Description Get outside and enjoy your lawn with Scotts Turf Builder Rapid Grass Tall Fescue Mix. With our unique, proprietary mix of seed and fertilizer in one effective formula, your lawn benefits from extended feeding, resulting in full green grass! Compared to seed alone, your lawn will grow 2 times faster (when applied at the new lawn rate, subject to proper care). Use on either new lawns or overseeding existing grass. Scotts Turf Builder Rapid Grass Tall Fescue Mix grows green, lush grass, in just weeks! Grass seed germinates best when temperatures are between 60ÂF and 80ÂF and without danger of frost, usually in the Fall and Spring. To apply, rake the top layer of soil before applying with a Scotts spreader. For best results, water twice daily for at least 3 weeks. One 5.6 lb. bag covers 1,845 sq. ft. when overseeding an existing lawn, and 615 sq. ft. when growing a new lawn. Do not use weed control products until your lawn has been established (mowed at least 4 times). If you already applied weed control, please see those package directions on when to plant grass seed. Finally, be sure to apply Scotts Lawn Food products every 8 weeks throughout the season to help maintain your thick, green lawn.
