Best Nitrogen For Grass Growth: 10 Lawn Fertilizers Compared

#1 · Best Overall

1. Simple Lawn Solutions 28-0-0

• Form: Liquid
• Weight: 2 lb

Best for: Quick color with split-release nitrogen.

Why it ranks #1: Its 28% nitrogen formula pairs 70% quick-release with 30% slow-release nitrogen, and the attached sprayer covers up to 3,200 square feet.

A 28-0-0 formula splits its nitrogen between 70% quick release and 30% slow release, pairing a fast color response with continued feeding between applications. The attached sprayer applies the product at its lawn-use ratio, making this liquid option a practical fit for homeowners treating up to 3,200 square feet.

The attached sprayer removes the need to measure a separate application ratio, and the stated coverage of up to 3,200 square feet helps you gauge whether one bottle suits the lawn. Its 70/30 quick- and slow-release nitrogen split combines a prompt nutrient response with feeding between applications. At 28% nitrogen, it targets lawns needing green color and growth; the product is listed for spring and summer and any grass type.

Skip it if you need to treat more than 3,200 square feet in one application; PetraMax Neighbor’s Envy lists coverage of 16,000 square feet.

Choose this for a spring or summer lawn needing nitrogen and a quick color response, with continued feeding between applications. The attached sprayer suits straightforward application, but its stated coverage is up to 3,200 square feet.

#2 · Highest Nitrogen

2. Supply Solutions 33-0-0

• Form: Granules
• Weight: 25 lb

Best for: Granular 33-0-0 turf feeding.

Why it ranks #2: The 33-0-0 granular formula has the highest stated nitrogen analysis here and includes sulfur for lawn and turf applications.

A 33-0-0 analysis with added sulfur gives Supply Solutions Rapid Green a nitrogen-focused granular format for turf, lawns, gardens, and crops. The listed combination supports a buyer seeking a fast-acting nitrogen feed alongside sulfur, rather than a hose-end liquid or a formula centered on multiple lawn nutrients.

The 33-0-0 analysis supplies concentrated nitrogen, while added sulfur is described as supporting uniform color and steady growth. Together, those features make the granular formula relevant to lawn and turf care as well as gardens and crops. Its powder-fertilizer listing indicates a spreadable solid rather than a liquid spray, so application involves handling granules. The provided details identify ammoniacal and urea nitrogen, giving buyers a clearer view of the nitrogen sources.

Skip it if you need a hose-end liquid application; Simple Lawn Solutions Maximum Green & Growth includes an attached sprayer for lawn use.

This suits buyers seeking concentrated granular nitrogen with sulfur for turf, lawns, gardens, or crops. Choose it when handling a solid fertilizer fits your routine; the supplied details do not specify lawn coverage or a sprayer.

#3 · Quick-Release Liquid

3. Petra 28-0-0 Liquid

• Form: Liquid
• Weight: 2 lb

Best for: Split-release 28-0-0 liquid feeding.

Why it ranks #3: This liquid 28-0-0 lawn fertilizer specifies 70% quick-release and 30% slow-release nitrogen for rapid greening and ongoing growth.

Petra’s 28-0-0 liquid fertilizer divides nitrogen into 70% quick-release and 30% slow-release portions, combining a rapid green response with continued feeding between applications. That split makes it relevant for nitrogen-deficient or yellow grass when the user is prepared to dilute the product with water and spray it.

The 28-0-0 analysis supplies a high nitrogen concentration for lawns seeking greener, quicker growth, while the 70/30 release split balances an initial response with ongoing feeding. Unlike a ready-to-spray bottle, the listed directions call for diluting the product with water and spraying the mixture, so application requires a mixing step. Its liquid form suits buyers comfortable with that workflow; the listing describes it for spring and summer lawn care.

Skip it if you want to attach a bottle directly to a hose; Simple Lawn Solutions Maximum Green & Growth includes an attached sprayer.

Consider this for a nitrogen-deficient lawn when you want a 28-0-0 liquid with both quick- and slow-release nitrogen. It suits buyers able to mix with water; the directions do not describe a ready-to-spray application.

#4 · Extended Feeding

4. Jonathan Green Veri-Green

• Form: Granules
• Weight: 45 lb

Best for: Extended feeding with iron greening.

Why it ranks #4: Its 29-0-3 granular formula includes iron and is described as feeding lawns for up to three months.

