Scotts vs Pennington Grass Seed: Turf Builder Tall Fescue vs Kentucky 31

Last updated Researched from specs, manuals and owner reviews, not tested in person

Quick answer

Buy Pennington Kentucky 31 if you need the most seed for the money on a large lawn: a 40 lb bag covers up to 8,000 sq ft at under $100. Buy the Scotts Turf Builder Tall Fescue Mix for a smaller lawn where the built-in fertilizer and coating save a step: a 16 lb bag covers 1,330 sq ft of new lawn or 4,000 sq ft of overseeding.

Both bags are tall fescue, a cool-season grass that tolerates heat and drought better than most. The difference is the product around the seed. The Scotts Turf Builder Grass Seed Tall Fescue Mix, 16 lb (under $100) is a coated 3-in-1 mix with fertilizer and a soil improver, while the Pennington Kentucky 31 Tall Fescue Grass Seed, 40 lb (under $100) is a plain, economical bag of Kentucky 31.

Work out how much seed your lawn needs with the grass seed calculator before comparing bags, since you will buy by square foot, not by weight.
