Shopping for fertilizer for grass comes down to matching the product to your lawn’s season, age, and problem spots. For most homeowners, Scotts Turf Builder Lawn Food (37.5 lbs.) is the best overall pick because it works on any grass type, feeds for months, and fits nearly every feeding window. If you are seeding or sodding, Scotts Turf Builder Starter Food for New Grass builds roots faster, while Scotts Green Max Lawn Food delivers the fastest visible green-up when your lawn looks tired. The main tradeoffs in this category are convenience versus cost per square foot, single-purpose feeds versus combination products with weed or insect control, and granular versus liquid application. Read on for the full breakdown of all 15 options and which one fits your lawn best.

Key Takeaways
- Scotts dominates this lineup with ten of fifteen products, which means the real decision is rarely brand versus brand — it is which Scotts formula matches your season and lawn stage.
- Cost per square foot varied widely: large-bag fall products like GreenView Fall Lawn Food (15,000 sq. ft. coverage) cost far less per area than liquid concentrates like Simple Lawn Solutions.
- Combination products (Weed & Feed3, SummerGuard, Triple Action Built for Seeding) save application time but lock you into one feeding window — a real drawback if conditions are not right.
- Liquid fertilizers (Scotts Liquid Lawn Food, Simple Lawn Solutions) green up fastest but feed for weeks, not months, making them supplements rather than replacements for granular programs.
- New-grass formulas appeared in both small (15 lbs.) and large (42 lbs.) sizes, and choosing the wrong size is the most common waste of money for seeding projects.

More Details on Our Top Picks
Scotts Turf Builder SummerGuard Lawn Food with Insect Control
Lawn owners fighting summer stress and bug damage at the same time get the most value from a two-in-one approach, and that is exactly where SummerGuard earns its place. It feeds grass to build resilience against heat and drought while knocking back ants, chinch bugs, armyworms, fleas, and ticks in a single pass. Compared with Scotts Turf Builder Lawn Food, which feeds only, this pick trades a little simplicity for real pest control, which matters most in southern and midsummer climates where chinch bugs thrive.
The tradeoffs are real: the lawn must be dry at application, and you cannot apply other weed, disease, or insect products for a full week afterward. It is also seasonal by design — for general spring or fall feeding, the standard Turf Builder is the better fit.
Pros:- Feeds grass while strengthening it against heat and drought stress
- Controls a long list of common lawn insects including chinch bugs, fleas, and ticks
- Works on any grass type
- One 13.35 lb. bag covers a full 5,000 sq. ft.
Cons:- Must be applied to a dry lawn, which limits scheduling flexibility
- Cannot use other weed, disease, or insect control products for at least one week after application
Best for: Homeowners in hot climates dealing with summer insect damage who want to feed and treat in one application
Not ideal for: Lawns without pest problems — the insecticide component is wasted money, and plain Turf Builder Lawn Food does the feeding job for less fuss
- Brand:Scotts
- Model Number:49013
- Weight:13.35 lbs.
- Coverage:5,000 sq. ft.
- Grass Types:Any grass type
- Listed Insects:Ants, armyworms, chinch bugs, crickets, fleas, grasshoppers, spiders, ticks
- Application Timing:Dry lawn in summer when insect activity first appears
Our verdict“If summer bugs and heat stress are hitting your lawn at once, this is the most efficient single-pass solution in the lineup.”
Scotts Turf Builder Starter Food for New Grass, 42 lb
Starting a lawn from seed or sod is a different nutritional job than maintaining one, and this is where a 24-25-4 starter ratio matters. The high phosphorus content pushes root development — the thing new grass needs most — rather than the top-heavy green growth that maintenance fertilizers prioritize. Compared with Scotts Turf Builder Triple Action Built for Seeding, which adds weed prevention to the mix, this 42 lb. bag goes all-in on establishment and covers a generous 14,000 sq. ft., making it the stronger choice for full-yard sod jobs or large seeding projects.
The obvious limitation: this is not an all-purpose lawn food. Once roots are established, continuing with it wastes the phosphorus-heavy formula, and a maintenance product like Scotts Green Max becomes the smarter next step.
Pros:- Phosphorus-rich 24-25-4 ratio built specifically for root and blade development
- Works for seed, sod, and grass plugs
- Covers a large 14,000 sq. ft. per bag
- Suitable for all grass types
Cons:- Narrow purpose — designed for new grass, not general lawn feeding
- 42 lb. bag is heavy to carry and pour into a spreader
Best for: Homeowners seeding, sodding, or plugging a large new lawn who want maximum establishment coverage per bag
Not ideal for: Established lawns — the starter ratio is wasted on mature grass, and a maintenance fertilizer delivers better results
- Weight:42 lbs
- Coverage:14,000 sq. ft.
