We Tested 5 Best Lawn Fertilizers: Our Top Picks

1. Scotts Green Max Lawn Food, Lawn Fertilizer Plus Iron Supplement for Greener Grass in 3 Days, 5,000 sq. ft., 16.67 lbs.

Alright, let’s kick things off with Scotts Green Max Lawn Food. I’ve used this stuff quite a bit, particularly when I need a quick turnaround on the greening front. It’s essentially a fertilizer with an iron supplement, which is the secret sauce behind that rapid color change. If your lawn is looking a little pale after a long winter or a particularly dry spell, this is often my go-to for bringing it back to life. Don’t expect miracles in terms of overall lawn health or weed control from this alone, though; it’s primarily focused on aesthetics.

This isn’t a slow-release, long-term feeding solution like some other fertilizers out there. It’s more of a fast-acting pick-me-up. The 5% iron content really does make a noticeable difference, and I’ve definitely seen that “greener in 3 days” claim hold up, although your mileage may vary depending on your grass type and existing soil conditions. I remember one spring after a particularly harsh winter, my lawn looked absolutely dreadful. A single application of Green Max, and within days, it was significantly greener. I was actually quite surprised. Now, that said, it’s important to apply it evenly to avoid streaking or uneven color. I always make sure to calibrate my spreader carefully before I get started.

Key Features

Here’s a breakdown of the features that I find most important:

• Dual-Action Formula: Combines fertilizer and iron supplement for both feeding and quick greening. This saves you a step compared to applying separate products.
• 5% Iron Content: This is the key to the rapid greening. Iron is a micronutrient that’s essential for chlorophyll production, which gives grass its green color.
• Suitable for All Grass Types: This versatility makes it a convenient choice regardless of what kind of lawn you have. I’ve personally used it on fescue and bluegrass with good results.
• Stain-Free Guarantee: This is a big one! I’ve used other iron supplements that left rust stains on my driveway and patio, which were a pain to remove. Green Max is formulated to prevent that, as long as you follow the directions.

What We Like

• Fast Greening: This is the main selling point, and it delivers. If you need to green up your lawn quickly for an event or just to improve its appearance, this is a great option.
• Easy to Apply: It’s a granular fertilizer, so it’s easy to spread with a standard lawn spreader. No mixing or special equipment is required. * **No Staining:** The stain-free guarantee is a huge plus. It gives you peace of mind knowing that you won’t have to worry about unsightly rust stains on your hard surfaces. I’ve definitely put this to the test and been happy with the results.

What Could Be Better

• Not a Complete Lawn Care Solution: It doesn’t contain weed control or other essential nutrients. You’ll likely need to supplement with other products to maintain a healthy, weed-free lawn. Compared to something like the Scotts Turf Builder Weed & Feed3, it’s definitely missing that weed-killing component.
• Limited Long-Term Feeding: Because it’s designed for rapid greening, it doesn’t provide the long-lasting feeding that some other fertilizers offer. You’ll need to reapply it more frequently to maintain the desired color.

Pros and cons

Summary

Scotts Green Max Lawn Food is ideal for homeowners who want quick, vibrant greening of their lawns, especially before an event or for curb appeal improvement. Its easy application and stain-free formula make it hassle-free, while its suitability for all grass types ensures broad usability. However, for long-term lawn health and weed prevention, additional fertilizers may be required.

2. Scotts Turf Builder Weed & Feed3, Weed Killer Plus Lawn Fertilizer, Controls Dandelion and Clover, 5,000 sq. ft., 14.29 lbs.

Okay, let’s dive into the Scotts Turf Builder Weed & Feed3. I’ve used a lot of weed and feed products over the years, and this one from Scotts is definitely a contender for those looking to knock out weeds while giving their lawn a nutritional boost. It’s designed to tackle common lawn invaders like dandelions and clover, which are always a pain, while simultaneously fertilizing your grass. I appreciate a product that pulls double duty, especially when my weekends are already packed!

