Our Review Criteria: Whether a herbicide is selective or non-selective decides the buy before anything else, because a non-selective formula kills the turf it lands on along with the weed, and no amount of coverage or price makes up for a dead lawn. From there, each product here is judged against its EPA-registered label: the active ingredients it carries, the weed classes those ingredients actually control (broadleaf, grassy, or nutsedge), and the grass types the label clears, since a blend that is safe on fescue can injure St. Augustine, bentgrass, or buffalograss. Timing carries the same weight as chemistry. A pre-emergent only works in the window before crabgrass germinates, so we check that a product’s label and university extension guidance from programs including Missouri, Michigan State, Penn State, Maryland, and Kansas State agree on when it goes down. We read the same label for the practical numbers a homeowner has to live with: coverage area, application method (granular spreader, hose-end, or tank sprayer), how long the product needs before rain, and the re-entry interval that keeps children and pets off the treated grass. Each pick is matched to one clear job rather than sold as a cure-all, and the trade-offs are stated plainly so the call stays yours. Every recommendation is re-checked for availability, and anything discontinued or out of stock is replaced.

Most weed killers fail for one of two reasons: the bottle was never built for the weed you have, or it went down at the wrong time of year. Match those two things and the lawn does the rest.

The 10 best lawn weed killers below are sorted by the job they actually do. A pre-emergent stops crabgrass before it sprouts. A selective spray takes out dandelions and clover while your grass keeps growing. A sedge-specific formula handles nutsedge, which shrugs off almost everything else.

Every pick is read off its label and its active ingredients, then checked against university extension guidance on when and how to apply it. Here is what to buy, and when to spray it.


How to Choose the Best Weed Killer for Lawns

Not sure where to start with a weed killer? Here is a handy guide that breaks down the most important criteria so you can choose a formula that is just right for you.

Type

First, decide whether you need a pre-emergent or a post-emergent. A pre-emergent goes down before the weed sprouts and stops the seed from establishing, so timing is everything: aim for the window when the mean soil temperature at a 1 inch depth has held at 50 to 55 degrees Fahrenheit for about five days, which is just ahead of the roughly 60 degrees where crabgrass germinates (1). Miss that window and the product cannot do its job, no matter how good it is.

A post-emergent is for weeds you can already see. It has to land on live foliage, so it works on what is growing now and does nothing for next spring’s seed bank. Plenty of lawns need one of each across a season, not one bottle doing both.

Weed Type

Match the product to the weeds you actually have. There are many types of weeds, and they fall into three groups that respond to three different chemistries. Broadleaf weeds (dandelion, clover, chickweed, plantain) fall to selective broadleaf blends. Grassy weeds (crabgrass, foxtail, goosegrass) need a pre-emergent, or a grassy-weed post-emergent once they are up.

Sedges are the third group, and they trip people up. Nutsedge looks like a fast, glossy grass but it is a sedge, so a standard broadleaf spray barely touches it. It needs a sedge-specific product, and it is most vulnerable in early summer while it is young and has not yet loaded its underground tubers.

Read the label’s weed list before you buy. A product that does not name your weed will not kill it.

Lawn Size

When shopping, check the packaging to see how many square feet the weed killer covers. Make sure you have enough for your entire lawn. This ranges from about 100 square feet for spot treatments all the way up to 25,000 square feet for concentrates.

Top Tip

Buy larger sizes if you plan to use the product repeatedly. It is a good idea to have some on standby in case the weeds make a comeback.

Selectivity

You will find both selective and non-selective weed killers on the market.

Selective formulas kill weeds without harming the grass. If you have dandelions, daisies, and other weeds growing in your turf, choose a selective weed killer so your lawn stays green.

Non-selective weed killers kill everything they touch, including grass. If you are trying to protect your lawn, do not choose one of these. However, if you have weeds on a sidewalk, driveway, or patio, a non-selective weed killer works perfectly.

Performance

Speed and a finished kill are two different things, and the label’s “visible results” time only tells you the first one. A contact spray can brown a weed in three hours and still leave a live root behind. A systemic formula can look like it is doing nothing for a week, then take the whole plant.

