With the knowledge of the cause, the brown spots can be well corrected.

Brown spots due to lack of care

The most common reason for brown spots in the lawn is inadequate care. Dehydration can be behind the unsightly spots - the lawn can burn in direct sunlight and high temperatures. But also waterlogging can cause the stains. Remedy creates a regular scarification of the lawn, which loosens it, aerated and at the same time ensures that the rainwater can run well again. In addition, the lawn should be cut regularly, as too long blades of grass favor a brown color.

Browning by fungal attack

Fungi in the lawn are widespread and occur especially where the lawn is permanently wet. There are many different types of mushrooms, for brown spots in the lawn is mainly responsible for the redness. The name can cause confusion - the infested lawn shows no red, but straw yellow to brownish spots. The causes of redness are increased moisture in the lawn or stressful situations such as lack of nutrients, incorrect irrigation and extremely high temperatures.
The red tingling does not cause the turf to die - it just looks extremely unattractive. The brown coloration of the lawn usually disappears again when the moisture balance of the soil is right again. Should this fungal infection occur due to a lack of nutrients, then a good lawn fertilizer should be used.
The following methods effectively prevent fungal attack:
  • Lawn fertilizer: The lawn should be sufficiently supplied with nutrients.

  • Good ventilation: For a good ventilation of the lawn care should be taken to ensure that it grows healthy and beautiful.

  • Wind protection: Walls or dense hedges keep the wind off, thus promoting the spread of fungi; Also, in the fall, all the leaves should be collected from the lawn.

  • Water properly: Moisture favors the spread of fungi in the lawn. Preventive acts here a weekly, long irrigation. The water can penetrate deep into the soil while the lawn itself quickly dries up.

The meadow schnake can be to blame

Spring is here and the lawn shows brown spots? The grasshoppers may be at fault. These larvae populate the area just below the turf, eating up the roots of the individual grasses. In the period from August to September the female meadow snakes lay their eggs in the lawn, from which the larvae hatch after four to six weeks. These dig into the turf and usually begin in the fall, to do well on the grass roots.
In April and May, after hibernation, then begins the big feeding, in which the approximately four centimeters long larvae even feed on the leaves of turf grasses. The grass roots damaged by the larvae cause a partial yellow-brown color of the lawn before it finally dies. From a fungal disease, the infestation of meadow snakes to be distinguished from the fact that in this case, the individual grasses have no deposits or stains, but discolor uniformly.
Even a ground-breaking ceremony shows certainty: In the event of an infestation, numerous larvae of the meadow-snake show up directly beneath the soil surface. The control of the larvae can not be done by insecticides, since those in home gardens and allotments are not approved for the elimination of these pests.
Promising are other effective methods:
  • Kalkstickstoff: Per square meter of grass area, 30 to 40 grams of lime nitrogen can effectively combat the larvae. At the same time, the lawn is supplied with important nutrients. For this purpose, the calcium cyanamide should be already in early March, in wet weather, scattered.

  • scarifying: The grasshopper larvae always stay close to the surface. A low-set scarifier can thus reduce the population well. Subsequently, new lawn seeds should be brought into the soil, sprinkled with humus and then rolled.

  • SC nematodes: In the garden trade can

    Nematodes are ordered. These tiny little roundworms are set in water and distributed in the evening on the lawn. The SC nematodes invade the larvae of meadow snake and infect them with a bacterium. Within a few days, the larvae then die.
  • Collecting the larvae: With a mixture of 1 kg of moist wheat bran and 100 g of sugar, the pests are encouraged after dark to leave their underground passages - then they can then be easily collected.

Things to know about brown spots in the lawn - overview

  • Brown spots in the lawn indicate in the summer that the lawn has dried up.Regular blasting of the lawn in the evenings helps prevent this drying in hot phases.

  • The sun is then only low in the sky and can no longer cause burning of the blades of grass by means of the drops of water. If the brown spots remain despite irrigation, it may be because the soil does not absorb enough water. A wetting agent that helps to absorb water in the soil helps here.

  • The cause of these patches can also be a potassium deficiency. Here a needs-based and balanced fertilization is necessary so that the entire soil structure improves again. In fact, a well-fed and fertilized lawn is resistant to all types of diseases and is also resistant to stress caused by drought or frost.

  • Regular fertilization of the lawn should also be done regularly without brown spots or other damage.

Tips for pests in the lawn

If the lawn is attacked by pests, brown spots can also form. A pest is warbler larva. Whether this pest has attacked the lawn is also very easy to determine by the layman. You lift off a bit from the grass. As the grasshopper larva settles directly under the turf, it is very easy to recognize. Here it helps then in laborious detail work, the Gradnabe, which is attacked by the larva, to remove generously and re-sow the lawn afterwards.
If the brown spots in the lawn occur relatively quickly after a fertilizing process, there is the possibility that the lawn was burnt by the fertilizer. Fertilizers should always be used for fertilization, on the packaging of which it is expressly stated that the preparation does not burn the lawn.
In addition, the lawn should be blasted immediately after the fertilization process - after sunset - so that the fertilizer does not lie too long on the green area. If the lawn has turned brown after fertilizing, a salvage can be attempted by grass splashing. In the worst case, the lawn must be re-sown at the burned areas.
