If you know you are watering well, but still see edges of lawn near the sidewalk and driveway that look dry and wilted, you might have chinch bugs. Here’s a quick video on how to identify.
Once you determine that chinch bugs are present, you can treat with hose-end Cyonara or Diatomaceaus Earth for an organic control.
Keep in mind: Chinch bugs are more likely to attack a dry stressed lawn before a healthy, well-hydrated lawn. Give lawns a deep drink (a good 1” of water) once a week, in the morning. Deep drinks encourage roots to grow deeper, which makes lawns more resilient to dry conditions and to pests.
