Water is one of the key requirements for keeping a lawn green. It’s quite frustrating to realize brown patches in your lawn despite your daily efforts of keeping it hydrated. So, why is your grass turning brown despite watering?
Despite adequate watering, grass can turn brown as a result of diseases, pests infestation, nutritional deficiency, excess soil acidity, poor mowing techniques, weeds and burns from animals urine.
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.
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)
When you know what is ailing your grass, it is ideal to move with speed and fix the problem before it’s out of control. Here is how to fix brown grass fast:
1. Control threat of fungal infections
Refrain from watering your lawn late in the evening. Wet grass blades overnight will encourage growth of fungal infections. Be sure to water your grass early in the morning and late afternoon when the sun is still on.
If you notice the symptoms of fungal infections, apply a fungicide on the affected areas. Mowing your lawn weekly and aerating it twice a year can also help to reduce the chances of fungal infections.
2. Get rid of Grubs and Chinch bugs from your lawn
Grubs and Chinch bugs will spend entire summer munching on grass roots and juices respectively. To control these pests, apply chemical pesticides like carbaryl on the affected area. You can also control Grubs biologically by introducing nematodes into your lawn.
3. Fertilize your lawn appropriately
Conduct a soil text to determine the exact nutrient that is lacking in your soil. Soil text results also suggests the recommended quantities required by your grass. With proper fertilizer application, your lawn grass should be able to turn green fast.
4. Amend lawn soil to the recommended pH
Insert a pH meter into the soil to determine the exact pH value. Grass thrives in a pH range of 6 to 7, if it’s too low, amend the soil by applying lime to increase the pH. Roll the sod on the side and apply the lime. If it’s too high, lower it to the recommended range by applying sulfur.
5. Get rid of weeds in your lawn grass
Weeds compete with your grass for water, nutrients and other natural resources. Uproot all the present weeds in your lawn, apply re-emergent or herbicides to prevent new weeds from germinating. Timely weed control will promote green and healthy lawn grass.
6. Prevent pets and stray dogs from accessing your lawn
Provides your pets with alternative playground areas to reduce the chances of urinating on your grass. Installing motion sensor sprinklers in your lawn can also help to deter stray dogs from invading your lawn.
7. Mow your lawn grass appropriately
Mow your lawn at an appropriate height of 2½ inches to encourage green sprout growth. Also be sure to use a sharp mowing blade to minimize injuries on the leaf blades. Mow 3 inches and above in summer. Taller grass will shade roots and reduce water loss through evaporation.
Does grass come back after turning brown?

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.