- Fertilizer Ratio:24-25-4
- Suitable For:All grass types, sod, and grass plugs
- Purpose:New grass establishment
- Brand:Scotts
Our verdict“If you are establishing a new lawn from scratch, this starter formula gives seedlings and sod the root support that maintenance fertilizers simply do not provide.”
Scotts Green Max Lawn Food
When the goal is a visibly greener lawn before the weekend, few products compete with this fertilizer-plus-iron formula. The iron does the heavy lifting, producing deep greening in as little as three days — a speed that nitrogen-only feeds like Scotts Turf Builder Lawn Food cannot match, since nitrogen greening takes a week or more of growth. The stain-free guarantee matters too, because standalone iron products are notorious for marking driveways and sidewalks.
The tradeoff is scope: this is a color-focused product, not a complete seasonal program. It does not address soil health the way The Andersons PGF Complete with Humic DG does, and buyers in Florida cannot purchase it at all. For pale, iron-hungry lawns, though, nothing in this lineup delivers faster visual results.
Pros:- Visible deep greening in as little as three days
- Combines fertilizer and iron in a single application
- Guaranteed not to stain surfaces when used as directed
- Safe for any grass type with immediate re-entry
Cons:- Not available for sale in Florida
- Focused on color rather than long-term soil and root nutrition
Best for: Homeowners who need rapid visual greening before an event or listing photos and whose lawns look pale despite normal feeding
Not ideal for: Florida residents, and anyone seeking long-term soil nutrition rather than a fast color boost
- Weight:16.67 lbs
- Formula:2-in-1 fertilizer and iron supplement
- Greening Time:As little as 3 days
- Grass Compatibility:Any grass type
- Re-entry:Immediately after application
- Availability:Not sold in Florida
Our verdict“This is the pick when the lawn needs to look dramatically better in days, not weeks.”
The Andersons Professional PGF Complete 16-4-8 Fertilizer with 7% Humic DG
This is the enthusiast’s choice in the lineup. The balanced 16-4-8 ratio mirrors what golf-course managers use, and the inclusion of 7% Humic DG feeds soil biology — something no Scotts product in this roundup does. The super-fine particle size is not a marketing detail: it means every spreader pass distributes nutrients far more evenly than the coarser granules in Scotts Turf Builder SummerGuard, eliminating the streaking that plagues DIY lawns. Combined quick- and slow-release nitrogen delivers both an immediate response and up to eight weeks of feeding.
That performance comes with responsibility. The concentrated formula punishes careless application with burn spots, and California buyers cannot order it. For lawn-care hobbyists who own a decent spreader and want results a step above big-box products, it justifies the premium.
Pros:- Super-fine particles distribute evenly and reduce streaking
- Quick- and slow-release nitrogen provides immediate feeding plus up to 8 weeks of nutrition
- Includes iron, micronutrients, and Humic DG for soil health
- Professional 16-4-8 ratio suited to high-performance turf
Cons:- Requires careful, calibrated application to avoid over-fertilizing and burning
- Not available for sale in California
- Coverage limited to 5,000 sq. ft. per package, adding cost for large lawns
Best for: Lawn enthusiasts who calibrate their spreader, want golf-course-grade nutrition, and care about soil health
Not ideal for: Casual lawn owners or beginners — the concentrated formula makes over-application mistakes easy and costly
- Brand:The Andersons
- NPK Ratio:16-4-8
- Humic DG:7%
- Coverage Area:5,000 sq. ft.
- Nitrogen Release:Quick and slow release
- Feeding Duration:Up to 8 weeks
- Included Nutrients:Iron, micronutrients, Humic DG
- Restrictions:Not for sale in California
Our verdict“For serious lawn hobbyists who treat fertilizing as a craft, this professional-grade formula outperforms every consumer product here — if you apply it carefully.”
Scotts Turf Builder Lawn Food, 37.5 lbs.
This is the default recommendation for most lawns, and the reasoning is simple: flexibility and coverage. It works on any grass type, applies to wet or dry grass, and feeds in spring, summer, or fall — no timing windows, no dry-lawn requirements like Scotts SummerGuard imposes. One 37.5 lb. bag covers up to 15,000 sq. ft., the best coverage-per-bag in this entire roundup, which matters for anyone with a half-acre lot. The pesticide-free formula focuses on building deep roots that absorb water and nutrients better than an unfed lawn, making it a safe foundation for households with kids and pets playing outside.
