If your lawn has gone dotted with yellow and you want the weeds gone without wrecking the grass around them, the short answer is this: you need a selective broadleaf herbicide — a spray that kills dandelions while leaving your turf alone — not a total-vegetation killer that wipes out everything green. The picks below run from concentrates you mix in a pump sprayer to hose-end bottles that clip onto a garden hose.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. 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.
A selective formula works by targeting the broadleaf structure of plants like dandelions while the fine blades of grass shrug it off. Get that distinction wrong and you trade dandelions for a bald patch. Below you will find the strongest dandelion killer for grass options, ranked by how well they clear weeds without harming your turf.
Our Picks at a Glance
How To Choose The Best Dandelion Killer for Grass
The mistake most people make is grabbing a jug of total-vegetation killer because it is cheap and looks strong. That kind of product does not care what it lands on, so it wipes grass just as fast as weeds. What you want instead is a selective broadleaf herbicide, which is built to attack the wide leaves of a dandelion while the narrow blades of lawn grass pass through unharmed. Every product below is a selective broadleaf herbicide.
Selective versus total-kill: the one distinction that matters
A selective formula works on broadleaf plants and leaves grassy turf alive when you follow the label. A non-selective product like glyphosate kills everything green it touches. If your goal is a green lawn with no dandelions, you always want the selective type — and you want to keep it away from flowers and shrubs, since a broadleaf killer treats those as weeds too.
Concentrate or ready-to-spray
Concentrates are the better value on larger lawns because you mix only what you need, one batch at a time, and the bottle stretches far. Ready-to-spray versions clip onto a garden hose and cover a set area with no mixing at all, which suits a small yard or someone who just wants to walk and spray. The trade-off is no control over mix strength.
Time it right for a clean kill
Broadleaf weeds die best when they are young and actively growing, so spring and fall are the windows to target. Spray when rain is not due for a few hours, and avoid a windy day so the mist does not drift onto plants you want to keep. Some formulas let you reseed shortly after, which matters if bare spots are part of your plan.

In‑Depth Reviews
1. GORDON’S Amine 400 2,4-D Weed Killer, 1 Quart – 8141082
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
A squat quart of concentrate that stretches across a full acre of lawn.
Its draw is the coverage: 43,560 square feet from one quart. One 32-fluid-ounce quart of this 2,4-D concentrate treats 43,560 square feet — that is a full acre from a bottle you can hold in one hand. Compare it to the GORDON’S Trimec further down, which covers 8000 sq ft from the same quart, and this is the one to reach for when your lawn is measured in acres rather than patches. It is a selective broadleaf herbicide, so it attacks dandelions and creeping charlie while your grass keeps growing.
In use, this is a mix-it-yourself formula: you measure the concentrate into a pump sprayer with water and spot-treat the weeds you can see. Owners describe broadleaf weeds, creeping charlie, dandelions, and even grassy weeds going down within days, with no dead spots left in the lawn. It handles woody and stubborn plants too — Canada thistle and sagebrush both get knocked back, and it does not harm adjacent grass, which matters when your spray can drift toward a neighbor’s yard.
The trade-off is mixing a stronger concentrate by hand. You have to measure carefully and it is a stronger chemical than a ready-to-use wand, so it earns its keep on a big yard but punishes sloppy mixing. The AMINE 400 is also a narrower tool than a three-way blend; for the widest spread of weeds you may want a formula with more actives working at once.
What earns its place
- A 32-fluid-ounce quart covers 43,560 square feet — a whole acre of lawn
- Selective formula leaves grass standing while broadleaf weeds die
- Works on dandelions, creeping charlie, thistle, and woody plants
Where it asks more of you
- You mix and measure the concentrate yourself, so accuracy matters
- Single active ingredient is narrower than a three-way blend
Reach for this if: you have a big lawn and want the most coverage from each bottle of selective broadleaf killer.
Look elsewhere if: you would rather not mix concentrate and want a wand you simply point and spray.
2. GORDON’S Trimec® Lawn Weed Killer
The three-way blend that lawn technicians trust, mixed for smaller yards.
This is the pick for anyone tending a modest lawn who wants the broad-spectrum punch of a professional-style Trimec blend. It is lighter to handle than the Amine 400 at 16 ounces versus 8 ounces, and it covers 8000 sq ft from its 32-fluid-ounce bottle. Trimec combines more than one active ingredient, which is why it reaches a wider range of broadleaf weeds — including creeping charlie, clover, and dandelions — than a single-active formula.