Decide which one your problem needs. For a patio crack or a driveway joint, fast browning is enough. For a perennial like dandelion, clover, or bindweed, ignore the speed claim and pick a systemic product that moves down into the roots.

Persistence

Check how long the effects of the product last. Some formulas prevent growth for up to a year, while others require frequent re-application.

You should also consider rainfastness. Some products are rainproof within a couple of hours, while others take a full day. You need to plan your application around the weather forecast.

Toxicity

The number that matters is the label’s re-entry interval. For most lawn sprays it is “until the treated area has dried”, which in practice means a few hours on a warm day and longer in cool or damp weather. Keep children and pets off the lawn until then, and off granular products until you have watered them in and the lawn has dried.

Read the ingredient panel before you buy. Concentrated vinegar is not automatically gentle, since it is corrosive and needs gloves and eye protection, and a selective lawn herbicide is only “lawn safe” for the grass types its label lists.


Product Reviews

Here are the 10 lawn weed killers worth your money, each matched to a specific job rather than sold as a cure-all. Every entry was assessed on its active ingredients, what the label actually lists as controlled, how selective it is around turf, coverage, and how easy it is to apply without hurting the grass.

Read the award on each one before the score. The best pick for a lawn full of dandelions is not the best pick for nutsedge, and neither is what you want for crabgrass prevention.

This is the pick when selectivity matters most. The active ingredient is the dimethylamine salt of 2,4-D, the classic selective broadleaf herbicide, so it will get rid of weeds like dandelion, thistle, plantain, and ground ivy while established turf grass keeps standing.

Check your weed against that class first. Broadleaf and noxious plants are what 2,4-D is built for, so grassy invaders shrug it off and a lawn overrun with crabgrass or nutsedge is the wrong job for this bottle.

It also reaches the woody and noxious end of the list, including nettles, alder, elderberry, honeysuckle, and wild onion. Check the packaging for the full list before you buy.

It is a concentrate, not a ready-to-use spray, so you need a tank sprayer and you mix it at the label rate. That is also why one jug goes a long way across a big property.

The label covers turfgrass, pastures, parks, drainage ditch banks, and around ponds. Who it is for: someone with a large lawn or acreage, a broadleaf problem, and a sprayer already in the shed. It is overkill for a few dandelions by the mailbox.

Take Note

You may have to apply the solution a few times for certain weeds, such as blue lettuce, bur ragweed, and Canadian thistle.

Pros

  • Selective weed killer that protects grass.
  • Suitable for various weeds, specifically broadleaf and noxious ones.
  • You can use it across many different sites.
  • Pairs best with Hi-Yield Spreader Sticker.
  • Highly concentrated formula.

Cons

  • Does not ship to California.
  • The label warns it can injure St. Augustine, carpetgrass, bentgrass, buffalograss, and dichondra lawns.
  • May not be as effective as other products on non-broadleaf weeds.

Dandelions and clover are the two weeds most likely to spoil an otherwise green lawn, and this Ortho WeedClear spray goes after them without wrecking your turf. It is a selective formula, so it kills the listed weeds down to the root and leaves common lawn grasses unharmed when you follow the label.

Ortho lists three herbicides in the blend, 2,4-D, mecoprop-p, and dicamba, and rates the formula for over 250 listed weeds killed down to the root, the same three actives the label lists. That mix is why it clears the dandelions out in the open and the clover creeping through thicker patches.

It arrives ready to use with a Comfort Wand, so there is no pumping and nothing to dilute. You point the wand, press the trigger, and spot-treat what you can see.

It becomes rainproof one hour after the spray dries, and the label clears people and pets to walk on the area once it has dried fully. Treated weeds usually curl and brown within hours.

Pros

  • Selective formula that spares listed lawn grasses.
  • Kills dandelions and clover down to the root.
  • No mixing and no pumping thanks to the Comfort Wand.
  • Rainproof one hour after the spray dries.
  • People and pets can return once the treated area is dry.

Cons

  • Only lawn-safe on the grass types named on the label.
  • A full gallon is bulky for quick spot jobs.
  • Mature, established weeds may need a second treatment.

