use a shovel or something to push the dirt around and even out your yard so it isn't all dippy.

go through and pick out any left over roots and rocks from the soil.

walk over the seeds to press them down in to the soil.

water the grass every day to keep consistently moist for the first week.

water every other day, or when the soil begins looking too dry during the second week.

if it is growing in patchy, don't fret! the grass will eventually spread on its own to fill your entire yard.

it can take months before your yard fills in perfectly. be sure not to walk on it for at least 2 months so the roots can take hold.
