One sqft plots of an old lawn were overseeded with 1, 2, 3 and 4 teaspoons of seed. This corresponds to about 10, 20, 30 and 40 pounds per thousand sqft. Seed was sown on August 29, 2019, and the photo was taken on the 11th day, Sept 9. There was no soil preparation. There was no irrigation. Rain was light and irregular. Temperatures mostly between 70 and 80 F as afternoon highs. New grass was visible at all the different seeding rates. Heavier rates of seed resulted in seed sprouting, with greater density.