What owners single out is how fast it lands. Dandelions and broadleaf weeds brown and die within a day or two on Zoysia, with no grass damage when you follow the label. It also handles creeping charlie, a weed that laughs off weaker sprays. The recurring caution is value and patience: some find it pricey for the coverage, and it does take around four days on tougher dandelions, with clover sometimes shrugging it off. The bottle carries a soft limit of two uses per season, so pairing it with a spring pre-emergent keeps you from leaning on it too hard.
Zoysia-ready: it clears broadleaf weeds on Zoysia within a day and leaves the grass intact, which is the exact balance most lawn owners are chasing.
The catch: coverage tops out at 8000 sq ft, so a large property will burn through bottles fast, and clover is not guaranteed to go.
Suits you when: your lawn is small to mid-sized and you want a proven multi-active blend that treats creeping charlie and dandelions.
Think twice if: you expect it to clear clover or you are spraying acres at a time.
3. Ortho WeedClear Lawn Weed Killer Ready-to-Use with Comfort Wand, 1 gal.
Grab the wand, squeeze, and point — no mixing, no pump sprayer, no fuss.
If you have never sprayed a lawn before, this is the gentlest way to start. The battery-powered Comfort Wand lets you aim directly at each weed with a squeeze of the trigger, and the ready-to-use liquid needs no measuring at all. One gallon treats up to 20,480 square feet, and the label lists the grasses it is safe on — Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass, and Zoysiagrass — so you can check your lawn against the list before you start. It kills crabgrass, dandelion, clover, chickweed, and creeping charlie down to the root with one application.
Owners spot-treat dandelions and weeds after mowing and see browning by the second day, with the weeds fully dead inside about two weeks. The wand is the real star — the two nozzle settings let you switch spray patterns without swapping tips. When the whole bottle disappeared for one owner and the weeds kept growing, that is the reminder that spot sprays still need even coverage and the right timing.
Where it earns its keep is convenience, not brute force. The wand makes it easy to hit a weed precisely without soaking a whole section, but on stubborn crabgrass you may need repeat passes. At 4.1 stars across 426 ratings it is a strong, simple starter tool for a lawn with scattered weeds rather than a solid dandelion field.
simple to use for spot work: the Comfort Wand and its two spray settings let you dodge grass and soak only the weeds you are aiming at.
Know before you spray: some users find crabgrass needs more than one application, and the tool is built for spot-treating rather than blanketing acreage.
Best if: you want to skip mixing entirely and spot-treat visible weeds with a precise, battery-powered wand.
Skip if: your whole lawn is a dandelion field and you would rather spray the lot in one pass.
4. Spectracide Large Plot Weed Stop for Lawns Concentrate, 1 Gal
A full gallon of concentrate built for lawns you measure in fractions of an acre.
The gallon size is where the value lives. This is 128 fluid ounces of concentrate — four times the 32 fluid ounces you get in the GORDON’S Trimec bottle — and it treats up to 32,000 square feet of Northern grasses or 42,500 square feet of Southern grasses. It kills more than 200 types of weeds down to the root, listing dandelion, chickweed, and clover by name, and it is rainproof within about six hours of application, so a passing shower will not wash the work away.
Owners lean on this for big jobs. One ranch owner cleared noxious spurge across three acres in Colorado, working about an acre a morning with a backpack sprayer. Others report it mixes easily, spreads well, and leaves the lawn healthy. On the flip side, the results are not always instant — a few users found it slow and needed two or three passes on the toughest rosette and foxtail weeds — so this is a formula that rewards patience over a snap kill. The label’s coverage claim is what makes it a smart buy for a sprawling yard.
The case for a gallon
- 128 fluid ounces treats up to 32,000 sq ft of Northern grass
- Kills more than 200 weed types down to the root
- Rainproof in about six hours after spraying
The slow edge
- Some tough weeds need two or three applications
- Nine-pound jug is heavier to carry and mix than a quart bottle
A solid fit when: you have a large property and want the most coverage per bottle of ready-mixed concentrate.
Consider passing if: you only have a small patch and want quick, one-and-done results.
5. Fertilome (10524) Weed Free Zone Broadleaf Weed Killer Concentrate, 16 oz
The small-bottle specialist built to hit creeping charlie hard on cool and warm turf.
What defines this pick is its Triclopyr plus Clopyralid formula, and it is the standout for cool-season and warm-season lawns that need to clear more than 80 broadleaf weeds. It is safe on Kentucky Bluegrass, Bermudagrass, Bahiagrass, Zoysiagrass, and more, and the rapid formula shows evidence of injury within hours of application. On creeping charlie in particular it has a reputation as the one that finally works.
