How to Get Rid of Clover in Your Lawn (Without Killing Your Grass)
If white clover is spreading across your Ohio lawn, you're not alone — it's one of the most common weeds we treat. The good news: clover is very beatable once you understand why it showed up in the first place. Here's how to identify it, remove it, and keep it from coming back.
Why clover shows up in Ohio lawns
Clover doesn't invade healthy lawns by accident — it moves in where grass is struggling. In Northeast Ohio, we see the same three triggers over and over:
- Low nitrogen soil — clover makes its own nitrogen, so it thrives where under-fertilized grass can't.
- Compacted soil — heavy clay soils common in Ohio compact easily, stressing grass roots but not clover.
- Mowing too short — scalped grass can't shade the soil, giving low-growing clover all the sunlight it wants.
How to identify clover
White clover (Trifolium repens) is the usual suspect in Ohio yards. Look for the classic three-oval-leaf clusters, small white (sometimes pink-tinged) globe flowers in late spring, and stems that creep along the ground and root at the nodes — which is why patches spread outward in circles year after year. You may also spot bees working the flowers in June and July.
5 proven ways to remove clover
1Hand-pull small patches
For a few scattered patches, pulling works — but get the whole creeping stem and root nodes, not just the leaves. Water the area first so the soil releases roots easily, then reseed any bare spots so clover can't reclaim them.
2Feed your lawn nitrogen
This is the real long-term fix. A properly fertilized lawn outcompetes clover because grass finally has the nitrogen it was missing. Plan on a regular fertilization schedule — in Ohio, spring and fall feedings matter most.
3Raise your mowing height
Keep grass at 3 to 3.5 inches. Taller grass blades shade the soil, and clover hates shade. This single change slows clover dramatically and costs nothing.
4Spot-treat with a post-emergent herbicide
For larger infestations, a selective broadleaf herbicide labeled for clover will kill it without harming turfgrass. Apply when clover is actively growing (spring or early fall), follow the label exactly, and expect a second pass for mature patches.
5Aerate compacted areas
Core aeration in the fall relieves the compaction that favors clover, lets fertilizer actually reach grass roots, and sets your lawn up to crowd clover out the following season.
What NOT to do
- Don't scalp your lawn hoping to mow the clover away — you'll stress the grass and help the clover.
- Don't reach for a non-selective weed killer — it kills clover and everything around it, leaving bare soil for new weeds.
- Don't treat once and forget it — without fixing nitrogen levels and compaction, clover returns every season.
DIY vs. professional weed control
Hand-pulling and mowing higher are great weekend wins for small patches. But when clover covers a third of your yard, keeps returning after treatment, or you simply don't have the time, a professional weed control program is usually cheaper than repeated DIY attempts. At Four Seasons Lawn & Landscape, our weed control visits pair targeted treatment with the fertilization your lawn needs to keep clover out for good — not just knock it back for a month.
Frequently asked questions
Is clover bad for my lawn?
Clover isn't harmful, but it competes with grass, looks patchy, and attracts bees — a concern for kids and pets playing barefoot. It also spreads fast, so small patches rarely stay small.
Why does clover keep coming back?
Clover thrives in soil that's low in nitrogen and compacted — conditions grass struggles in. Unless you fix the underlying soil health and fertilization, clover will return year after year.
When is the best time to treat clover in Ohio?
Early spring and early fall are ideal in Ohio. Clover is actively growing and pulling nutrients, so treatments absorb better. Fall treatment also weakens it before winter dormancy.
Will mowing shorter get rid of clover?
No — scalping your lawn actually helps clover win. Mowing higher (3 to 3.5 inches) lets grass shade out low-growing clover and is one of the easiest long-term fixes.
