Fixing Brown Spots On Lawn
Brown spots appearing on the lawn can occur even with the most well maintained lawns. One can successfully treat the brown spots as long as the exact cause is correctly identified. There are many causes of these brown spots and to identify the specific cause of damage on one's lawn requires vigilance and being familiar with one’s lawn and maintenance schedule.
Brown spots happen either as a cause of moisture loss or a fungal attack, which are both the result of insufficient watering. One must assess the current watering schedule, and check if it meets the minimum water requirement of one’s grass type. If the brown spots on lawn surfaces have yellow edges or if there are yellowish spots on the grass blades, the grass is experiencing fungal attack. In this case, one needs to apply a fungicide that that contains sulfur. Follow manufacturer's instructions as to the amount required and apply the fungicide every five days. Mow the grass to cut off the infected parts.
Improper mowing practices such as mowing too low or using dull mowing blades also cause brown spots occurrence. Follow the proper mowing height recommended for grass type in order to avoid stressing the grass and weak root growth, which will result in brown spots on lawn. If the weather is too hot, cut high in order to keep moisture in. Use sharp mowing blades at all times. Dull blades will fray the grass, which will in turn make the grass tips brown.
Treating brown spots that are caused by dog urine requires monitoring one's dog and correcting his urine habits. As soon as one sees the dog urinating on the grass, dilute the spot with water right away. Train the dog not to urinate on the lawn by providing him a place where to he can do this. Brown spots on lawn can also be achieved by keeping the dog off the lawn altogether. Planting stakes and lining the lawn perimeter with chicken wire is one way of doing this.
A brown spot that appears right after fertilizer application indicates chemical burn or fertilizer overdose. Douse the affected area with water immediately to dilute the fertilizer. For future applications, follow the packaging instructions to the letter to avoid recurrence. If one is not sure on the amount to apply, it is better to err on the side of applying less fertilizer than more.
Grass covered for a long time also results in brown spots on lawn. Objects left on the lawn, thatch buildup and accumulated debris all inhibit the grass from receiving the sunlight that it needs. Periodically one has to run a rake over the lawn to remove thatch buildup, plant debris, twigs, and rocks. Remove things left on the lawn like equipment and children's toys. When these are removed as soon as possible the grass will recover easily. If left for too long, the grass will die out and patching will be necessary.
If one's best efforts to remedy the situation are not enough, replacement is necessary. Dig up the brown spots on lawn or damaged area to expose a fresh layer of soil. Grass replacement can be done by spreading grass seed or planting new grass sods.