Its limits are honest ones: it solves no special problems. No insect control, no fast greening like Green Max, no starter nutrition — just dependable feeding that needs repeating each season.
Pros:- Works on any grass type in any season — spring, summer, or fall
- Pesticide-free formula safe for households that use the lawn
- Builds deep roots for improved water and nutrient absorption
- Covers up to 15,000 sq. ft. per bag — the best value per square foot in the roundup
Cons:- Requires seasonal reapplication for sustained results
- 37.5 lb. bag is heavy and awkward for smaller users to handle
Best for: Owners of medium-to-large lawns who want one dependable, all-season, pesticide-free fertilizer for the whole year
Not ideal for: Anyone with a specific problem — pests, new seed, or pale color — since specialized picks in this lineup handle those jobs better
- Brand:Scotts
- Weight:37.5 lbs
- Coverage:15,000 sq. ft.
- Suitable Grass Types:Any grass type
- Application Seasons:Spring, summer, or fall
- Pesticide-Free:Yes
- Application Conditions:Wet or dry lawn
Our verdict“If you want a single fertilizer that handles a big lawn across every season without special requirements, this is the safest all-around buy.”
Scotts Turf Builder WinterGuard Fall Lawn Food, 10 lbs
Not every lawn needs a 40-pound bag of fertilizer sitting half-used in the garage. This 10 lb WinterGuard bag is sized for the homeowner with a modest yard, covering up to 4,000 sq. ft. while doing the same seasonal job as its larger sibling, the Scotts Turf Builder WinterGuard 32.3 lb bag — rebuilding roots stressed by summer heat and setting up a faster spring green-up. Compared with year-round products like Scotts Turf Builder Lawn Food, this one is purpose-built for fall application, channeling the plant’s energy downward into roots instead of top growth. The tradeoff is real: apply it outside the fall window and you lose most of the benefit. It also feeds only — no weed control, unlike the Triple Action Built for Seeding elsewhere in this lineup.
Pros:- Right-sized bag for small lawns with no leftover fertilizer to store
- Helps lawns recover from summer heat, drought, and foot traffic
- Builds deep roots for winter survival and stronger spring growth
- Works on any grass type, wet or dry
Cons:- Fall-only timing — results drop sharply if applied in the wrong season
- 4,000 sq. ft. coverage means multi-bag purchases for larger properties
Best for: Owners of small-to-medium lawns (under 4,000 sq. ft.) who want to winterize without leftover product
Not ideal for: Homeowners with larger yards — one bag won’t stretch, making the bigger WinterGuard size more economical
- Brand:Scotts
- Product Type:Fall Lawn Food
- Weight:10 lbs
- Coverage Area:4,000 sq. ft.
- Application Season:Fall
- Grass Type Compatibility:Any grass type
- Application Conditions:Wet or dry lawn
Our verdict“Buy this if you have a small lawn and want fuss-free winter prep; skip it if your yard needs the larger WinterGuard bag.”
GreenView Fall Lawn Food, Lawn Fertilizer, 48 lb Bag – Covers 15,000 Sq. Ft.
If your property is measured in fractions of an acre, bag count matters more than anything else. This 48 lb GreenView bag covers 15,000 sq. ft. in a single pass — three times the reach of the Scotts WinterGuard 10 lb bag — which means fewer trips to the store and fewer half-finished applications. Its 22-0-10 NPK formula with GreenSmart technology feeds continuously for up to 8 weeks, a slower release pattern than typical granular feeds, and it pushes the same fall priorities: root depth, winter hardiness, and faster spring green-up. The zero-phosphorus formula is the tradeoff to weigh. Lawns with phosphorus-deficient soil (a soil test will tell you) won’t get that nutrient here, whereas The Andersons PGF Complete 16-4-8 in this roundup does include it.
Pros:- Covers up to 15,000 sq. ft. — one of the largest single-bag coverages available
- Continuous feeding for up to 8 weeks reduces reapplication frequency
- High-potassium formula strengthens roots for winter protection
- Speeds up spring green-up after dormancy
Cons:- Fall-only use, not a year-round feeding solution
- Zero phosphorus may leave nutrient-poor soils underfed
Best for: Owners of large properties (1/3 acre or more) who want one bag to cover the whole lawn
Not ideal for: Small-lawn homeowners stuck with 40+ pounds of leftover fertilizer to store, or lawns needing phosphorus
- Coverage:15,000 sq. ft.
