Getting a new lawn started with grass seed is an exciting step toward a beautiful outdoor space. However, one of the biggest challenges is figuring out how often to water new grass seed. Proper watering is essential for helping your seeds germinate and grow into a healthy, vibrant lawn. Too little water can leave the seeds dry and struggling, while too much can cause issues like seed rot or shallow roots.

Grass seed should be watered lightly 2 to 3 times daily during the first two weeks to keep the topsoil consistently moist. Once the seeds begin to germinate (around weeks 3–4), reduce watering to once daily or every other day. After the grass is established (week 5 and beyond), water 1–2 times per week with a deeper soak to promote strong root growth. To maintain a healthy lawn, consider pairing proper watering with a professional grass trimming service for a well-groomed and vibrant appearance.
