Measure the lawn and calculate the square footage of the yard. Use 5 to 10 pounds of annual rye grass seed per 1,000 square feet.
Set the mowing height on the lawnmower to the lowest setting and mow the grass. Rake the lawn and dispose of the grass clippings.
Adjust the spread rate on the drop spreader according to the directions on the bag, then fill it with half of the rye grass seed.
Spread the seed starting along one edge of the lawn. Overlap the wheel marks on each pass for even distribution of rye grass seed.
Fill the drop spreader with the remaining seed and spread at right angles to the first pass with the drop spreader.
Sweep the grass with a stiff broom to knock the rye grass seeds onto the soil below the existing grass.
Spread organic fertilizer evenly over the entire lawn.
Water the grass well after overseeding and fertilizing, then water three times a day until you mow the grass for the first time.
