Lawn dimensions
Multiply length by width for rectangular areas. For irregular lawns, break into rectangles and add them up. Or measure with the Google Maps area tool.
Seeding rates by grass type
Rates below are per 1,000 sq ft, pulled from Penn State Extension lawn seeding guide, NC State Turfgrass Files, and Texas A&M AgriLife turfgrass research.

|---|---|---|
| Kentucky bluegrass | 2-3 lb | 1-2 lb |

Fertilizer and lime rates
Annual fertilizer for established lawn: cool-season needs 2-4 lb actual nitrogen per 1,000 sq ft per year, split across 2-4 applications. Warm-season: 2-6 lb N per year. Lime: applied when soil pH drops below 6.0 for cool-season or 6.5 for warm-season. Standard rate: 50 lb pelletized lime per 1,000 sq ft to raise pH ~0.5 points. Get a real soil test first; don't apply lime blindly.