- Bag Weight:48 lbs
- NPK Ratio:22-0-10
- Feeding Duration:Up to 8 weeks
- Application Season:Fall
- Technology:GreenSmart Enhanced Efficiency
Our verdict“This makes sense for big-lawn owners who value coverage per bag over flexibility; smaller yards should look elsewhere.”
Scotts Turf Builder Triple Action Built for Seeding, 17.2 lbs.
Planting new grass usually means choosing between feeding seedlings and fighting weeds — this product refuses that choice. Triple Action Built for Seeding blocks crabgrass, dandelion, clover, and other listed weeds for up to 6 weeks while being gentle enough for sprouting grass, something a standard starter food or the regular Turf Builder Lawn Food simply cannot do. Compared with Scotts Turf Builder Weed & Feed3 in this roundup, the distinction is timing: Weed & Feed3 targets established lawns with existing weeds, while this one is strictly a pre-emergent for bare or freshly seeded ground. Two constraints shape the buying decision. It will not kill weeds that have already sprouted, and the application window demands consistent temperatures between 60°F and 90°F, which narrows usable dates in many regions.
Pros:- Prevents weeds without harming germinating grass seed
- Combines pre-emergent weed control and fertilizer in one step
- Blocks a wide list of common weeds including crabgrass and dandelion for 6 weeks
- Covers 4,000 sq. ft. per bag
Cons:- Pre-emergent only — existing weeds survive untouched
- Requires a 60°F–90°F temperature window, limiting application timing
Best for: Homeowners seeding a new lawn or overseeding who need weed protection during germination
Not ideal for: Anyone hoping to kill established weeds — this only prevents weeds that haven’t sprouted yet
- Size:17.2 lbs
- Coverage:4,000 sq. ft.
- Application Temperature:60°F to 90°F
- Weed Prevention Duration:Up to 6 weeks
- Formula:Triple Action (weed preventer + lawn food)
- Suitable Grass Types:Kentucky Bluegrass, Tall Fescue, Perennial Ryegrass, Centipedegrass, Fine Fescues
- Target Weeds:Dandelion, crabgrass, clover, chickweed, ground ivy, henbit, nutsedge
Our verdict“If you’re seeding this season, this is the purpose-built pick; if weeds are already growing, choose a weed-and-feed for established lawns instead.”
Scotts Turf Builder Liquid Lawn Food, 32 fl. oz.
Skip the broadcast spreader entirely — that’s the pitch here. This liquid concentrate attaches to a garden hose, so application is a matter of walking the lawn with water pressure doing the mixing, no granules to calibrate or sweep off the driveway. Compared with Simple Lawn Solutions’ 16-4-8 liquid fertilizer in this roundup, the practical difference is the reusable hose-end sprayer with a translucent bottle, letting you see exactly how much product remains instead of guessing mid-application. The 29-0-3 formula pushes fast nitrogen-driven green-up on any grass type. Two honest drawbacks: refills are sold separately, which changes the long-term cost math, and the lawn needs to dry before kids and pets go back on it — a small wait, but a rule that matters for busy households. Coverage also runs shorter per dollar than granular bags like Turf Builder Lawn Food 12.5 lbs.
Pros:- No spreader needed — attaches directly to a garden hose
- Reusable applicator reduces plastic waste over time
- Translucent bottle shows remaining product during application
- Kids and pets can return once the spray dries, when used as directed
Cons:- Refill bottles sold separately, adding ongoing cost
- Requires full drying before lawn re-entry
- Less economical per square foot than granular alternatives
Best for: Homeowners without a spreader who want quick, mess-free feeding with a hose
Not ideal for: Budget-focused buyers — refill bottles sold separately add recurring cost versus granular bags
- Volume:32 fl. oz.
- NPK Ratio:29-0-3
- Application Method:Hose-end sprayer
- Applicator:Reusable
- Grass Type:Any grass type
Our verdict“This pick makes the most sense for spreader-free households that value convenience over cost per application.”
Scotts Turf Builder Lawn Food, 12.5 lbs
When you want one bag that works whenever you remember to fertilize, this is the workhorse. The 12.5 lb Turf Builder Lawn Food feeds all grass types in spring, summer, or fall, on wet or dry turf — a flexibility the seasonal GreenView Fall Lawn Food and the fall-only WinterGuard simply don’t offer. It skips the specializations: no weed control like the Triple Action Built for Seeding, no insect protection like the SummerGuard, just nitrogen-driven feeding and root development that improves water and nutrient uptake over time. That simplicity is its strength and its limitation. You’ll want a broadcast spreader for even coverage (hand-spreading leads to stripes), and watering after application speeds results, which means planning around your sprinkler or the forecast. At 5,000 sq. ft. per bag, mid-size lawns may need two.
