Scotts Turf Builder Thick'R Lawn Sun & Shade Overseed + Fertilizer, 40 lb — Treats 4,000 sq ft

If your lawn has bare patches, thin areas, or weak root structure, this all‑in‑one product combines grass seed, balanced fertilizer and a soil improving base to simplify renovation. One 40 lb bag treats up to 4,000 sq. ft. and is formulated for both sunny and shaded areas, making it a practical choice for homeowners who want visible thickening without juggling multiple products.

How do I use this product to repair thin spots effectively?

Repairing thin areas is a three‑step process: mow short, loosen the soil, apply the product with a spreader, then keep the surface consistently moist until seedlings establish. Timing matters — apply once in late spring and again in late summer or early fall for best seasonal germination.

• Mow to about 2 inches or the lowest safe mower setting before application.
• Rake to remove debris and loosen the topsoil so seed contacts soil.
• Use a Scotts spreader with label settings for even coverage.
• Water daily to keep seedbed moist for approximately two weeks, then water regularly.

What results can I expect and how quickly will I see change?

Germination speed depends on temperature, moisture and existing lawn health, but you should see seedlings emerge within one to three weeks under proper watering. With proper care, the product can help create a noticeably thicker lawn over a full growing season; individual outcomes vary based on lawn condition and follow‑up maintenance.

• Seed begins to germinate in warm, consistently moist conditions — often within 7–21 days.
• Fertilizer provides nutrients to support young plants and encourage denser growth.
• Soil improver supports root development for longer‑term resilience.

Can I use Scotts Thick'R Lawn on both sunny and shady areas?

Yes — the seed blend and nutrients are selected for adaptability across sun and shade microclimates commonly found in home lawns. For very deep shade or highly compacted soil, additional site‑specific steps (thinning tree canopy or core aeration) can improve long‑term success.

• Formulated for mixed light conditions to establish grass in sun and partial shade.
• Combine with aeration or pruning where soil compaction or dense shade limits growth.
• Follow label water and spreader instructions for uniform results across different areas.

How much area does one 40 lb bag cover and what tools do I need?

One 40 lb bag covers up to 4,000 square feet when applied with a spreader using the recommended settings. A broadcast or drop spreader, a rake, and a hose or irrigation system for consistent watering are the only essentials for a proper application.

• Coverage: up to 4,000 sq. ft. per 40 lb bag.
• Tools: Scotts spreader (recommended), rake, mower and watering source.
• Apply evenly and follow label rates to avoid over‑application in small areas.
