If brown spots appear in the lawn, this is usually an indication of soil pests. Find out how to fight the lawn stains here.
Soil pests are usually to blame
Especially if such spots do not cover a large area, they are soil pests. Alternatively, excessive exposure to the sun could also be to blame. But then the spots would be larger or would occur more frequently. Especially if the lawn has a lot of weeds, is very dense and if it is also wet, then these spots can be caused by the meadow gnat. The animals lay their eggs in the lawn and the larvae then eat the roots of the grass.
Meadow cranes and cockchafers
The larvae can be clearly seen with the naked eye. So you can collect them very well, especially at dusk or when it rains. The eggs are laid in August and September, so it is best to keep the lawn particularly short and mow it more frequently during this time. In addition to the gnats, grubs can also be to blame for the spots. These may beetle larvae, which can be up to six centimeters in size, live just under the ground and also feed on the roots. Aerate the soil well and chop sufficiently.
