Overseeding your lawn in Oregon is a great way to fill in bare or patchy areas with new grass. However, to ensure the seeds germinate and grow into healthy grass, you need to follow an ideal watering schedule. For the first two weeks, you'll want to water your lawn 2-4 times a day, but with lighter watering to keep the soil moist without drowning the seeds. From weeks two to four, you'll want to water your lawn less frequently, about 1-2 times a day, but with more water during each session. After a month, you can go back to your normal watering schedule.

For the first 2ish weeks after overseeding your lawn, it is crucial to establish a consistent watering routine. During this period, you'll want to water your lawn 2-4 times a day. However, it is important to note that these watering sessions should be lighter to avoid drowning the seeds. The goal is to keep the soil consistently moist, which will help the seeds germinate and establish their root systems.

By watering your lawn multiple times a day, you ensure that the seeds receive the necessary moisture to sprout and grow. However, it is important to avoid overwatering, as this can lead to waterlogged soil and hinder the development of the new grass. Light and frequent watering during this initial period will provide the seeds with the ideal conditions for successful germination.


From 2-4 weeks after overseeding, you'll want to water your lawn 1-2 times a day.

As the grass seeds begin to sprout and establish themselves in the soil, you can gradually adjust your watering schedule. From weeks two to four after overseeding, you'll want to water your lawn 1-2 times a day. However, during each watering session, you should provide more water to ensure deeper penetration into the soil.

By reducing the frequency of watering but increasing the amount of water provided, you encourage the development of deeper root systems. Deeper roots help the grass withstand environmental stressors such as drought and foot traffic. It is important to monitor the moisture levels in the soil during this period and adjust the watering schedule accordingly to maintain optimal hydration for the growing grass.

If you overseed your lawn, you should also invest in a lawn fertilization treatment to give the new grass the nutrients it needs to thrive.

A month after overseeding, you can return to your normal watering schedule.

After approximately one month from the overseeding process, your grass should have established a strong root system and be well on its way to becoming a lush and healthy lawn. At this point, you can gradually transition back to your normal watering schedule.

Returning to your regular watering routine means providing your lawn with a deep watering session once or twice a week. This allows the roots to continue growing deeper into the soil, promoting a resilient and drought-tolerant lawn. By maintaining a consistent watering schedule, you ensure that your grass receives the moisture it needs to thrive while avoiding overwatering, which can lead to shallow root growth and other issues.
