Best Low Nitrogen Fertilizer For Lawns: 10 Options Compared

#1 · Best Overall

1. Milorganite 6-4-0 Fertilizer

• Form: Pelletized
• Weight: 32 lb

Best for: Slow feeding with iron greening.

Why it ranks #1: Its 6-4-0 analysis has the lowest stated nitrogen percentage here, and the pelletized formula includes iron and slow-release feeding.

Organically complex iron that greens grass without staining concrete is the defining advantage of Milorganite 6-4-0. This bundle pairs a 32-pound bag of pelletized fertilizer with a printed feeding and spreader tips brochure, giving lawn keepers seasonal application guidance alongside the product.

The low-salt formula is described as helping avoid streaks, stripes, and fertilizer burn, including in hot or dry conditions, which can reassure buyers concerned about uneven application effects. Its slow-release feeding supports a more gradual nutrient supply rather than a quick feed. The printed brochure adds seasonal application and spreader tips to the 32-pound bag. Milorganite has an earthy aroma when first applied; rain or watering can help reduce it as it dissipates.

Skip it if you want a plant-based formula without biosolids; Purely Organic Products Lawn Food lists soy and distillers grains instead.

Pick this for gradual feeding and iron-based greening, especially if spreader guidance is useful. Its heat-dried-microbe ingredients and initial earthy aroma are important considerations for buyers who prefer a different ingredient profile.

#2 · Best 10-0-2

2. Purely Organic Lawn Food

• Form: Granules
• Weight: 15 lb

Best for: Phosphate-restricted lawn feeding.

Why it ranks #2: The 10-0-2 formula specifies no phosphorus and uses plant-based ingredients, making its nutrient analysis clear for low-N shoppers.

A 10-0-2 analysis with no phosphorus is the defining feature of Purely Organic Products Lawn Food, making it a fit where local rules restrict phosphate use. Its plant-based blend of distillers grains and soy also offers a way to feed turf without manure or smelly biosolids.

This granular lawn food promotes green turf while the zero-phosphorus analysis addresses phosphate restrictions set by towns and municipalities. The plant ingredients—soybean meal, L-lysine monohydrochloride, and distillers dried grains—give buyers a clearly stated formula rather than manure-based or biosolid ingredients. It covers 3,000 square feet, a useful planning point for spreading. The manufacturer also states there is no re-entry waiting period after application for family and pets.

Skip it if you need phosphorus in a lawn feed; Milorganite 6-4-0 includes phosphorus in its analysis.

This suits homeowners seeking plant-based granular feeding under phosphate restrictions, with stated coverage for a 3,000-square-foot lawn. The zero-phosphorus analysis is the key fit consideration if your lawn-care plan calls for that nutrient.

#3 · Best Weed Prevention

3. Jonathan Green Corn Gluten Fertilizer

• Form: Granules
• Weight: 15 lb

Best for: Corn gluten weed prevention.

Why it ranks #3: Its 10-0-2 analysis keeps nitrogen below many listed formulas, while the product also prevents sprouting weeds and covers 5,000 square feet.

Corn gluten makes Jonathan Green’s 10-0-2 fertilizer distinctive: the product is described as preventing crabgrass, dandelions, and more than 25 other weeds while gently feeding turf. Its 15-pound bag covers 5,000 square feet, and it can also be used in flower gardens and planting beds.

The granular formula combines lawn feeding with weed prevention, making it relevant to established lawns where sprouting weeds are a concern. The listed schedule allows application up to four times a year between March and November, including early and late spring and fall. Its stated safety around children and pets is useful for family yards. There is an important workflow constraint: it cannot be used at the same time as seeding a new lawn.

Skip it if you are seeding new grass now; Jonathan Green & Sons Organic Lawn Food 10-0-1 is listed for new grass.

Choose this for a lawn where corn gluten weed prevention and gentle feeding are both priorities, with additional use in beds and gardens. Avoid it during new-lawn seeding, which conflicts with its stated application guidance.

#4 · Extended Feeding

4. Jonathan Green Organic Lawn Food

• Form: Granules

Best for: Eight-to-ten-week organic feeding.

