Why is my Grass Turning Brown despite Watering?

The following are factors that can cause your lawn grass to turn brown despite watering:

1. Lawn Diseases

Lawn diseases will cause your grass to turn brown despite watering. Fungal infections are common cause of brown patches in your lawn. They are common in warm and moist conditions. They are usually present in the soil feeding on decomposing plant matters.

However, they will head up to grass when environmental conditions are hot and humid. If the fungus is not controlled, the small brown patches will grow into huge areas of dead grass.

2. Insects Infestation

White grubs and Chinch bugs are the common pests that cause brown patches in your lawn. Grubs will feed on tender roots of grass while Chinch bug chew on blades. Few white grubs won’t turn your lawn grass brown. However, an infestation will.

Grubs damage roots to cause poor absorption of water and nutrients. On the other hand, chinch bugs feed on the grass by sucking out the plant juice.

3. Nutritional Deficiency

If your lawn grass is turning brown, it may be suffering from certain nutritional deficiency. Grass require adequate nutrients to flourish. Deficiency of a certain nutrient such as nitrogen is characterized by browning and yellowing of grass blades. Conduct a soil test to determine which nutrient is inadequate.

4. Excess Soil Acidity

Lawn grass prefer a pH range of 6 to 7. Having tall evergreen trees in your lawn or mulching with fresh leaves can change the pH of the soil gradually. Conduct a pH test to determine the pH of your lawn soil.

5. Poor Mowing Techniques

Mowing too low will cause your grass to turn yellow and eventually brown. Excessive mowing significantly reduces the surface area of the leaf. The grass become unable to produce enough energy through photosynthesis to sustain themselves. Blunt mowing blade can also damage the edges.

6. Weeds Inversion

Weeds compete with grass for water, nutrients, light, space and other natural resources. When they take tall of your grass, they can smother and cause it to turn brown. They also host pests and diseases that attack grass.

7. Pet Waste

Allowing pets and stray dogs to excrete their waste on your grass will cause brown patches. Urine contain excess nitrogen that will literally burn the grass. Pets also like playing and burrowing holes on your lawn which can damage root to cause browning of grass.

8. Drought

Cool-season grass will enter dormancy during high summer temperatures. The grass will turn brown despite watering. It will come back to life when temperatures are cool.

How to fix Brown Grass Fast (Make it green)

If your grass is turning brown due to pests, diseases or poor soil quality, it’s ideal to evaluate your lawn so that you are able to pinpoint exactly what is causing this problem. Conduct a soil test to determine its nutritional value and the pH.

Soil test results will indicate the exact nutrient that is inadequate in the soil and the proportions needed to revive your brown grass. The result will also show the pH of the soil. Most lawn grass prefer soil pH range of 6 to 7.

If the soil it too acidic, you can reduce the acidity by adding lime. On the other hand, high alkalinity can be reduced by adding sulfur into the soil. The grass will come back to life within a few weeks of amending the soil.
