Although maintaining a lush green lawn is laborious and time consuming, the envious praise of neighbors is well worth it. Keep a vigilant eye on your grass at all times to prevent weeds, insect damage, dog urine marks and brown or bare patches from taking over. Sometimes, despite your best efforts, you may find brown spots or patches in the lawn. It is essential that you diagnose the problem to prevent it from getting out of hand and deteriorating the appearance of the lawn.
Identify the cause of the problem. Heavy foot traffic compresses grass that eventually turns brown due to lack of oxygen and sunlight. Divert traffic off your lawn, or lay stepping-stones as an alternative route. Remove any heavy objects on the grass such as children's play equipment and move them somewhere else.
Spray non-toxic solution over the brown spots if your canine's urination habits are causing your grass to turn brown. The enzymes in the spray break down the urine and dilute it so the grass grows back green.
Apply a sulfur fungicide if your lawn has brown patch lawn disease. This fungal disease causes brown spots with a 2-foot diameter that are surrounded by a ring of discolored grass. Follow label instructions for directions.
Check the lawn for uniform brown spots if you fertilized it recently. The high nitrogen content in fertilizers burns grass, which is why feeding grass in the summer is prohibited. Douse the brown grass with water to dilute concentrated amounts of fertilizer.
Water your lawn including brown grassy patches at least twice a week, preferably early in the morning. Keep the garden hose on for up to an hour so the water reaches 3 to 4 inches below the soil. You can also install an automatic sprinkler system that turns on itself for a specific amount of time. Proper hydration is the key to turning brown grass green again.
Sprinkle rye grass seeds over brown grass in the winter. Rye grass is a cool weather grass that dies in the summer months. Water the seeds well and cover with a layer of mulch. Water twice a day for two to three weeks until the seeds germinate and grow into a thick green winter lawn.
