  • Lack of fertilizer: You may not have fed your lawn the right amount of fertilizer.
  • Disease: Disease and insects can affect grass growth. Powdery mildew or Japanese beetles can have an impact.
  • Shade: Too much shade can affect the overall health of your grass. Make sure you don’t have areas that are in constant shade all through the day.

  5. Cover the area with a thin layer of straw to stop birds eating your seeds

  2. Loosen the surface of your soil up to about 2-inches before overseeding the lawn. If you have compact soil, you can work in some organic matter or a thin layer of compost.
  3. Scatter your seeds across the surface. You do need to be sure you are using cool-season grasses or warm-season grasses that are suited to your region and the USDA hardiness tables.
  4. Scratch the seed into the surface to at least 1/4 of an inch. Lightly tamp the surface to make sure you have good contact.
  5. Add some fertilizer, which is formulated for new grass growth.
  6. Add a thin layer of mulch and water