Pros:- Works on all grass types in spring, summer, or fall
- Builds deep roots for better water and nutrient absorption
- Can be applied to wet or dry lawns
- Pesticide-free formula safe for a straightforward feeding routine
Cons:- No weed or insect control — requires separate products for those problems
- Spreader recommended for even application
- 5,000 sq. ft. coverage means multi-bag purchases for larger lawns
Best for: Homeowners who want a single, flexible fertilizer they can apply in any season without keeping multiple products on hand
Not ideal for: Buyers who want combined weed or insect control — this is feeding only, so you’ll need separate products
- Brand:Scotts
- Product Type:Lawn Food
- Weight:12.5 lbs
- Coverage Area:5,000 sq. ft.
- Grass Type:All grass types
- Application:Wet or dry lawn
- Seasons:Spring, Summer, Fall
- Formula:Pesticide-free
Our verdict“This is the dependable default for anyone who wants straightforward, season-flexible feeding and nothing else to think about.”
O.M. Scott & Sons Natural Grass Food, 12.72 lbs
No added artificial ingredients or pesticides sets this apart for buyers who want a natural grass fertilizer and can follow the label’s directions for use around children and pets. It feeds for up to 10 weeks and works across grass types, making it a flexible pick for routine lawn care. Compared with Scotts Turf Builder Lawn Food, 12.5 lbs, this formula highlights its ingredient profile and recyclable paper bag rather than broad coverage: one bag treats up to 2,000 sq. ft. That smaller area can mean buying multiple bags for a larger lawn. You’ll also need to water after spreading it, and ongoing feeding calls for repeat applications every 8 to 10 weeks. I’d choose it for modest lawns where the natural formula is the priority.
Pros:- Feeds grass for up to 10 weeks
- Suitable for all grass types
- No added artificial ingredients or pesticides
- Recyclable paper bag
Cons:- Covers up to 2,000 sq. ft. per bag
- Requires watering after application for best results
- Ongoing feeding requires applications every 8 to 10 weeks
Best for: Owners of smaller lawns who want a natural fertilizer without added artificial ingredients or pesticides.
Not ideal for: People maintaining large lawns who want fewer applications or a product that does not require watering after spreading.
- Product type:Natural lawn fertilizer
- Weight:12.72 lbs
- Coverage:Up to 2,000 sq. ft.
- Feeding duration:Up to 10 weeks
- Grass compatibility:All grass types
- Application:Apply with a spreader and water afterward
- Use frequency:Every 8 to 10 weeks, up to 4 times per year
- Packaging:Recyclable paper bag
Our verdict“Choose this for a smaller lawn when a natural formula matters more than broad coverage.”
Scotts Turf Builder Starter Food for New Grass, 15 lbs.
When the job is germinating seed, reseeding bare patches, or establishing sod, a starter formula is a more targeted choice than a general lawn food. Its 24-25-4 NPK ratio is formulated for new grass, and the product data reports that new grass grows 70% thicker and 35% quicker on average than unfed lawns. A 15 lb. bag covers up to 5,000 sq. ft., giving it more reach than O.M. Scott & Sons Natural Grass Food, though the two serve different stages of lawn care. The key limitation is that this is for establishment, not regular feeding of a mature lawn. I’d keep it in the shed for planting or repair projects and use a maintenance fertilizer once the lawn is established.
Pros:- Formulated for seed, sod, sprigs, and plugs
- 24-25-4 NPK ratio designed for new grass
- Covers up to 5,000 sq. ft. per bag
- Suitable for all grass types
Cons:- Intended for new grass establishment rather than routine lawn maintenance
- The product data does not specify feeding duration or application frequency
Best for: Homeowners seeding a new lawn, overseeding thin grass, or installing sod, sprigs, or plugs.
Not ideal for: People feeding an established lawn who want one fertilizer for routine maintenance.
- Product type:Starter fertilizer
- NPK ratio:24-25-4
- Bag weight:15 lbs
- Coverage:Up to 5,000 sq. ft.
- Grass compatibility:All grass types
- Intended use:New lawns, reseeding, sod, sprigs, and plugs
- Average growth claim:70% thicker and 35% quicker new grass versus unfed lawns
Our verdict“Pick this for planting or repairing grass, then switch to a maintenance fertilizer after establishment.”
