Scotts Turf Builder is the most popular lawn fertilizer in America. Walk into any Home Depot or Lowe’s and the Scotts bags take up half the aisle. But is it actually good? Or just good marketing?
I have used Scotts Turf Builder for five years on my lawn. I have tried the regular Lawn Food, the WinterGuard, the Green Max, and the Triple Action. Here is my honest review based on real results.
What Is Scotts Turf Builder?
Scotts Turf Builder is a synthetic granular fertilizer made for home lawns. The standard formula is 32-0-4. That means 32% nitrogen, zero phosphorus, and 4% potassium.
Scotts uses something called “All-in-One Particle” technology. Each granule contains the same amount of nutrients. Some cheap fertilizers mix different granules for different nutrients. Scotts puts everything in one granule. That gives more even coverage.
About 50% of the nitrogen is slow-release. The other 50% is fast-release. This gives you a quick green-up that lasts several weeks.
Scotts Turf Builder Products I Have Tested
1. Scotts Turf Builder Lawn Food (32-0-4)
This is the standard blue bag. It covers 5,000 square feet. I use this in late spring and early summer. Results show up in 5 to 7 days. The green is deep and even.
One bag costs about $25 on
. At 5,000 square feet of coverage, that is $5 per 1,000 square feet. Fair price for the results.
The biggest downside: you must water it in. If you forget and let it sit on dry grass for days, you will get burn spots. I learned that the hard way.
2. Scotts WinterGuard Fall Lawn Food (32-0-10)
The orange bag. Higher potassium than the standard formula for winter hardiness. I apply this in September and again in late October.
Results are less visible than the spring formula because grass grows slower in fall. But the real payoff comes in spring. My lawn greens up two weeks faster than my neighbors who skip fall fertilizer.
Same price. Same coverage. Worth every penny for the spring head start.
3. Scotts Green Max Lawn Food (27-0-2)
Green Max has 5.17% iron in addition to the NPK. Iron makes grass turn a darker, richer green. I use this before parties or holidays when I want the lawn to look extra good.
The green is noticeably deeper than regular Turf Builder. But it fades faster. The iron effect lasts about 3 weeks. The nitrogen lasts 6 weeks. Good for a quick beauty boost.
4. Scotts Turf Builder Triple Action (28-0-3)
This is fertilizer plus weed killer plus crabgrass preventer in one bag. The weed killer is 2,4-D and mecoprop. It kills dandelions, clover, and other broadleaf weeds.
I use this in early spring when weeds are just starting. It works well if you apply it to wet grass. The weed killer needs to stick to the leaves. Do not water for 24 hours after applying. Timing is tricky. Apply too early and the pre-emergent washes out. Apply too late and weeds are already growing.
Triple Action costs more at about $35 per bag. But it replaces three separate products. Good value if you have weed problems.

Scotts vs Store Brands: Is Scotts Worth the Extra Cost?
Scotts costs about $5 more per bag than store brands like Ace Hardware or Walmart Expert Gardener. Is it worth it?
In my testing, yes. The All-in-One Particle is not just marketing. Store brand fertilizers use blended granules. Some granules are pure nitrogen. Others are filler. This creates uneven coverage. Scotts granules are uniform. Every granule feeds equally.
Store brands also use more fast-release nitrogen. That means faster green-up but shorter duration and higher burn risk. Scotts slow-release nitrogen feeds for about 6 weeks. Store brands last 3 to 4 weeks.
If you are on a tight budget, store brands work. But Scotts gives better results with less risk of stripes or burns.
Frequently Asked Questions
How long does Scotts Turf Builder take to work?
You will see visible greening in 5 to 7 days after applying Scotts Turf Builder. Full results take 2 to 3 weeks. The feeding effect lasts about 6 weeks.
Is Scotts Turf Builder safe for pets?
Scotts Turf Builder is safe for pets after you water it in and the lawn dries. Keep pets off the lawn for 24 hours after application, or until after you water and the grass is dry. The granules themselves can cause stomach upset if eaten.
Can I apply Scotts Turf Builder in summer?
Yes, but be careful. Synthetic fertilizer can burn grass when temperatures are above 85 degrees. Apply at half the recommended rate during hot summer months. Or switch to an organic fertilizer like Milorganite that has zero burn risk.
How often can I apply Scotts Turf Builder?
Scotts recommends applying every 6 to 8 weeks during the growing season. That is about 4 applications per year for cool-season grasses. Follow the bag instructions. Applying more often or at higher rates will burn your lawn.
