New grass seed should be watered frequently to keep the soil consistently moist during germination. Generally, water new grass seed 2 to 4 times a day for 5 to 10 minutes per session, ensuring the top 1.5 to 2 inches of soil stays moist
. This frequent watering schedule is typically maintained for about 1 to 2 weeks until the seeds have sprouted
. After germination, reduce watering frequency but increase the duration to encourage deeper root growth. For example:
- Weeks 3 and 4: Water once daily, adding a second session on hot or dry days
- Weeks 5 and 6: Water every other day for about 40 minutes
- Weeks 6 to 8: Transition to a regular schedule of 1 to 1.5 inches of water weekly, divided into one or two watering sessions
Watering is best done in the early morning and late afternoon to minimize evaporation and avoid fungal growth caused by nighttime watering
. In summary:
- Water new grass seed 2-4 times daily for 5-10 minutes during the first 1-2 weeks.
- Gradually reduce frequency and increase watering time as grass develops.
- Aim for about 1 inch of water per week once established.
- Water early morning and late afternoon for best results.
This approach helps keep the soil moist without oversaturating it, promoting healthy germination and root development.
