- Excess heat can cause the grass to dry out more quickly than normal and lead it to turn yellow. This is common if the root system of the lawn is very shallow. Heat radiation causes the upper grass to lose moisture and eventually turn yellow. A single very hot day or a week or two of unusually warm temperatures can generate this to happen.

Lawn Care Guide “Brown Patch is the most damaging turf grass disease” Brown patch is really a summer lawn disease that’s caused by a fungus called Rhizoctonia. The disease begins to show growth when temperatures reach 65°, but the most active growth of brown patch lawn disease occurs at temperatures of 80-85° when humidity levels are very high. The fungi survive the winter in plant debris (thatch) and enter the leaf tissue through wounds caused by mowing and through the pores (or stomata) when daytime temperatures get into the 70s.

- Brown Patch. Brown patch can be a problem in zoysia grass. Rhizoctonia fungus is often the culprit, caused by overfertilization. Fortunately, it does not kill the grass and zoysia is able to recover as it fills in during the warmer weather. Proper fertilization and watering helps to control this disease.oysia grass tends to produce thatch from dried cuttings and dead material that can cause brown patches on the lawn. This material can get quite thick and tangled and prevent fertilizer and moisture from reaching the soil and roots.

The reason why you may not be familiar with what thatch is is because it accumulates on the surface of your soil just below the grass line and usually out of sight. Thatch is a layer of grass stems, roots, clippings, and debris that settle on the ground and either slowly decompose and/or accumulate over time. Thatch buildup is commonly found in lawns where grass has grown tall, mulch is frequently left, and lawns that have never been aerated.

The water collects in the thatch layer and evaporates before it penetrates through to the root system.Thatch reduces the space available for producing new turf.hatch is primarily dead grass stems and roots which accumulate as grass plants die and are replaced. Thatch is not caused by grass clippings but by the woody, slow to decompose stems, rhizomes, and stolons below the grass blades.

Damage Identification Damage to turf by thatch inhabitants such as sod webworms, armyworms and cutworms is apparent when grass is cut off close to the ground. Damage by chinch bugs and spittlebugs, also thatch inhabitants, is similar to damage caused by soil inhabitants. Irregular spots of yellowish turf and dead spots may occur where chinch bug or spittlebug infestations go uncontrolled. Identifying your pest will save you time, money and your lawn.

How to Care for Burned Grass Burned grass occurs, most of the time, as a result of using a fast-release fertilizer on wet grass. The fertilizer does not have the chance to wash away in time and nitrogen burns the grass. Dog excrement and urine in small and large quantities can also burn grass, and so can road salt, as well as too much sun. Whatever the cause, the burns ruin the visual appeal of the lawn. In order to restore it, you must care for the spots, eradicating both the cause and the effect.
