Planting a lawn is hard work.

The number of seeds of cereals is sown per sq. m.

Questions arise if the lawn turns yellow and dries in the first year after laying. In such a situation, the root of the problem lies in the wrong fit. The package with lawn grass indicates the frequency with which seeds should be sown per 1 sq. m. When these norms are violated, there is an excessive amount of grass and there is not enough sun for it, the access of food and air to the roots is limited and the growing process is disrupted. Due to the dense planting, cereal grasses rot, dead specimens are noticeable.

Due to the rare planting, weeds are quickly overgrown. Weeds clog grass mixtures of cereals, depriving them of light and nutrition. It is possible to avoid their invasion with proper, uniform seeding. When weeds appear, you need to remove it with the root, and plant a grass mixture in the resulting bald spots.

Some hosts in weed control use chemistry, which violates the environmental friendliness of the green coating.

To prevent the error called “incorrect seeding” from happening again, you must:

prepare the soil well by fertilizing it;
dig the ground and drain the bottom layer;
level the surface;
distribute the seeds evenly;
according to the instructions, calculate the seeding density.

With a thickened landing, it is impossible to save the lawn. Remove the top layer of turf and start laying it all over again. It is almost impossible to thin the grass by hand. There is a mechanical thinning method, but it is not cheap. Some summer residents replace their unsuccessful option with laying a purchased lawn.

Reasons why the lawn dries

Green lawn - a source of rest and peace

The grass on the lawn turns from emerald green to yellow and withered, dry leaves are noticeable: this is a distress signal that she sends to her master. You need to look for a problem due to which the lawn has deteriorated in appearance. At one time, a lot of effort and money was spent on its formation, so it’s a pity if it becomes unusable.

The lawn turns yellow in different ways:

changes color completely;
covered with yellowish spots;
red or yellow bald spots appear.

The reasons why lawn grass dries are quite diverse:

lack of water or excessive moisture;
nutrient deficiency;
cutting rules violations;
incorrect lawn laying technology;
mechanical damage caused by pests, animals or humans.

The lawn loses visual appeal for a variety of reasons.

"Man-made" lawn created by the owner suburban area, easier to recover.Another thing is roll options grown in comfortable conditions: it is much more difficult to revive them, and most often it is simply impossible.

There are other reasons, but the result is the same - the lawn is spoiled. It will take time to restore it, but the main thing is to correctly identify the “roots of the problem”, otherwise the “green lawn” will have to be rebuilt.

Violation of the rules of watering: lack or excess of moisture

Proper watering will return the lawn to its original appearance.

Consider the question of why yellowing appears on the lawn, starting with watering. Most often, it begins to dry due to lack of water. If such a grass is crushed, and it does not quickly recover, then turgor (cell elasticity) is lost, which causes a lack of moisture.

Lawn watering should be approached individually. The need for moisture depends on the type of soil, the location of the "green carpet" (low or high), grass varieties, climatic conditions, and the amount of rain. Therefore, the recommendations do not say how often to water dry grass and how much water is required. The organization of proper lawn watering is not only a matter of technology, but also a well-thought-out system.

The best option for a lawn is sprinkling in the morning and evening hours, when moisture evaporates less and soaks the soil well. Sprinkling will help to evenly wet the lower layer of the earth, but it should be done in a dosed manner. Untimely watering during rains or droughts does not contribute to recovery.

Waterlogging will also result in yellowed or brown grass. This is possible with uncontrolled watering, when puddles form on the lawn. The same phenomenon is observed if the green cover is located in a lowland, where groundwater is located close.

The emerald green of the lawn has a stunning effect, it emphasizes all the elements of the garden, sculptures, single-growing trees, red brick tiles on the garden path.

If the summer cottage is located far away and it is not possible to water it regularly, then you can use a drought-resistant grass mixture for planting the lawn, which can be purchased at the garden center.

A serious problem is the lack of batteries

Cereal grasses need additional nutrition, feeding them is vital

During the summer period in the country, the grass actively grows and endures 6-8 haircuts per season. Under natural conditions, all dead vegetation, leaves, twigs return to the soil and are processed into humus, so wild herbage does not need additional feeding. Under artificial conditions, the grass on the lawn needs nutrients, otherwise it may dry out.

What to do, how to feed if the lawn grass turns yellow? On sale there are special complex fertilizers for the lawn. Grasses need phosphorus, potash and nitrogen fertilizers. The amount of mineral supplements depends on the number of haircuts. During the season, it is desirable to feed the grass about 4-5 times.

From spring and throughout the summer, nitrogen is needed for the intensive growth of green mass, so the application of carbamide (urea) at the rate of 5-10 g per 1 sq. m. is useful for the lawn. In autumn, on the eve of wintering, it is necessary to make potassium. The rest of the time, use complex formulations for lawns. If the “green carpet” has turned yellow due to a lack of batteries, then a week after fertilizing it can be partially restored.

