Clover in Your Lawn: Whether to Keep It, and How to Remove It
Clover does a lawn no agronomic harm — it fixes nitrogen and stays green in drought — and a clover-heavy lawn is usually an underfed one; keeping it is a preference. To remove it, feed the grass and treat in fall with a systemic broadleaf herbicide labeled for your grass, mowing off flowers first, expecting a second pass weeks later.
Clover was a standard component of lawn seed mixes until the 1950s, when selective broadleaf herbicides arrived that killed it along with the actual weeds, and the industry reclassified it as one rather than admit the collateral damage. That history matters because it means "is clover a weed" has no agronomic answer — it is a preference, and a growing number of people are deliberately seeding it back in. What clover is not is arbitrary: it fixes its own nitrogen, stays green through drought that browns the grass around it, and appears in lawns that are low in nitrogen. So before deciding how to get rid of it, it is worth knowing that a clover-heavy lawn is usually an underfed one.
Keep it or remove it: decide, then act
- Step 1
Decide what you actually want before you buy anything
The case for keeping it: clover fixes nitrogen from the air and feeds the grass around it, needing roughly a third less fertilizer overall; it stays green in summer drought when cool-season grass goes dormant; it tolerates poor soil; and it flowers for pollinators. The case against: the flowers attract bees where children play barefoot, it is slippery underfoot when wet, it stains clothing more readily than grass, and it grows in patches rather than evenly unless you seed it deliberately. Neither answer is wrong. Everything below depends on which you pick.
- Step 2
Either way, read what a clover takeover is telling you
Clover manufactures its own nitrogen through bacteria in its root nodules, so it has a decisive advantage in soil where nitrogen is short — grass slows down and clover does not. A lawn going noticeably clover-heavy is very often an underfed lawn, and sometimes a compacted or low-pH one where the grass cannot take up what is there. A soil test checks the pH side of that for about twenty dollars, along with phosphorus and potassium on the lab's own scale; compaction is a probe check rather than a lab number, and a routine test may not report nitrogen at all, so weigh the result with how the lawn has been fed. Together they change what you should do next under either decision.
- Step 3
To reduce it without herbicide: feed the grass properly
Nitrogen decides the competition between clover and grass, so restoring a normal feeding program shifts it back toward the grass on its own — slowly, over a season or two, but without any chemistry. Combine it with mowing toward the top of your grass's range, since clover is low-growing and a taller canopy shades it. This is the approach for someone who wants less clover rather than none.
Do not compensate with a heavier feeding. Plan about 1 lb of nitrogen per 1,000 sq ft per feeding or less — a conservative default, not a universal limit. Excess nitrogen can invite disease and leach below the roots — split the annual budget across the season instead.
Local fertilizer rules can be stricter than this and can override it: several states and counties set a lower per-application limit, cap the soluble (quick-release) fraction separately, require a share of slow-release nitrogen, or ban applications outright during a seasonal blackout. Check your state or county rules before you spread. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
- Step 4
To remove it: treat in fall, and expect more than one pass
Clover is a perennial that spreads by stolons rooting at the nodes, so a treatment that only takes the leaves leaves a network behind. Autumn applications move with the plant's own flow of reserves into roots and stolons and reach that network; spring applications frequently burn the top and let it recover. Even done well it usually takes two applications a few weeks apart, and the second is the one that matters.
Check the label for your grass species by name and for a temperature ceiling, and treat when bees are not foraging — clover in flower is actively attracting them, so mow the flowers off first and spray in the evening. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
- Step 5
Overseed whatever you remove, or it comes straight back
Clover dying out leaves gaps, and clover seed is long-lived in soil, so the bare ground is likelier to grow more clover than grass. A fall overseed into the treated areas is what makes the removal stick. Check the herbicide label for its seeding interval first — several broadleaf products require weeks between application and sowing.
- Step 6
To keep it: seed it evenly rather than tolerating patches
Most of what people dislike about clover is the patchiness, not the clover, and that is fixable by sowing it deliberately instead of letting it colonise. Micro-clover is bred for a smaller leaf and a lower, more even habit that blends into turf rather than mottling it. Sow lightly into an existing lawn in spring, and accept that you have given up selective broadleaf herbicide on that lawn — the two are mutually exclusive from then on.

