Autumn is the defining season for your lawn. The feeding you do now builds the root system that dictates how green and thick your grass is next spring — and one wrong product choice means feeding the weeds right alongside your grass. The trick is landing on a feed-and-weed combo that kills broadleaf weeds while delivering the exact fall-appropriate NPK ratio (high potassium, moderate nitrogen) your lawn needs for winter hardiness. This guide walks through the top-rated fall formulations, from fast-spray weed-and-feed jugs to heavy granule bags that feed for months, so you can pick what matches your yard size, grass type, and patience level.
I’m Rikta — the founder and writer behind Lawn Gear Lab. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The lineup here — from a 48-pound winterizer to a ready-to-spray hose-end bottle — covers every yard size and summer-wear level, so you can find the best feed and weed autumn plan that fits your exact lawn.
Our Picks at a Glance
How To Choose The Best Feed And Weed Autumn Product
A fall feed-and-weed product has a different job than a spring one. You want to stop broadleaf weeds from overwintering while delivering a NPK ratio that encourages root growth, not leafy top growth. Three factors separate the products that work from the ones that waste your weekend.
NPK Ratio and the Fall Shift
In spring you reach for high-nitrogen (the first number) to push green top growth. In autumn you want the second and third numbers higher — phosphorus and especially potassium. The potassium (the last number) strengthens cell walls and helps the grass plant survive winter stress. A fall product like 22-0-10 or 21-0-3 has almost no phosphorus and a moderate potassium kick, aiming for root density and winter hardiness rather than a fast green-up.
Granule vs. Spray Delivery
Granular weed-and-feed products (like the Scotts and The Andersons bags) require a spreader and watering to activate the herbicide on weed leaves. They cover larger areas per bag and feed the soil slowly. Hose-end spray bottles (like the Spectracide) are quicker — you just attach, flip, and spray — but the coverage per bottle is smaller, and the herbicide works through leaf contact only. Granules are better for pre-planned weekend work; sprays fit a mid-week quick hit when you see a patch of clover.
Weed-Kill Spectrum and Grass Safety
Not every fall weed-and-feed kills the same weeds. The Jonathan Green product claims control over 250 broadleaf weeds, while the Scotts WinterGuard covers more than 50 listed weeds including clover and dandelion. Some products are explicit about which grass types they work on — the The Andersons Barricade, for example, lists bahia, bermuda, bluegrass, centipede, fescue, rye, St. Augustine, and zoysia but says do not use on dichondra or carpet grass. Check your grass type and the weed species in your yard before you buy — no product kills everything.

In‑Depth Reviews
1. GreenView Fall Lawn Food
Our pick — over 4.5★ from 550+ verified ratings; the strongest balance of quality and price.
The 48-pound winterizer that feeds all season and jumpstarts spring green-up.
This is the heavyweight of autumn lawn prep. The 22-0-10 formula is built solely for fall — near-zero phosphorus, high potassium — so your grass focuses energy on root depth rather than leaf growth. The GreenSmart Enhanced Efficiency technology inside feeds continuously for up to eight weeks, which means one application in late autumn carries your lawn through winter dormancy. The bag covers a generous 15,000 square feet, making it a strong fit for quarter-acre-plus yards. Buyers report it works as a winterizer and produces a fast green-up in spring after a single fall application.
The fine granule texture spreads easily with a standard rotary or drop spreader, even when the bag is full at 48 pounds. A few owners note that the coverage per application feels denser than what smaller bags deliver, which tracks with the high NPK concentration. This is not a weed-killer — it is a straight fall fertilizer with no herbicide — so you will need a separate weed treatment if your lawn is heavy with dandelion or clover. For pure root-building winter feed, the quality and batch consistency here are why nearly 600 owners rate it a crowd favorite.
