Untimely lawn mowing
It makes a difference for a plant how much height it loses when mowing.

During the period of active growth of green mass, the lawn should be mowed up to 2 times a week. In this case, the procedure is carried out in the evening or morning, avoiding the action of sunlight.
Insufficient aeration of the lawn
The term "aeration" means providing the roots of plants with the amount of air necessary for normal life. Over time, the lawn sod becomes compacted to such a state that it does not allow air to penetrate the plant roots. Special devices that pierce the ground help to overcome the problem. The simplest option is shoes with long pins in the sole.

Lack of moisture
There are no general recommendations regarding the frequency and intensity of lawn watering for all lovers of beautiful lawns. Because in each case it depends on individual factors, such as soil composition, climate and weather, shade, types of herbs included in the mixture.
To protect yourself from yellowing of the lawn grass due to insufficient irrigation, you can choose a composition of drought-resistant herbs for sowing. These are reed and red fescues, bluegrass meadow ryegrass.
A visual sign of the need to water the lawn plants is their flatness after being pressed. If there is enough moisture, the green mass quickly straightens out.
Frequent mechanical stress
Yellowing and wilting of the lawn can be caused by people and animals that often walk on the lawn and trample it. This reason can be attributed to bumps of soil on the surface - a product of the life of moles. Small rodents are harassed with traps and ultrasonic repellents.

And at the same time, it does not enrich the soil with humus, like a wild meadow, where dead parts naturally return to the soil, fertilizing it. The soil must be fed with nutrients. A high nitrogen content is beneficial for the growth of green mass. The amount of dressing is related to the number of lawn mows. During the season of active growth, they can be made from 3 or more. With the arrival of autumn, plants begin to prepare for wintering and potash fertilizers should be preferred.
Yellowing due to illness

If the grass overgrows, a significant part of the length is cut during mowing, leaving the lower part of the stem without enough green mass in the ground part. The sight of such a lawn is not pleasing to the eye. Dense-stemmed and large-stemmed plants should be mowed at a level of 3-5 cm from the soil level.