Simple Lawn Solutions Advanced 16-4-8 Balanced NPK Liquid Lawn Fertilizer, 32 oz
This 16-4-8 liquid formula suits lawn owners who prefer a spray application and want nitrogen, phosphorus, and potassium in a balanced blend. Seaweed and fish are included to support nutrient uptake, root development, and stress tolerance, while the formula is intended for spring and summer use on all grass types. Compared with Scotts Turf Builder Liquid Lawn Food, 32 fl. oz., this option makes its 16-4-8 analysis and seaweed-and-fish ingredients explicit; the provided data does not establish a coverage advantage over that alternative. The tradeoff is that the 32 oz. container may be a less practical fit for large lawns, and repeated applications may be needed to sustain results. I’d favor it for seasonal care where spray convenience matters more than a single application covering a broad area.
Pros:- 16-4-8 formula supplies nitrogen, phosphorus, and potassium
- Includes seaweed and fish
- Suitable for all grass types
- Spray format offers a convenient application option
Cons:- Primarily intended for spring and summer
- May need repeated applications for sustained results
- Coverage area is not specified in the supplied product data
Best for: Owners of small or medium lawns who want a spring and summer spray fertilizer with a stated NPK ratio.
Not ideal for: People seeking a fall-specific feed or a product with a clearly stated large coverage area and long feeding interval.
- Product type:Liquid lawn fertilizer
- NPK ratio:16-4-8
- Nitrogen:16%
- Phosphorus:4%
- Potassium:8%
- Volume:32 oz
- Season:Spring and summer
- Grass compatibility:All grass types
- Additional ingredients:Seaweed and fish
Our verdict“Choose this for convenient spring and summer feeding when its stated 16-4-8 blend fits your lawn-care plan.”
Scotts Turf Builder Weed & Feed3, 14.29 lbs
For grass lawns that also need weed control, this combines fertilizer with treatment for over 50 listed weeds, including dandelion, clover, and plantain. WeedGrip Technology is intended to target visible and hidden weeds, while feeding helps thicken grass and crowd out future weeds. A bag covers up to 5,000 sq. ft., matching the stated coverage of Scotts Turf Builder Starter Food for New Grass, 15 lbs., but this product is for an existing lawn rather than establishing new grass. The fit has firm limits: it is not for several grass types, including St. Augustinegrass, bentgrass, carpetgrass, dichondra, and lippia. Application also requires temperatures between 60°F and 90°F, a 24-hour period without watering or rain, and keeping people and pets off until dust settles. It makes sense when the lawn type and weather window suit the label.
Pros:- Controls over 50 listed weeds, including dandelion and clover
- Combines weed treatment with lawn fertilizer
- Covers up to 5,000 sq. ft.
- WeedGrip Technology targets visible and hidden weeds
Cons:- Not suitable for St. Augustinegrass, dichondra, lippia, carpetgrass, or bentgrass
- Requires daytime temperatures between 60°F and 90°F
- Lawn must stay dry for 24 hours, and people and pets must stay off until dust settles
Best for: Owners of compatible grass lawns with broadleaf weeds who want to feed and treat the lawn in one application.
Not ideal for: People with St. Augustinegrass, bentgrass, carpetgrass, dichondra, or lippia, or those unable to keep the lawn dry after application.
- Product weight:14.29 lbs
- Coverage:5,000 sq. ft.
- Weed control:Over 50 listed weeds, including dandelion, clover, and plantain
- Application temperature:Daytime temperatures between 60°F and 90°F
- Broadcast or rotary spreader setting:3.5
- Drop spreader setting:5
- Not for:St. Augustinegrass, including Floratam; dichondra; lippia; carpetgrass; bentgrass

Scotts Turf Builder WinterGuard Fall Lawn Food, 32.3 lbs
With 12,000 sq. ft. of coverage from one 32.3 lb. bag, this is the lineup’s clear fit for fall feeding across a large lawn. It is designed to help grass recover from summer heat, drought, and activity while building roots ahead of winter. Compared with Scotts Turf Builder WinterGuard Fall Lawn Food, 10 lbs, this larger package covers more ground per bag; the supplied data does not provide a corresponding coverage figure for the smaller product, so I can’t make a direct per-area comparison. This fertilizer is also more season-specific than O.M. Scott & Sons Natural Grass Food, which is described as feeding for up to 10 weeks. If you need a spring or summer feed, WinterGuard is the wrong tool. I’d choose it for a broad lawn when fall timing is the priority.
