Drying and yellowing of the grass on the lawn is a distress signal that requires an immediate response. The reasons for this process can be many, and some of them are not so easy to eliminate. In the article we will tell you what to do if the lawn turns yellow and how to save it from death.
3 lawn care mistakes that cause yellowing
Most often, the lawn begins to turn yellow due to the fault of the owner himself. There are three main errors that cause this problem.
Mistake # 1. Insufficient watering of the lawn.
Irregular irrigation, especially in summer, is the most common cause of yellowing in grass.
Mistake # 2. Insufficient lawn fertilization.
Lawn grass needs the same nutrients as any garden or horticultural crop. Neglect of top dressing leads to the gradual withering away of the grass stand.
Mistake number 3. Incorrect lawn mowing.
Lawns very often turn yellow after a haircut. Mowing flaws leading to the death of the lawn will be discussed in detail below.
Other causes of yellowing of the lawn
Rebuilding a damaged lawn takes a lot of time and effort.Yellowing of grass can also occur for other reasons:
- Violation of the seeding rate when laying the lawn. The root system of too densely sown grass intertwines, the suction function of the roots suffers, and there is a lack of nutrition and moisture.
- Trampling. If the lawn is frequently walked on, the soil gradually compresses. With insufficient aeration of the root system, normal supply of plants with water and nutrients is impossible.
- Waterlogging. If the lawn is located in an area with a high groundwater table, or in a lowland with regular stagnation of rain and melt water, the root system of the grass can rot and the lawn turns yellow.
- Fungal infections. Yellowing of the lawn can cause damage by powdery mildew, fusarium, leaf rust, ophiobolus and red filamentousness.
- Mechanical damage to grass by insects, moles and other animals. Injury to the root system or the ground part of the plants provokes wilting and yellowing of the lawn.
- Freezing or damping of lawn grass in winter. This problem becomes apparent in the spring, after the snow melts. More often it occurs where the lawn is not properly prepared for winter.
Unfortunately, it is not always possible to quickly diagnose the cause of the yellowing of the lawn and eliminate it. Therefore, it is better to immediately make sure that this does not happen.
Selecting a yellowing-resistant mixture
Many problems with yellowing of the lawn can be avoided even at the stage of its laying - when choosing a grass mixture. Many modern lawn mixtures are formulated with the expectation of adverse conditions and are able to hide some of the flaws of care.
Since the main and most common cause of yellowing of the lawn is insufficient irrigation, it is better to immediately sow it with drought-resistant grasses. These include red fescue, reed fescue, ryegrass and meadow bluegrass. You can pay attention to the following ready-made mixtures:
| Name | Manufacturer | Composition |
| "Summer resident" | "MosAgroGroup" |
|
| "Blooming Life Drought-resistant lawn" | "Blooming Life" |
|
| "Canada Super Green" | "Seeds of Altai" |
|
The most convenient to use, of course, are sprinklers. There are several varieties of them:
| Sprinkler type | Advantages | disadvantages |
| Retractable fan-shaped | invisible, does not interfere with walking on the lawn when not working; allows you to irrigate difficult landscapes. | one rod covers a small area; does not allow regulation of the irrigation sector; time-consuming installation of the system. |
| Retractable rotary | does not interfere with walking when not working; the head rotates, allowing you to adjust the irrigation sector and the spraying distance. | time-consuming installation of the system. |
| Fixed oscillating | allows you to irrigate square and rectangular lawns without flooding paths and garden structures; can be mounted on a portable tripod; spraying distance up to 20 m. | not found. |
| Non-retractable impulse | spraying range up to 20 m; the ability to regulate the range and sector of irrigation; ease of installation. | not found. |
| Fixed circular | ease of installation; the ability to regulate the irrigation range by changing the water pressure. | sometimes the nozzles are clogged; does not allow regulation of the irrigation sector. |
The general advantage of sprinklers over hose irrigation is that the water does not break the soil or crush the grass. The disadvantage is the inconvenience of irrigation in windy weather - small drops of water scatter, not reaching the goal.
Organization of the correct mowing of the lawn
The underground drip irrigation system is convenient, but its installation is associated with high labor costs and financial investments. Mowing your lawn right takes experience and thoughtful thinking. The death of grass after an inept shearing is caused by several reasons:
- Mowing too rare. There is a difference - cut the grass by 1-2 cm or half the length at once. In the second case, the plants are under severe stress and dry out instantly. In the summer, when the grass grows actively, it is necessary to mow the lawn 1-2 times a week. Read also the article: → "".