GreenView fall feeding
- Continuous feeding for up to 8 weeks with a single application
- 48 lb bag covers 15,000 sq ft — a strong area-to-weight ratio for larger lawns
- High potassium (10) supports winter root hardiness directly
Slow nitrogen release
- Contains no herbicide — existing weeds need a separate weed-and-feed or spot spray
- 48 lb bag is heavy to carry and lift into a spreader hopper
reach for this if: you want a dedicated fall-only winterizer that feeds roots for two months and sets up a fast spring green-up with zero guesswork about NPK ratio.
think twice if: your lawn has an active broadleaf weed problem right now — you will need a second product to tackle those weeds this season.
2. Spectracide Weed & Feed 20-0-0
The hose-end spray that kills broadleaf weeds and feeds in under an hour.
This is the fastest route to knocking out visible weeds while giving your lawn a 20 percent nitrogen (the first number) feed — no spreader, no watering in, no heavy bag. The QuickFlip sprayer attaches to any standard garden hose: you grip, flip the lever, and spray directly onto wet grass. The 32-ounce bottle covers up to 7,500 square feet, which is a solid match for a typical suburban front-and-back lot. Owners mention that weeds begin turning white within days and that the fertilizer effect shows clearly after two to three weeks of rain.
The herbicide targets major broadleaf weeds — dandelion, chickweed, knotweed, plantain, clover, mallow, and purslane — making it a good choice if those are your primary invaders. A common tip from owners: avoid spraying when temperatures climb above 85°F to prevent off-target damage. The lingering salty smell is a minor annoyance that fades after a few days. Keep pets and people off the lawn until the spray dries completely.
Spectracide weed control
- Ready-to-spray — no measuring, no spreader, just connect to a hose and flip the lever
- Kills 8+ named broadleaf weed species while feeding with 20% nitrogen
- Light 2.8 lb bottle — dramatically easier to handle than a bag of granules
High nitrogen burn
- No phosphorus or potassium — this is a nitrogen-only feed, not a complete fall fertilizer
- Some owners find the weed control less effective on tougher perennial weeds like violets
grab it for: a quick weekend weed hit on a lawn that already has decent density — the spray is faster than spreading granules and requires no cleanup.
skip it if: you are looking for a balanced fall NPK (this has 20-0-0 — zero potassium for winter hardiness) or if your yard is bigger than about 7,500 square feet per bottle.
3. Ultimate 3-18-18 NPK
The high-phosphorus, high-potassium liquid that targets roots instead of leaves.
Most fall products push potassium (the last number) with moderate nitrogen. This one does something different: it delivers 18 percent phosphorus and 18 percent potassium with just 3 percent nitrogen. The 3-18-18 ratio is essentially the opposite of a spring lawn food — it is designed for root development and stress tolerance rather than green top growth. The liquid concentrate comes with a ready-to-use hose-end sprayer that mixes the perfect ratio automatically and covers up to 3,200 square feet per bottle. Customers note stronger root systems and improved turf vigor, especially on lawns that show phosphorus deficiency.
This product works on all common grass types including Bermuda, St. Augustine, Zoysia, and bluegrass. The liquid formulation makes it easy to spot-treat thinner areas or apply evenly across the whole lawn. A few reviewers point out the results are subtle — no dramatic greening — which is actually a good sign for a fall root feeder. One owner mentioned it requires thorough watering after application for best results. If your soil test shows low phosphorus, this is the most direct way to correct it during autumn prep.
Ultimate low nitrogen
- High phosphorus (18) and potassium (18) directly support root development and winter hardiness
- Ready-to-use hose-end sprayer applies the correct ratio — no mixing
- Works on every common grass type from Bermuda to bluegrass
No weed control
- Very low nitrogen means little to no greening — do not expect a visual lawn improvement
- Some users saw no visible difference compared to a standard balanced fertilizer
ideal for: lawns that need a phosphorus boost for root establishment — especially new sod or overseeded areas going into winter.
not the one if: you want a visible green-up from your fall application or if your lawn is already phosphorus-rich (a soil test will tell you).
