Clover creeping into your lawn is annoying — you want it gone, but you definitely don’t want to nuke your grass in the process. A good selective clover killer targets the clover (and other broadleaf weeds) while leaving your lawn healthy and green, and the trick is picking the one that matches your yard size, grass type, and patience for reapplying.
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.
Whether you are spot-treating a small patch or spraying a whole acre, here is a no-nonsense breakdown of the lawn clover killer options that actually work without wrecking your turf.

How To Choose The Best Lawn Clover Killer
You need a clover killer that matches your lawn size, your grass type, and if you want a ready-to-use spray or a concentrate you mix yourself. A selective herbicide (a weed killer that targets only certain plants) with active ingredients like 2,4-D, dicamba, or triclopyr will kill clover and other broadleaf weeds without damaging your grass — as long as you follow the label directions.
Selective vs Non-Selective Herbicides
A selective herbicide kills only broadleaf weeds (like clover, dandelion, and chickweed) while leaving your grass untouched. Non-selective herbicides kill everything they touch — you do not want that on your lawn. Every product here is a selective herbicide, so you can spray clover without killing your turf.
Concentrate vs Ready-to-Use (RTU)
Concentrates (like the Spectracide and Fertilome options) require you to mix the liquid with water in a sprayer, giving you more coverage per ounce and usually a better price per square foot. RTU sprays (like the Ortho Weed B Gon trigger bottle) come pre-mixed and are perfect for small patches and quick spot treatments — but they cost more per ounce and cover less area.
Grass Type Compatibility
Not every clover killer works on every grass type. Some are safe for St. Augustinegrass, Bermudagrass, and Zoysiagrass, while others can damage Floratam St. Augustine or Centipedegrass. Always check the label for your specific grass variety before spraying, or you could end up with brown patches where the clad used to be.

In‑Depth Reviews
1. Spectracide Large Plot Weed Stop for Lawns Concentrate, 1 Gallon
The gallon concentrate that covers a massive yard while staying affordable.
For large lawns, this is the clover killer to beat — it covers up to 32,000 square feet of northern grasses or 42,500 square feet of southern grasses from a single 128-fluid-ounce bottle. That is 6.4 times the coverage of the Ortho WeedClear refill (which covers 5,000 square feet), making it the clear winner if you have serious acreage.
It uses a selective formula that kills more than 200 types of broadleaf weeds (including clover, dandelion, and chickweed) without harming your lawn when used as directed. One reviewer noted it took a third application for tough weeds like bull head and foxtail, but noted it works well on dollar weed, chickweed, and nutsedge — especially at a higher concentration. Another customer praised its fast wilting effect and easy mix, calling it excellent value for a 1-gallon concentrate.
The catch is that some users find it slow-acting compared to other options, and it may require a second or third spray for stubborn clover patches.
Why It Wins
- 32,000 sq ft coverage from one gallon — huge value
- Kills 200+ weeds including clover, dandelion, chickweed
- Rainproof in 6 hours
The Trade-Offs
- Slow-acting for some; may need multiple applications
- Not effective on bull head and foxtail at standard rates
For the big-yard owner: Best for someone with a large lawn who wants to cover the most ground per dollar.
Heads up: You may need a second or third spray for really persistent clover patches.
2. Bonide Chickweed, Clover & Oxalis Killer, 128 oz Ready-to-Use Spray
The targeted pre-mixed spray that hits clover and chickweed without the mixing hassle.
If you want a ready-to-use (RTU) spray that is purpose-built for clover, chickweed, and oxalis, this 128-fluid-ounce Bonide bottle is the top contender. Its active ingredients — dicamba and triclopyr — are a strong combination for broadleaf weeds, and buyers report it kills dandelions in one spray with clovers browning in about 3 days. One buyer mentioned it is “clear, nearly odorless” and that the concentrate version covers 5,000 sq ft at about per 1,000 sq ft — half the cost of Ortho Weed B Gone.
However, it has mixed results on clover: while many users see great results, one owner reported it only slightly turned top leaves light brown without fully killing the patches. The included hand sprayer is adequate for small areas, but multiple reviewers recommend switching to a pump sprayer for larger lawns.
Bottom line — this is a fast-acting, odorless RTU that works great on chickweed and dandelions, but you may need a second pass on thick clover.
What Works
- Kills dandelions and chickweed in one spray
- Nearly odorless and clear
- Dicamba + triclopyr mix is potent on broadleaf weeds
What to Watch
- Mixed results on clover — some users saw incomplete kill
- Hand sprayer is poor for large lawns
For the no-mix user: Ideal if you want a pre-mixed spray that targets clover without having to measure and mix concentrate.
Keep in mind: Thick clover patches may need a second application, so plan accordingly.
3. Fertilome Weed Free Zone (16 oz)
The small-batch concentrate that packs a punch on Bermuda grass and sticker burrs.