- Cutting too low. The practice of "shaving" the grass to a height of less than 3 cm leads to rapid burnout of the lawn and the formation of bald spots. Different mowing heights are recommended for different types of lawn, which must be strictly observed. In dry years, it is permissible even to exceed it by 1-2 cm in order to protect the grass stand from drying out.
- Sloppy mowing. If you mow the grass with blunt knives or mow a wet lawn, the grass does not cut, but tears - sometimes even by the root. Such damage to the turf can lead to yellowing and drying out of areas of the lawn.
A good lawn mower helps to organize the correct mowing, allowing you to adjust the cutting height. It is more difficult to do this with a trimmer or brushcutter. Feedback monitoring has shown that it makes sense to pay attention to the following models of lawn mowers:
| Name | Advantages | disadvantages |
| Husqvarna 54 NovoCut | lightweight, quiet, safe; cutting blades made of quality materials; has a removable grass catcher. | high price. |
| "Makita ELM4612" | powerful; knives of high quality, keep sharpening well. | the distance between the wheels is wider than the mowing area. |
| "Bosch Rotak 43 LI" | lightweight, maneuverable, safe; spare battery included; the batteries charge quickly. | high price; small collection box. |
Tip # 1. If the grass on the lawn has grown too much for some reason, it is better to mow it in two steps with an interval of 4-5 days. This will reduce the risk of the grass drying out quickly after cutting.
Organization of competent feeding of the lawn
Do not mow your lawn in the sun. It is necessary to plan the procedure for the evening. Usually, when laying a lawn, the soil is filled with fertilizers. However, this is not enough for a long time, because the lawn is not a wild meadow, where organic matter naturally returns to the soil and enriches it with humus. Moreover, the grass is an intensive cultivation culture. She is constantly decimated, and she needs a significant amount of nutrients to recover. Therefore, the question of feeding the lawn is relevant for a caring owner.
Fertilizing your lawn is not a difficult task if you have regular watering. There are a lot of special mineral complexes that can be applied with irrigation water. Also on sale there are many dressings that are simply scattered over the lawn, and then watering is done:
- Fertika Lawn Spring-Summer. A granular complex that scatters over the lawn in early spring, immediately after the snow melts. Top dressing is repeated 3-5 times during the period of active grass growth. .
- « BonaForte lawn spring-summer ". Powder complex with zeolites, suitable for any type of lawn. Spreads over the site before watering.
- « BonaForte for lawns ". Liquid concentrate applied with irrigation water from spring to early September, once every 2 weeks. Easy to use and economical.
- "Fasco Organic-mineral fertilizer for lawns". Contains a full range of macro- and microelements and 20% organic matter. Environmentally friendly, dust free, easy to use, chlorine free.
Protection of lawn grass from insect pests
Unfortunately, a plentifully fertilized and watered lawn attracts not only people, but also pests. Among them, the most unpleasant are bears, wireworms and beetle larvae. If pests of the terrestrial part of plants on a mown lawn are almost never found, then underground inhabitants willingly settle in well-groomed soil.
Tip # 2. The higher the frequency of a sound, the worse it propagates in a dense environment. For this reason, ultrasonic scarers do not work on the bear.
Prevention of yellowing of the lawn: aeration, scarification and mulching
Soil dwellers damage the root system of plants and cause damage to the lawn. To prevent yellowing of the grass, the lawn needs not only to be fertilized and watered, but also to carry out a number of the following activities:
- Aeration. The turf on the lawn becomes too dense over time, preventing air from penetrating to the roots. Trampling the lawn while walking on it contributes to the same. The soil can be aerated using special devices that pierce the soil. The simplest is boots with long pins on the sole.
- Scarification. The essence of the procedure is loosening and cleaning from mechanical debris. Light scarification is carried out by combing the lawn with a rake. Deeper with a turf rake.
- Mulching. This manipulation is capable of replacing top dressing of the lawn, and in addition, contributes to the long-term preservation of soil moisture. It is convenient to mulch lawns with a shallow grass cut formed when mowing with lawn mowers with mulching function.
Regularly carrying out these procedures, in conjunction with the correct irrigation, fertilizing and mowing regime, is guaranteed to keep the lawn grass fresh and healthy.
Topical issues of resuscitation of a yellowed lawn
The root system of fescue, bluegrass and ryegrass penetrates to great depths and is not afraid of drought. Question number 1. Why does the lawn turn yellow with spots and what to do about it?
The yellowing of the lawn not over the entire area, but with spots, has five reasons: trampling, burning with unevenly distributed fertilizers, burning with animal excrement, ophibolus fungus infection and toxic soil excretion. If there are no well-groomed paths on the lawn, and fertilizers are applied correctly, you need to observe whether any animal has chosen the lawn as a toilet.