Owners applying it in a pump sprayer report night-and-day results comparing a treated side yard to an untreated one after about a week. One Bermuda-lawn user saw weeds turning yellow within two days — and unlike some stronger bleachers, it does not whiten the grass the way Tenacity can, so your lawn keeps its color. The 16-ounce concentrate also offers a lot of treatments; at a couple of ounces per gallon it goes a long way.
The trade-off is that the coverage spec is listed simply as “Full,” so this bottle does not hand you a clean square-foot figure to plan against, and a couple of dandelion duds show up in reviews. It also is not a seedling-safe formula — it kills young grass along with the weeds — so it is a lawn-tender’s tool, not something you spray while overseeding.
Where it shines: creeping charlie and a broad sweep of 80+ broadleaf weeds on a range of turf types, with visible injury within hours.
Keep in mind: coverage is not stated as a square-foot number, and it cannot go down while you are seeding because it kills seedlings.
Worth grabbing for: tough customers like creeping charlie on an established cool or warm-season lawn.
Not your bottle if: you are seeding new grass or you want a specific coverage figure to plan the job.
6. Ike’s Dandelion Destroyer Lawn Weed Killer – Kills Weeds Not Grass, Three-Way Herbicide – 32 oz
A named-for-the-job blend that stacks three actives into one bottle.
This one does exactly what its name says, and the formula explains why. It stacks 2,4-D at 30.9%, MCPA at 8.23%, and Dicamba at 2.77% — three selective herbicides working together — into a low-odor concentrate. That triple blend lets it reach a long list of troublesome weeds: dandelion, chickweed, clover, ground ivy, morning glory, pigweed, plantain, poison ivy, ragweed, spurge, and wild garlic among them. It is designed for lawns with cool-season and selected warm-season grasses.
The application math is easy to work with: mix 0.75 to 1.5 fluid ounces per gallon of water to treat 1,000 square feet, so a single bottle covers a lot of ground for spot work. Owners who mixed it as directed and sprayed the dandelions directly saw wilting within a few days and a yard that looked great after a second pass. It plays well in a tank mix too, pairing with Quinclorac for the stubborn stuff.
The honest limit is patience. The die-off takes three to seven days — slower than a Roundup-style kill — and dandelions can return every four to six weeks, so a pre-emergent in spring keeps the pressure down. A few owners who expected a one-shot fix were left disappointed; treat it as a season-long partner rather than a one-time magic bullet.
Why the three-way mix lands
- Three actives — 2,4-D, MCPA, and Dicamba — in one low-odor formula
- Controls dandelion, clover, ground ivy, spurge, pigweed, and more
- Simple 0.75 to 1.5 fl oz per gallon rate for 1,000 sq ft
What to plan around
- Die-off takes three to seven days, not hours
- Dandelions can return every four to six weeks without a pre-emergent
The pick for you if: you want a broad three-way blend for dandelions and a long list of other broadleaf weeds.
Think twice if: you need a same-day knock-down and will not commit to repeat treatments.
7. Roundup For Lawns3 Ready-To-Spray (Northern), 32 oz.
Clip it to the hose and walk the lawn — no pump, no mixing, no measuring cups.
The whole attraction here is the sprayer. This 32-fluid-ounce bottle connects straight to your garden hose for a broadcast application across up to 5,000 square feet, and it starts working immediately — rainproof in as little as three hours. The formula kills over 250 weeds including crabgrass, dandelion, clover, and yellow nutsedge, and it is labeled for Northern grasses like Kentucky bluegrass, perennial ryegrass, fescue, bermudagrass, buffalograss, and zoysiagrass without harming the lawn.
When it works, it works cleanly. Owners in the Seattle area with irrigation saw one application wipe out all their dandelions and clover inside one to two weeks with the grass untouched. Others noted dandelions wilting by the first day or two. But the results genuinely split — some report creeping charlie browning while clover only gets stressed and crabgrass shrugs it off entirely. A few also hit a leaking hose connection with no way to fix it.
The lesson for a buyer is to know your target. For dandelions and clover on a northern lawn, the hose-end bottle is about as easy as it gets; for crabgrass and stubborn broadleaf holdouts, plan on a dedicated follow-up. It is one of the handiest broadcast tools in this lineup, as long as you are realistic about which weeds it dominates.
Set-and-spray simplicity: the hose-end applicator covers 5,000 sq ft and starts working immediately, rainproof in three hours.
The split: it is near-perfect on dandelions and clover for some lawns, while others find crabgrass and tough weeds barely move.
An ideal match if: you want to blanket a northern lawn by hose with no mixing and clean up dandelions and clover fast.
Look elsewhere if: crabgrass is your main enemy or you want full control over the mix strength.
8. SpeedZone EW Lawn Weed Killer
Cold-weather power that shows weeds your intent within hours of spraying.