Removing it or keeping it — two different windows
The windows below are timed off frost dates rather than the calendar — the same job happens more than a month apart across the country.
If you are removing it — fall is the effective window
Like dandelion, clover is a perennial moving reserves to its roots and stolons in autumn, and a systemic herbicide moves with them. Spring applications routinely burn the leaves and leave the plant.
| USDA zone | Window |
|---|---|
| Zone 3 | July 21 – September 1 |
| Zone 4 | July 31 – September 11 |
| Zone 5 | August 10 – September 21 |
| Zone 6 | August 25 – October 6 |
| Zone 7 | September 6 – October 18 |
| Zone 8 | September 20 – November 1 |
| Zone 9 | October 10 – November 21 |
| Zone 10 | November 2 – December 14 |
If you are keeping it — overseed clover in spring
Micro-clover and white clover can be sown into an existing lawn in spring. Skip weed preventers on areas you are sowing with clover unless the exact label explicitly permits clover at seeding. Mesotrione products sold for grass seeding, including Tenacity and Scotts Built For Seeding, control clover; grass-seeding permission does not cover clover. If already treated, follow that product's reseeding directions before sowing.
| USDA zone | Window |
|---|---|
| Zone 3 | May 25 – July 6 |
| Zone 4 | May 15 – June 26 |
| Zone 5 | May 5 – June 16 |
| Zone 6 | April 22 – June 3 |
| Zone 7 | April 5 – May 17 |
| Zone 8 | March 20 – May 1 |
| Zone 9 | February 20 – April 3 |
| Zone 10 | January 25 – March 8 |
The windows in each table above are zone-level approximations from long-term freeze normals. A hardiness zone measures winter cold rather than frost dates, so check your own local dates — and where the job is driven by soil temperature, let that have the final say.

Is it bad, why it spreads, and the home remedies
- Is clover bad for my lawn?
- Agronomically, clover is not bad for a lawn — it fixes nitrogen that feeds the surrounding grass, stays green through drought, and was a standard part of lawn seed mixes until selective herbicides made it collateral damage in the 1950s. Whether it is a weed is a preference. The real arguments against it are bees where children play barefoot, staining, and patchiness.
- Why is clover taking over my lawn?
- Clover takes over a lawn almost always because of low nitrogen. Clover makes its own through bacteria in its root nodules, so where the soil is short of it the grass slows and clover does not. Compaction and a pH that blocks nutrient uptake do the same thing indirectly. A soil test checks the pH side, compaction is a probe check, and a single sample may not report nitrogen, so read it with how the lawn has been fed. Feeding the grass properly shifts the balance back without any herbicide.
- How do I get rid of clover in my lawn?
- To get rid of clover, treat in fall with a systemic broadleaf herbicide labeled for your grass, and expect to need a second pass a few weeks later — clover spreads by stolons and one application usually only takes the leaves. Mow the flowers off and treat in the evening so bees are not foraging, then overseed the gaps once the label's seeding interval has passed.
- Will vinegar or dish soap kill clover?
- Vinegar and dish soap burn the clover foliage they touch and leave the roots and stolons, so the clover returns within weeks — and vinegar strong enough to do real damage kills the grass it lands on too and can acidify the soil. Home remedies are non-selective contact treatments being asked to do a systemic selective job. Feeding the grass is the better no-herbicide route.
- Should I plant clover in my lawn on purpose?
- Planting clover on purpose is a reasonable choice, and increasingly a popular one: less fertilizer, better summer color, flowers for pollinators. Sow micro-clover or white clover lightly in spring for an even stand rather than patches. Understand the trade first — you give up selective broadleaf herbicides on that lawn permanently, because they do not distinguish clover from the weeds.

The university extension and public-agency publications listed here back specific statements on this page. Each publication says which statement it backs, so you can check the statement rather than take it on trust. Where a product label or your local extension office disagrees with anything here, follow the label or the extension office.
- Dutch white clover
University of Minnesota Extension
Clover fixes its own nitrogen and feeds pollinators, and a lawn full of it is often one that is low in nitrogen.
- Lawn and Turfgrass Weeds: White Clover
Penn State Extension
If you are removing clover, fall treatment is the effective window, while spring applications often let the plant regrow.
- White Clover in Lawns
UMass Amherst Center for Agriculture, Food, and the Environment
Clover is a nitrogen-fixing legume, and its flowers draw bees, which is one of the real arguments against it where people walk barefoot.
