10 Best High Nitrogen Lawn Fertilizer Options for Deep Green Grass in 2026

The Simple Lawn Solutions Maximum Green & Growth Fertilizer is a 28-0-0 liquid concentrate designed to deliver a powerful nitrogen boost to your lawn. This product is ideal for homeowners looking to restore a deep green color and encourage rapid growth, especially after winter dormancy or a nitrogen deficiency. It comes with a convenient attached sprayer that automatically mixes the right amount of fertilizer with water, covering up to 3,200 square feet per bottle.

What sets this fertilizer apart is its dual release system: 70% of the nitrogen is quick-release for an immediate greening effect, while 30% is slow-release to keep feeding your lawn between applications. This means you'll see results in days, but the feeding lasts for weeks. The formula works on all common grass types, including Bermuda, St. Augustine, Zoysia, Fescue, and Kentucky Bluegrass, making it a versatile choice for most lawns.

In terms of ease of use, the attached sprayer is a big time-saver. Simply attach the bottle to your garden hose and spray. No measuring, no mixing, no cleanup. The sprayer applies a consistent ratio, so you don't have to worry about over- or under-fertilizing. However, the sprayer is made of plastic and may not be as robust as a standalone unit, but it works well for occasional use.

One limitation is that this product is strictly a nitrogen source lacking phosphorus and potassium, which are essential for root development and overall plant health. If your lawn needs a complete feed, you'll need to supplement with a balanced fertilizer. Also, because it's high in nitrogen, there's a risk of burning the grass if you apply too much or use it during hot, dry weather. Always follow the recommended application rates.

Overall, the Simple Lawn Solutions 28-0-0 is a solid choice for a quick green-up and growth boost. It's especially effective for correcting yellowing lawns or jump-starting spring growth. If you're looking for an easy, no-mess way to give your lawn a nitrogen rich feed, this product delivers good results at a reasonable price.

Scotts Green Max Lawn Food is a specialized fertilizer that combines lawn feeding with an iron supplement for rapid greening. Designed for homeowners who want a thick, deep green lawn fast, this product works on any grass type and can be used throughout the growing season. It's a popular choice for DIY lawn enthusiasts looking for an affordable boost without professional help.

The standout feature is the 5% iron content, which promotes deep greening in as little as three days. Real-world tests from thousands of users back this up; many report seeing a noticeable color change within the first week. The formula is also designed not to stain concrete or driveways when applied according to directions, a common worry with high-iron fertilizers. Application is straightforward with a spreader, and the bag covers 10,000 square feet, making it suitable for medium to large lawns. For best results, watering lightly after application speeds up the greening process.

In terms of build quality, the product comes as uniform granules that spread evenly using the recommended Scotts spreader settings. The instructions are clear, and the 33.33 lb bag is manageable for most homeowners. While the quick results are impressive, some users note that the deep green color can fade after a few weeks, requiring another application if you want to maintain the look. Additionally, the fertilizer has a strong ammonia-like odor that lingers for a day or two after spreading, which may be a minor inconvenience for some. A few reviewers also caution that uneven application or applying during hot weather can lead to patchy burn spots, so careful spreading is important.

Overall, Scotts Green Max Lawn Food delivers on its promise of fast greening without staining hard surfaces. It's a solid choice for anyone who wants an immediate visual improvement in their lawn's color. Just keep realistic expectations about longevity and be mindful to apply it evenly and at the right temperature. For the price, it offers good coverage and reliable performance for the average homeowner.

The Scotts Green Max Lawn Food is a granular fertilizer designed to give your lawn a fast, noticeable green-up. It's part of Scotts trusted lawn care line and comes in a 5,000 sq. ft. bag. If you're looking to boost your turf's color quickly before a party or just want a lush yard without the wait, this product is a strong contender.

The standout feature is the dual-action formula. It combines a nitrogen-rich feed with iron supplement, which helps deepen the green color in as little as three days. Many users appreciate that it doesn't stain concrete or stone when applied according to the instructions. Plus, you can walk on the lawn immediately after spreading, and kids and pets can re-enter right away - a major convenience for busy families.

