About This Product
Most lawns have sunny areas and a shady spot. Scotts Turf Builder Grass Seed Sun & Shade Mix thrives in both. This 3-in-1 combination of seed, fertilizer, and soil improver features Root-Building Nutrition to help establish deep roots for thick, green turf. The seed is treated with mefenoxam, a fungicide that helps protect seedlings from damping-off, a disease favored by the damp soil new seed needs. Plant it in spring or fall, when air temperatures are between 60°F and 80°F, to start a new lawn or overseed an existing one. At Scotts, we know that freshness matters, and we go to great lengths to bring you the freshest seed available.

How To Use
New Lawn
- Prep: Rake the area to loosen the top layer of soil (about 2 inches deep) and remove any dead grass or debris so the seed makes good contact with the soil.

- Water: Water daily or as needed to keep the soil surface moist, and keep it up for at least 3 weeks or until seedlings reach 2 inches tall.
Overseeding
- Mow: Mow your lawn at the lowest setting (about 2 inches) and bag the clippings.
- Rake: Rake to remove debris and dead grass and loosen the soil so the seed makes good contact with the soil.

Product Safety
- Keep out of reach of children.
- This seed has been treated with mefenoxam, a fungicide that helps protect grass seedlings from damping-off, a harmful disease caused by the water molds Pythium and Phytophthora. The frequent waterings and damp soil conditions that new seedlings need also encourages water mold development. The fungicide coating helps improve seedling survival.
- Do not use for food, feed, or oil purposes. Store away from feeds and foodstuffs.
- Store in a cool, dry place, out of reach of children. After opening, plant within the season.
- Do not apply near water, storm drains, or drainage ditches, and do not apply if heavy rain is expected.
- Apply only to your lawn. Sweep any product that lands on your driveway, sidewalk, or street back onto your lawn.

These products are Excellent! Fantastic Results!
Last fall, we resurfaced our entire front lawn first by using Round up to kill everything & removed debris & dead roots with sharp thatch rake, scraping/regrading low areas, seeded, and fertilized with Scotts Triple Action. (The lawn was mostly weeds & dead grass from drought) . The grass came in beautifully, as weeds were effectively controlled weeds (some crabgrass was stubborn). This spring, we used this fertilizer first as a preventative before temperatures were suitable for seeding. A few weeks later, after removing large dying weeds, too big to leave in, we applied the 3-in-One fertilizer a SECOND time and over-seeded with the Scott’s special PA State Blend covering any bare patches. Watering daily, along with some April showers, the grass has never looked better! The best part? The grass is green on OUR side!😆☺️ I love that this fertilizer is safe for seeding AND does a great job killing those pesky weeds, ESPECIALLY nutsedge, which is very difficult to eradicate. Thank you, Scotts! Tip: If directions are followed carefully, the outcome is well worth the effort!

Smartest Decision for my yard every
I decided to save money and stop paying fertilizer companies to do a nominal job of caring for my yard. I am so glad I switched. I am saving money and my lawn is looking amazing.

Beautiful backyard - waiting patiently for front
Mid summer I planted a new lawn in back of house and it came in thick and lush with no problems in about 10-15 days.
Early fall I planted the front area and I’m still waiting for one blade! I followed the same procedure I used on back. The only difference was newly purchased bags of seed. Is it possible the seed was compromised? I am using sun & shade.