At just 16 fluid ounces, this Fertilome concentrate controls over 80 broadleaf weeds including clover, spurge, chickweed, and thistle, and is safe on Kentucky Bluegrass, Bermudagrass, Zoysiagrass, and more. Unlike the Spectracide (which covers 32,000 sq ft), the Fertilome’s coverage depends on how much you mix per gallon — one reviewer used 2 oz per gallon and covered 0.2 acres with 10 oz, getting visible results in 2 days. That is faster than the Spectracide’s slower action, according to buyers.
Owners mention that it is effective on Bermuda grass — one customer saw visible results in 2 days using 3 oz per gallon with dish soap as a surfactant. Another described a “night-and-day” difference vs untreated areas. However, one customer observed it does not work on dandelions, and it cannot be used while seeding because it kills seedlings. Another pointed out it is comparable to the brand Tenacity but is less concentrated and won’t bleach your grass.
The downside: at 16 ounces, you get less liquid per bottle than the Spectracide (128 ounces), but the concentrate goes a long way if you mix it right.
What Shines
- Fast results — weeds visible in 2 days
- Safe on Bermuda, Zoysia, and Kentucky Bluegrass
- Controls 80+ weeds including clover, spurge, chickweed
What Holds It Back
- Does not work on dandelions for some users
- Cannot be used while seeding (kills seedlings)
For the precision sprayer: Ideal if you have a medium lawn and want a potent concentrate you can measure yourself.
Just know: It won’t kill dandelions, so you’ll need a separate product for those.
4. Ortho WeedClear Weed Killer for Lawns Refill, 1 Gal.
The refill that offers fast visible results for spot killers on clover and dandelion.
If you already own the Ortho Comfort Wand applicator, this 1-gallon refill is the most convenient way to spot-treat clover across your lawn. It covers 5,000 square feet and kills over 250 listed weeds including dandelion, chickweed, and clover down to the root — without harming your grass when used as directed. One user highlighted visible effects within an hour and weeds brown/dead by day one, while other users praised its effectiveness on nutsedge and windblown weeds.
Compared to the Spectracide concentrate (32,000 sq ft coverage), the WeedClear covers a fraction of the area — 5,000 sq ft vs 32,000 sq ft — so it is better suited for smaller lawns or focused spot treatments. It is safe on St. Augustinegrass (not Floratam), Bermudagrass, Centipedegrass, Zoysiagrass, and several other common turf types. Multiple reviewers noted it “really works” on flower weeds without killing the grass, but one shopper added “not all that,” so expectations should be realistic.
The refill format is a money-saver compared to buying a new RTU bottle, but you pay for convenience in coverage.
Why It’s Handy
- Works fast — visible effects within an hour
- Refill for Comfort Wand saves money on packaging
- Safe on several common grass types
The Catch
- Only 5,000 sq ft coverage — not for large lawns
- Mixed reviews on overall effectiveness
For the Comfort Wand owner: Best if you already have the Ortho applicator and want a cheap refill for quick spot treatments.
Limit: Not enough coverage for a large yard — go with the Spectracide instead.
5. Ortho Weed B Gon Weed Killer, 24oz RTU Trigger
The trigger-ready spray that tackles clover in small patches with satisfying speed.
For small clover patches or a quick weekend spray, the Ortho Weed B Gon 24oz RTU kills dandelions, clover, and 250+ other broadleaf weeds down to the root without harming the lawn when used as directed. One buyer described “seeing great results killing clover and other weeds without killing the grass.” Another reviewer called it “very effective for killing weeds in your lawn, without harming the grass.”
That means you cannot adjust the concentration or cover large areas efficiently. One reviewer noted you should “wear gloves and masks” when using it due to the chemicals. The trigger sprayer is convenient for one-handed use on walkways and small flower beds.
If your clover problem is small and contained, this is the simplest option — grab, spray, done.
Simple Wins
- Kills clover and dandelion without harming grass
- Trigger sprayer for easy one-handed use
- Results in hours — buyers saw visible die-off quickly
Small Thinking
- Only 24 oz — covers a small area
- No mixing means you can’t adjust concentration
For the patch fixer: Best for small lawns or spot spraying individual clover clumps without the mixing fuss.
Heads up: For large areas, you will run out fast and pay more per ounce than a concentrate.
Understanding the Specs
Liquid Volume vs Coverage
Liquid volume (measured in fluid ounces) tells you how much product is in the bottle, but coverage (measured in square feet) tells you how much area it will treat. A concentrate like the Spectracide gives you 128 fluid ounces covering 32,000 square feet — far more than an RTU spray like the Ortho Weed B Gon (24 oz covering a much smaller area). When comparing, look at the coverage number per gallon, not just the bottle size.
Ready-to-Use (RTU) vs Concentrate
RTU sprays come pre-mixed and are ready to spray straight from the bottle — great for small patches and quick jobs. Concentrates require you to mix the liquid with water in a sprayer, which takes a few extra minutes but gives you much more coverage per ounce and usually a lower cost per square foot. If you don’t own a garden sprayer, grab an RTU; if you have a large lawn, get a concentrate.
