Patching the lawn with seed, sod, sprigs, plugs, stolons


When localized areas of dead or dying grass show up in your lawn, fix these by patching.

What to look for

  • Isolated damage caused by insects, diseases, or abiotic (environmental or nutritional) disorders
  • Localized areas invaded by weeds
  • Dead areas from an excess or lack of water as a result of poor coverage by sprinklers
  • Low areas allowing water to puddle instead of drain off
  • Burned spots caused by herbicide or fertilizer spills or dog urination

If the problem is localized, you can patch your lawn following the recommended steps. However before you begin, be sure to find the cause of the problem and solve it.