This product works on any grass type, so you don't need to worry about compatibility. It's also designed to be part of the larger Scotts Lawn Care Plan, meaning you can schedule it alongside other Scotts products for season-long results. The bag is heavy (over 16 pounds) but manageable, and a standard broadcast spreader makes application straightforward.

One notable limitation is that Scotts Green Max is not sold in Florida. If you live there, you'll need to look for an alternative. Also, since this product has zero customer reviews at this time, you're relying on the manufacturer's claims rather than real-world data. That might give some buyers pause, but Scotts has a strong reputation in lawn care.

Overall, the Scotts Green Max Lawn Food delivers on its promise of fast, deep greening without staining. It's a solid choice for homeowners who want a vibrant lawn with minimal fuss. Just make sure you can get it in your area - and if you can, it's worth trying.

CountryMax Urea Fertilizer 46-0-0 is a professional-grade granular fertilizer designed for anyone who wants a fast, noticeable green-up in their lawn or garden. With a 46% nitrogen content, this product is ideal for correcting nitrogen deficiencies quickly, making it a go-to choice for homeowners, landscapers, and growers who need reliable results during the active growing season.

The standout feature here is the high nitrogen concentration. It promotes rapid plant growth, lush foliage, and that deep green color that makes a lawn look its best. The granules are uniform and spread easily with broadcast or drop spreaders, so you get consistent coverage without much fuss. In real-world use, you can expect to see results within days, especially if you water it in after application. It's versatile too, working well on lawns, gardens, crops, trees, shrubs, and ornamental plants.

Build quality is solid for a fertilizer. The 50 lb bag is sturdy and resealable, which helps keep the granules dry and free-flowing. The product is straightforward to use, but you do need to be careful with application rates. Too much can burn your plants, so follow the instructions closely. It's also worth noting that this is a straight nitrogen fertilizer, so for balanced growth, you may need to supplement with other nutrients depending on your soil's needs.

On the downside, the high nitrogen content means it's not a one-size-fits-all solution. If you're growing nitrogen-sensitive plants or have already rich soil, you'll want to test first. Also, because it's granular, it works best when watered in, which might be an extra step for some. But for the price, the 50 lb bag offers excellent coverage and value, especially for larger areas.

Overall, CountryMax Urea Fertilizer 46-0-0 is a solid choice for anyone needing a quick, effective nitrogen boost. It's easy to apply, versatile, and delivers on its promise of fast green-up. Just be mindful of application rates and your specific plant needs. If you're after a reliable high-nitrogen fertilizer, this one is worth considering.

Scotts Liquid Green Max Lawn Food represents a straightforward solution for homeowners who want a lush, green lawn without spending hours on maintenance. This liquid fertilizer and iron supplement is designed for anyone with grass, from the weekend warrior to the busy professional who values curb appeal but has limited time. The promise is simple: feed your lawn quickly and see fast results.

The standout feature is undoubtedly the speed of results. The 29-0-0 NPK formula, boosted with iron, delivers a noticeable deep green color in as little as three days. This isn't a slow-release product; it's designed for immediate visual impact. The application process lives up to its easy billing. Connecting the bottle to a standard garden hose turns lawn feeding into a simple spray-and-go operation. You can cover a 2,000 square foot area in about ten minutes, which redefines efficient lawn care.

From a design perspective, the product is thoughtfully executed. The reusable hose-end sprayer is a smart, eco-conscious choice that reduces plastic waste over time. The translucent bottle is a small but significant detail that solves a common pain point: you can actually see how much product you have left as you work, so there's no surprise when the bottle runs empty mid-application. The build quality feels consistent with Scotts' reputation for reliable lawn care products.

There are a couple of considerations. The initial purchase requires you to buy the sprayer applicator, and subsequent uses only need the refill bottle. This is great long-term but means a higher upfront cost. Also, because it's a fast-acting liquid, the results, while dramatic, may not last as long as some slow-release granular fertilizers, necessitating a regular seasonal schedule of about four applications per year for maintained perfection.

For a fast, easy, and effective way to green up your lawn with minimal effort, Scotts Liquid Green Max delivers on its core promises. It's particularly well-suited for giving your lawn a quick boost between longer-term feedings or for homeowners who prefer the simplicity of liquid application. If you want visible results quickly and value convenience over mixing bags of granular product, this is a compelling choice.

