To properly water grass seed for optimal germination and growth, follow this general schedule:

• Initial Phase (First 1-2 weeks): Water new grass seed 2 to 4 times daily for about 5 to 10 minutes each session. This frequent, light watering keeps the top 1.5 to 2 inches of soil consistently moist, which is crucial for seed germination. Use a mist or gentle sprinkler to avoid dislodging seeds or causing runoff. This schedule typically continues until the seeds have sprouted fully

• After Germination (Weeks 3-4): Reduce watering frequency to once daily, with an additional watering on hot or dry days. Watering sessions can be longer to encourage deeper root growth, but the soil should not be waterlogged

• Establishment Phase (Weeks 5-6): Water deeply about every other day for approximately 40 minutes. This helps grass develop strong, deep roots. Gradually reduce watering to 2-3 times per week as roots establish

• Mature Lawn (Weeks 6-8 and beyond): Transition to a regular watering schedule of 1 to 1.5 inches of water per week, applied in one or two sessions. This supports healthy lawn maintenance

Additional Tips:

• Keep the seedbed moist but avoid standing water to prevent seed rot or washout

• Adjust watering frequency based on weather conditions: increase watering on hot, sunny, or windy days, and reduce or skip watering after rainfall

• Water early in the morning and late afternoon to minimize evaporation and fungal issues

• Using a thin layer of straw mulch can help retain moisture and protect seeds

In summary, water new grass seed frequently and lightly at first to maintain moisture, then gradually reduce frequency and increase duration as the grass establishes deeper roots
