White Clover: identify it, treat it, keep it out
White clover is a low, creeping perennial legume with the classic three-leaflet shape and white pom-pom flowers. It thrives exactly where grass struggles, in low-nitrogen soil, because it fixes its own nitrogen. Heavy clover is usually a message that the lawn is underfed.
How to identify white clover
- Three round leaflets, often with a pale crescent watermark
- White to pinkish globe flowers from late spring through summer that draw bees
- Creeping stems (stolons) that root at nodes and form expanding patches
- Stays green through drought that browns the surrounding grass
Don't confuse it: Oxalis (wood sorrel) has similar trifoliate leaves but they are heart-shaped and it has small yellow flowers.

When to treat
Treatment (post-emergent)
Best time: Spring or fall
Target stage: Actively growing
Conditions: Apply when weeds are dry · No rain for 24 hours · Temps 60-75°F
Germination starts around 45°F soil temperature (optimal 60°F). Track your ZIP's live soil temperature or get an exact plan from the herbicide timing calculator.
Control plan
- 1Increase nitrogen fertilization to outcompete clover
- 2Use selective herbicides in spring or fall
- 3Improve lawn density through proper care
- 4Consider that clover can be beneficial to soil health
Good to know
- • Fixes nitrogen, can actually benefit soil
- • Indicates low nitrogen in soil
- • Can be controlled with selective herbicides
- • Often appears in thin or stressed lawns

Frequently asked questions
Should I even remove clover?
Not necessarily. Clover feeds itself and neighboring grass with fixed nitrogen, stays green in drought, and supports pollinators. Many owners now overseed micro-clover deliberately. Remove it only if you want a uniform pure-grass stand.
Why is clover taking over my lawn?
Low soil nitrogen. Grass starves while clover feeds itself, so clover wins thin, hungry lawns. A regular fertilization program shifts the advantage back to grass and often shrinks clover on its own.
What kills clover without killing grass?
Selective broadleaf herbicides with triclopyr or fluroxypyr work well; standard 2,4-D alone is weak on clover. Fall application is most effective, and bagging clippings for a few mows afterward limits re-rooting of stolon fragments.