Most often, the ubiquitous cats spoil the lawn. Kema Clean Garden helps to discourage animals. It is environmentally friendly and is a finely ground volcanic rock with essential oils that repel cats and dogs. It is enough to scatter it on the lawn grass. It lasts a long time, the oils are not washed out by the rain soon.
If the problem is not with animals, you will have to remove the turf in the place of constant yellowing and check if there is any buried debris under the soil. It often poisons the soil, causing local yellowing of the grass.
Question number 2. How to deal with red thread on the lawn?
First of all, it is necessary, if possible, to normalize the humidity - to arrange a good drainage of the lawn and normalize watering. The next step is to treat the grass with fungicides, for example means "Coronet" or Bordeaux liquid... For prevention, it is necessary to regularly aerate the lawn.
Question number 3. Is it possible to save a frozen lawn in winter?
If the lawn is badly affected by frost, it is easier to reseed it. In case of minor lesions, it is necessary to clean it well with a rake, fertilize and water. Do not trample the affected lawn until summer, and the grass will recover.
Question number 4. Can the increased acidity of the soil provoke a yellowing of the lawn?
Undoubtedly. The optimum soil pH for most lawn grasses is neutral. A shift in acidity up or down can cause chlorosis. Especially harmful is not even acidified, but overly alkaline soil. It is easier to cope with increased acidity - it is enough to deoxidize with chalk or dolomite flour. Fluff lime is not used on lawns.
Every owner of a lawn surface has at least once encountered such a problem as yellowing of the grass. The grass on the lawn turns yellow for many reasons - improper care, lack of nutrients. Some immediately go to the store and buy expensive fertilizers, which can only aggravate the situation. This is due to the fact that many owners of summer cottages are not even aware of why their lawn turns yellow.
There are several main reasons for the yellowing of the grass on the lawn:
- Improper and irregular watering;
- Lack of feeding;
- Diseases;
- Trampling;
- Items left or forgotten for a long time;
- The influence of certain animals;
- Incorrect grass cut.
As you can see from the list, the most common cause is improper care. What to do if the lawn turns yellow? Take good care of him! Each package of seeds has an instruction, which includes a "care" item. If, for some reason, the instructions were not found, then here are simple rules that will help not to harm the grass cover, but to improve the appearance of the lawn:
- Water your lawn at least once a week. This also applies to drought-resistant lawns. Decorative need to be watered every 3-5 days.
- Don't forget to fertilize. The best feeding schedule is 2 times a month.
- Don't neglect your haircut. It is advisable to mow the lawn at least once every 7-10 days.
By following these simple rules, you will forget that the grass turns yellow on your lawn.
Found more and more grass growing on your lawn? Before taking any action, it is worth finding out why the lawn turns yellow.
Try to remember how often you looked after him and fed him with special fertilizers. If there is insufficient moisture or a lack of fertilizer, then it's time to take emergency measures before the lawn turns into a dried yellow field.
Provide good watering if time permits. It is best to do this for two days in a row. You need to water in the evenings - abundantly, but without turning the lawn into a swamp. If there is little time to restore the lawn, then the lawn is properly shed with water, even the formation of shallow puddles is permissible.
Simultaneously with watering, you can apply a complex of fertilizers. To do this, dry universal fertilizers for the lawn are scattered in an even layer before watering, and then they arrange the lawn "water procedures".
If the lawn turns yellow not from poor maintenance, what to do? You regularly looked after the grass carpet, but suddenly something went wrong, and the lawn began to turn yellow. There may be several reasons for this.
- The first and most common is disease. Examine the grass around the yellowed area. Are there any uncharacteristic spots or traces of insects on it? If you find any of these, it is worth applying special fertilizers or insecticides.
- Are there animals in the house? Look closely at the lesions of the grass cover. The grass on the lawn turns yellow in large patches or closely spaced spots. If the yellowing is of a "point" nature, then, most likely, it was not without your pets or small rodents living on the site.
- Sometimes it happens that over-caring for the lawn leads to the yellowness of the grass. The lawn turns yellow - what to do? Our answer is to apply less fertilizer!
The lawn turns yellow after mowing
Mowing is one of the most important steps in green lawn maintenance. Does the lawn turn yellow after mowing? So this is the problem! How and with what the grass is mowed plays a big role in the attractiveness of the lawn.
Often, the grass is mowed with special trimmers or massive lawn mowers with knives. The sharpness of the knives also determines how well-groomed the lawn will be. Keep track of this and change the knives in time - and then your lawn will not turn yellow after mowing.
When using the mower trimmer, make sure that the cut grass does not get caught in the rotating mechanism. The slower the motor spins, the weaker and dumber the knife-line.
