Scotts Turf Builder Rapid Grass Sun & Shade Mix 16 lb — Fast‑germinating seed with starter fertilizer for sun & shade

Scotts Turf Builder Rapid Grass Sun & Shade Mix is a combined grass seed and starter fertilizer that establishes green, full lawns faster than seed alone.

This 16 lb. bag blends multiple grass varieties with a built-in fertilizer to speed early growth across both sunny and shaded areas. Designed for new lawns or overseeding worn spots, the formula promotes quicker germination and feeding when applied under recommended conditions. Coverage is generous: about 2,395 sq ft for new lawn installation and up to 8,000 sq ft for overseeding. Use a spreader for even application and avoid weed controls until the grass has been mowed four times.

How quickly will I see new grass after applying this mix?

Expect visible greening and blade development in a matter of weeks under ideal conditions. The integrated starter fertilizer supports faster early growth than plain seed, especially when soil temperatures and moisture are maintained.

• Grows up to twice as fast as seed alone when applied at the new-lawn rate*
• Best results when temperatures are consistently 60–80°F
• Keep soil moist until seedlings establish
• Avoid mowing until seedlings reach recommended height and have been cut four times before weed control

Where should I use Scotts Turf Builder Rapid Grass Sun & Shade Mix?

This product is formulated for both full-sun and partly shaded lawns, making it suitable for varied yard conditions. Use it to start a new lawn, repair bare patches, or overseed larger thin areas to restore density.

• New lawn installations—apply at the new lawn rate for maximum feed
• Overseeding thin or high-traffic areas to thicken turf
• Works across a range of sun exposures, from sunny lawns to shaded understories
• Use a Scotts spreader for uniform coverage

How do I apply and care for the seeded area for best results?

Preparation and consistent watering are key. Lightly rake, remove debris, and level the soil; then apply seed with a spreader and keep the surface evenly moist until seedlings are established.

• Apply in spring or fall when air temperatures are 60–80°F
• Water lightly and frequently until turf is established, then reduce frequency while increasing depth
• Avoid weed control products until you’ve mowed seedlings four times
• Feed with Scotts lawn products every 8 weeks during the growing season for ongoing health
