Lawn grass is most susceptible to fungal diseases – various types of mold. The main signal of fungus is the presence of baldness and spots of different colours, white, grey, yellow, reddish-brown.

The main reasons for the development of mold are constantly overmoistened soil, lack of certain minerals or, conversely, its overabundance, the presence of vegetable felt on the lawn, prone to rot, as well as insufficient aeration or exhaustion of the soil.

In the case of mould, the lawn is treated with fungicides and regenerated by removing the turf layer and sowing new grasses. After that, it is important to eliminate the cause of the disease – to normalize the humidity, adjust the fertilizer complex or take drastic measures in particularly severe cases, for example, to remake the drainage system – a popular cause of excessive humidity.

Common fungal lawn diseases and their symptoms:

  • The so-called “red thread” is caused by the fungus Laeti-saria fuciformis, looks kike brown spots which then go pink. If you take a closer look, you can see the red threads of the fungus on the leaves. Reasons for this are high humidity or lack of fertiliser.
  • “Rusty mold” is caused by the Puccinia fungus, which forms round spots of rusty colour. The fungus dries the plant out and it dies. The disease is caused by soil exhaustion, sudden temperature changes, plant residues on the lawn and poor lighting.
  • Dollar spot disease affects parterre lawns due to a lack of nutrients, too frequent mowing and too much of a felt, and is characterized by brown and white spots  with the size of a silver dollar.
  • Fusariasis (fungus Microdochium nivale), a common “snow mold”, most often appears in spring in the form of yellowish dry spots, which grow and are covered with white fluffy mold in wet weather. You can stimulate the development of fusariasis if you do not pay attention to aeration and felt removal.
  • Ofiobiosis (fungus Gaeumannomyces graminis) affects the whole plant, its stems and roots, causing the grass to dry out and die. It is caused by disturbed gas exchange and increased soil ph levels in the form of dark green and then brown spots.

Algae, mosses and lichens.

Lawn diseases as mosses, lichens or algae may appear on areas with heavy clay soils in rainy, cloudy summers. Water stagnation on the lawn, untimely removal of plant felts, poor aeration and too little mowing also create a favourable environment for the growth of these plants.

Alternatively, your favourite lawn spots can be replaced with paving stones.

In order to avoid sunburn, the correct watering regime should be followed, avoiding daytime irrigation, and the composition of the grass mixture can be adjusted towards more sun-resistant varieties.

In most cases, lawn diseases and other problems that require emergency repairs are caused by improper or insufficient care.
