New grass seed requires frequent watering to keep the soil consistently moist, especially during the germination period. Here is a detailed watering schedule based on expert guidance:

Watering Frequency for New Grass Seed

• First 1 to 2 weeks (Germination phase): Water new grass seed 2 to 4 times daily for about 5 to 10 minutes per session. The goal is to keep the top 1.5 to 2 inches of soil moist at all times to encourage seed sprouting

• Weeks 3 and 4: Once the grass has started to sprout, reduce watering to once daily , or add a second session during hot, dry days. Increase watering duration to about 20 to 30 minutes per session, twice a day to promote deeper root growth

• Weeks 5 and 6: Water less frequently but more deeply, about every other day for 40 minutes , eventually lowering to watering 2 to 3 times per week. This helps establish stronger roots

• Weeks 6 to 8 and beyond: Your grass should be established enough to transition to a regular lawn watering schedule, typically 1 to 1.5 inches of water weekly in one or two sessions

Additional Tips

• Water early in the morning or in the early evening when temperatures are cooler to reduce evaporation and prevent grass burn

• Avoid overwatering to the point where water pools on the soil surface, as this can wash away seeds or cause them to float

• For bare spots or patchy areas, water those spots more frequently (2 to 4 times daily) until germination, while watering the rest of the lawn as usual

• Continue frequent watering until the grass reaches about 4 inches tall, then gradually reduce frequency and switch to deeper, less frequent watering

In summary, newly seeded grass needs frequent, light watering multiple times daily for the first couple of weeks, then gradually less frequent but deeper watering as the grass matures and roots develop
