Water your lawn area for two to four days to encourage weed growth. Weeds that are vigorously growing are easier to kill than dormant weeds, because they absorb the toxins from the herbicide through their leaves.
Spray your lawn with a herbicide that contains glyphosate on a dry day. Remove all vegetation from the yard area. Vegetation such as weeds competes with the grass for sunlight, air and the soil's nutrients. Cover surrounding ornamental plants with a piece of plastic to protect them from the spray of the herbicide.
Break up the first 6 inches of top soil with a tiller. Root systems have a hard time breaking through compacted soil. Use a rake to create a slight slope from the house out to the street or driveway. Grass should never be sitting in standing water.
Pour a starter fertilizer into your rotary fertilizer spreader. Use a starter fertilizer with a NPK amount of 5-20-10 and apply 20 lbs. per 1,000 square feet. Work the fertilizer into the first 2 to 4 inches of top soil. Water the area.
Water the lawn area, but avoid saturating the soil. Seeds need moist soil in order to germinate.