The Scotts Turf Builder Lawn Food is a straightforward, no-fuss fertilizer designed for homeowners who want a healthier lawn without complicated steps. It works on any grass type, so you don't have to worry about compatibility. Whether you have Bermuda, Fescue, Kentucky Bluegrass, or Zoysia, this product claims to feed and strengthen your turf effectively.

One standout feature is its focus on root development. By building deep, strong roots, the grass becomes better at absorbing water and nutrients compared to an unfed lawn. This can lead to improved drought tolerance and overall resilience. The formula is pesticide-free, which is a plus for those concerned about chemicals around kids and pets. Application is simple: you can spread it on a wet or dry lawn during spring, summer, or fall, making it a flexible choice for busy schedules.

The 12.5 lb bag covers up to 5,000 square feet, which is suitable for medium-sized yards. However, if your lawn is larger, you may need multiple bags. The product itself is lightweight (listed at 0.5 pounds, though that seems like a data error for a 12.5 lb bag). In practice, you'll want to use a spreader for even coverage. There are no reviews available yet, so real-world feedback is limited, but Scotts is a well-known brand in lawn care.

Potential drawbacks include the need for repeated applications to maintain results, as most fertilizers require regular feeding. Also, without user reviews, it's hard to gauge how well it performs in different climates or soil types. But based on the features, it's a solid choice for anyone looking for a general-purpose lawn food that's easy to use.

Overall, the Scotts Turf Builder Lawn Food offers a reliable way to feed your lawn without overcomplicating the process. If you're after a simple, effective fertilizer that works on all grass types and builds strong roots, this is worth considering. Just be prepared to reapply as needed for the best results.

Petramax Liquid Nitrogen Fertilizer 28-0-0 is a concentrated liquid lawn food designed to revive tired, yellowing grass and push it into a deep, vibrant green. This 32-ounce bottle is aimed at homeowners who want a fast-acting solution for nitrogen-deficient lawns without the hassle of granular applications. Whether you have warm-season Bermuda or cool-season fescue, this formula is made to work across all grass types.

The standout feature here is the dual-release technology. Seventy percent of the nitrogen is quick-release, giving you visible greening within days, while the remaining thirty percent is slow-release, feeding the grass steadily for weeks. This means you get an immediate boost plus ongoing nourishment between treatments. It's a practical approach for busy homeowners who don't want to reapply every few days.

Applying the fertilizer is straightforward. Mix 5 ounces per gallon of water for maintenance or 10 ounces per gallon to correct a nitrogen deficiency. Using a sprayer (PetraTools recommends their own, but any garden sprayer works) you can cover up to 12,800 square feet for maintenance or 6,400 square feet for correction. The liquid consistency makes it easy to get even coverage without the clumping or burning risk of some granular products, though you still need to follow mixing instructions carefully to avoid over-application.

On the downside, this is a nitrogen-only fertilizer (28-0-0). If your lawn needs phosphorus or potassium, you'll need to supplement with another product. Also, because it's a synthetic fertilizer, it's not suitable for organic gardening. Some users may also find the need to mix and spray less convenient than a hose-end sprayer or granular spreader, but for targeted feeding, the liquid form is actually more precise.

Overall, Petramax 28-0-0 delivers on its promise of fast, noticeable greening. The dual-release system is a genuine advantage, and the large coverage area makes the bottle last. If you're looking for a high-nitrogen boost to revive a lackluster lawn and don't mind a little mixing, this is a solid choice. PetraTools also backs it with a satisfaction guarantee and US-based customer support, which adds peace of mind.

Pennington Full Season Lawn Fertilizer is a single-application granular product designed to feed your lawn for up to four months. The 32-0-5 formula includes a high nitrogen content for vigorous growth, plus iron for deep greening. This fertilizer is best for homeowners who want a set-it-and-forget-it solution without the need for monthly reapplications.

The key innovation here is the polymer coated urea technology, which releases nitrogen slowly over time. This reduces the risk of fertilizer burn and ensures a steady supply of nutrients. Pennington also adds natural beneficial microorganisms to help revitalize the soil, improving root health and nutrient uptake. The 5% iron provides an immediate visual greening effect, making your lawn look lush without excessive fertilizer use.