4. Scotts Turf Builder Weed and Feed
The granular weed-and-feed that clobbers dandelion and clover in under a week.
This is the most widely bought weed-and-feed on the market for a reason — you get a high-nitrogen lawn fertilizer plus a contact herbicide that targets broadleaf weeds. The 14.3-pound bag covers 5,000 square feet using a standard spreader. Scotts uses what they call Weedgrip Technology, which the company says grips both visible weeds and the ones you have not spotted yet. In practice, shoppers say that dandelion, plantain, and dollar weed curl up within two days and are gone in about a week. The grass simultaneously thickens up, which crowds out new weeds naturally.
A significant caution: this product works best when applied to wet weeds, and you should not water for two to three days afterward to give the herbicide time to absorb. Some owners found it ineffective on crabgrass and clover despite working well on dandelion. Avoid walking on treated areas for at least 24 hours to prevent burn spots. The active ingredients (2,4-D and mecoprop) are standard for this category, but the conventional formula means this is not a low-chemical option.
Scotts quick greening
- Two-day visual weed die-off on dandelion, plantain, and dollar weed per owner reports
- Granules feed the soil while the herbicide attacks existing weeds in one pass
- Scotts brand reliability with tens of thousands of positive reviews backing it
Short-term results
- Weaker on crabgrass and clover — some buyers report no effect on those species
- Requires precise application timing (wet grass, no rain for 2-3 days) for full effectiveness
choose it when: dandelion is your primary weed and you want a granular product that feeds and kills in a single spreader pass across up to 5,000 square feet.
look elsewhere if: your lawn is dominated by crabgrass or clover — this product has been reported as weak against those two species.
5. Jonathan Green Green-Up Weed & Feed
The fine-particle granule that claims control over 250 weed species plus three months of feeding.
Jonathan Green targets the homeowner who does not want to memorize weed names. The 21-0-3 formula delivers a gradual, consistent nutrient release for up to three months — long enough to cover late autumn through early winter. The herbicide claims control over more than 250 broadleaf weeds including dandelion, chickweed, clover, wild onion, thistle, and poison ivy, which is a wider spectrum than most competitors list. The fine particle size is designed to feed the grass longer while weeds gradually disappear. A 15-pound bag covers up to 5,000 square feet.
Owners mention their yard looks the best on the street after one application, praising the greening effect. But the weed control gets mixed reports: some owners say the grass greened up nicely while the weeds also greened up, and others report it did not kill the weeds it claimed to, even with a heavier application. This split in owner experiences means the product works best on a lawn with a modest weed load, not a full infestation. Use a rotary, drop, or hand-held spreader; apply in late spring or early fall when weeds are actively growing.
Jonathan Green organic
- Controls over 250 broadleaf weed species on paper — the widest spectrum in this guide
- Gradual nutrient release feeds the lawn for up to 3 months from a single application
- Fine particle size ensures even coverage and consistent distribution through a spreader
Higher price point
- Weed control is inconsistent in practice — some customers note zero weed kill despite following directions
- The 15 lb bag is small relative to its coverage claim, and some units arrive with clumps that are hard to break apart
best for: a lawn with light to moderate weeds where the main goal is feeding through early winter and you want a broad-spectrum herbicide list.
think twice if: you have a heavy weed infestation — some reviewers point out the herbicide component did not perform as claimed on established weeds.
6. The Andersons Premium Weed and Feed 24-0-16
The iron-enriched granule that gives you both quick and slow nitrogen release.
The Andersons brings a tightly engineered option: 24-0-16 with both quick-release nitrogen (for an immediate green response) and slow-release nitrogen (for up to three months of sustained feeding). The high potassium (16) is exactly what a fall lawn needs for winter root storage. The bag also contains iron, which produces a deep green color without relying solely on nitrogen. This 18-pound bag covers 5,000 square feet. The herbicide component controls existing dandelion and more than 250 broadleaf weeds.
