are reduced to almost zero with just a few tricks.
