Though Fall is the best time to seed a lawn, Spring is a close second and often an appropriate time to seed an area or over-seed to help lawns thicken up and out compete weeds. No matter what time of year you seed, being aware of how much water your newly seeded lawn is getting will help make your seeding a success!
Newly Seeded Lawn Watering Instructions
- The objective for the first 3 weeks is to keep the newly seeded area moist.
- Water with frequent, light watering for the first 10-21 days until the seed germinates. (Some bluegrass varieties can take up to 21 days to germinate!)
- If you have irrigation we would recommend watering 3 or 4 times a day for just a few minutes to keep the soil and seed moist. If you are manually watering that is not as easy to do, so watering lightly twice a day should still do the job and keeps the soil moist. Remember to water often, rather than deeply for the newly seeded lawn.
- Once the seeds have germinated and grown to about 2 inches you can water more deeply less often.
- Though it is important to keep the seeded area moist and not let it dry out during the time it is being established, it is also important not to over water. If you see puddles it is a good indication that you have overwatered and may have some of your seed washed away from the area you intended to plant. Overwatering can be just as damaging to a newly established lawn as under watering.
- If you miss a day all is not lost BUT you must get back on it, but again don’t over water to make up for lost time. Just moisten the soil so that about the top inch is moist.
- Keep an eye on the weather. Dry, windy days mean more frequent watering, cool, wet periods
Remember, once lawns are established they only need about 1-2" of water a week. Watering deeply, less often is the best way to water the established lawn. Using a rain gauge is a great way to monitor this!
In the heat of the summer you may choose to let your lawn go dormant in order to conserve water. Your lawn will naturally turn brown without additional water and assuming it's a healthy lawn, should recover nicely once the weather cools and it begins to receive moisture again.
