Do you dream of English grass, but have a colorful area in front of the door, which does not remotely resemble an English lawn? Some new gardeners then dream that this condition can be changed quickly and as desired with lawn weed-free and other lawn killers. Is that correct, or are other methods more appropriate?
Also for the lawn the requirement applies to integrated plant protection
Since our current Crop Protection Act came into force at the beginning of the year, home and allotment gardeners are obliged to observe the principles of integrated pest management: Before dealing with chemicals, the unacceptable condition must be tackled with gardening expertise and without the use of chemicals.
The first step is therefore the manual control of weeds, according to which optimal conditions should be created for the lawn, which prevents the reintroduction of the unwanted plants. If there are many weeds in the lawn, it may be because the soil does not have the quality that lawn plants like. If the soil on which the lawn grows has the wrong pH, this promotes the colonization of weeds that just love this pH. The grass plant then has not much to oppose to this settlement, it is weakened due to the unfavorable for them pH.
Factors of lawn care
In too acidic soil, many mosses like to love this low pH. If you still have many daisies in the lawn, you can actually be sure that the soil is too acidic. If you see a lot of chickweed or alfalfa in your lawn, it indicates that the soil is too alkaline. The next step would therefore be a pH test, the pH of your lawn should be around 6. A pH tester is available in any garden center or hardware store, if the soil is too acidic, you can apply lime to raise the pH. If the soil is too alkaline, which can be done by too much lime or by wrong fertilization, it must be acidified, there are various natural aids.
The fertilizer is the next factor that should be considered more closely. Turf plants need nutrients to grow, and so mixed nutrients that the needs of the grass plants are optimally met. There are many pointer plants that tell you which nutrients your soil lacks or which ones are too much:
- Stinging nettle, French herb or notification indicate adequate nitrogen supply,
- different types of clover, however, suggest nitrogen deficiency.
- So thistles, couch grass, dandelion and knotweed thrive particularly in condensed soil. Compacted soil favors lawnfelt, which must be loosened by scarifying.
- Or the pointer plants indicate waterlogging, such as field horsetail and field mint.
Saute the lawn
Keep in mind that Integrated Pest Management also means selecting the right plant for the given location. If you simply bought any lawn mix when you created your lawn, it is not always guaranteed that you really got the right grass plants (even if there was a nice name on the pack). The packaging labels are purely promotional names without compulsory character, the right grass mixture for your needs, you get if you choose the right seed mixture (RSM).
It may well be that the measures quickly strengthen your lawn to the point that in the future you can do without any turf weeds and lawn weed killers. But maybe your turf will want to be "stewed" for some time, with weed removal, scarifying, selective cutting, fertilizer and reseeding, all measures that are as natural to integrated crop protection as all the knowledge about gardening before the chemistry enters our gardens held.
Little room for turf weed free
Integrated pest management also uses pesticides when all other means have failed. But only then, and if one takes the integrated plant protection literally, there is actually no application space for Rasenunkrautfrei. Because it's about keeping the use of pesticides to a minimum to protect the health of all citizens.If a lawn is planted in the right place on the right soil with the right seed and is properly fertilized, watered and cared for in the future, you will get a nice lawn even without the use of turf weeds, so the use of pesticides is not really necessary to look at.
It may look different if your lawn does not suffer from weeds but pests. In accordance with the principles of integrated pest management, you are also obliged in this case to use all non-chemical methods of control first. These are hygienic, mechanical and plant-strengthening methods, and the targeted use of biological beneficials is conceivable. What has the long-term advantage that again more biological beneficials settle in your garden, which relieve you of work.
However, if you are attacked by pests that you can not control without pesticides, pesticides could be used. Whether grass weed free is the right remedy is more than questionable because you have a duty to use specific crop protection products, while Turf we know was designed to kill all plants except grass plants, according to the ideas underlying Integrated Pest Management, no conceivable procedure. That is why the legislature has currently withdrawn a large number of weed killers, the use of old stocks is prohibited under penalty of severe penalties.
Conclusion on the subject of pesticides
According to the new Plant Protection Act, only plant protection products that have been tested by the Federal Office of Consumer Protection and Food Safety and approved for use in household and small garden may be used in the house and allotments. At the same time, it certifies that, when properly applied, these products have no harmful effects on humans, animals and groundwater and, according to the latest scientific evidence, do not have an unacceptable impact on the natural balance. Such funds usually no longer have the toxic power to cause such considerable damage as the well-known Rasenunkrautvernichter, even from this point of view, it is now more promising to proceed with horticultural expertise against unwanted foreign growth or pests.
