First and second week after your aeration: Shallow, daily watering. Water daily and if possible, two times per day – once in the morning and once in the late afternoon. The main goal is to keep the seed wet. If you have an irrigation system, 10-20 minutes per watering should be adequate depending on your sprinkler output. If using a hose sprinkler, be sure to move the sprinkler to multiple locations in the yard to ensure even and thorough watering or use a multi-valve hose timer with multiple hoses and sprinklers. 10-15 minutes per station should be adequate. Avoid heavy watering during this stage as it can wash the seed away. If the water is puddling, shorten the time per watering.
Third to fourth week after aeration: Water longer but less often. The seed should be germinating by this point. Deep soakings are the objective now, allowing the roots to develop and reach further in the ground before winter and colder weather stunt its development. Decrease watering to 2-3 days a week. Increase your time by 5-10 minutes per watering. Only skip your watering schedule after a rainfall if it was a deep soaking rain (1/2”–1”).
Fescue can take twenty one (21) days to germinate.
Don’t mow your lawn for about two weeks after your aeration. New grass is tender and tends to pluck out rather than cut if mowed too soon.
If we maintain your lawn, we will skip mowing for about two weeks to allow the newly seeded grass a chance to germinate and take hold before putting any stress on it. We will still visit weekly to edge and check on the seed’s progress.
It is our policy that if a rogue storm washes the seed away, we will perform the service again at cost.
We will provide wheat straw where lawn is bare for $10.00 per bale upon request. This is a complementary service to our maintenance customers under contract. (Please note – wheat straw can germinate).
Be diligent in your watering and results will follow.
