Overview
Seeding rates vary based on the size and weight of individual seeds. Kentucky Bluegrass has tiny seeds (~1.4M per lb), requiring fewer pounds, while Tall Fescue has large seeds (~220K per lb), requiring more weight for the same coverage.

Pro Tips
New Lawn: Start with bare dirt or completely tilled soil for maximum seed-to-soil contact.
Overseeding: Apply seed over an existing lawn to fill in bare spots and improve density.
Watering: Keep the top 1/2 inch of soil moist (not soaked) until seeds germinate (typically 7-21 days).
Timing: For cool-season grasses (Fescue, Bluegrass), late summer to early fall is the best planting time.