Spectracide advertises the ability to kill the highest amount of weed types. It targets over 470 species, more than any herbicide on this list. If you have weeds in your lawn, there is a good chance this product will handle them.

This includes broadleaf and grassy weeds such as yellow nutsedge, crabgrass, and chickweed. The product label discloses the complete list if you are curious.

It is also quick. The formula moves from the leaf down into the root rather than just scorching the surface, and you can see wilting in as little as five hours on a warm, actively growing weed.

It is selective, so it clears the listed weeds and leaves common lawn grasses alone when you follow the label. Confirm your grass type is on that label first, since a selective product is only lawn-safe on the turf species it names.

Pros

  • Kills over 470 different types of weeds.
  • Does not kill grass (only weeds listed).
  • Kills weeds at the root, not just on the surface.
  • Results evident within five hours.
  • Handles broadleaf and grassy weeds from one bottle.
  • Ready-to-use formula.

Cons

  • It may struggle to kill mature dandelions entirely in one go.
  • Stubborn weeds need a repeat application.
  • Not effective below 45 or above 90 degrees Fahrenheit.
  • Only lawn-safe on the grass types printed on the label.

Tackle those weeds before they even make an appearance. Quali-Pro Prodiamine is one of the best pre-emergent weed killers on the market for keeping your lawn pristine.

This formula prevents weeds from sprouting. You can use it on nurseries, lawns, turf, and golf courses. It effectively blocks henbit, knotweed, spurge, foxtail, annual bluegrass, chickweed, and goosegrass.

It is suitable for use in spring or fall. Each application provides enough control to last through the season.

The active ingredient is prodiamine, one of the four actives (with dithiopyr, pendimethalin, and mesotrione) that extension programs name for crabgrass prevention. It forms a chemical barrier in the top layer of soil that stops germinating seeds from establishing, which is why two well-timed applications a year cover most lawns.

Two things decide whether it works. Put it down before soil temperatures climb into the 60s, and water it in with rain or irrigation so it moves into the soil before the weeds emerge. A pre-emergent left dry on the surface is a wasted application.

Try This

The label doses this one by weight, not by spoonfuls. It calls for 0.185 to 0.83 ounces of the granules per 1,000 square feet, depending on your grass type and how long you want the barrier to hold, mixed into at least half a gallon of water per 1,000 square feet.

Pros

  • Suitable for spring and autumn use.
  • Prevents weeds from germinating all season long.
  • Works great with fertilizers and iron solutions.
  • Suitable for various sites, including lawns and golf courses.
  • A 5 pound jug covers roughly 96,000 square feet at the heaviest label rate, and much more at the lighter ones.

Cons

  • Confusing and vague instructions for a home user.
  • Does not kill existing weeds, it only prevents new ones.
  • Useless if the timing slips past the germination window.
  • Has to be watered in to work at all.

A weed and feed does two jobs in one pass, and this liquid Scotts formula is the pick if you want to green up the lawn while you clear the weeds. It pairs a fast-release nitrogen feed with a broadleaf weed killer, so a single application both fertilizes the grass and treats the weeds growing in it.

The herbicide side uses 2,4-D and mecoprop-p to target listed broadleaf weeds, including dandelion, clover, and poison ivy. It will not touch grassy weeds like crabgrass, so treat it as a broadleaf tool rather than an everything killer.

It connects straight to a garden hose, which means no measuring and no separate spreader. Scotts rates one 32 ounce bottle at 6,000 square feet of warm-season lawn or 4,000 square feet of cool-season lawn.

For the feed and the weed control to work together, the weeds need to be young and actively growing when you spray. Time it for the growing season rather than a dormant lawn.

Pros

  • Feeds the lawn and kills weeds in one pass.
  • Fast-release nitrogen greens up the grass.
  • Targets dandelion, clover, and other listed broadleaf weeds.
  • Hose-end sprayer with no mixing or spreader.
  • Covers up to 6,000 square feet on warm-season turf.

