Anyone who has a space in the garden with grass or is in charge of the care of some area of grass, has more than once encountered the dreaded yellow spots. This problem, which can have many causes, is one of the most headaches for gardeners and gardening enthusiasts around the world, but luckily there is always a solution.
If you want to know why the lawn turns yellow and what are the most important lawn care for it to improve, join us in this Green Ecologist article in which we clarify the causes of yellow grass and how to get it back.
Yellow grass due to excess temperatures
There are a large number of species and varieties of grass, each one suitable for certain climates and conditions. If you live in a warm and your lawn is exposed to direct sunIt is very possible that you will find large yellow areas where the light is most incident, especially at noon.
The lawn gets very stressed under the intense sun and the species or varieties that are not prepared for very hot environments do it even more. Pay close attention to the characteristics of your climate before planting the grass and make sure that the needs of this are adapted to what you can provide.
Yellow grass due to drought
In the same way that an excess of sun can weaken the lawn and make it yellow, a lack of water will have a very similar effect: dry, yellow, brittle grass. Again, each type of lawn has very different irrigation needs, and these are greatly affected by soil drainage and the climate in the area. Pay attention to how you water, trying do not leave areas without water and not other flooded ones, and to the possible unevenness of the terrain, which can cause the water to concentrate at certain points.
Sick lawn due to waterlogging
If it is possible that the lawn is yellow due to lack of watering, it is also possible that the opposite occurs. People without much experience with gardening tend to think that the more water a plant receives, the better for it, but those of us who have been in this for a while know that excess water tends to be more dangerous than lack of it.
When the ground gets puddled or flooded, the roots lose the ability to breathe, and tend to rot quickly. Without a root system to feed it, the aerial part of the plant is left without a source of food, and it does not take long to die. In addition, excess humidity tends to promote the appearance of all kinds of mushrooms, especially in warm or temperate temperatures, which will quickly attack the lawn and leave yellow zones.
Yellow grass due to lack of sun
Yes there are trees in the area in which you have planted the grass, it is possible that some of them do too much shade on a certain area of the grass that, if it is deprived of light for many hours a day, can end up yellowing and drying out. It is even possible that the tree's roots have spread superficially under the lawn and are depriving it of water or nutrients.
Yellow grass due to excess nitrogen
Nitrogen is one of the main plant nutrients, and also one of the elements in which almost all fertilizers are richer. However, although nitrogen is essential for the development of vegetation, an excess of this changes soil pH and burns roots.
Yes your lawn yellows evenly you are probably overpaying, so you should reduce the dose of fertilizer or look for one less rich in nitrogen. The excess of the other elements is usually much less important, and it takes really large amounts to be a problem.
Another substance very rich in nitrogen is urine. If one or more dogs frequently urinate on a certain area of the lawn, the characteristic yellow spots bordered with green will end up, in which the outer area is rich enough in nitrogen to compost the lawn, but in the center the concentration is excessive and has burned the grass.
How to recover yellow grass
Once you have found the reason for your sick lawn, do your best to change that element that is damaging it.
- If your lawn is getting too much sun, water it more often it can help.
- It is also possible that the ground has become very compacted due to the passage of time: treading on and the accumulation of dead roots can make the soil impervious, and it is necessary scarify the ground to aerate it, usually at the end of summer and winter.
- You should also make sure that your lawn is not under the fungal attack and if so, you can treat them with some antifungal, always preferably homemade and organic, they are very easy to make.