Owners who switched from Scotts report seeing a noticeable difference in grass growth and thickness after two applications. The granules are small — a characteristic of The Andersons’ DG (dispersible granule) technology — which means they dissolve quickly when watered in and deliver the herbicide directly into the soil. A few shoppers say that the weed control was less effective on their specific weed mix, with some requiring a third application. Not for sale in New York, Florida, California, or Indiana. Works on bahia, bermuda, bluegrass, centipede, fescue, rye, St. Augustine, and zoysia.
Andersons even spread
- Dual-release nitrogen gives both immediate greening and extended feeding over 3 months
- 24-0-16 ratio is the highest potassium count in this guide, ideal for winter root development
- Contains iron for deep green color without overloading nitrogen
Limited weed types
- Not available in NY, FL, CA, or IN due to state regulations
- Weed control results vary — some buyers report minimal effect on their weed mix even after two applications
reach for it if: you want a single fall product that greens up quickly, feeds for months, and provides iron-enhanced color without a second application.
watch out for: state shipping restrictions and the possibility that your specific weeds may require a follow-up treatment.
7. Scotts Turf Builder WinterGuard Fall Weed & Feed
The 33.8-pound fall bag built for larger lawns with stubborn clover and dandelion.
This is the same Scotts brand that dominates spring weed-and-feed but reformulated specifically for autumn. The WinterGuard label means the nitrogen-to-potassium balance is tilted toward winter preparation rather than rapid green-up. The bag kills more than 50 listed weeds (including clover, dandelion, plantain, morningglory, chicory, evening primrose, and purslane) while feeding the grass. A single 33.8-pound bag covers 12,000 square feet — ideal for third-acre plus properties. Apply to a wet lawn when temperatures stay between 60°F and 90°F for best results.
Buyers consistently report that the product knocks out clover within weeks, and many describe it as their go-to for dandelion control every spring and fall. The large bag size means you are not buying multiple units for a big yard. A common owner tip: if you see the lawn turn brown in patches after application, that is weed die-off, not grass damage — reseeding those bare spots after treatment is the recommended follow-up. Some owners caution that inexperienced spreader use can leave dead streaks where the granules concentrated on one pass.
WinterGuard cold prep
- Large 33.8 lb bag covers 12,000 sq ft — fewer refills for big lawns compared to smaller bags
- Kills over 50 listed weeds including tough clover and morningglory per the manufacturer
- Consistent Scotts brand quality with thousands of positive reviews across multiple seasons
Not for spring use
- Inexperienced spreader handling can leave dead streaks on the lawn; walk in a consistent pattern
- Weed control spectrum (50+ weeds) is narrower than some competitors that claim 250+ species
best for: homeowners with 10,000+ square foot lawns who want a single-bag weed-and-feed treatment effective on clover and dandelion through the fall window.
not ideal if: your weed problem is very broad (more than 50 species) or if you prefer a smaller bag for a compact yard.
8. The Andersons Barricade 18-0-4
The professional-grade pre-emergent that stops crabgrass before it starts.
This is not your standard weed-and-feed — it is a preventive product that stops weeds from germinating rather than killing existing ones. The 18-0-4 fertilizer comes loaded with 0.426 percent prodiamine, a pre-emergent herbicide that prevents 30 grass and broadleaf weeds including crabgrass, poa annua (annual bluegrass), goosegrass, and henbit. The 40-pound bag covers a substantial 10,000 square feet. The patented DG (dispersible granule) technology means the granules dissolve rapidly when you water them in, moving the prodiamine directly into the soil where it forms a barrier against germinating seeds.
Best applied in early spring and early fall, this product is not designed to eliminate existing weeds — use it as a component of a full-season program (spring pre-emergent, fall feeding). Owners mention the best results on zoysia and bermuda lawns in warmer states, with multiple mowings and zero weed breakthrough after three seasons. The value-for-money score is mixed: some consider it overpriced compared to store-brand alternatives, while others find it worth every cent for the crabgrass prevention alone.
