Weeds are considered plants

Weeds don't go away: Via weeds and pointer plants

"You have to put weeds in their place, otherwise the garden will run wild faster than you can say" weeding "". Such sentences are heard and read very often, and many gardeners seem to be eager to agree with this claim. However, we garden gnomes are passionate natural gardeners and are therefore of the conviction that there can be no UN herbs, because after all they are just as part of this nature as our cultivated plants. In the past, many of these weeds were used in the kitchen, dyeing, medicine and many other trades and crafts. The benefits of these plants have only been forgotten for a few decades and they are being labeled as weeds more than ever.

Weeds or weeds?

The main criterion for designating a plant as a weed is not clearly defined. In common parlance, however, a plant is considered a weed if it is undesirable in any way. If you view weeds as plants that you have not intentionally planted or sown, it certainly makes more sense to call them weeds.

Weeds protect the soil and support an ideal condition of the soil, the so-called soil tare. Through their rooting, they loosen the soil, ensure a chemical and biological balance and protect against erosion. The soil moisture is maintained by weeds and they are also extremely important for biological pest control.

Invasive neophytes: The "real" weeds

Due to the global exchange of goods and seeds, more and more plants from distant regions are coming to us. Some integrate, but many do not even tolerate our climate and do not spread. A few, such as. Ambrosia (ragweed), the giant hogweed or the glandular balsam can hardly be controlled and damage nature and sometimes health. In this country, invasive neophytes can actually be viewed as weeds that need to be avoided or controlled.

Soil determination by pointer plants

Some weeds have a very low tolerance with regard to their required living conditions such as. Climate, location, soil composition and soil quality, etc. As they provide good information about the soil composition and air pollutants, these types of plants are also known as indicator plants.

Pointer plants were only "rediscovered" and researched in the second half of the 20th century, primarily by the geobotanist Heinz Ellenberg. A detailed classification of various site parameters was determined by the pointer values ​​according to Ellenberg.