Jonathan Green Veri-Green pairs a 29-0-3 analysis with iron and gradual nutrient release for up to three months. The combination targets deep-green color and longer feeding intervals, making it a granular option for lawns where a spreader application and spring or fall timing suit the care routine.

The 29-0-3 analysis supplies nitrogen and potassium, while iron is included for deep-green color. Gradual, consistent nutrient release for up to three months can reduce how often feeding is needed compared with a short-interval program. Directions specify spreading onto a dry lawn in spring or fall using a rotary, drop, or handheld spreader. The listing says not to apply when the lawn is under heat or drought stress, an important boundary for scheduling.

Skip it if you need a liquid hose-end application; Sunday Green Machine is a liquid fertilizer applied with a hose and universal sprayer.

Choose this for granular spring or fall feeding when extended nutrient release and iron-associated greening are priorities. It requires a spreader and should not be applied to a lawn under heat or drought stress.

#5 · Broad Nutrient Blend

5. PetraMax Neighbor’s Envy

• Form: Liquid

Best for: Broad-coverage multi-nutrient feeding.

Why it ranks #5: The liquid 20-0-2 formula lists 20% nitrogen, 2.5% iron, humic acid, and stated coverage of 16,000 square feet.

Coverage of 16,000 square feet from a one-gallon liquid formula makes PetraMax Neighbor’s Envy a fit for larger lawns needing more than nitrogen alone. Its listed 20-0-2 analysis is paired with iron, humic acid, fulvic acid, and sea kelp in a combined lawn-care formula.

The one-gallon listing covers 16,000 square feet, helping homeowners plan a broad treatment with one liquid product. Alongside 20% nitrogen, the formula lists 2.5% iron, 3% humic acid, 1% fulvic acid, 1% sea kelp, potassium, and sulfur. That nutrient mix links nitrogen feeding to iron-associated deep color and soil enrichment from humic acid. It is a useful option when you want several listed nutrients together rather than a nitrogen-only formula.

Skip it if you want a 28% nitrogen liquid; PetraTools Petramax 28-0-0 offers a higher nitrogen concentration with quick- and slow-release feeding.

A good match for a larger lawn where broad coverage and several listed nutrients matter alongside nitrogen. Its liquid, seven-nutrient approach is less focused on maximum nitrogen concentration than a 28-0-0 product.

#6

6. Sunday Green Machine

• Form: Liquid
• Weight: 2.6 lb

Best for: Hose-applied liquid with broad coverage.

Why it ranks #6: Its 22-0-3 liquid formula combines nitrogen with seaweed, iron, and potassium, and the listing states 10,000-square-foot coverage.

Sunday Green Machine covers 10,000 square feet per two-pack and applies by attaching the pouch and universal sprayer to a hose. Its 22-0-3 liquid formula combines nitrogen with seaweed, iron, and potassium, giving homeowners a broad-coverage option that links feeding with rooting and lawn fortification.

The hose-and-universal-sprayer directions make application a connect-and-spray workflow, while the stated 10,000-square-foot coverage helps plan treatment for a larger lawn. Its 22-0-3 formulation combines nitrogen with iron, seaweed, and potassium; the listing connects these ingredients with deep rooting and fortifying grass. As a liquid product, it avoids granular spreading, but the supplied directions specifically call for attaching the pouch and sprayer to a hose.

Skip it if you cannot use a hose for application; Scotts Turf Builder Lawn Food can be applied to wet or dry grass as a powder.

This fits homeowners seeking a hose-applied liquid treatment with listed coverage of 10,000 square feet and several nutrients. Choose it when the hose-and-sprayer workflow works for your lawn; it is not a hose-free application.

#7

7. GreenView Fairway Formula

• Form: Granules

Best for: Fall lawn recovery and preparation.

Why it ranks #7: This granular fall fertilizer is intended for any grass type and emphasizes steady greening, deep roots, and seasonal lawn preparation.

GreenView Fairway Formula is specifically positioned for fall, linking lawn feeding with summer-damage repair and preparation for winter. Its granular formula promises steady, even greening without surge growth, making it a seasonal choice for homeowners prioritizing root development and a better spring lawn over an all-season liquid application.

The fall-use focus gives this fertilizer a defined place in a seasonal routine: it is described as repairing summer damage and preparing lawns for winter. Its steady, even greening without surge growth suits buyers who want gradual-looking color rather than a sudden growth push. The product also highlights deep root growth, thickening, and use on any grass type. As a granular fertilizer, it is handled as a solid application, and the directions warn against hand spreading.