Cons

  • Broadleaf only, so it ignores crabgrass and grassy weeds.
  • Coverage drops to about 4,000 square feet on cool-season lawns.
  • Works only when the weeds are actively growing.
  • Carries a California Proposition 65 warning.

Type Post-emergence (weed and feed)

If you want weeds gone without synthetic herbicides, this is the honest version of the natural option. Vinegar and water are the only ingredients, but at 30 percent acetic acid it is six times the strength of the 5 percent bottle in your pantry.

Know exactly what acetic acid does before you buy it. It is a non-selective contact herbicide: it has to physically wet the foliage, it breaks open the leaf cells it touches, and the top growth browns fast, often within a day or two. It does not travel inside the plant. Annual weeds and young seedlings do die; established perennials like dandelion regrow from the root and need repeat hits.

It is also non-selective, so it burns lawn grass exactly as readily as it burns the weed. Use it in driveway cracks, along fences, and on patio joints, and spot-treat rather than spray across turf.

Treat the concentrate as a chemical, not a salad dressing. Acetic acid at this strength can permanently damage the cornea and burn skin, so gloves and eye protection are not optional (2). The same acid also cleans hard-water scale, oven doors, and drains, which is a genuine second use for the bottle.

Pros

  • Biodegradable, with no synthetic herbicide residue.
  • Two ingredients only: acetic acid and water.
  • Visible burn-down on young weeds within a day or two.
  • Six times stronger than household vinegar, so it can be diluted down for lighter jobs.
  • Doubles as a hard-water and scale cleaner.

Cons

  • Contact only: it top-kills, and perennials regrow from the root.
  • Non-selective, so it scorches lawn grass it lands on.
  • Corrosive at full strength; gloves and eye protection are required.
  • No sprayer and no application instructions in the box.

Nutsedge shrugs off ordinary lawn sprays, so it earns a dedicated product. This Ortho formula is built around sulfentrazone, an active ingredient that targets nutsedge and nutgrass specifically, and it clears kyllinga and more than 50 other listed weeds along the way.

It is selective, so it works on established northern and southern turf grasses without taking out the lawn. Alongside the sedges, it also handles broadleaf weeds such as wild violet, dollarweed, dandelion, purslane, and spurge.

The bottle attaches to a garden hose and covers up to 5,000 square feet, so you can broadcast it across a whole lawn rather than spot-spraying clump by clump.

Timing decides how well it works. Nutsedge is most susceptible in early summer while the plants are young and have not yet built up their underground tubers; once those tubers are loaded, the patch keeps coming back and you are into repeat treatments. Treated sedge yellows and browns over the following days, but tubers already in the soil can resprout, so a second treatment is common. Check the rainproof window printed on the label and plan the spray around the forecast.

Keep children and pets off the treated lawn until the spray has dried fully.

Pros

  • Built to kill nutsedge and nutgrass, which most sprays miss.
  • Selective and safe for listed northern and southern turf grasses.
  • Also clears kyllinga and 50 or more other listed weeds.
  • Hose-end applicator covers up to 5,000 square feet.

Cons

  • A specialist tool, not a broad all-weed killer.
  • Stubborn nutsedge usually needs more than one treatment.
  • Keep kids and pets off the lawn until it has dried.

This is the bottle for the person who wants to walk outside, hit the weeds in the driveway cracks, and be done. It ships ready to use with a trigger nozzle, so there is nothing to mix and nothing to pour into a tank.

Know what is in it before you point it at anything green. Spectracide builds this line on diquat dibromide, fluazifop-p-butyl, and dicamba rather than glyphosate.

That blend is non-selective: it kills lawn grass as readily as it kills the weed. Use it in flower beds, on walkways, along fence lines, and in driveway seams, and spray on a warm, sunny day while the weeds are actively growing.

It is rainproof after 15 minutes, wilting shows up in as little as three hours, and the weed is usually dead inside a day. Who it is for: a homeowner with scattered weeds in hard surfaces and beds who wants zero setup. If you need to clear weeds out of turf without killing the turf, buy a selective spray instead.

Keep In Mind

The fast brown-down is top-kill, not proof the root is dead. Stubborn perennials like dandelion often push back up, so plan on a second hit rather than assuming one spray finished the job.

