Thick'R Lawn Tall Fescue Mix - Overseed for Thicker, Greener Turf

Our review of Scotts Turf Builder Thick'R Lawn Tall Fescue Mix finds it best for homeowners with thin, patchy Tall Fescue lawns who want a simple, single-application approach to thicker, greener turf. The 3-in-1 formula combines grass seed, starter fertilizer, and a soil improver so you can overseed and feed in one pass, and each 12 lb. bag covers up to 1,200 sq. ft. In practice it simplifies routine overseeding in spring or late summer, and many customers report noticeably denser, healthier grass when they follow the prep and watering steps.

Key Features

• 3-in-1 formula: Seed, fertilizer and soil improver work together to fill bare spots while encouraging stronger root development for long-term lawn health.
• Tall Fescue blend: A mix designed specifically to thicken weak Tall Fescue stands and produce a fuller, more durable turf when established.
• Coverage per bag: Each 12 lb. bag treats about 1,200 sq. ft., making it straightforward to plan how many bags you need for small to mid-size yards.
• Simple application: The product is designed for use with a spreader and requires only basic prep: mow low, rake to loosen soil, apply, then keep soil consistently moist.
• Seasonal scheduling: Intended for overseeding once in spring and again in late summer or early fall to maximize germination and turf thickening.

Who It's For

This product suits homeowners with existing Tall Fescue lawns that have become thin, patchy or stressed and who want a low-effort way to overseed and feed at the same time. It is also useful for renters or DIYers who prefer a single product to reduce steps in routine lawn maintenance.

It is less appropriate for people starting a brand new lawn from bare soil without existing Tall Fescue, or for users who need an exact custom seed variety mix; results also depend on proper prep and watering, so those unable to follow aftercare may see mixed germination outcomes.
