What kills clover but not grass?

Spot‑spray triclopyr (e.g., Ortho Chickweed, Clover & Oxalis Killer) or mesotrione (Tenacity). Both are selective on most turfgrasses. Apply to actively growing clover, add surfactant if the label allows, and avoid heat stress days. Follow up with overseeding once the patch thins.

Will fertilizer alone get rid of clover?

Sometimes. Clover thrives in low‑nitrogen soils. Feeding 0.5–1.0 lb N/1,000 sq ft and mowing 3–4 inches can reduce clover over 3–6 weeks. For moderate to heavy infestations, pair feeding with a triclopyr or mesotrione spot‑spray to speed results and prevent reseeding.

When is the best time to spray clover?

Cool, moist weather in spring or early fall, when clover is actively growing. Avoid drought stress and heat (>85°F). Don’t mow 1–2 days before or after spraying. If rain is forecast, choose a product with a short rainfast window and follow the label.

Can I reseed after using clover killer?

Yes, but timing depends on the product. Triclopyr usually requires a 2–3 week wait before seeding (check your label). Mesotrione (Tenacity) often allows seeding sooner and is commonly used at seeding. Always read the specific reseeding interval on the label.

Is clover bad for my lawn?

Clover isn’t inherently harmful; it fixes nitrogen and stays green in summer. But it signals low fertility and can outcompete thin turf. If you want a uniform grass look, improve fertility, mow high, and spot‑control clover—then overseed to keep density high.

How to Get Rid of Clover in Lawn without Wrecking It

Clover in your lawn? Don’t panic

We like clover in pastures. In lawns, most folks don’t. Good news: clover is beatable without carpet‑bombing your turf. It’s mostly a soil fertility and density problem. Feed the grass, trim smarter, surgically spot‑spray, and overseed. Two to four weekends and you’ll forget it was there.

Why clover shows up (and why killing it isn’t step one)

Clover loves low‑nitrogen, thin turf. If you only spray, it returns. We fix the root cause first: feed the lawn and thicken it. Clover stops volunteering once the grass is fed and casting shade.

Here’s the stat most people miss. Most cool‑season lawns perform best with 2–3 lb of nitrogen per 1,000 sq ft per year, split into 2–4 feedings. Individual applications should be 0.5–1.0 lb N/1,000 sq ft (source: University of Minnesota Extension: https://extension.umn.edu/lawn-care/fertilizing-lawns).

Quick plan that works (our field routine)

Week 0: Mow high (3–4 inches). Taller grass = less light for clover.
Feed: Apply 0.5–0.75 lb N/1,000 sq ft with a slow‑release fertilizer (30%+ slow‑release is ideal). Water in 0.25–0.5 inch if no rain.
Week 1–2: Spot‑spray only the clover patches with a clover‑capable selective herbicide (details below). Don’t broadcast if 90% of what you see is grass.
Week 2–3: Rake out dead clover, loosen top 1/4 inch of soil, and overseed thin spots with a matching grass blend. Keep seed moist for 10–14 days.
Weeks 4–6: Repeat spot‑spray on any survivors per label, then resume normal mowing/feeding.

We’ve knocked down 30% clover coverage to near 0% in two weeks using that playbook on cool‑season lawns, with minimal turf stress.

Products that actually smoke clover (and what they cost)

Ortho Weed B Gon Chickweed, Clover & Oxalis Killer (triclopyr): $9–$12 RTU, $15–$25 concentrate. Triclopyr reliably curls clover without nuking grass.
Tenacity Herbicide (mesotrione): ~$60–$70 for 8 oz. Slower, causes temporary whitening; safe on most cool‑season grasses. Great for mixed weed pressure.
SpeedZone Lawn Weed Killer (2,4‑D + dicamba + MCPP + carfentrazone): ~$45–$55 per quart. Fast top‑burn; strong on clover. Use carefully; follow label.
Fiskars Xact Weeder: ~$32–$38. For small patches, yank the crown + roots and skip chemicals.

Avoid non‑selective sprays (glyphosate) unless you enjoy reseeding rectangles. Also skip “general weed and feed” for clover—most lack enough punch, and timing rarely matches when clover is actively growing.

Spot‑spray vs broadcast (and when timing matters)

Spot‑spray: Use for patches under 25–30% of the lawn. Less collateral stress, cheaper, and you can reseed sooner.
Broadcast: Only if clover dominates. If you must, pick triclopyr or a 3‑ or 4‑way with triclopyr and expect to overseed 2–4 weeks later (check label).
Best timing: Cool, moist conditions with clover actively growing. Spring or early fall beats mid‑summer scorch.

Pro tip: Add a non‑ionic surfactant (per label) to help the spray stick to clover’s waxy leaves.

Natural and kid/pet‑forward options

Iron‑based weed killers (FeHEDTA), like Fiesta, blacken clover quickly. They’re less consistent on mature patches but safer around play areas. Expect repeats.
Fertility + mowing high: Feeding 0.5 lb N/1,000 sq ft and mowing 3–4 inches often thins clover by itself in 3–6 weeks.
Hand removal: After rain, pry the crown and as much root as possible. Fill divots with soil + seed.

If you’d rather coexist, microclover can be blended into turf for a low‑input, green‑all‑summer look. But this article’s about eviction, not adoption.

Keep clover from coming back (maintenance that sticks)

Feed on a schedule: Aim for 2–3 lb N/1,000 sq ft/year, anchoring 1 lb in early fall.
Mow high: 3–4 inches keeps light off clover seedlings.
Water deeply, not daily: 1 inch/week in one or two soakings. Shallow watering favors weeds.
Overseed thin areas every fall. Density is weed insurance.
Use pre‑emergents for other pests like crabgrass so you’re not splitting focus. See our full plan: How to Get Rid of Crabgrass Permanently.

Troubleshooting look‑alikes and other lawn issues

Not every three‑leaf invader is clover. Oxalis (yellow wood sorrel) and black medic look similar but respond to the same triclopyr/mesotrione routine. If your lawn has dead patches or off‑season browning, rule out pests and disease before spraying:

What we skip (so you don’t waste time)

Corn gluten meal as a “pre‑emergent” for clover. White clover is a perennial—pre‑emergents don’t remove established plants.
Blanket spraying the whole yard “just because.” Target, then seed. Your grass (and wallet) will thank you.