Barricade pre-emergent
- Professional-grade prodiamine (0.426%) prevents 30 weed types including crabgrass and poa annua
- DG Technology ensures rapid soil penetration when watered — no granules sitting on top of turf
- 40 lb bag covers 10,000 sq ft, suitable for larger lawns seeking season-long prevention
No post-emergent
- Will not kill existing weeds — this is a preventive, not a curative product
- Some owners find it overpriced compared to other pre-emergent blends at the same coverage
pick this if: you follow a planned lawn program (spring pre-emergent / fall feed) and want to stop crabgrass before it appears with a single large-bag application.
avoid it if: you need to kill existing weeds now — this product prevents, it does not eliminate.
9. The Andersons Surge 16-0-9
The professional-grade four-way weed killer that targets over 250 species across 16,000 square feet.
If you have a half-acre lawn overrun with broadleaf weeds and you want to hit them hard with a single pass, this is the bag. The 16-0-9 formula (16% nitrogen, 0% phosphorus, 9% potassium) includes a four-way herbicide combination that eliminates more than 250 common broadleaf weeds including dandelion, clover, chickweed, and plantain. The 40-pound bag covers up to 16,000 square feet — the largest coverage in this guide — making it the right choice for large lots, farmhouse lawns, or rural properties. The fine granule particles provide dense coverage per square inch, and the product is designed to deliver superior performance even in the cooler temperatures of spring and fall.
Owners who switched from Scotts report seeing killed weeds faster with the Andersons Surge. Some note it eliminated creeping charlie (ground ivy) after a single season — a weed many pre-emergents miss. However, the effectiveness score is mixed among reviewers; while some report excellent weed kill, others say the product performed no better than cheaper alternatives. The product is not for use on Floratam St. Augustine grass, dichondra, carpetgrass, or creeping bentgrass. Not sold in New Hampshire or Washington state.
Surge fast growth
- Largest per-bag coverage in this guide — 16,000 sq ft from a single 40 lb bag
- Four-way herbicide targets over 250 weed species including tough creeping charlie
- Performs in lower fall temperatures where some herbicides lose effectiveness
High nitrogen risk
- Weed control results are not universal — some owners see no difference from cheaper brands
- Not for Floratam St. Augustine or several other grass types; check compatibility before buying
ideal for: large-lot owners who want professional-grade weed kill with maximum per-bag coverage and do not want to treat the same weeds twice.
watch out for: grass-type restrictions (no Floratam St. Augustine, dichondra, or carpetgrass) and the possibility that the weed control may not outperform a budget product on your specific weed mix.
Understanding the Specs
NPK Ratio — the Three Numbers
The three numbers on a fertilizer bag stand for nitrogen (N, leaf growth), phosphorus (P, root development), and potassium (K, winter hardiness and stress tolerance). For fall, you want the last number (potassium) to be relatively high — look for something like 22-0-10 or 24-0-16. The phosphorus (middle number) is often zero or very low in autumn products because fall lawns do not need a phosphorus boost unless a soil test shows a deficiency. Products that list 20-0-0 are nitrogen-only — they feed the green color but do nothing for root depth or winter survival.
Weed Control — Active Ingredients and Spectrum
The herbicide part of a weed-and-feed product is measured in its active ingredient percentage and the number of weed species it controls. A product like the Jonathan Green claims control over more than 250 broadleaf weeds on paper; the Scotts WinterGuard lists over 50. The actual effectiveness depends on the specific weed species in your lawn, the application timing, and whether the weed is actively growing. A product with a four-way herbicide blend (multiple active ingredients) generally covers a wider spectrum than a single-ingredient formula. Pre-emergents like prodiamine prevent weeds before they germinate; they do not kill existing weeds.
