Description
Build your lawn with Scotts Turf Builder Thick'R Lawn Sun & Shade. With this combination grass seed, fertilizer, and soil improver, you can get up to a 50% thicker lawn subject to proper care (results may vary based on the condition of your lawn). This 3-in-1 solution for thin, weak lawns helps turn your grass into thicker, greener turf with stronger roots in one easy application. Use this product to overseed your lawn once in the late spring and once in the late summer or early fall. Apply in three easy steps: 1) Prep your lawn by mowing to 2 inches or at the lowest mower setting, then rake to loosen the top layer of soil and remove dead grass and debris. 2) Use a Scotts spreader to apply (use the recommended settings on the label). 3) Water daily or as needed to keep the soil surface moist for 2 weeks until seeds germinate, then water regularly to maintain seedling growth. One 40 lb. Bag of Scotts Turf Builder Thick'R Lawn Sun & Shade covers 4,000 sq. Ft.

Just a quick note before getting into this. The images attached were taken ~ 7 weeks apart. Mid spring to end of spring. Just before prep and treatment to fully developed. During these 7 weeks normally the yard would somewhat green... but its always been a leafy, crab grassy, weedy mess that would die off and leave nothing but moss. The lawn was always good from far but far from good. So, to be blunt, the property was a WRECK since we moved in... but the ‘before’ pictures make it seem much worst than it usually looks at this time. Now to the review. Our yard is 15kish sq ft of sun/shade mix. I ordered 5-40lb bags to really cover it. We dethatched and also scarified the lawn before tossing away all the moss and dead debris. Basically leaving 70% soil left over. I applied the scotts 3-in-1 Thick’r immediately after prep and followed the directions to a T. Watered twice a day. Never too much or too little. Used starter fertilizer to get things going. Then sat back and waited. Watered. Waited. And repeat. First, the negative - it took almost 3 weeks to receive the product. But with everything going on (covid-19) I’ll let this slide. It also took twice as long, if not longer, to start growing in, than stated. The bag, and reviews, state 7-10 up to 14 days. After 21 with next to no growth I nearly gave up watering and called the pro’s. But after around 30 days it really started filling in. By week 5 it was full. Not sure what was stopping it, maybe weather or sun, but something jump started the growth and it took right off. Since then it’s continued to fill in. At week 6 we mowed for the first time and it’s only grown thicker since. I am extremely happy with where we are today on this lawn rehab and it’s completely thanks to this product. We had similarly tried to treat the property in the past with just seed and fertilizer from another brand and it was a complete waste of money. Nothing grew. Without hesitation I would recommend this product to anyone living in the area. Already have to several neighbors who have commented on the property.

This works..I mixed in more grass seed and used twice on lawn in September spaced 3 weeks apart. With low fertilizer content I figured I would go for it. In NJ we have had a ton of rain and it was mild thru early November and I see a big difference in my lawn. I manually dethatched, applied with extra seed, watered daily for the first 2 weeks then let mother nature take over. Second application I did before predicted rain and 3 months later, even with the cold weather, it looks great. I imagine some will die due to freeze, but it is better than overseeding alone, and the grass has a nice deep green color. I mixed with kentucky blue on my front lawn since there is very little foot traffic, and in backyard with my 80lb dog, I used heat tolerant blue, perennial rye and some kentucky blue mixed in. This product eventually filled in damage from my dog, but still recommend the lawn repair for large areas of dead or no grass, and recommend adding seed to that product too if quicker germination is needed. I will buy again and use in the spring a month after applying the weed prevention fertilizer.