Pros

  • You can plant new growth after one day of application.
  • Rainproof within 15 minutes.
  • Notice results in as little as three hours.
  • Handy spray bottle for easy application.
  • Burns down listed weeds and grasses on contact, including clover and dandelion.
  • Suitable for flower beds, driveways, and around fences.

Cons

  • Non-selective: it kills any grass it lands on, so it is not a lawn spray.
  • May take a few applications to kill stubborn weeds.
  • Sprayer lacks a stream function.

If you left it too late and the weeds are already springing up, you need a post-emergence weed killer. Reach for the Compare-N-Save Concentrate.

It uses glyphosate, which is systemic: the plant takes it in through the leaves and moves it down into the roots, so the whole weed dies rather than just the visible top.

That strength is also the catch. Glyphosate is non-selective and kills whatever green tissue it lands on, grass included, so this is a tool for driveway cracks, fence lines, and beds, not for spraying across turf. Shield anything you want to keep and spray on a still day.

You can expect visible results in two to four days, though a stubborn perennial can take up to three weeks to fully die back.

You can use this for killing weeds, grass, stumps, brush, and vines. It is suitable for driveways, along fences, and walkways.

This bottle makes up to 85 gallons of spray solution when diluted. That covers up to 25,000 square feet. You are definitely getting a lot for your money with this budget-friendly option.

Pros

  • Rainproof in as little as two hours.
  • Kills over 175 different types of weeds.
  • Takes only one application to see results.
  • Can be used in a variety of locations.
  • Coverage up to 25,000 square feet.
  • Makes up to 85 gallons per bottle.

Cons

  • It can take up to three weeks to see full death of the plant.
  • Non-selective: It will kill your grass if you aren’t careful.

If you have a vast lawn, it is smart to shop accordingly so you don’t run out of product halfway through. This Weed and Feed covers up to 16,000 square feet, making it perfect for larger properties.

It is a four-way herbicide, meaning it combines four active ingredients instead of one. That is not marketing: extension guidance is that the most effective broadleaf products blend several actives rather than relying on one, because no single compound controls every broadleaf weed. A multi-active blend casts a wider net across the mixed weed populations a big lawn usually carries.

It clears more than 250 listed weed types, including dandelion, plantain, and clover, while the slow-release nitrogen feeds the turf so the grass thickens and crowds the gaps.

The granular format is the trade-off. You need a spreader, and the product has to be watered in, so plan it around irrigation or a forecast shower rather than a dry week.

Pros

  • Suitable for application during spring and fall.
  • Contains quick and slow-releasing nitrogen to feed grass simultaneously.
  • Great coverage at 16,000 square feet.
  • Good choice for professional and personal use.
  • Four-way herbicide for quicker results.
  • Kills over 250 weed types.

Cons

  • It is not pet-friendly.
  • If you don’t have an irrigation system, application is tricky (needs watering in).
  • It might be a few weeks before you see results.

FAQs About Using Weed Killers

When Should I Apply Weed Killer to My Lawn?

Apply weed killer while the weeds are actively growing, on a warm day with no rain in the 24 hour forecast. The window depends on the type: a pre-emergent goes down in spring once soil at 1 inch has held around 50 to 55 degrees Fahrenheit for roughly five days, before crabgrass germinates. For perennial broadleaf weeds like dandelion and clover, early September to early November is the strongest window, because the plants are pulling food reserves down into their roots and carry the herbicide along with them.

What Happens if It Rains After You Spray Weeds?

Rain before the product turns rainproof washes the herbicide off the leaf before the plant can absorb it, so the treatment underperforms or fails outright. Spray on a sunny day with no rain forecast for 24 hours, and give the spray time to dry on the leaf surface (3). Check the rainproof window printed on your label, since it ranges from about 15 minutes to several hours by formula.

Granular pre-emergents are the exception: those actually need rain or irrigation to move them into the soil.

Does Vinegar, Epsom Salt, and Dawn Dish Soap Kill Weeds?

