Taking care of your new, soon-to-be, lawn
After the hydroseed has been spread, allow it to dry for one day before starting your watering program. The lawn is especially vulnerable during the first two or three weeks. We recommend that if you’re installing sprinklers, do it before the seed is sprayed. Try to keep pets off as well.
Freshly seeded areas are thirsty and will need consistent watering. It’s usually recommended to water seedling roughly three to four times a day. This can be reduced once the grass starts growing. Don’t produce any puddles as this could damage the seeds.
Be sure to clear the area of weeds before seeding to help keep them out of the hydroseeded area, otherwise you’ll have to pull them by hand once the seedlings have securely rooted themselves. It can be tempting to try and use some sort of herbicide early, but avoid laying any type of chemical weedkiller until the lawn is matured.
After grass is established, wait until the grass height is roughly 3 1/4″ to 4″ before you mow. Fertilize 3-4 time annually with a good quality fertilizer. Due to the differences in PH levels and compaction in soil, it is common to have areas that are slow in germination process, so don’t panic if some areas take longer than others.
