Each owner of a summer cottage wants to make a green lawn in front of the house. For these purposes, use lawn grass. She always looks good and is easy to care for. But it so happens that the lawn begins to become covered with yellow spots and instantly loses its decorative effect. There are many reasons for this. In more detail about them - further.
Wrong lawn mowing
To make the lawn always look fresh and well-groomed, you need to cut it regularly. Before doing this, you need to understand how tall the grass should remain after mowing. It depends on the type of lawn being formed, but it is impossible to shorten the grass by more than a third of its height. Lower will be more difficult to restore the balance of nutrients, and it will begin to gradually die. It is also necessary to adhere to a certain haircut frequency - at least once every two weeks.
Important! You can not carry out a haircut in the midst of a hot day. Moisture begins to evaporate faster from the damaged plant, and it dries.
Lack of moisture
The lawn can suffer from both a shortage and an excess of moisture. This causes its color to turn yellow. Therefore, it is necessary to choose the optimal watering schedule. The characteristics of the soil, weather conditions, shading, and also the type of grass should be taken into account. To make it easier to care for the planting, it is advisable to choose drought-resistant herbs.
The lack of moisture will be indicated by the curl of the grass after being pressed.
Usually in the summer, watering is carried out twice a day, in the morning and evening. Water needs to be poured a lot, but so that puddles do not stand on the site, otherwise the underground part of the plant will begin to rot, and the aboveground will fade. Then you have to stop watering for a while, wait until the land is completely dry, and then resume irrigation procedures, following the schedule.
Fertilizer shortage
The uniformity of the color of the green lawn depends on the amount of fertilizer applied. For normal life, it is necessary to fertilize the soil 3-5 times during the growing season. Separately, it is necessary to carry out preparatory work for the winter.
Nutrient deficiency
Due to the constant mowing, the lawn grass needs a lot of nutrients that give it strength to recover. The growth of green mass provides nitrogen. Therefore, after each mowing, the element must be brought into the ground. If there is a lack of this element, yellow spots will appear. With the onset of autumn, it is necessary to switch to potash fertilizers.
Important! Water contributes to the deep penetration of nitrogen into the soil, so after each feeding, it is necessary to carry out irrigation procedures.
Mechanical damage
If a special grass intended for football lawns was not used to create a lawn, then after regular walking on it, holding picnics, yellow bald spots may appear. Pets can also spoil its appearance. Therefore, it is necessary either to plant special grass, or to limit the territory. Yellowed bald spots need to be cut as much as possible, nourished and watered abundantly.
Errors in the laying of the lawn
It is difficult to guess the density of grass sowing. If you leave a lot of free space between the seeds, there will be bald spots. With a dense landing, the root system will be too crowded. It will begin to weave, and the plant will lack in nutrients, moisture. If the yellowing of the lawn is associated precisely with a thickened planting, then you must try to thin out it and introduce more mineral elements into the soil.
Did you know? In California, due to regular droughts, there is a program to replace moisture-loving lawns with drought tolerant ones.
Winter freezing
In severe winters with little snow due to insufficient snow cushion, the root system may freeze and die. Naturally, such a plant begins to turn yellow. The root system may also die due to the formation of an ice crust on massive snowdrifts.
Such grass is not subject to restoration, therefore, from autumn, care must be taken to shelter the lawn so that the soil does not freeze strongly. To do this, you need agrofiber and spruce branches. Instead of spruce branches, you can use dry grass.
Pest damage
If uneven yellow spots begin to appear, then most likely pests have wound up on the site. More often it is larvae of the May beetle, wireworm or bear. They feed on plant roots. You need to deal with them with the help of biological products, such as Nemabakt. Against the bear, you can use high-frequency repellers and special traps.
Another reason for the appearance of yellow spots on the lawn may be ants. They also love to feast on the roots. Against them, you can use insecticides or plant spicy herbs nearby.
Disease
The lawn may also turn yellow due to illness. Most often due to powdery mildew and rust. For the development of these fungal ailments, certain conditions are necessary: increased air humidity and sharp temperature drops. Another reason why these diseases begin to develop may be a lack of nitrogen in the soil.
Did you know? In the XVIII century. in Europe, short-cut grass on the lawns was a symbol of luxury.
It is necessary to solve the problem by reducing the frequency of irrigation, by foliar feeding with urea along with fungicides, thoroughly cleaning vegetable litter and applying nitrogen-containing fertilizers.
Lawn grass, like any plant, requires attention and care. Without them, she quickly loses her attractive appearance and begins to turn yellow. To avoid this, follow the rules for lawn care, and then the problems described above are not scary for you.