The lawn turns yellow with spots
It is not uncommon for the lawn to turn yellow with spots. What are the reasons for this phenomenon?
- Rodent activity;
- Abundant watering;
- Forgotten things;
- Spilled chemicals.
If the lawn turns yellow in small spots located far from each other, then most likely rodents have started under the grass cover, which eat up the horses of the plants, thereby leading to the formation of yellow spots.
Also, dampness and abundant watering can provoke the yellowness of the grasses (especially in shady areas). Balance watering and you will get rid of yellow spots.
Lawns at summer cottages are most often used as a living carpet. Therefore, planting chemicals or building on the lawn is a common thing. All these factors can significantly damage the surface, so it is better to carry out “dangerous” measures for the lawn aside.
Is the grass on the lawn turning yellow? Don't panic! Understand the reasons and take action!

Depending on the varietal group, the age of seedlings suitable for planting in open ground is: for early tomatoes - 45-50 days, average ripening times - 55-60 and later dates - at least 70 days. When planting tomato seedlings at a younger age, the period of its adaptation to new conditions is significantly lengthened. But success in obtaining a high-quality crop of tomatoes also depends on the careful implementation of the basic rules for planting seedlings in open ground.
Why does the lawn turn yellow- in any season, due to various factors, in different areas?
There can be several reasons for this at once - from improper care to diseases. Therefore, first of all, it is necessary to find out why the lawn grass turns yellow - and only then to begin to correct the situation. On the pages of the site you can find several useful tips that will help you in caring for the site.
Expanded up-to-date information will help identify the causes of diseases, choose the optimal plant variety, and also learn about other ways to decorate the site.
Why the lawn turns yellow - possible reasons
So, let's consider the most likely causes of yellow spots on the lawn in most cases:
Insufficient watering. In the summer heat, the grass cover must be irrigated regularly, and this must be done at strictly allotted hours so as not to harm the plants. You can install several sprinklers if the area of the site is large, or you can regularly move one sprinkler to a new place, breaking the lawn into several squares. You need to water the plants in the morning or in the evening, otherwise the water drops will turn into small lenses, and the grass will begin to turn yellow even more.
Irregular yellowish or reddish spots scattered over the site may well belong to unwanted guests - cats and dogs. If so, it is recommended to install ultrasonic repellents and wait for the plants to recover.

Another reason why the lawn turns yellow may be a lack or excess of nutrients - nitrogen and iron. It will be necessary to feed the plants with nitrogen fertilizers - urea, ammonium nitrate, ammonium sulfate, iron sulfate in the recommended doses. For prevention, top dressing should be carried out 3-4 times per season.
Red filamentousness. Usually it appears in autumn - spots of irregular shape acquire a yellowish color, then straw - as if fading in the sun. At high humidity, patches of pinkish mycelium are also visible.
The reason is the lack of nitrogen, frequent fogs and prolonged dampness. Often too low pruning of grass and the appearance of various pests can also cause yellowing. When pruning, it is necessary to set the technique to an average level - this will allow you to achieve the required cutting height of the grass cover.
To avoid even the possibility of yellowness, it is recommended to carry out regular mowing of the grass, feeding and watering, as well as to take care of the absence of shade and to drain the soil well. The main task is to find out why the lawn grass turns yellow - then you can take measures to save it.
Conclusion: After studying the article, you can answer the question: What are the causes of yellow spots on the lawn. How to fix?

The forests near Moscow are sick. Spruce on private plots also suffers. Brown bald patches from dead trees grow catastrophically quickly in size. This can be seen especially well from the plane. The situation is also bad with deciduous tree species.
Bark beetle
The bark beetle is destroying the forests near Moscow before our very eyes. This small bug manages to cope with huge trees. The insect turned out to be not as simple as it seems. Bark beetles (from the order of coleoptera) resemble weevils without an elongated tube on their head. They have the necessary set of special "tools" with them. For example, indentations with teeth on the elytra. The bark beetle larvae are thick and legless. They are white in color with a large brown head. Bark beetles are family insects. During the breeding season, some species form monogamous families (male and female), others - supporters of polygamy (male and several females). In a monogamous family, a female equips the dwelling. She herself gnaws a course and waits for the arrival of the male. In a polygamous family, the male has to work hard, gnawing out a spacious mating chamber. After mating, he loses interest in "building". Now the females make their own uterine passages. Among the bark beetles there are many "idlers" who are too lazy to build uterine passages themselves. They use empty tunnels of other bark beetles to lay eggs.