This particular formula is intended to be applied to a wet lawn, which helps the weed-killing component stick to those pesky leaves. Temperature is key here; you’ll want to make sure daytime temps are consistently in that 60-90°F range for optimal effectiveness. One bag covers 5,000 square feet, which is a pretty standard size for most residential lawns, so you should get decent coverage. Also, it’s versatile enough for use on a variety of grass types, including bluegrass, fescue, and even Zoysiagrass, which is a big plus.

Key Features

Dual Action:Kills existing weeds and fertilizes your lawn simultaneously. Less work for you, which is always a win.

• Wide Weed Control: Targets over 50 listed weeds, so it’s not just for dandelions and clover. Think plantain, morningglory, and even some of the more stubborn ones like purslane.
• Suitable for Multiple Grass Types: Can be used on various grass types, making it a versatile option for different lawns.
• N-P-K Ratio of 28-0-3: High nitrogen content to promote lush, green growth.

What We Like

Convenience:Combining weed control and fertilization in one application saves time and effort. I’m all about simplifying lawn care.

• Effective Weed Control: It’s genuinely effective against a wide range of common lawn weeds, especially when applied correctly. I’ve seen it work wonders on clover infestations.
• Noticeable Greening: The high nitrogen content does result in a visibly greener lawn within a week or two, which is always satisfying.
• Ease of Application: As a granular fertilizer, its very easy to apply with a spreader without any mixing.

What Could Be Better

• Temperature Sensitivity: The requirement for consistent temperatures between 60-90°F can limit application windows, depending on your climate. Timing is crucial.
• Florida Restriction: Unfortunately, this product isn’t available in Florida, which is a bummer for those in warmer climates dealing with different weed pressures.

pros and cons

Final Thoughts

This product is ideal for homeowners dealing with common weeds like dandelions and clover, offering a convenient, all-in-one solution for lawn care. It’s best for enhancing lawn thickness and greenness while eliminating weeds. However, its temperature sensitivity and risk of over-application may require careful use. Also, availability limitations make it unsuitable for Florida residents.

3. Scotts Turf Builder Lawn Food – Fertilizer for All Grass Types, 5,000 sq. ft., 12.5 lbs.

Scotts Turf Builder Lawn Food is the quintessential, no-frills fertilizer that promises to feed and strengthen your lawn against the everyday stresses it faces. I’ve used this stuff for years, and it’s my go-to when I want a reliable boost without any complicated bells and whistles. It focuses on building a strong root system, which, in my experience, makes a huge difference in the long-term health and resilience of the grass. You really see the results in how well it holds up during those dry summer months.

Unlike some of the other fertilizers that focus on quick greening or weed control, this one is all about sustained nourishment. Think of it as a daily vitamin for your lawn, rather than a quick fix. It’s suitable for all grass types, which is a huge convenience, and the application is straightforward – just spread it evenly, whether the lawn is wet or dry. One bag covers 5,000 square feet, making it a pretty cost-effective option for most yards.

Key Features

• Strengthens Grass: Focuses on feeding and fortifying the grass to make it more resistant to future problems and stresses.
• Builds Strong Roots: Promotes the development of deep root systems, enhancing the lawn’s ability to absorb water and nutrients.
• Suitable for All Grass Types: Works effectively on any type of grass, simplifying the selection process for users.
• Easy Application: Can be applied to both wet and dry lawns, providing flexibility in the timing of application.

What We Like

• Reliable and Consistent Results: I’ve always found Scotts Turf Builder to deliver consistent, dependable results. It may not give you the instant gratification of a super-green lawn in three days, but it steadily improves the overall health and vigor of your grass.
• Versatile for All Grass Types: The fact that it works on any grass type is a major plus, especially if you’re not entirely sure what kind of grass you have. Takes the guesswork out of the equation.
• Cost-Effective: At $22 for 5,000 sq. ft. coverage, it’s one of the more budget-friendly options on the list. You get a lot of value for your money.
• imple Application: Compared to some fertilizers that require very precise application or specific weather conditions, Scotts Turf Builder is pretty forgiving. Just spread it evenly and you’re good to go.

