The most important thing to remember for your new lawn to succeed is to KEEP IT WATERED.
Keep your lawn wet for the first two weeks by watering each area daily. It should feel moist and not dried out. Morning or afternoon watering is best, but evening is ok if necessary until grass germinates.
You can leave the sprinkler in one place for up to three hours but move it if you see water running off the lawn or big puddles.
Start with 30 minutes per zone and run through the zones multiple times per day as needed to keep the lawn wet. If you see puddles or washout, decrease the amount of time per zone and increase the number of times you run through the zones daily.
Increase you’re watering time per area by 50% but cut back to watering every other day. Water in the morning or afternoon, not the evening.
Soak each area of the lawn every other day for up to four hours but move it if you see water running off the lawn or big puddles.
Double the amount of time per zone you’re watering, but water every other day instead of daily. Decrease watering time if you see water running off or big puddles.
Water once per week with about 1 inch of water per day to help develop deep roots and prepare the lawn for winter. Depending upon your system this could be 60-120 minutes per area per day. You can stop when we’re getting regular rainfall.
If we used straw, don’t worry, it will naturally decompose on its own. If we didn’t use straw, we used a mixture that holds the seed in place, naturally decomposes, and improves the soil.
We put down plenty of seed for the birds to have a bit. Don’t worry about birds, they won’t negatively impact the seeding.
Wait is 3” -4” tall before mowing and then cut it at about 3”. After that, just mow as you normally would, gradually decreasing height to 2.5” as the grass stops growing in the late fall.
Do not water more than once per week. Watering deeply and infrequently will make it more difficult for undesirable grasses to return.
