Yellow spots on the lawnand dry patches of dying grass are a common sight on lawns. The reasons for this may be our neglect of lawn care, grass fungal diseases, as well as pests feeding in the ground on grass roots. Seewhy the grass turns yellow , where the yellow spots come from anddry patches on the lawnand how to prevent this from happening.

Yellow spots on the lawn - mistakes in care and fertilization

"

Yellow spots on the lawnand patches of drying grass may be the result of over-fertilization or uneven spreading of the fertilizer. The excess fertilizer burns the grass away, causing them to die. The solution in this case is to refrain from fertilizing for a few weeks and water the lawn abundantly. A large amount of water will help to dissolve the fertilizer and spread it deeper into the soil. "

Yellowing of the lawnmay also be the result of insufficient fertilization and lack of nutrients such as nitrogen.Nitrogen malnourished grass turns yellowand loses its green color. To restore the green color of the grass, you should apply a mineral fertilizer to the lawn, preferably rich in nitrogen and iron.

Yellow spots on the lawn - pests

Round patties of yellow, dry grasscan also be caused by dog ​​urine. While male dogs are famous for watering trees and shrubs, bitches take care of their needs on the lawn. Like the excess fertilizer described above, dog urine also burns grasses and causes them to die.These places should be watered abundantly, and also ensure that the dog does not settle down on the lawn anymore.

Yellow circular patches of dry grassare a characteristic symptom of grubs feeding. Larvae are beetle larvae that feed in the soil and damage the roots of grasses. Their presence can be confirmed by tearing off a fragment of the turf with a hand. If the grass is allowed to detach with the roots without resistance and we observe that the roots are underdeveloped or badly damaged, we can be sure that it is the work of the grubs. Often in the ground under the torn grass, you can see white larvae bent into a horseshoe. To observe them, however, you need to dig a little deeper, because they feed at a depth of 10-20 cm.

The grubs in the lawncan be treated biologically with Nemasys, which contains nematodes that feed on the grubs. Unfortunately, this preparation is quite expensive, and its use is not profitable, especially on small lawns (it is not possible to buy a small package). However, it must be admitted that this biological method of fighting grubs is very effective.
The P-Drakol preparation, containing microorganisms limiting the occurrence of both grubs and harmful soil nematodes, is much better in terms of price. This measure works in two ways, because on the one hand it eliminates grubs, and on the other hand - it supports the regeneration of grass roots damaged by these pests. As a result, it works quickly and effectively, and at a relatively low price, it is highly efficient. Now everyone can afford to fight grubs without chemicals, in a 100% natural way!

In an act of desperation, chemical pesticides against grubs, such as Dursban 480 EC, can be used. Currently, however, this measure should not be used in gardens (it is intended only for professional users, such as nurserymen or fruit growers).

Yellow spots on the lawn - fungal diseases of grasses

Yellow-gray patches on the lawn or a pinkish coating , usually occurring after spring thaws or in variable warm weather in summer, may indicate snow mold.Thorough raking of the lawn will help to remove the remaining dry stalks remaining after mowing, as well as the compact layer formed by them, the so-called felt. It is advisable to scarify and aerate the lawn. It is also necessary to spray against snow mold, as if left untreated it can lead to the death of the entire lawn. We can fight it with the natural and environmentally harmless preparation Polyversum WP.

Appearing in periods of hot and humid weatherround spots, bands or rings with a straw to brown colormay indicate grass rhizoctoniosis. Typically, the day before these spots appear, you can smell a specific smell above your lawn. To prevent this disease, you should not allow the felt layer to appear and rake the lawn regularly. In hot periods, water the lawn moderately in the morning, and in the evening keep the turf surface dry, reduce the doses or temporarily stop nitrogen fertilization.Spraying the aforementioned Polyversum WP preparation is also helpful in combating rhizoctoniosis of grasses.
In case of too low mowing, it is quite easy toyellow spot on lawnsThe symptoms of the disease are small spots, 1-2 cm in diameter, visible in the turf after mowing. The stains range in color from tanned to straw colored. They are usually clear, round, when combined, they give the effect of larger spots. Conditions favoring the appearance of yellow spot are: warm and dry summer, a large amount of dead leaves in the turf, poor plant growth, insufficient nitrogen fertilization.
Appearing squaresyellow-orange spots, where the grass can be easily torn off the ground, indicate that the lawn is infested with grass anthracnose. The occurrence of this disease is favored by high soil compactness caused by trampling, phosphorus and potassium deficiency, high content of dead leaves in the turf, as well as frequent sprinkling of the lawn surface without sufficiently deep soil moistening.The lawn should be loosened by aeration and scarification, the felt layer should be removed, the lawn should be watered less frequently but abundantly so that the water can penetrate the soil well, and also use a multi-component fertilizer.

Circular patches of dry grassforming rings (their center remains green), accompanied by the possibility of the grass being easily detached along with a weakened root system, may indicate gangrene of the blade base. The occurrence of this disease is favored by too low mowing of the lawn, light sandy soils and too high calcium content in the substrate. In this case, it is worth measuring the pH of the soil and if the result is above 7.0, apply acidifying fertilizers. The lawn should be aerated and adequate multi-component fertilization should be ensured.
As you can see, similar symptoms such asdry patches on your lawn and yellow spotscan have many different causes. Therefore, it is easy to make a mistake in identifying them, which makes it difficult to choose the correct method of treatment.If, apart from improving the growth conditions of grasses through proper care and fertilization of the lawn, we want to use spraying,it is worth choosing natural preparations, safe for the environment, such as the one mentioned in the article Polyversum WPIts operation is quite comprehensive, in addition, it stimulates the grass to grow. It can be used preventively even on he althy lawns, without the fear of damaging the turf.