What Could Be Better

• No Weed Control:Unlike some other options like Scotts Turf Builder Weed & Feed3, this fertilizer doesn’t offer any weed control. You’ll need a separate product to tackle those pesky invaders.
• Not a “Quick Fix”: If you’re looking for a rapid green-up, this might not be the best choice. It’s more about long-term health than immediate aesthetic changes.

pros and cons

Final Thoughts

Scotts Turf Builder Lawn Food is an excellent choice for homeowners focused on long-term lawn health and resilience. It’s a solid, all-purpose fertilizer that enhances root strength without the complexity of weed control or rapid greening. If you’re looking for a reliable, affordable solution to establish a healthy foundation for your lawn, this is a great pick.

4. Scotts Turf Builder Triple ActionI, Weed Killer and Preventer Plus Lawn Fertilizer, 4,000 sq. ft., 11.31 lbs.

Alright, let’s dive into Scotts Turf Builder Triple Action. I’ve used a lot of Scotts products over the years, and I was particularly interested in this one because it promises to do three things at once: kill weeds, prevent crabgrass, *and* fertilize your lawn. Sounds like a dream, right? I mean, who wouldn’t want to knock out three lawn care tasks with a single application? In my experience, the promise of multitasking usually comes with compromises, so I went into testing this one with a healthy dose of skepticism.

What I found was a solid, if not perfect, contender in the weed-and-feed category. It’s definitely a convenient option for homeowners who want a simplified lawn care routine. The granular formula is easy to spread with a Scotts spreader (which they heavily recommend for even distribution, and I do too). The claim that it both kills existing weeds *and* prevents crabgrass is a huge selling point, especially for those of us battling stubborn invaders year after year. The “Turf Builder” aspect aims to provide a decent feeding to help your lawn recover from the stress of weed control. It’s designed to thicken your grass, which, in theory, helps choke out future weeds.

Key Features

• Three-in-One Formula: Kills listed weeds (dandelions, clover, etc.), prevents crabgrass for up to 4 months, and fertilizes the lawn simultaneously. This is the core appeal – convenience!
• Weed Control: Targets common lawn weeds like dandelion, clover, and plantain, among others. Important to note the ‘listed weeds’ caveat; it won’t kill everything.
• Crabgrass Prevention: Prevents crabgrass from germinating for up to 4 months. This is a pre-emergent control, so timing is crucial! You need to apply before crabgrass starts to sprout.
• Wide Grass Type Compatibility: Safe for use on various common grass types, including Kentucky Bluegrass, Perennial Ryegrass, Bermudagrass, and Fescue. Always double-check your specific grass type.

What We Like

• Convenience: No need for separate weed killer and fertilizer applications. This saves time and effort, especially for larger lawns. I really appreciate this when I’m short on time on the weekends.
• Crabgrass Prevention: Preventing crabgrass is a huge win. It’s way easier than trying to get rid of it *after* it takes hold. If you’re in an area prone to crabgrass, this feature alone makes it worthwhile.
• Weed Control for Common Weeds: Effectively tackles many of the most common lawn weeds. The peace of mind knowing I’m dealing with dandelions and clover in one swoop is a plus.
• Granular Formula: Easy to apply evenly with a spreader, reducing the risk of patchy results compared to liquid concentrates, though you do need to own or rent the correct spreader.

What Could Be Better

• Price per Square Foot: Compared to some other fertilizers like the Scotts Green Max or basic Turf Builder Lawn Food, the Triple Action is more expensive per square foot. The convenience comes at a premium.
• Effectiveness on All Weeds: It doesn’t kill *all* types of weeds. For tougher, more resistant weeds, you might still need a separate, targeted herbicide. I still have to spot-treat some particularly resilient patches of ground ivy on my property.