Why it ranks #4: This granular 10-0-1 formula includes iron and provides gradual nutrient release for eight to ten weeks.

Gradual nutrient release over eight to ten weeks is the key feature of Jonathan Green & Sons Organic Lawn Food 10-0-1. Its granular formula includes iron and is listed for established lawns and new grass, making it a fit for homeowners seeking sustained feeding across more than one turf stage.

The 10-0-1 analysis and stated nutrient release period support a feeding plan that does not require treating the product as a short-duration feed. Iron is included to promote healthy growth and color, while the listing identifies suitability for established lawns and new grass. The pack is a case of two, which gives buyers multiple units to manage or store. Safety information says to keep it away from children and pets and store it in a cool, dry place.

Skip it if you need a single-pack purchase; Jonathan Green Corn Gluten Lawn Fertilizer is listed as one quantity.

Consider this for sustained granular feeding on established turf or new grass, especially if iron and a longer release period suit your plan. The two-pack case and stated child-and-pet precautions are relevant handling considerations.

#5

5. Scotts Turf Builder WinterGuard

• Form: Granules
• Weight: 8 oz

Best for: Fall recovery and winter prep.

Why it ranks #5: It is designed for fall feeding and root preparation, but the supplied product data does not state its NPK analysis for comparison.

Fall application is the defining feature of Scotts Turf Builder WinterGuard: it feeds grass as it recovers from summer heat, drought, and activity, while helping build deep roots ahead of winter. It’s a seasonal option for homeowners focused on preparing their lawn for spring rather than feeding year-round.

The granules can go onto a wet or dry lawn in fall, giving you flexibility around watering and weather. Scotts lists settings for its broadcast/rotary and drop spreaders, which helps make application more straightforward if you use that equipment. The formula is intended for any grass type and supports root development through winter preparation. It is also described for smaller yards, so its application context is more limited than broad acreage coverage.

Skip it if you need fertilizer for spring or summer; Scotts Turf Builder Lawn Food is presented for fast greening instead.

Choose this for a smaller lawn needing fall recovery and root preparation before winter, especially if you have a Scotts spreader. Its seasonal role is the main boundary: it is not presented as an all-season feeding solution.

#6

6. GreenView Fairway Formula Fall Fertilizer

• Form: Granules

Best for: Steady fall lawn greening.

Why it ranks #6: Its fall-focused formula supports root growth and steady greening, but the listed data gives no nitrogen percentage to verify low-N fit.

Steady, even greening without surge growth distinguishes GreenView Fairway Formula Fall Lawn Fertilizer. Its fall-focused role is to repair summer damage, encourage deep roots, and prepare grass for winter and a better spring lawn, making it a seasonal choice for pre-winter yard care.

The granular fertilizer is described for any grass type, so the seasonal plan does not depend on a specific turf variety. Its proprietary blend combines immediate-release and other nitrogen forms according to the product description, connecting a fall application with both greening and preparation for winter. The directions caution against hand spreading, so buyers need an appropriate spreading method rather than applying it by hand. The listing also identifies one-time use when seeding a new lawn area.

Skip it if you need to apply fertilizer by hand; Scotts Turf Builder WinterGuard includes Scotts spreader settings for application.

This is a seasonal fit for homeowners preparing any grass type for winter and seeking even rather than surge growth. Plan to use a suitable spreader, since the safety information specifically says not to hand spread.

#7

7. The Andersons PGF 16-0-8

• Form: Granules
• Weight: 18 lb

Best for: Extended feeding for spreader users.

Why it ranks #7: The 16-0-8 analysis is phosphorus-free and includes iron, micronutrients, and slow-release feeding, though its nitrogen is higher than the leading options.

Quick- and slow-release nitrogen provide immediate and extended feeding for up to eight weeks in The Andersons Professional PGF 16-0-8. Its super-fine particles offer twice the number of particles per square foot, a feature intended to support even distribution across the lawn.

The 16-0-8 phosphorus-free blend pairs the particle-size approach with iron, micronutrients, and Humic DG, giving buyers several listed lawn nutrients in one granular application. MUtech-coated slow-release nitrogen supports continued feeding after the quick-release portion, while the stated eight-week duration helps frame the maintenance interval. The directions call for a clean, dry spreader and require unused product to be removed rather than left in the equipment. Sale is restricted in California and Oregon.

