Scotts Turf Builder Lawn Food

The standard bearer. If you only buy one fertilizer and you do not want to think too hard about it, this is the one. It is designed for any grass type and can be applied in spring, summer, or fall. That flexibility makes it the true jack-of-all-trades in this lineup.

What stands out is its focus on root development. The label talks about building strong, deep roots, which is what you actually need for a lawn that survives summer heat and winter cold. It feeds the grass to help it fend off future problems rather than just giving a quick green flush. It also does not contain pesticides, so you are not adding unnecessary chemicals to your yard.

The trade-off is that it is a basic formula. It does not have extra iron for that deep emerald color, nor does it address weeds or insects. You will need to handle those issues separately. Also, because it is a synthetic fertilizer, it can burn the lawn if you apply it too heavily or skip watering it in.

• Safe for all grass types
• Apply to wet or dry lawn
• Builds deep roots for drought resistance
• Pesticide-free formula
• Coverage: 12.5 lb. bag

Best for: The homeowner who wants a single, reliable granular feed for general lawn health without any extra bells and whistles.

Scotts Turf Builder SummerGuard

Summer is brutal on lawns. Heat, drought, and insects all attack at once. This product is purpose-built for that specific window. It combines a high-nitrogen feed with an insect killer, so you can tackle two problems with one pass of the spreader.

Its main strength is convenience. You treat for grubs and other listed pests while feeding the grass to help it withstand heat stress. The formula is designed to not burn the lawn, which is a common fear when fertilizing in hot weather. It also encourages deeper roots, which helps the grass access water further down in the soil.

This is not a general-purpose fertilizer. You should only use it in the summer months. Also, the insect control component is a pesticide, so it is not the best choice if you are trying to maintain an organic lawn. You need to check the label to see which specific insects it targets.

• Feeds and protects against heat stress
• Kills and controls listed insects
• Safe for lawns when used as directed
• Helps prevent runoff and soil erosion
• Coverage: 13.35 lb. bag covers 5,000 sq. ft.

Best for: Homeowners battling summer pests who want a dual-action product to simplify their lawn care routine.

Scotts Natural Lawn Food

For those who prefer to avoid synthetic chemicals, this is the standout. It is OMRI listed, which means it meets strict organic standards. You can use it around kids and pets, and it is safe to walk on immediately after application. That peace of mind is a big deal for families.

It builds a thick, green lawn using natural ingredients. It works on any grass type and can be applied any season. The granular format is easy to spread with a standard drop or rotary spreader. You can apply it up to four times per year, which gives you flexibility to adjust to your lawn’s needs.

The downside is that natural fertilizers generally release nutrients slower than synthetic ones. Do not expect a dramatic green-up overnight. It takes a few weeks to see visible results. Also, the bag is heavier (29.1 lbs.) for the same coverage as the synthetic options, because organic materials contain more filler.

• OMRI listed for organic use
• Safe for kids and pets after application
• Can be applied in any season
• Works on all grass types
• Coverage: 29.1 lb. bag covers 4,000 sq. ft.

Best for: Eco-conscious homeowners who want a safe, natural feed for their lawn without sacrificing convenience.

Scotts Turf Builder WinterGuard

Fall is the most important time to fertilize your lawn. The grass is storing energy for winter and preparing for a strong start in spring. This WinterGuard formula is designed specifically for that job. It helps the lawn recover from summer damage and builds strong roots to survive the cold.

This product shines in its timing. It delivers a specific nutrient blend that prioritizes root growth over leafy top growth. That means your lawn stores food in the roots, which leads to a thicker, healthier lawn when things warm up. It works on any grass type and can be applied to a wet or dry lawn.

It is not a product you should use in the spring or summer. Using a high-phosphorus fall formula at the wrong time can actually harm your lawn. This is a specialized tool for a specific season, so you will need a separate fertilizer for the rest of the year.

• Builds strong roots for winter survival
• Helps recovery from summer heat and activity
• Formulated for fall application
• Works on any grass type
• Coverage: 10 lb. bag covers 4,000 sq. ft.

Best for: Homeowners who want to give their lawn a strong head start for next spring by focusing on root health in the fall.

Farmer’s Secret Lawn Booster

This one breaks the mold. It is a liquid concentrate, not a granular product. That makes it a great option for small lawns or for spot-treating problem areas. It is also super concentrated, so a little goes a long way. The manufacturer recommends 8-12 ounces per 1,000 square feet monthly.

