GOOD TO KNOW
How much lawn seed should I buy?
Seed requirements depend on the grass species, climate and whether you are starting a new lawn or overseeding. Use the rate printed on your seed bag.
Example calculation
For 1,500 square feet at 5 pounds per 1,000 square feet, you need about 7.5 pounds of seed.
Tips for a better estimate
- Measure the actual usable space, not just the outer boundary.
- Double-check units and product packaging before ordering.
- Round purchases up where appropriate to avoid running short.