Beetles, first of all, are attracted by weakened (for one reason or another) trees. Females have an excellent sense of smell, acting at a distance of 500 - 1000 m. Males sense smells weaker. The sense of smell helps insects to select the appropriate wood species of a certain condition. In the life of bark beetles, their own tragedies happen. The worst is for pioneers, who often die from the resin or sap of viable trees. Most of the beetles move to the trunk only when they catch the smell of the dust thrown out. They pounce on a weakened tree and populate it. The nature of the activity of different types of bark beetles (choice of wood species, system of moves, etc.) is so individual that experts are able to classify the pest bark beetle "by handwriting".
Spruce bark beetle (bark beetle-typographer)
The spruce bark beetle (typographer bark beetle) infects conifers. This insect rarely attacks pine and fir. The black-brown beetle (body up to 5.5 mm in length) wakes up after hibernation in late April - early May (in the North - late May - early June) and begins to fly and crawl in search of a suitable spruce. This species devastates vast areas of forests in Western and Eastern Europe. In Asia, it is common in Siberia, the Far East, Sakhalin and Kamchatka. The beetle chooses a tree and attacks it. First of all, the male prepares the breeding chamber. Females are included in the work later, they are responsible for the lateral uterine passages. The branches contain larval passages for pupae. The growing larvae gnaw through the lateral passages in the bast (soft tissue under the bark). A branched "bark beetle nest" appears. If it is destroyed, then the larvae die very quickly. The bark beetle-typographer flies out not only in the spring (mass flight), but also in the summer (in smaller numbers). Most of the beetles hibernate in warm leaf litter, therefore, even in frosty winters, only a small part of the bark beetle freezes out. Those bugs that remained for the winter on the trunk under the bark of the tree usually die.
Mass death of spruce trees
What kind of ate does the bast beetle strike? First of all, weakened ones. Strong and young - less often. A healthy tree, attacked by a bark beetle, soon dies, as there is a total disruption of the flow of water and nutrition from the roots to the crown due to damage to wood and bast. Inhabits the bast beetle and trees left after felling. It can even be found on stumps and in wood. The mass activity of the bark beetle-typographer, which rages in the spruce forests, is associated with many factors. This is an increase in air temperature, drought, felling, dense spruce forests, solid spruce plantings, etc. They perish from him and eat in private plots. There is a high probability of introducing an insect when planting large trees. The spruce tree inhabited by the bark beetle, but not yet dead, can be easily seen by indirect signs. For example, a woodpecker willingly hollows the trunk. The bark beetle also attracts the nuthatch. Tiny round holes in the bark indicate that some of the beetles managed to fly out. Small sawdust on the bark and at the foot, wood "flour" indicate a tree that is actively assimilated by bark beetles. Often, brown needles (on spruces and firs) are also a sign of the presence of typographer beetles. The most unfavorable prognosis for a tree is the bark peeled off or fallen from the tree, small brown sawdust on the bare trunk.
The bark beetle-typographer destroys the forests near Moscow. Especially in Dmitrovsky and Istra districts. Weakened trees can die very quickly, in just a couple of weeks. Huge age-old fir trees last longer, but they are difficult to resist the typographer. During the dry season, most of the spruce forest is at risk. In 2012, the bark beetle is incredibly active. To stop the outbreak of the population, rains and a decrease in air temperature will be able to. In cool (below + 17 ° С) wet weather, this insect is inactive.
What to do?
Ecologists attach great importance to improving the sanitary condition of the forest. They do not consider chemical treatment to be a solution. There has been a lot of talk lately about pheromone traps that should attract beetles. In the Moscow region, such traps are placed in forests at the end of April. The attitude of specialists towards them is ambiguous. Worst of all, the beetles attracted by the scent simultaneously populate the spruce, which are on the approach to the trap. Sometimes it is advised to remember about immunomodulators (help trees) and insecticides (to kill the bark beetle). In the spring, you can cultivate the land under the spruce with insecticides. Attempting to poison a beetle hiding under the bark is a pointless exercise. Systemic drugs (Aktara, Aktellik, etc.) are also not always effective. They shed the ground under the spruces in the spring, and later spray the trunk and part of the crown. It was noticed that in mixed plantings (with deciduous trees) there is less spruce beetle.
Not only forest spruces perish from the bark beetle-typographer. The city also gets it. Trees in private plots also suffer. Perhaps, in these cases, it is worth seeking help from a qualified dendrologist. Or plant (just in case) new young Christmas trees.
P. S. Ate, who are often given a cold shower, are less likely to suffer from the spruce bark beetle. This, of course, is only possible in private plots, in parks, but not in the forest. Until now, this method helped me even when a bark beetle-typographer was feasting in the neighboring forest.