Urea - one of the preparations for feeding

Before top dressing, the lawn must be shed so as not to burn the roots during treatment. Distribute fertilizers evenly, otherwise bald spots will appear in places due to a lack of nutrients, the grass will grow unevenly.

The video below shows how to remove bald spots on the lawn with fertilizer.

Proper haircut - lawn decoration

Lawns should be mowed regularly to avoid damaging plants.

Some gardeners are at a loss and cannot understand why the lawn dries in places. It's all about the wrong haircut.

There is an optimal lawn mowing regime, which is desirable to observe:

grass cover should be cut at least 2 times a month;
use lawn mower with sharp knives;
do not cut shorter than 5 cm; aoli
after the procedure, comb the grass with a rake.

Some careless owners let the grass grow, trimming it once a month. Untimely mowing of the lawn is a serious test and stress for plants, because they lose most of the stem. The grass suffers if this happens during the hot time of the day: with the loss of green mass, water evaporates actively and the herbage turns yellow.

A blunt tool is traumatic for cereal grass, as it twists some specimens with a root. It happens that the turf deteriorates and the lawn thins. With such mowing, there is more harm than good.

Mechanical damage on lawn grass

With active use of the lawn, it quickly loses its appearance.

Sometimes it seems that the lawn grass turns yellow for no reason. And they water it, and feed it, and mow it according to the rules, and the appearance of the grass is dull. The reason is banal - trampling by people. They sunbathe on the lawns, boldly walk or run on them, have picnics. A lawn is created for these purposes, but with a strong mechanical impact, the grass dies, acquiring an unpleasant yellow color and empty bald spots.

It can not do without the influence of animals and insects, so the protection of lawn grass from insect pests also applies to care measures. For example, moles building their underground passages violate the root system and spoil a flat surface. They are joined by shrews and bears, which eat up the roots of cereals. The fight against them is carried out with the help of low-frequency repellers or traps.

Pets: cats and dogs not only run on the grass, but also leave excrement in secluded corners of the lawn, which leads to the death and drying of plants. It is advisable to quickly shed the grass with water in this area. There is a defeat of lawn grass by birds. They feed on grains of grass mixture, pecking out young grass.

Red sod ants complete the picture. Having chosen the lawn as their second home, they lay passages and build anthills. They are repelled by a decoction of herbs or "heavy artillery" in the form of insecticides. But it is better to do without chemicals, because then people rest on the treated grass.

Grass on the trunk lawn looks just fine

Decorative, meadow lawns are not intended for games and picnics. And if the rest of the whole family is planned on the "green carpet", then it is better to use it for planting grass for a sports lawn. They include ryegrass, bluegrass, fescue, which are sown on tennis courts and football fields. They are resistant to trampling.

Why the lawn turns yellow: other reasons

Mechanical thinning and lawn aeration option

It is possible that the lawn has changed its color due to the following circumstances:

The grass was “attacked” by diseases in the form of powdery mildew or brown rust. The appearance of rust and powdery mildew on the lawn is associated with heavy rains, temperature changes, and a lack of nitrogen. Diseases are fought with fungicides, removing diseased grass a few days after treatment.
The grass has been frozen over in winter. If after the snow melts the grass is yellow, then the frosty weather “worked” on it. Usually this problem is typical for young grass, when the lawn is newly established. It is covered with snow, and in the spring the ice crust is broken so that the roots can breathe air. In winter, you do not need to walk around the area where the young grass is located.
Spilled chemicals. This contributes to the formation of a yellow spot, which indicates the complete death of plants. You need to clean the surface, change the soil and plant the seeds again. Avoid any chemical manipulations on the lawn
Insufficient lawn aeration. When the grass has been growing for years and its roots are closely intertwined, the problem of lack of oxygen arises. Solving it is easy. You need to take a rake and make punctures to the full depth over the entire surface. This preventive procedure is carried out twice a year.
Sometimes a “felt plug” accumulates on the lawn. These are the remains of mowed grass that were not removed in time. They cover the top layer with a dense carpet, blocking the access of oxygen to the roots. Wet soil leads to wetting and decay, lawn grass turns yellow at the roots. It is necessary not only to mow the grass, but to carefully and accurately remove debris and grass hay

Creating the perfect lawn is not a mystery with seven seals, but the work of hands and technology

Creating the perfect lawn is not a secret with seven seals, but the work of hands and technology

In order not to wonder: what to do if the lawn grass dries, during the summer three basic steps should be performed. This is aerating or puncturing the soil on the lawn with pitchforks or other devices. The use of scarification, which refers to the regular cleaning of vegetation with partial removal of sod. Mulching is recommended in autumn or during particularly hot weather to help retain moisture in the soil.

Emerald, resilient, juicy lawn is a joy for the family and the pride of the owner. This is exactly what he will be if he takes care of his “green offspring” in a timely manner, without waiting for problems to arise. Maintenance is not that difficult, so maintaining your green recreation area is a very real thing.