The fertilizer comes in a sturdy 11.2 pound bag, covering about 5,000 square feet. The granules are fine and spread evenly with a standard broadcast spreader. The packaging is straightforward, with clear instructions for application rates and timing. It's designed for a single application in early spring, but you may need to adjust based on your local climate and grass type.

One limitation is availability: it's not sold in Hawaii or South Dakota due to regional regulations. Also, because this is a brand new product with no reviews yet, first-time buyers should be aware that long-term performance is unproven in the field. If you prefer a more traditional granular fertilizer with multiple applications per season, this all-in-one approach might not give you the flexibility to adjust feeding mid-season.

Overall, Pennington Full Season Lawn Fertilizer offers a convenient, season-long feeding solution with environmentally conscious slow-release technology and soil microbes. For homeowners looking to simplify lawn care while achieving a deep green lawn, this product is worth considering. Just check availability in your state and start with a small area to test its performance.

The Simple Lawn Solutions Maximum Green & Growth 28-0-0 is a high-nitrogen liquid fertilizer designed to give your lawn a powerful green-up and sustained growth through spring and summer. This product is perfect for homeowners who want a thick, vibrant lawn without the hassle of granular applications. Its 28-0-0 analysis means it's packed with nitrogen, the key nutrient for chlorophyll production and that deep green color you're after.

What sets this fertilizer apart is its dual-release nitrogen blend. 70 percent is quick-release for an immediate green boost, while 30 percent is slow-release to keep feeding your lawn between applications. In real-world use, that means you'll see results within days, and the effects last for weeks. The concentrated formula covers up to 12,800 square feet per gallon, making it a cost-effective choice for medium to large lawns.

The liquid form is easy to apply with a hose-end sprayer, and it works on all common grass types from Bermuda and St. Augustine to fescue and Kentucky bluegrass. The manufacturer, Simple Lawn Solutions, is a family-owned business with 25 years of commercial turf experience, so the quality and formulation are backed by real industry know-how.

On the downside, high-nitrogen fertilizers can burn your lawn if overapplied, so you need to follow the mixing and application rates carefully. Also, because it's a single-nutrient product, you'll still need to supply phosphorus and potassium separately for a complete lawn health plan. Some users may prefer granular options for convenience, but the liquid sprayer method gives you precise coverage.

Overall, the Simple Lawn Solutions 28-0-0 is a solid choice for anyone looking to revive a tired lawn or maintain vibrant growth during the active growing season. It delivers fast results, lasts between feedings, and covers plenty of ground. Just pair it with a balanced fertilizer program for the best long-term health.

If you're looking for a fast way to green up your lawn, Scotts Turf Builder Lawn Food is a solid choice. This 38-0-4 granular fertilizer is designed for all grass types and promises a noticeably greener lawn in just three days when used as directed. It's perfect for homeowners who want quick, visible results without a complicated routine.

The standout feature here is speed. Most fertilizers take a week or more to show color change, but Scotts delivers in three days. The high nitrogen content (38-0-4) fuels rapid green-up, and the two spreader settings give you control over the intensity. Use the standard Turf Builder rate for a thick, lush lawn or the Max Greening rate for an even deeper, more vibrant color (just check the label for any application restrictions).

Safety is another big plus. Once the product is watered in, it's safe for kids and pets to walk on the lawn immediately. That means less downtime and more time enjoying your yard. The application process is straightforward: spread on a dry lawn when temperatures are between 60°F and 90°F, then water in to activate the nutrients. A Scotts spreader makes it even easier, but any broadcast spreader should work.

There are a couple of things to keep in mind. You must water the fertilizer in after application, which might be tricky if your area is under watering restrictions or if you're in a dry spell. Also, the product works best in moderate temperatures, so avoid using it during heat waves or frost. The Max Greening setting may have additional restrictions, so always read the label before cranking it up.

Overall, Scotts Turf Builder Lawn Food is a reliable, fast-acting fertilizer that delivers on its promise of a greener lawn in three days. It's easy to use, safe for the family, and covers a generous 5,000 square feet per bag. If you want quick greening without a lot of fuss, this is a great option.
