Recognize and combat lawn diseases

Lush green, dense and above all strong - that's what the perfect lawn looks like. The dream of every gardener. To succeed, of course, a good deal of care is necessary. Of course, the deciding factor is of course the choice of the right seeds. The experts of rasensamen.org recommend not only to pay attention to the quality of grass seeds, but also on the appropriate purpose.

Those who use poor quality risk later lawn diseases. Cheap seed is often already infected and makes diseases break out faster. But not only the grass seeds can cause illness, also wrong care or certain weather conditions influence individual illness pictures of the lawn.

In this article we would like to introduce you to the most important and most frequently occurring lawn diseases. At the same time, of course, you will also learn how these are treated.

Grass Diseases: The most important at a glance

Red thread

One of the most well-known lawn diseases is the redness. If the infestation is very strong, it may happen that the lawn completely dies. Normally, however, the lawn recovers fairly quickly.

Recognize:

You can see the redness of the pink to reddish needle-like fungus, which spreads to the top of the stalks. In the advanced stage, it can even happen that the stems stick together strongly through the fungus.

The initial stage, however, is characterized by a small brown spot in the lawn. The red threads form later.

Prevention and control:

The redness occurs when the soil is deficient in nitrogen, improperly poured, or not properly fertilized. Even very long-lasting moisture and high humidity can be the cause of the redness.

While you can not change much about the weather, you can pay a lot of attention to lawn care. To prevent the fungus, you should use a nitrogen and potassium lawn fertilizer (bestseller at Amazon.de). This compensates for the lack of nutrients. In addition, it is important that they aerate your lawn to give the soil a good permeability. Deciduous and Moravia should be completely removed, they ensure that the lawn does not get enough air and light.

"By the way: Short turf is more susceptible than longer turf. So do not mow too often or not too short.

Fairy rings

Another fungus-induced grasshopper disease is the witch's rings. These are divided into three different types, which differ only in the appearance optics. In all variants, the same control and prevention measures are carried out.

Recognize:

You can see all three types of a circular discoloration on the lawn. In most cases, mushrooms shoot out of the ground overnight - also in a circle.

Prevention and control:

Once the fungal infection has occurred, it is not so easy to remove it. It would be better, however, if the lawn disease does not even occur.

Since the cause of the fungus on the lawn is due to a nutrient-poor soil, it is first of all important that you perform a soil analysis. The gardeners at G├Ąrnerei P├Âschke show how this works on YouTube.com in a very descriptive video. Soil analysis will tell you what kind of soil you have and how it specifically stores the nutrients. This will ultimately tell you how often you need to feed a lawn fertilizer.

To prevent the witch rings, you must air your lawn with a scarifier. If you do not scarify regularly, you risk entanglement of the lawn and thus a nutrient uptake and thus the formation of witch rings is favored.

However, if the fungus is now to be fought, experts recommend watering the mushrooms with water and pouring in sand. Also, the cutting with a digger fork could help. You can not speak of a guarantee of success here. In the worst case you have to remove the earth up to 30 cm and make a ground exchange.

snow mold

Lawn diseases - recognize and combat snow mold


Snowy mildew occurs mainly in the cooler season, such as in spring and autumn. At about 10 degrees Celsius, it can develop magnificently. The snow mold is also a fungal disease of the lawn.

Recognize:

When the snow blows on the lawn small, dark brown or orange circular dots. These become larger with time and can spread further and further. Another important distinguishing feature is the wet grass, which can also be covered with a mucous film.

Prevention and control:

The snow mold survives only at temperatures up to 20 degrees Celsius. Then he dies. As long as you have to wait. Afterwards, you should take measures such as scarifying. The bald spots have to be resewed. Be sure to use high quality seeds to prevent new infestation.

Always keep in mind that lawns need a lot of light and air. On snowy surfaces the snow mold is much faster and easier than in bright and sunny locations.

Leaf spot

Blotch Disease is quite common on grass stalks but does not cause significant damage. Whether spring, summer, autumn or winter - the disease can occur at any time.

Recognize:

The leaf spot disease can be recognized in brown to black, often also olive green spots on the leaves. The size may vary, as well as the color. Hardly a grass variety is immune to this disease.

Prevention and control:

Particularly light "prey" are stressed plants and lawns, which are particularly dense and older. Scarify and aerate to ensure sufficient air circulation and, after mowing, always remove the clippings. This is the best way to prevent leaf blotch disease. Regular fertilizer administration can also help here.

root rot

Lawn diseases - recognize and combat root burn

Wurzelbrand is a grass disease that prefers new sowing. For lawns that are already well developed, rooting occurs less frequently. The main cause is overload - too much fertilizer, dryness, heavily compacted soil or turf. But it can also be due to the grass seeds, which were already infected before seeding.

Recognize:

To recognize the root burn is quite simple. The stalks hang limply down, the root collar is light brown colored (looks dried out) and often spots are visible on the lawn.

Prevention and control:

To prevent the disease, it is important to pay attention to high-quality seed. Prefer regular fertilizer feeds and ensure optimal soil permeability.

Infested plants can easily be pulled out of the ground. Kahle just seize.
