Seed bag coverage dataset, 2026

Manufacturer coverage claims for 43 retail grass seed products, collected from public retail listings on September 7, 2026. Where a listing states separate new-lawn and overseeding coverage figures, both are recorded. Single-species products are compared against university extension seeding rates. Products sold as mixes are excluded from that comparison. Coating status is recorded with its source. Files: seed-bag-coverage-2026.csv (the data) and README-dataset.md (column definitions, methodology and limits). Analysis and findings: https://lawnseedpicker.com/seed-bag-coverage-claims