Its formula is well-rounded. It contains the primary macronutrients (nitrogen, phosphorus, potassium), plus key micronutrients and humics. Humics are important because they improve the soil’s ability to hold nutrients and water. This is a product that feeds the soil, not just the grass.

The main drawback is the application method. You will need a hose-end sprayer to apply it evenly over a large area. That can be more time-consuming than pushing a broadcast spreader. Also, because it is a liquid, the results are quick but may not last as long as a slow-release granular product.

• Liquid concentrate for easy mixing
• Contains micronutrients and humics
• Use on all lawn and turf types
• Super concentrated formula
• Made in Kentucky

Best for: Gardeners with small to medium lawns who want a fast-acting liquid feed that also improves soil health.

How We Chose These Products

We started with the basics. Every product had to be a genuine all-around fertilizer suitable for most grass types. We excluded specialty blends designed only for specific grass species like centipede or zoysia, as those are not universal solutions.

From there, we evaluated nutrient content, application flexibility, and the specific problems each product solves. We looked at whether the formula was synthetic or natural, granular or liquid, and how that affects real-world use. We also considered coverage area and how often you need to apply the product. The final list represents a range of options to fit different lawn care philosophies and budgets.

Buying Guide: What Really Matters

Before you buy anything, you need to know your grass type. Cool-season grasses like fescue and Kentucky bluegrass have different needs than warm-season grasses like Bermuda and Zoysia. While products like Scotts Turf Builder work on all types, the timing of application matters. Cool-season grass gets its biggest feeding in the fall, while warm-season grass prefers summer feeding.

The next step is a soil test. This is a step many people skip, but it is the only way to know what your lawn actually needs. A soil test will tell you your pH level and whether you are deficient in phosphorus or potassium. If your soil already has enough phosphorus, you should choose a fertilizer with a zero in the middle (like a 25-0-0) to avoid runoff. Many municipalities now restrict phosphorus use because it pollutes local waterways.

Finally, look at the release mechanism. Slow-release nitrogen feeds your lawn steadily over 6-8 weeks. It is more forgiving and less likely to burn. Quick-release nitrogen gives a fast green-up but can cause a growth spurt that requires more frequent mowing. For a low-maintenance approach, look for a product that contains some slow-release nitrogen.

Our Top Recommendation

For the vast majority of homeowners, the best lawn fertilizer is the Scotts Turf Builder Lawn Food. It is versatile, easy to use, and effective on any grass type. You can apply it in spring, summer, or fall, which means you do not have to overthink your schedule. It builds a solid foundation for a healthy lawn.

If you prefer an organic approach, the Scotts Natural Lawn Food is the runner-up. It is safe for kids and pets and still delivers good results, just at a slower pace. For those dealing with fall preparation, the WinterGuard is a smart seasonal choice. And if you want a liquid option for a small yard, the Farmer’s Secret is worth checking the current price on Amazon.

Frequently Asked Questions

What does the NPK ratio on the bag mean?
NPK stands for Nitrogen, Phosphorus, and Potassium. The numbers represent the percentage of each nutrient by weight. Nitrogen (N) promotes leafy green growth. Phosphorus (P) helps with root development. Potassium (K) improves overall plant health and disease resistance. A balanced fertilizer like 10-10-10 has equal parts of each.

Can I use the same fertilizer for my whole lawn?
Yes, if you have a uniform grass type. If your lawn has a mix of cool-season and warm-season grasses, a general-purpose feed like Scotts Turf Builder is your safest bet. It is formulated to work with any grass type, so you do not need to worry about damaging one section while feeding another.

How do I know if my lawn needs phosphorus?
You should only know this by doing a soil test. Most county extension offices offer this service for a small fee. If your soil test shows adequate phosphorus levels, choose a fertilizer with a zero in the middle, like a 25-0-0. This prevents excess phosphorus from running off into storm drains and polluting local water sources.

Is it better to use a liquid or granular fertilizer?
Granular fertilizers are easier to apply evenly over a large area and often provide slow-release nutrients. Liquid fertilizers act faster, but they require more frequent applications. If you have a small lawn, a liquid like the Farmer’s Secret is convenient. For a large lawn, granular is usually more practical. You can find a good spreader for granular options in our lawn thickening guide.

Choosing the right fertilizer is about matching the product to your lawn’s specific needs. Start with a soil test, know your grass type, and pick a product from the list above that fits your schedule and philosophy. Your lawn will thank you.