Pros:- Covers up to 12,000 sq. ft. per bag
- Designed to build strong, deep roots for next spring
- Helps grass recover from summer heat and drought
- Suitable for any grass type
Cons:- Intended specifically for fall application
- The supplied product data does not state NPK ratio or feeding duration
Best for: Owners of large lawns who want a fall application to support recovery and root growth before winter.
Not ideal for: People looking for a year-round fertilizer or a feed for spring and summer lawn care.
- Weight:32.3 lbs
- Coverage:Up to 12,000 sq. ft.
- Application season:Fall
- Application conditions:Apply to wet or dry lawn
- Grass compatibility:Any grass type
- Intended benefit:Builds deep roots and helps lawns recover from summer stress
Our verdict“Pick this for a large lawn that needs its fertilizer application in fall, not for routine feeding throughout the year.”
How We Picked
I evaluated each fertilizer through the lens a homeowner actually faces: what stage is the lawn in, and what season is it. Every product was sorted into a role — all-season feeding, new grass establishment, fall winterization, or quick green-up — and then judged on nutrient analysis, coverage per bag, grass-type compatibility, and ease of application. Products that serve a narrow purpose well (like WinterGuard for fall) were ranked against their seasonal peers, not against all-purpose feeds, because a fall formula and a summer formula solve different problems.
The ranking also weighed cost efficiency per square foot and the tradeoff built into combination products: a weed-and-feed or insect-control formula saves a pass over the lawn but restricts when you can safely apply it. Finally, I favored formulas with broad grass-type compatibility and forgiving application windows, since beginners lose money fast when a product burns turf because conditions were not ideal.
Factors to Consider When Choosing Fertilizer For Grass
Before picking a bag off the shelf, it helps to understand what actually drives results with grass fertilizer — and where homeowners most often go wrong.NPK Ratio and What It Actually Does
Every fertilizer bag shows three numbers, and they tell you the product’s job. Nitrogen (N) drives green, leafy growth, phosphorus (P) builds roots — which is why starter foods carry higher middle numbers — and potassium (K) strengthens the plant against stress, which is why fall winterizers are potassium-heavy. A common mistake is applying a high-nitrogen feed in early spring, which fuels top growth while roots stay weak. The pattern in this roundup is that all-purpose feeds sit near a balanced analysis, while seasonal products lean deliberately one direction. Match the ratio to the season and lawn stage rather than chasing the biggest first number on the bag.
Granular Versus Liquid
Granular fertilizers release nutrients slowly over weeks or months and require a spreader, but they forgive uneven walks across the lawn. Liquids attach to a hose and absorb quickly — often showing color in days — but the feed fades in a few weeks and uneven spraying causes streaking. The mistake I see most often is treating liquid as a full feeding program; it works better as a supplement between granular applications. If you dislike pushing a spreader or have a small lawn, liquid’s convenience wins. If you want to fertilize three or four times a year and be done, granular is the better fit.
Bag Size, Coverage, and the Cost Mistake
Coverage claims on fertilizer bags assume a specific spreader setting and application rate, so buying based on your actual lawn area matters more than bag weight. In this category, small bags (10–15 lbs.) suit urban lawns under 4,000 square feet, while 32–48 lb. bags only make sense if you genuinely cover 10,000–15,000 square feet. The most common waste is buying a large bag for a small lawn and storing opened fertilizer, which absorbs moisture and clumps over winter. Calculate your lawn area once — measure it with a mapping app or pacing — and match the bag to it. Cost per thousand square feet, not sticker price, is the number worth comparing.
Combination Products: Time-Saver or Trap
Weed-and-feed and insect-control formulas tempt you because they solve two problems in one pass. The catch is application windows: weed controls need actively growing weeds and specific temperatures, and some require damp grass so particles stick to leaves. If conditions are wrong, you either waste the herbicide portion or damage nearby plants. Combination products also prevent spot-treating — you broadcast a weed killer across the whole lawn to hit a few dandelions. My guidance: use combinations when your lawn genuinely has the problem everywhere, and stick to straight fertilizer plus targeted treatments when issues are localized.
Grass Type and Regional Fit
Cool-season grasses (fescue, bluegrass, rye) peak in spring and fall and benefit most from fall feeding, while warm-season grasses (Bermuda, St. Augustine, zoysia) want their heaviest feeding in early summer. Most products in this roundup are safe for all grass types, but timing shifts by region — a fall winterizer applied in Florida’s growing season behaves very differently than in Michigan. Check the label’s temperature guidance, because fertilizing a dormant lawn wastes money and feeding during a heat wave can burn turf. When in doubt, feed when the grass is actively growing and skip calendar-based schedules.
