Watering for Reseed and the Fall: Maximizing Germination and Lawn Health

As the cooler temperatures of fall settle in, it’s easy to assume that your lawn doesn’t need as much attention as it did during the hot summer months. However, fall is a critical time for lawn care, especially for reseeding. Proper watering is essential to maximize seed germination and ensure the health of your lawn going into winter. In this blog post, we'll discuss how to water your lawn during the fall, with specific tips for those who have recently overseeded.

Why Fall Watering is Crucial

Fall provides an excellent opportunity for reseeding and revitalizing your lawn. The cooler temperatures and increased rainfall create ideal conditions for seed germination and root growth. However, without proper watering, your efforts could go to waste. Consistent moisture is key to helping new seeds establish and ensuring your lawn remains healthy.


Maximizing Germination for Reseeded Lawns

When reseeding, the goal is to keep the top layer of soil consistently moist to encourage seed germination. Here's how to do it:


  1. Initial Watering: Immediately after overseeding, water your lawn thoroughly to ensure the seeds make good contact with the soil. This initial soaking is crucial for seed-to-soil contact.

  2. Frequent Light Watering: For the first 2-3 weeks, water lightly but frequently. Aim for 7-10 minutes of watering in the early morning and another 5-7 minutes in the late afternoon. This keeps the soil moist without washing away the seeds.

  3. Gradual Transition: After the seeds have germinated and the new grass has been cut once, gradually transition to less frequent but deeper watering. This change in watering schedule typically takes place 5 to 7 weeks after your reseed is completed. At this time you should begin watering every other day in the morning only unless temperatures are forecasted above 85 degrees. This encourages the roots to grow deeper into the soil.


Watering Schedule for Reseed

  1. Week 1-3: Water for 7-10 minutes in the morning and 5-7 minutes in the afternoon. .

  2. Week 4-5: Water for 10-15 minutes once daily (preferably in the morning).

  3. Week 5 and Beyond: Water for 10-20 minutes every other day, depending on rainfall and soil moisture levels.


General Fall Watering Schedule

Even if you haven't reseeded, your lawn still needs adequate water during the fall to stay healthy. Here's a general watering schedule for fall:

  1. Early Fall: Water for 10-20 minutes or long enough to provide 1.5-2” of total irrigation, 2-3 times per week. Adjust based on rainfall.

  2. Mid to Late Fall: Water for 10-20 minutes, 3-4 times per week. Again, adjust based on rainfall and soil moisture.


Adjusting for Increased Seasonal Rainfall

One of the great things about fall is the increased rainfall, which can help reduce the need for supplemental watering. However, it's essential to monitor your lawn and adjust your watering schedule accordingly. If you receive significant rainfall, you can reduce the frequency of watering. Use a rain gauge to track how much rain your lawn gets and aim for a total of 1.5 - 2 inches of water per week from both rainfall and irrigation.


Tips for Effective Fall Watering

  1. Morning Watering: Watering in the morning is ideal because it allows the grass to dry out during the day, reducing the risk of disease.

  2. Avoid Overwatering: Overwatering can lead to shallow root systems and increased susceptibility to disease. Adjust your watering schedule based on the weather and soil moisture.

  3. Check Soil Moisture: Use a soil moisture meter or simply stick your finger into the soil to check for moisture. If the soil feels dry, it's time to water.


Fall is a crucial time for lawn care, especially if you've overseeded. Proper watering ensures that your new seeds germinate and that your lawn remains healthy as it prepares for winter. By following the watering schedules and tips outlined above, you can maximize seed germination and maintain a lush, green lawn throughout the fall.
