Care and Watering
However your new lawn is installed, care is very important, particularly for the first month.
Successful seed germination depends on a few days of special care. To assure proper germination, water regularly. We suggest two times a day in warm weather. Keeping the yard moist will maximize seed germination.
You may walk on the hydroseeded surface when watering. Try to walk only on areas that are dry, and try to not disturb the mulch mat.
By watering regularly and keeping your new seedlings from drying out you insure the beginnings of a lawn that will make your neighbors green with envy.
Mowing
Mowing can begin once the new lawn is 3" tall in most areas. Mowing stimulates growth and increases thickness. Set the mower high at first, then gradually lower. Try to cut no more than 1/3 of the grass at a time.
One general rule for mowing is that the shorter you want to mow the more often you need to mow to maintain healthy grass.
Fertilizing
About one month after seeding, fertilize your new lawn using a high nitrogen (the first of the 3 numbers on the bag) fertilizer. The contractor who installed your lawn used a high phosphorus or "starter fertilizer" when hydroseeding your lawn. The phosphorus will stimulate root growth, and in the early stages it is important to get good root growth before you stimulate a vigorous top growth with nitrogen.
Continued Care
Talk to your landscape professional to see if he has a program for continued care of your lawn with regular treatments of fertilizer and treatments for weed and insect problems as required.