Natural Versus Synthetic Formulas
Synthetic fertilizers act fast and cost less per application, while natural options like O.M. Scott & Sons Natural Grass Food feed soil biology and carry lower burn risk, at the price of slower visible results. Neither is universally better — the choice depends on kids and pets on the lawn, proximity to waterways, and how quickly you want green. One caution: natural products often need more frequent application to maintain color, so the per-season cost gap narrows. If you are transitioning from synthetic to natural, expect a greener-but-slower first season. Blending approaches — natural feedings with one synthetic boost — is a reasonable middle path many lawn owners settle on.
Frequently Asked Questions
Should I use starter fertilizer on an established lawn?
You can, but it is usually the wrong tool. Starter formulas like Scotts Turf Builder Starter Food trade fast top-growth for root development and phosphorus, which established lawns need less of — their roots are already developed. On a mature lawn, a balanced all-purpose feed like Scotts Turf Builder Lawn Food produces better color and density. Where starter food does help established turf is after aeration or heavy thatch removal, when roots have been disturbed. If you are overseeding into an existing lawn, starter food is exactly right because it feeds both the new seedlings and the mature grass around them.
Do I really need a separate fall fertilizer?
Fall feeding is arguably the single highest-impact application of the year for cool-season lawns. Products like Scotts WinterGuard and GreenView Fall Lawn Food shift the nutrient balance toward potassium and root storage, which is how grass survives winter and greens up early in spring. Skipping fall fertilizer and doubling up in spring does not produce the same result — spring nitrogen pushes leaf growth, while fall feeding builds the plant. If budget only allows two applications a year, make them late spring and late fall. Warm-season lawns follow a different calendar, with their final feeding coming in late summer rather than late fall.
Is liquid or granular fertilizer better for a beginner?
Granular is more forgiving for most first-timers because a spreader with a set dial controls the rate, and slow release means small errors fade rather than burn. Liquid products concentrate the whole feeding in one hose pass, and walking too fast or spraying unevenly produces visible streaks within a week. That said, liquid wins for very small lawns where storing a spreader feels excessive, and it is hard to beat for a quick green-up before an event. If you start with granular, buy a cheap broadcast spreader and follow the bag’s setting. The mistakes that ruin lawns — over-applying liquid or overlapping granular passes — are both avoidable with a little planning.
Can I apply weed and feed at the same time as grass seed?
Almost never. Standard weed-and-feed products like Scotts Weed & Feed3 contain herbicides that prevent or kill germinating seed, so applying them with new seed wastes both the seed and the fertilizer. The exception in this roundup is Scotts Turf Builder Triple Action Built for Seeding, which is specifically formulated to feed new grass while controlling weeds that seeding usually triggers. If you have already spread a conventional weed-and-feed, the label typically requires waiting several weeks before seeding. The safer sequence is seed first with starter food, establish the grass, then address weeds once the new turf has been mowed two or three times.
How often should I fertilize my lawn?
Most cool-season lawns do well with three to four feedings a year: early spring, late spring, summer (light, only if irrigated), and the important fall application. Warm-season lawns shift that schedule toward late spring through late summer. Slow-release granular products in this lineup feed for six to eight weeks, which sets the natural spacing between applications. The common mistake is under-fertilizing rather than over-fertilizing — sparse feeding produces a thin lawn that invites weeds. Whatever schedule you pick, record the dates and product used, because results improve dramatically once you follow a consistent year-over-year program rather than feeding whenever the lawn looks pale.
Conclusion
The right pick here depends entirely on what your lawn needs this season. For best overall, Scotts Turf Builder Lawn Food (37.5 lbs.) covers any grass type, any feeding window, and a large area — the safest choice for most lawns. For best value, GreenView Fall Lawn Food covers 15,000 square feet per bag, making it the cheapest way to feed a big yard well. For best premium pick, The Andersons Professional PGF Complete with humic acid delivers golf-course-grade nutrition and soil benefits no other option here matches. For beginners, Scotts Turf Builder Liquid Lawn Food eliminates spreader setup and mistakes entirely — just attach and spray. For specific needs: new seed or sod calls for Starter Food for New Grass (size the bag to the project), a tired lawn needing fast color gets Green Max, fall prep points to WinterGuard, and a lawn fighting weeds or insects justifies Weed & Feed3 or SummerGuard. Match the product to the season and lawn stage, and the rest of the decision makes itself.
