How Much Grass Seed Do I Need Per Acre?
A newly seeded pasture or large field requires 50 to 100 pounds of grass seed per acre. For an established field that has bare patches, use 20 to 30 pounds of grass seed to over-seed each acre. Rake the seed so that it is lightly covered up to 1/2 inch.
Water the newly seeded area every two days until the grass is 6 inches tall, then reduce watering to three times a week. Apply 250 pounds of fertilizer per acre three months after planting, and apply the same amount three times each year. Maintain established pasture grass at 6 to 10 inches high.
