If the grass changes color, then that is a good sign there is a problem. Quality Turf uses its 30 years of experience to provide you with great grass that is ready to grow, but sometimes outside conditions can affect your grass after it has been installed. Use this troubleshooting guide to get you started, but please call us with specific questions. We are happy to help!

Problem: My grass has brown spots.


  1. Increase watering. Brown spots could be caused by a number of problems, but the most common is usually that the grass is not getting enough water. Be sure that your sprinkler is reaching that particular spot or increase your overall watering time by a few minutes each day.
  2. It could have also been caused by a chemical spill, like from pesticide, fertilizer, or gasoline. Be sure that you handle equipment carefully and use no-spill containers and funnels. Flood the area with water to dilute the spill and remove it with an absorbent product. You may also need to repair that area or reseed.
  3. Pet urine. Pet urine often causes brown spots in the grass, especially if your pet tends to visit the same spots frequently. Increase the watering time for those places or hand water each spot to dilute.
  4. Excessive pesticide use. Using too much product on the grass ban “burn” it, making it turn brown or yellow. Be sure that you are following the product instructions.


Problem: My grass has yellow spots.


  1. Decrease watering. Usually, when grass turns yellow it because you have been overwatering. Cut down watering time just a few minutes each day until the grass becomes its natural color again.
  2. Spills can also be the cause of yellow spots. See the brown spot remedy above for how to treat these areas.
  3. Decreased nitrogen. Lawns that do not have enough nitrogen may turn yellow or light green. The color change generally starts toward the bottom. Fertilizing may help with this problem, but be sure to follow the product instructions carefully. Leaving grass clippings on the lawn after mowing may also help increase the nitrogen levels in the lawn naturally. Avoid adding fertilizers with high nitrogen content in the very hot weather as it could damage the grass.
  4. Iron deficiency. This cause will usually occur near driveways and sidewalks. Try using a soil supplement on these areas. Be sure that you follow the packages instructions and remove the product from concrete or brick areas to avoid staining.

Problem: My grass has webs or grey spots.

Solution: Treat the fungus.

Grass that has webbing or gray spots probably has a fungus. Use a fungicide to combat this problem as soon as possible. Fungus can spread quickly, so head to a local garden store and speak with a clerk about the best fungicide for your particular situation.

Problem: I have weeds OR I think my lawn has a disease/pest infection.

David at qturf really stepped it up for us. He was so patient and helpful with all of our needs. My only regret is not redoing or yard sooner!  The prices are competitive and the sod is absolutely gorgeous. Our gardener was so impressed with the quality. Here we are, one year later, and we are STILL the envy of our neighbors!
