Turf Builder Triple Action Built for Seeding, 4.3 lbs. | Weed Preventer and Fertilizer for New Lawns, Covers 1,000 sq. ft.

I’ve been using Scotts Turf Builder Triple Action Built for Seeding on my new lawn, and I’m really impressed with how well it works. This product is a game-changer for anyone trying to establish a healthy, beautiful lawn from scratch. It combines three important functions into one seed, weed prevention, and fertilization, which is incredibly convenient. The application process was super easy. I used a spreader to cover my lawn, and it went down evenly with no issues. After a couple of weeks, I started to notice new grass growing in the bare spots, and the weeds that had been creeping in were effectively kept at bay. It’s great not having to worry about multiple products or treatments; this one does it all in one go. I’ve noticed that the grass is not only growing well but also looking greener and healthier. The fertilizer in the product gives it a solid boost, promoting strong root development and helping the grass thrive. This is especially important for new lawns, and I can already see the difference. As for the size, the 17.2 lbs bag covered the recommended 4,000 sq. ft., which was perfect for my yard. It’s worth noting that you do need to water the lawn after applying this, and I’ve been consistent with that to get the best results. The product didn’t cause any burn spots, which can sometimes happen with fertilizers, so that’s a relief. The only thing to keep in mind is that it’s important to apply it at the right time of year, preferably in the early spring or fall, so you get the most out of the weed prevention aspect. I’ve used other fertilizers before, but this one seems to be more comprehensive and effective in promoting new growth and keeping weeds away. Overall, I’d highly recommend this product if you’re working on a new lawn or even just want to improve your existing one. It saves time and effort by combining three essential lawn care tasks into one step, and the results speak for themselves.

First picture is day one (11-1-2024) when I planted grass seeds and put down the fertilizer built for seeds. All dirt, no growth as you can see. Second picture is about 5-6 days later. The grass is starting to sprout. Third picture is today (11-9-24) only 8 days after planting the seeds and the grass is growing very well. I would say 80% of the growth is from the fertilizer. Another 10% of growth is from putting seed cover (top soil) on top of the seeds to: 1. keep the birds from eating the seeds; 2. helps the seeds grow a little faster; 3. helps the soil maintain moisture. The last 10% of growth is from watering the grass (3) times per day. The seeds need to be maintained in moisture for as long as possible so they can sprout. I planted the same seeds in my front yard, but I didn't use the fertilizer made for seeds, and I think it took a while longer to grow. I will definitely buy more of the Scotts triple action built for seeds fertilizer whenever I need to start another grass project from scratch. I'm very happy with the results. One thing: don't put down too much fertilizer or it will burn the grass. I went back and put down more fertilizer where I thought it needed more, and in those spots the grass is turning white instead of green. It's still growing, but not as fast as in the other areas. Great product!!!

I don't know how well this actually helped the seeds grow, but it did do a decent job at weed control. The weeds weren't affected right away, but after about a week I noticed the weeds turning white and I have fewer Bitterroot (bitterdock root?) it also killed some of the blackberry vines, clover wasn't effected (which I was fine with, because bees like the clover).

Seeded the lawn in Indiana early Spring 2026 after aeration, correcting bad spots from a hot summer and little rain. Scotts Triple Action built for new seed worked great. I plan on using this product every Spring going forward. Best of all it not only stopped weeds in freshly seeded lawn, it help what previous grew in past years. I highly recommend this product.

Before I bought this, I researched a fertilizer and weed preventer product that would feed the lawn and prevent new weed growth -- but would not prevent my new grass overseed (Kentucky 31) from sprouting/growing. This is the product AI suggested. Although I have a strong amount of turf, I decided to 'winter-seed' because I did a major dethatch this fall. Today (after a soaking rain), I applied Triple Action according to instructions (4.5 on my Scotts spreader). The product is not made up of large granules like other fertilizers. It has very small granules that dispense and broadcast easily and evenly. The bag says it covers 4,000 sq ft which I found to be precise. I'm including a 'before' picture of one small area of my lawn. I intend to return to this posting late this Spring to present the results. It's now just several weeks later -- mid-March. Here's the same area of my lawn. It's incredibly thick and weed-free.

Since Amazon offers non other forum for providing feedback to them regarding their shipment vs the product, I am leaving the review here. Fertilizer box and bag were pierced, leaving granules everywhere once opened. Product itself is fine, but very disappointed in the handling of the packaging.

Works great. We bought because we had just re-seeded our lawn and were disappointed to find out the traditional weed and feed may affect our seeds. We purchased this bag to avoid killing the new grass seed and it worked great! The grass grew twice as fast as the areas we didn’t place this and was a dark luscious green color. Bags are small

My son uses this whenever he cuts the grass. We haven’t really seen any real change so we’re just gonna have to wait. This area is all dead grass all year around anyway. As you can see everyone’s yard here or did until winter then everything is green
