  • Spread the seed evenly using a seed spreader and lightly rake it into the soil.
  • Water the seeded area regularly to keep the soil moist for successful germination.

2. Watering

  • Kentucky bluegrass requires approximately 1 to 1.5 inches of water per week, either from rainfall or irrigation.

  • Monitor the lawn regularly and promptly address any weed issues through targeted herbicide applications or manual removal.
  • Practice proper lawn care techniques to maintain a healthy grass stand, minimizing opportunities for pests and diseases to thrive.
  • Consider using integrated pest management (IPM) strategies to identify, monitor, and control pests effectively.
