These are instructions for newly seeded lawns and are broad guidelines. More specific instructions would greatly depend on site conditions, weather & time of the season, but this is a good rule of thumb.

Watering
It’s best to keep the top inch of the newly seeded soil moist as often as possible. This will require frequent watering for short periods of time. As the lawn becomes more established the watering process will shift from short, frequent watering to less frequent, longer watering (run times). Eventually the lawn will be watered once every other day for a long period of time (20-40 min. depending on conditions).
WATERING NEWLY SEEDED LAWNS (season dependent)
Irrigate the new lawn 2–4 times daily for 5-20 minutes per area.
Allow the soil to become firm but not completely dried prior to watering again.
Watch seeded areas closely to see if watering times need adjustments.
Fertilization
A solid fertilization program will be necessary to establish the new lawn. All the seed will not grow at the same rate. It’s necessary to let the lawn grow 6 – 8 weeks before determining if reseeding areas is needed.
Lawn Grow-In Program
2-3 WEEKS AFTER SEEDING
Fertilize with Starter Fertilizer - look closely for areas that could need watering adjustments.
5-6 WEEKS AFTER SEEDING
Fertilize with Starter Fertilizer - look closely for areas that could need watering adjustments.
7-8 WEEKS AFTER SEEDING
Fertilize with Turf Builder and Spot Treat for Weeds - look closely for areas that could need watering adjustments.
10-11 WEEKS AFTER SEEDING
Pick up where you are in the season on the established program & follow it.
Mowing
The first mowing is typically 4-6 weeks after seeding. Some areas will need it more than other & there could be spots that won’t look great. It’s important to mow the lawn as usual – weekly even if it doesn’t look great. Do not let grass clippings clump over seeded areas. Mowing is a cultural tactic to reduce weeds & increase density of lawn seed.
Remember when seeding in the spring the seed will not fully establish before the hottest part of the season so the lawn may be just ok for the summer, not great. The lawn will recover & become fully in the fall months
