Most lawns in Germany have a moss and weed problem - and in many cases that's simply because they are not properly cared for. If your lawn is to remain moss and weed-free in the long run, it is not enough to constantly reach for the scarifier or the iron rake and laboriously remove the unwanted plants. These grow as long as the grass growth is disturbed and the turf has enough gaps in which they can settle.
Fertilize grass regularly
Lack of nutrients is by far the most common cause of moss and weeds in the lawn. It quickly leads to gaps in the grass carpet and gives the unwanted plants room to grow. A nutrient deficit, however, you get with regular fertilizer very easily under control. In spring, preferably use an organic product such as Neudorff's "Azet Lawn Fertilizer". Research has shown that organic bound nutrients promote the so-called tillering of the grasses: these do not "shoot up" but grow wider with many new stalks and over time displace the competing weeds and the lawn moss. In addition, in late summer, you should use a potassium-rich so-called turf autumn fertilizer. It promotes the winter hardiness of the grasses and prevents frost damage and fungal infections such as snow mold.
With an organic lawn fertilizer such as Neudorff's "Azet Lawn Fertilizer", the turf becomes particularly dense
If you want a moss and weed-free lawn, you should also pay attention to the quality of the soil. Moose and many weeds have lower soil requirements than most turf grasses. They also grow on moist, compacted soils and are clearly superior to grasses under these conditions. Compacted soil, which is also very humid, must therefore be continuously improved if you want to get such turf problems permanently under control. As a rule of thumb: At least the top 10 to 15 inches of the floor should be well drained and loose. Remedy creates regular Besanden in the spring. To do this, first mow the lawn briefly and then spread a layer of sand one to two centimeters high. Now patience and perseverance is required: The procedure must be repeated annually. The first clear results occur after three to five years.
Annual sanding improves the lawn and keeps moss away
In addition to the Besanden has also proven the application of a so-called soil activator. It is a product of humus and microorganisms. It promotes soil life and the decomposition of organic residues such as the Morass, which in the course of the season in the turf deposit and can be felted. Particularly recommended are terra-preta-containing products such as the "Neudorff Terra Preta Soil Activator". The contained biochar forms particularly stable humus bodies and permanently improves the soil structure. It's best to bring about 100 to 150 grams per square meter of grass each spring.
The lawn moss has a high pH tolerance and grows equally well on acidic and alkaline soils, while turf grasses on acidic soils no longer thrive optimally. Regrettably, all lawns over the years tend to acidify: The decomposition of clippings on the sward creates humic acids that accumulate in the soil. In addition, every downpour washes out some lime from the topsoil. Sandy soils are especially acidic since, unlike loamy, they contain only few clay minerals and therefore do not have a particularly high buffering capacity. If you value a well-tended lawn without moss, you should always keep an eye on the pH, especially on sandy soils. You can easily find this yourself with test kits from the specialist retailer. The pH of sandy soils should not fall below 5, for clay soils below 6. If the pH on your lawn deviates from the stated values, you should apply carbonate of lime. It raises the pH again, improving the growth conditions of turf grasses.
With a pH test kit - Neudorff's "ph soil test" - it is easy to determine the pH of the soil beneath the lawn
Use good seed mixtures
For the new plant or the reseeding of the existing lawn after scarifying, buy only high-quality lawn seeds of well-known manufacturers. The frequently offered "Berliner Tiergarten" is not a brand product, but an unprotected product name, under which cheap forage grasses are often offered as lawn mixes.They grow very strong and form no dense sward. On the other hand, grasses that are specially cultivated for lawns are weak and grow very dense - they are a multiple of stalks per square meter compared to forage grasses. It pays to invest in quality lawn mixes as you will need to remove less moss. To rehabilitate a cheap lawn, you should first mow the old lawn very short and then scarify profound. After the seeds, apply a thin layer of lawn soil and roll the surface thoroughly. Finally, rinse thoroughly and keep the lawn constantly moist for about seven weeks.
The best lawn cut
Effortless, but true: Weekly mowing prevents moss growth. If you mow your lawn once a week during the entire period from March to November, during the growth period of the grasses, you will need to remove less moss. It is important that you mow a lawn that tends to Vermoosen not shorter than four inches - and that you always use a lawn sprinkler in summer dry periods.
Avoid light deficiency
The best way to grow a lawn in the full sun, because most turf grasses are very in need of light. In complete shade, such as under trees, a lawn mosses very heavily and has no chance of growing dense. The commercially available shade lawns also lead to a satisfactory result at best in partial shade. In dark corners, therefore, place better on shade-compatible groundcover. In semi-shade, the lawn to prevent moss, a little more elaborate care. In addition to the fertilizers mentioned, you should in no case mow the lawn too short and water consistently.