Standard for all my reviews: When reviewing products, I always remain objective and honest about the product or service. I always review with information that I feel others would like to know about the product as I always assume what I'm writing will influence for or against the purchase. I always try to go above and beyond surface characteristics and input into quality, value and application. Most importantly, I will always end the review with an answer as to whether I'd purchase the product again which I believe is the most critical question pertaining to the item. To manufacturers: Want me to review your items, just let me know! I read a lot of reviews from people frustrated with their grass seed. Not all seed or products are the same in how they are planted, ongoing care, etc. Some include built in mulch, fertilizers, etc. while others are just seed. This 3 in 1 contains the seed, fertilizer and a soil improver. Most contain the first two items and I'm a bit skeptical about the "soil improver" though they claim in creates a healthier root system. In my history and experience, while that may be true, most other variables are over-arching before things like a soil improver, meaning that your native soil, depth of soil, drainage and watering habits will determine how well your grass grows and looks. But alas, it has all three for your seeding enjoyment. But to all of you who struggle with using seed, you MUST prepare properly. If you expect to simply walk around with a spreader and end up with a lawn like they show in the pictures, or successfully have a thick patch where a bald spot was, it's likely not going to happen. Between the rain washing seed away, sun baking the seed and the birds thanking you for putting their food on the ground instead of in a feeder where it's so crowded, your results may not be what you expect. Clear the area, if you can, of any debris, dead grass (Thatch), etc. Then be sure to break up or loosen the ground/soil with a garden tool or the like to a depth of an inch or so. Then you can apply your seed. For best results, then cover with a peat, soil, mulch or something to get the seed out of view and away from the sun. Lightly water to keep moist for the next 10-14 days to allow the seeds to germinate and take root. As for this product, I've had success and no success on multiple spots but generally the success has been good. I don't seem to get quite the germination I have from other products in the past but good enough that I can leave it a 4-star rating. I just focus far more on soil prep to make sure I have a good foundation. I will say that this bag will last longer as it doesn't contain the mulch which also functions like the top layer and fertilizer, it only contains the seed, fertilizer and soil improver. So it gets my "good not great" rating meaning that I would purchase it again but would use another product that I've found more effective. It's solid, not great.

I like a decent lawn but am not going to go crazy seeding, weeding, liming, etc...and my lawn reflects that. My mantra is usually "if it's green, it's grass" and I cut it. As a result, the lawn looks okay but can often be thin, sometimes kind of brittle to walk upon, and only light green in color. There are some things I will try occasionally in the spring to improve its look but not much...and I only do it then. The lawn is pretty much on its own after that. Have neither the time nor the inclination to care for the lawn continuously throughout the season. That being said, I tried the turf builder this spring in the front yard and on the right side of the house, areas which can be thin, weedy and even threadbare. I did put down a little extra grass seed as well, and I mean a little, and watered with a sprinkler every other day for about 7-10 days. Well, I am so pleased with the results that I am writing this review and have told others. This turf builder has made a noticeable difference in the look and feel of my lawn. There are fewer weeds, it is more lush, more green and it looks healthier. In fact, I can honestly say it looks the best it has ever looked since I moved to this house 15 years ago. A telltale sign of the turf builder's effectiveness is the untreated part of my lawn. I can actually see the difference between the treated and untreated areas. The treated area is noticeably darker green and fuller, with the grass growing taller. I am just sorry I did not do the whole lawn. It is on my calendar to do that next spring. As another reviewer has written, don't give up on this too quickly. You need to give it about 2-3 weeks and water it a bit in the beginning. I do hope anyone who uses this product has as much success with it as I have had, and with such relatively little effort. ADDENDUM - 7/23/2019: During the Fall of 2018 I decided to use this on the entire lawn. Bought four 40 lb. bags and mixed in some more grass seed. Laid it all down in late September hoping for the best in the Spring. Well, I was not disappointed. At first, it did not seem to make much difference. As it got into May and June, though, I noticed an overall improvement even in very shaded areas which had previously had little grass and sometimes moss. With such encouragement from my lawn, I will probably do the same this Fall, likely adding a couple more bags. One thing, I did water much of it for about an hour a day for a week. I have a half acre (about 75% lawn, the rest trees and large shrubs). It was kind of a pain to keep moving the sprinklers, and my water bill shot up for one cycle, but I felt the hydration was necessary and worth it.