No, not reliably. The mix works by contact: the acetic acid in the vinegar burns the leaf tissue it touches, the salt draws out moisture, and the dish soap helps the liquid cling. The top growth browns, which looks like success.

Nothing in it travels inside the plant, though, so the root survives and a perennial weed like dandelion simply resprouts. It also has no selectivity, so it scorches lawn grass just as fast as the weed.

Does Baking Soda Kill Weeds?

To a point, yes. Baking soda draws moisture out of leaf cells and dries the foliage, so it can finish off young weeds in pavement cracks. It works on contact only, though, so the root of an established weed survives and regrows, and repeat doses load the soil with sodium. Use it as a spot fix on hard surfaces, not as a lawn treatment.

Does Vinegar Kill Weeds Permanently?

Usually not. Acetic acid is a non-selective contact herbicide: it has to touch the foliage, it destroys the leaf cells it lands on, and it does not move through the plant, so perennial weeds regrow from roots the spray never reached.

Young annual seedlings can be killed outright. A mature dandelion or thistle with a deep taproot will be back, so plan on repeat applications rather than a one-shot fix.

How Often Can I Apply Weed Killer to My Lawn?

Twice a year covers most lawns: a pre-emergent in spring and a broadleaf treatment in fall. That split matches how the weeds behave, since spring stops the crabgrass seed and fall catches the perennials as they move reserves into their roots.

Going beyond the label rate or frequency risks scorching the turf without killing anything extra. Check your product’s directions, because a spot-treatment spray and a whole-lawn granular follow different schedules.

Does Mowing the Lawn Spread Weeds?

Not if you bag the clippings when weeds have gone to seed, since collecting them stops the seed from scattering across the lawn. Mowing done right does the opposite of spreading weeds.

Height is the lever most people miss. Cutting above 3 inches greatly reduces weed pressure: taller, denser turf shades the soil, which keeps weed seed from germinating in the first place. Scalping a lawn short is one of the surest ways to invite weeds in.

Is Weed Killer Safe for Pets?

Only after the treated area has dried completely. Keep pets indoors while you apply the product and wait until the liquid is fully dry, which usually takes 2 to 24 hours depending on the brand, before you let them back onto the lawn.

What Temperature Is Best for Weed Killer?

Aim for a range of 65 to 85 degrees Fahrenheit. Colder than that and the weeds take up too little of the herbicide; hotter than that and the spray evaporates before it can work and can heat-stress your lawn grass.

Tips for Using Weed Killers for Lawns

Wondering how to make the most of your weed killer? Besides reading the instructions for your specific product, here are some other handy tips that can make the product more effective:

  • Dilute accordingly: Stick to the product advice. Stronger concentrations aren’t always better and can damage your lawn. If it doesn’t work the first time, reapply with the same concentration rather than increasing it.
  • Follow mixing instructions: If you need to mix the product with water or a surfactant, follow instructions properly and mix them in the order instructed.
  • Keep clean: Clean your tools thoroughly before and after use to avoid cross-contamination.
  • Check weather and water: Don’t use weed killers on windy days. The wind can drift the spray onto plants you love or into waterways.
  • Protect yourself: Always use protective equipment such as gloves, masks, and clothing that covers your arms and legs.
  • Keep away kids and pets: Keep children and pets away from the area until the product is fully dry and safe.
  • Don’t bring weed killers inside: Reserve measuring cups and sprayers for outside use only. Do not bring them back into the kitchen.
  • Dispose properly: Don’t pour excess mixture down the sink or into a trash can. Store what is left for the next application, and follow the label’s disposal instructions.
  • Mow high: Keep the mower above 3 inches. Taller, denser turf shades the soil and blocks weed seed from germinating, which cuts your weed pressure before a single spray.
  • Don’t mow around a spray: Leave the mower parked for two days before and two days after a broadleaf treatment, so there is leaf surface to absorb the herbicide.
  • Choose a warm day: Aim to kill weeds on a warm day (above 60 degrees). This ensures the plant is active and absorbs the herbicide.
  • Avoid water after application: Lightly dampen the weeds before applying granular weed killers, but keep liquid sprays dry. Aim to keep the area dry for 24 to 48 hours after application.