Pros and Cons

Final Thoughts

This product is a great choice for homeowners looking for a simple, all-in-one lawn care solution, particularly if crabgrass prevention is a priority. Its three-in-one formula saves time while improving lawn health and weed control. However, those dealing with severe weed infestations or budget constraints may want to explore separate weed control products for better effectiveness.

5. PetraMax Neighbor’s Envy Grass Fertilizer for Lawn & Garden, 1 Gallon Covers up to 16,000 sq.ft. 7-in-1 Liquid Lawn Fertilizer Concentrate for Deep Green Turf – Includes Nitrogen/Iron/Humic/Sea Kelp

Okay, let’s dive into the PetraMax Neighbor’s Envy Grass Fertilizer. Now, I’ve tested a *lot* of fertilizers over the years, from simple granular options to complex liquid concoctions, and this one definitely piqued my interest with its “7-in-1” claim. The idea of combining nitrogen, iron, humic acid, potassium, sea kelp, and sulfur into a single product is appealing, especially if you’re looking for a simplified approach to lawn care. No one wants to spend their whole weekend mixing different formulas, right?

This liquid fertilizer aims to deliver a comprehensive solution for deep green color, root strength, stress resistance, and overall lawn health. The claim of covering up to 16,000 sq. ft. from a single gallon is substantial, suggesting a concentrated formula. I was particularly interested to see how the humic acid and sea kelp components would perform, as those are often overlooked but can make a noticeable difference in soil health and drought resistance. Let’s get into the details to see how it stacks up against the others.

Key Features

• 7-in-1 Complete Lawn Care Formula: This is the main selling point, promising a comprehensive blend of nutrients in one application. Simplifies the lawn care process, potentially saving time and effort.
• Nitrogen, Iron & Humic Acid for Deep Green Grass: The inclusion of iron is critical for that rich, dark green color that everyone wants. The humic acid is a nice touch, improving soil structure and nutrient availability.
• Potassium, Sea Kelp & Sulfur for Stronger, Healthier Turf: Potassium is essential for root development and overall plant health, while sea kelp adds beneficial micronutrients and improves stress tolerance. Sulfur contributes to improved soil health.
• Safe & Eco-Friendly: Claims of being safe for pets, kids, and plants is a major plus, especially for families with young children or animals.
• Easy-to-Apply Liquid Formula: Liquid fertilizers are generally easy to apply with a hose-end sprayer, ensuring even coverage across the lawn.

What We Like

• Comprehensive Nutrient Blend: The 7-in-1 formula offers a convenient way to provide a wide range of essential nutrients to the lawn. It’s like a multivitamin for your grass! This can be particularly beneficial for lawns with nutrient deficiencies or poor soil quality.
• Promotes Deep Green Color: The combination of nitrogen and iron should deliver noticeable results in terms of lawn color. I’ve used iron supplements in the past and have seen lawns transform from dull green to a vibrant, healthy shade.
• Easy Application: Liquid fertilizers are typically very easy to apply. Hook up a hose-end sprayer, and you’re good to go. This is a major advantage over granular fertilizers, which can be time-consuming and require specialized equipment for even distribution.
• Large Coverage Area: The coverage area of 16,000 sq. ft. is impressive for a 1-gallon container, making it a cost-effective option for larger lawns.

What Could Be Better

• Lack of Weed Control: Unlike some of the Scotts options in this list, this fertilizer doesn’t offer any weed control. You’ll need to use a separate weed killer if you have weed problems.
• Higher Price Point: At $59.99 per gallon, it’s one of the more expensive options per ounce on the list. While the comprehensive formula is appealing, budget-conscious users might find it less attractive.

Here’s a refined pros and cons table for clarity and readability:

Final Thoughts

This product is ideal for homeowners looking for a simple, all-in-one lawn care solution with a nutrient boost and vibrant green color. While it excels in enhancing lawn health, those seeking weed control may want to consider other alternatives, such as Scotts Turf Builder Weed & Feed.
