Eliminating Clover from Your Lawn

Effective Clover Control in Ontario Lawns

Clover spreads by seed and creeping stems. To stop its expansion, prevent flowering and seed drop. For active eradication, use selective herbicides.

Herbicide Options

• Broadleaf formulas: Products containing 2,4-D, dicamba (Trimec, Confront), MCPA, or bentazone (e.g., Weed-B-Gon).
• Iron-based: Ferrous sulfate (contact action) burns clover foliage.
• Spot treatment for dense patches: Glyphosate (Roundup) kills all vegetation; reseed afterward.

Cultural Suppression

Maintain a dense, fertilized lawn (1–3 inches water/week, proper mowing). Healthy turf outcompetes clover. Also, grubs under clover roots are coincidental—treat grubs separately if needed.

Consistent herbicide use plus good cultural practices will reduce clover over time.