Skip it if you live in California or Oregon; Scotts Turf Builder Lawn Food is another listed granular lawn feed.

This suits spreader users looking for phosphorus-free feeding with both quick and extended nitrogen release, plus iron and micronutrients. Its regional sales restriction rules it out for lawn keepers in California and Oregon.

#8

8. PetraMax Neighbor’s Envy

• Form: Liquid

Best for: Liquid multi-nutrient lawn care.

Why it ranks #8: Its supplied ingredient analysis is 20-0-2, so it offers no phosphorus but has substantially more nitrogen than the lower-N choices.

A 7-in-1 liquid formula combines nitrogen, iron, humic and fulvic acids, and sea kelp, giving PetraMax Neighbor’s Envy a broad nutrient profile in one product. The listed 20-0-2 analysis and 2.5% iron target grass growth and deep color without mixing several separate products.

The liquid format sets this apart from granular feeds and may suit lawn keepers who prefer applying a solution. Its ingredients combine 20% nitrogen and 2% potassium with iron, sulfur, humic acid, fulvic acid, and sea kelp, connecting turf feeding with soil-enrichment ingredients in one formula. The product is listed for 16,000 square feet, a substantial coverage figure for planning a larger lawn application. The supplied details do not specify an applicator or spreader setting.

Skip it if you want a granular feed with spreader guidance; Scotts Turf Builder WinterGuard lists Scotts spreader settings.

This fits buyers seeking a liquid, multi-ingredient lawn treatment for a larger area and value having iron and soil-oriented ingredients in one formula. Check the application workflow against your equipment, since no tool or setting is specified here.

#9

9. Scotts Turf Builder Liquid Lawn Food

• Form: Liquid
• Weight: 8.32 oz

Best for: Quick hose-end liquid feeding.

Why it ranks #9: The 29-0-3 liquid formula is easy to apply with a hose-end sprayer, but its nitrogen content is high for this search.

A hose-end sprayer attachment makes Scotts Turf Builder Liquid Lawn Food the quick-application option in this roundup, with a 32-fluid-ounce bottle stated to feed and water 2,000 square feet in about 10 minutes. Its 29-0-3 formula supplies nitrogen and potassium for turf growth.

The liquid format avoids filling a granular spreader, and the translucent bottle lets you see how much lawn food you are using during application. Its 29-0-3 analysis links nitrogen with thicker, greener grass and potassium with everyday stress resistance. The reusable spray applicator is intended to work with refill bottles sold separately, so buyers can reuse the applicator but need a refill for subsequent use. The product is listed for any grass type.

Skip it if you want to avoid a hose-end liquid application; The Andersons Professional PGF 16-0-8 is a granular spreader option.

This suits DIY homeowners wanting a hose-end liquid feed for a lawn up to the stated coverage, with visible bottle contents during spraying. Factor in the separate refill purchase if you plan to reuse the applicator.

#10

10. Scotts Turf Builder Lawn Food

• Form: Granules

Best for: Fast granular lawn greening.

Why it ranks #10: Its verified 38-0-4 analysis is nitrogen-rich and aimed at rapid greening, making it the weakest fit for a low-nitrogen search.

A visible green-up in as little as three days is the defining promise of Scotts Turf Builder Lawn Food when used as directed. Its 38-0-4 nitrogen-rich analysis supports fast greening, while the granular formula and Scotts spreader settings provide a familiar application route for lawn owners.

Scotts says the product can be applied with a Scotts spreader using the label’s settings, giving owners of that equipment a straightforward way to distribute the granules. The 38-0-4 analysis supplies nitrogen and potassium, and the stated three-day greening window makes it relevant when visible color is the priority. For children and pets to return immediately after application, the product information specifies that the lawn must first be watered in.

Skip it if you prefer a hose-end liquid application; Scotts Turf Builder Liquid Lawn Food attaches to a hose-end sprayer.

Choose this when fast visible greening from a granular nitrogen feed is the priority and you can water it in before family or pets return. The Scotts spreader workflow is a practical fit consideration.