Speed is the story with SpeedZone EW, and it earns the claim in cool conditions where a lot of sprays stall. It controls more than 90 listed weeds — white clover, dandelion, ground ivy, spurge, goosegrass, and nimblewill among them — with visible effects within hours. It is rainfast in as little as three hours and lets you reseed in as little as seven days, which is far sooner than most broadleaf killers allow. The label covers Kentucky bluegrass, perennial ryegrass, tall fescue, Bermudagrass, and zoysiagrass.
Owners see the difference fast. One report describes the weeds wilting within about 24 hours, and another saw a big change after a single application with everything gone by the third. It handles clover and broadleaf weeds on tall fescue lawns equally well. The 20-fluid-ounce bottle mixes at 1.5 fluid ounces per half to one gallon for 1,000 square feet on cool-season grass, so you measure carefully but get a lot of treatments from it.
The caution is over-spraying. This is a fast-acting formula, and a few owners note that doubling up on the same spot can burn the grass, and that walking on freshly treated turf may brown it. Treated correctly, though, it is one of the quickest cool-season tools here — just respect the label rate and keep off the lawn until it dries.
Built for cold snaps: it performs in cool weather where other sprays lag, hitting 90+ weeds with visible effects within hours and rainfast in three.
Respect the rate: over-spraying the same weeds or walking on wet turf can burn the grass, so follow the mix carefully.
Go for this when: you need fast results in cooler weather and want the freedom to reseed in about a week.
Hold off if: you tend to eyeball your mixing or want to spray without watching the walk-on timing.
9. Southern Ag Lawn Weed Killer with Trimec Herbicide, 128oz – 1 Gallon 13504
A gallon jug of three proven weed killers, sized for centipede and Southern turf.
For Southern lawns, this gallon is the workhorse. It carries a patented blend of three proven weed killers in 128 fluid ounces, is directed for use on 9 turf types, and can be applied through conventional or hose-end sprayers. The active trio reaches clover, thistle, dandelion, wild strawberries, burweed, and creeping charlie, and it is a particular favorite on centipede and Bermuda lawns where many broadleaf sprays are too harsh.
The gallon is genuinely generous. Owners treating a couple of acres describe one spray wiping out weeds that were outgrowing the grass, with no harm to the turf, and others eliminated the vast majority of weeds in a single pass with no regrowth after a couple of months. On burweed that had beaten the big-box options, this one did the job. Concentrated as it is, a gallon goes a long way for most home lawns.
The one honest quirk is that a few users find it finicky if they spray from the same tank they used before — a test patch worked great, but a later pass killed grass instead of weeds. That points to careful sprayer cleaning between uses rather than a formula flaw, but it is worth respecting. Apply it per the label, and it rewards you with a big, clear lawn.
What the gallon delivers
- Patented three-way blend for 9 turf types, built for Southern grasses
- Handles clover, thistle, dandelion, burweed, and creeping charlie
- One 128-fluid-ounce gallon goes a long way on a home lawn
Watch-outs
- Results can take about a week on some weeds, so plan ahead
- Sprayer residue from previous use can cause inconsistent results
A great match for: Southern lawns on centipede or Bermuda where you want a big value jug of three-way broadleaf killer.
Not the one if: you only have a small yard or prefer a ready-to-use bottle with no mixing at all.
Understanding the Specs
Coverage in square feet
Coverage tells you how large an area one bottle treats, so you can match the product to your lawn before you buy. A bottle rated for 43,560 square feet handles a full acre, while one rated for 5,000 square feet is built for a small yard or a few weedy patches. Always compare the coverage figure to the actual size of your lawn and treat the number as the real limit on the job.
Concentrate versus ready-to-use
A concentrate means you mix the product with water at a set rate, which lets you spray only what you need and stretch a single bottle further. A ready-to-use version or a hose-end bottle skips the mixing, trading that control for speed. If your lawn is large, concentrate usually wins; if it is small or you have never sprayed before, the ready-to-spray style keeps it simple.
Timing and rainfastness
Broadleaf formulas work best when weeds are young and actively growing in spring or fall. Rainfastness is how long the spray needs to dry before rain will not wash it away — some products resist a shower in about three hours, others around six. Spray when no rain is due in that window, and keep the mist off flowers and shrubs, which are broadleaf plants too.
Active ingredients and the three-way blend
Many good dandelion killers combine more than one active ingredient, such as 2,4-D, MCPA, and Dicamba, so the formula attacks weeds in more than one way. A three-way blend tends to cover a wider weed list than a single-active product. A single active still works well on dandelions specifically, so match the blend to how many different weeds you are fighting.