Skip it if you want a liquid hose-end application; Sunday Green Machine is a liquid formula applied with a hose and universal sprayer.

Pick this for fall lawn care focused on summer recovery, roots, and winter preparation across any grass type. It is a granular product, and its directions rule out hand spreading, so plan for another application method.

#8

8. Scotts Turf Builder Lawn Food

• Form: Powder
• Weight: 12.5 lb

Best for: Flexible any-season lawn feeding.

Why it ranks #8: The granular lawn food suits any grass type and is described as feeding grass and building strong, deep roots, but no nitrogen analysis is listed.

Scotts Turf Builder Lawn Food can be applied to wet or dry grass in spring, summer, or fall, giving its schedule unusual flexibility. The formula is listed for any grass type and aims to strengthen grass and build deep roots, making it a practical general-purpose option for routine lawn feeding.

The wet-or-dry application guidance reduces the need to wait for one specific lawn condition, while the spring, summer, or fall timing leaves room to fit feeding into different seasonal routines. Scotts says the food builds strong, deep roots that improve water and nutrient absorption compared with an unfed lawn. It is also listed for any grass type and is pesticide-free, a useful distinction for buyers seeking lawn food rather than a pesticide-containing treatment.

Skip it if you need stated square-foot coverage to plan an application; Sunday Green Machine lists coverage of 10,000 square feet for its two-pack.

A sensible choice for lawn owners who want seasonal flexibility and root-focused feeding across any grass type. Application is listed for wet or dry grass, but the supplied product details do not give a coverage area.

#9

9. Simple Lawn Solutions Growth Booster

• Form: Liquid
• Weight: 2 lb

Best for: New seeding and lawn repair growth.

Why it ranks #9: This ready-to-use liquid is intended for growth, new sod, seeding, and lawn repair, but the supplied listing gives no nitrogen analysis.

A ready-to-use hose-end sprayer pairs Simple Lawn Solutions’ nitrogen-and-phosphorus fertilizer with humic acid, targeting vertical and lateral growth. The listing specifically calls out new sod, seeding, nutrient deficiency, and lawn repair, making this a growth-oriented option for establishing or thickening turf across a range of grass types.

The ready-to-spray bottle connects to a hose, so application avoids a separate dilution step and supports even spraying across prepared new sod, seed, or a lawn needing repair. Nitrogen and phosphorus provide the fertilizer base, while humic acid is identified as part of the growth-boosting formula. Its listed suitability spans grass types including Bermuda, St. Augustine, fescue, and Kentucky bluegrass. The focus is growth and establishment, rather than a stated long-duration feeding schedule.

Skip it if you need stated coverage before spraying a measured lawn; Simple Lawn Solutions Maximum Green & Growth lists coverage up to 3,200 square feet.

A fit for homeowners establishing new sod or seed, repairing a lawn, or seeking vertical and lateral growth with a hose-end spray. The listing spans many grass types, but does not specify coverage per bottle.

#10

10. TPS Nutrients High Nitrogen

• Form: Liquid

Best for: Small-bottle vegetative growth boost.

Why it ranks #10: The liquid is described as high nitrogen for residential turf growth, but no NPK analysis, coverage, or application rate is supplied.

TPS Nutrients packages its high-nitrogen lawn boost in an 8-ounce liquid bottle focused on leaf and blade development. That emphasis suits residential lawn routines seeking thicker turf and greener color, while the compact listed size is a natural fit for buyers considering a smaller-scale liquid treatment rather than a broad-coverage product.

The product description connects nitrogen with vegetative growth, specifically leaf and blade development, so its main purpose is turf thickening and color rather than a multi-nutrient lawn program. Its liquid form gives it a different handling format from granular fertilizers, and the residential-lawn positioning suits ordinary yard and landscaping routines. The listing does not provide an NPK analysis, application directions, or coverage figure, so buyers cannot use the supplied facts to calculate a treatment rate or area.

Skip it if you need a stated coverage area and hose-sprayer instructions; Sunday Green Machine lists both a 10,000-square-foot coverage and hose application.

Choose this for a residential lawn routine centered on greener color and thicker vegetative growth in liquid form. It may not suit buyers who need a stated application rate or coverage figure before treating a defined area.
