The lawn is an important element of any garden, so it must be resistant, green, strong and neat. Any kind of disease will not only affect its appearance, but also its health.
In properly maintained lawn, diseases are normally isolated, occurring very rarely, or limited to very small areas. The chance of diseases is higher after or during rainy periods, as well as in the case of young lawns (under 12 months old). Diseases usually manifest in the form of abnormalities that have a circular and regular shape, or as spots on the grass blades.
Brown spots or discolorations can be caused by several factors.
They can be the result of excessive fertilization or uneven spread of fertilizer. These substances used in excess can burn the grass, causing its death. The solution, in this case, is moderate fertilization, at least for a while, and abundant irrigation of the lawn. A large amount of water will help dilute the fertilizer and spread it deeper into the soil.
Nitrogen in pet urine also causes similar problems, since it has a high concentration of nitrogen, which will be felt by the respective area of the lawn as an overfertilization. In this case, the diet of the animal as well as training to focus urinating to specific areas will help prevent the problem.
On the other hand, brown patches on lawn can also be the result of insufficient fertilization and lack of nutrients. So, the key word, when it comes to fertilization, is “balanced.”