I was honestly surprised by how well this worked. My lawn had several thin, patchy areas that never seemed to fill in no matter what I tried. After applying Scotts Turf Builder Thick'R Lawn and following the watering instructions, I started noticing new growth within a 3-4 weeks. The grass came in thicker, greener, and much more even than before. What I like most is that it's an all-in-one product, so I didn't have to buy separate seed, fertilizer, and soil improver. It made the whole process simple and saved me time. The coverage was also very close to what was advertised for my yard size. A couple of weeks later, my lawn looks healthier and fuller, and one of my neighbor have asked what I've been using. If you're dealing with thin grass and want an easy solution, I highly recommend giving this product a try. Definitely worth the money!

I purchased this hoping it would fill in some bare spots and areas that were thin. I had first dethatched my lawn and then scarified it as well preparing the soil as best I could for the seed. I had delivered from a landscaping company their best lawn soil mixture. I purchased a lawn leveling rake so I could level the lawn from some low spots. I went ahead planted the seed with the fresh soil and leveled the lawn. Kept it watered and in over a month now zero nothing not a blade of grass. I had only used 1/2 of the bag because the area I was covering was around 1000 sq feet and the bag says up to 4000 sq feet so I was planning on reseeding in the fall. It’s laughable to think 4.8 lbs of grass seed will cover 4000 sq feet of lawn when on average they recommend 4-7 lbs per 1000 sq feet for over seeding. So I wasn’t even using half of the recommender area and half the bag so I was well covered. So after a couple weeks I decided I would try a old trick of putting grass seed in my wheelbarrow and grow it under optimum conditions. I went and purchased SCOTTS LAWN SOIL FOR SEED. Keep it in the family I thought. Can’t blame the soil If it’s their own I went and mixed up a co side table amount of the product with the soil In my wheelbarrow. I watered it and covered it and put in my shed. I monitored it every day and then I decided to bring it out in the sun when the temps went up. It was easy to keep it moist. I have a raised bed vegetable garden a Hosta garden so I am an avid gardener. I love plants and gardening. I have Window boxes I grow flowers in every year so I’m not some rookie who doesn’t understand how grass grows. Grass needs warmth, moisture and direct contact with soil. That’s it the seed will do the rest as it has all it needs to sprout. Keep it moist warm and in contact with soil. Why the wheelbarrow is a great place to jump start seeds. It’s been 18 days and not a single blade of grass. This seems almost impossible unless this bad had no grass seed in it at all. Idk but I looked on the bag and here is what’s included. 3.68% Alloy Perennial Ryegrass 3.62% Vision Perennial Ryegrass 1.85% Bolster Chewings Fescue 1.75% Boreal Creeping Fescue .61% Starr Kentucky Bluegrass .61% Dauntless Kentucky Bluegrass Other ingredients: 87.81% Inert Matter .06% Other Crop Seed .01% Weed Seed This comes to 12.1% Seed 4.8lbs 87.88% Inert Matter 35.15 lbs Total 40lbs So they expect us to believe 4.8 lbs of grass seed can fill in your lawn of 4000 sq feet? And if I called and asked them how much grass seed would I need for 1000sq feet I would be told 4-7 lbs to overseed it. So in this bag they put in little seed and tell you it covers 4000sq feet but if you buy straight grass seed you need as much as 7 lbs for 1000 sq feet? Something isn’t right. So I am done with Scott’s grass seed. There so called guarantee. Guaranteed you will look to another company for your lawn care products after using ours.

This stuff is absolute magic for a patchy lawn! When I moved into my place last year, the yard was full of big, burnt-out patches. I used this to repair the damage after a hard winter, and waking up this spring, the transformation is incredible. My grass is growing in perfectly with zero burn spots in sight. I just bought another bag to give a few more areas some extra love, and you can already see exactly where I dropped the seed. The new growth is 'angry' green—so healthy, rich, and thick. I’ve used this product many times now, and the results are always amazing. Pro Tip: If you want these results, you have to make sure you water it! If you put in the work, this product will do wonders for your lawn. I’d suggest it to anyone looking to fix their yard.
