How to Get Rid of Clover in Lawn: A Complete Guide

Clover, with its distinctive three-leaf clusters and small white or pink flowers, can quickly transform your lush green lawn into a patchy, uneven mess. While some gardeners appreciate clover for its nitrogen-fixing properties, it’s a common lawn weed that competes with grass for nutrients, water, and sunlight, often leading to a less-than-perfect yard. Knowing how to get rid of clover in lawn is crucial for homeowners who want a pristine, clover-free lawn. Its aggressive spreading habit and resilience make it a challenge, but with the right strategies, you can eliminate clover and prevent its return. This comprehensive guide covers everything from identifying clover to effective removal methods and prevention tips, ensuring your lawn stays healthy and vibrant. Let’s dive into lawn weed control for clover and reclaim your yard.

What is Clover?

Clover (Trifolium spp.) is a low-growing, perennial broadleaf weed commonly found in lawns across North America and beyond. Belonging to the legume family, clover is known for its ability to fix nitrogen in the soil, which can benefit nearby plants but also makes it a vigorous competitor in lawns. Common species include white clover (Trifolium repens), red clover (Trifolium pratense), and alsike clover (Trifolium hybridum). White clover, with its small white flowers and creeping stems, is the most frequent culprit in lawns.

Key Characteristics:

• Leaves: Three (sometimes four) oval leaflets with a white “V” or crescent mark on each.
• Flowers: Small, round clusters of white or pinkish flowers, blooming spring through fall.
• Growth Habit: Spreads via creeping stems (stolons) that root at nodes, forming dense patches.
• Root System: Shallow, fibrous roots with nodules that fix nitrogen, aiding its survival.

While clover can improve soil fertility, its patchy growth and ability to choke out grass make it undesirable for those seeking a uniform lawn.

How to Identify Clover in Lawn

Identifying clover in your lawn is straightforward, but distinguishing it from similar weeds like oxalis or medic ensures you target the right plant. Here’s how to spot clover:

• Leaves: Look for clusters of three leaflets, each with a white, chevron-shaped marking. Leaves are smooth, not hairy.
• Flowers: Small, globe-like white or pink flowers on short stalks, blooming from late spring to early fall.
• Growth Pattern: Forms dense, mat-like patches that spread outward, often crowding out grass.
• Location: Thrives in sunny to partially shaded areas, especially in nitrogen-poor or compacted soils.

Pro Tip: Unlike oxalis (false shamrock), which has heart-shaped leaves and yellow flowers, clover’s leaflets are more rounded, and its flowers are white or pink. Check for clover in spring and summer when it’s actively growing.

Causes of Clover Growth in Lawns

Clover thrives in lawns due to conditions that give it a competitive edge over grass. Understanding these causes helps you address the problem effectively:

• Low Nitrogen Levels: Clover’s nitrogen-fixing ability allows it to thrive in nutrient-deficient soils where grass struggles.
• Compacted Soil: Hard, compacted soil limits grass growth but doesn’t faze clover’s shallow roots.
• Improper Mowing: Mowing too low weakens grass, creating openings for clover to spread.
• Inconsistent Watering: Over- or under-watered lawns stress grass, leaving room for clover to invade.
• Poor Lawn Health: Thin or sparse grass from neglect or drought creates ideal conditions for clover.

By correcting these issues, you can make your lawn less hospitable to clover and improve lawn maintenance after clover treatment.

How to Get Rid of Clover in Lawn

Eliminating clover requires a targeted approach to tackle its spreading stolons and nitrogen-fixing roots. Below are three effective methods—manual removal, organic solutions, and chemical herbicides—to suit different preferences, including natural ways to get rid of clover and faster chemical options.

Manual Removal

Hand-pulling or digging out clover is a labor-intensive but eco-friendly option, ideal for small infestations or those preferring organic methods to remove clover.

• Tools Needed: Garden fork, trowel, or weeding tool (e.g., CobraHead Weeder).
• Steps:
  • Water the lawn to soften the soil, making roots easier to pull.
  • Use a tool to dig around the clover, extracting as much of the root system and stolons as possible.
  • Dispose of clover to prevent rerooting, and fill holes with soil or grass seed.
• Pros: Chemical-free, immediate results, cost-effective.
• Cons: Time-consuming; missed roots or stolons can lead to regrowth.

Tip: Pull clover before it flowers to prevent seed spread. Regular monitoring is key for controlling clover in lawn naturally.

Organic Solutions

For environmentally conscious homeowners, natural ways to kill clover offer safe, pet- and kid-friendly options:

• Vinegar Spray: Mix horticultural vinegar (20% acetic acid) with a drop of dish soap. Spray on clover leaves on a sunny day to burn foliage. Household vinegar (5%) works for young plants but may need repeat applications.
• Corn Gluten Meal: Apply this natural pre-emergent in early spring (10–20 lbs per 1,000 sq ft) to inhibit clover seed germination. It also fertilizes grass, boosting lawn health.
• Smothering: Cover clover patches with black plastic, cardboard, or heavy mulch for 4–6 weeks to block sunlight and kill the plant.
• Boiling Water: Pour over clover in non-lawn areas (e.g., driveways) to scald leaves and roots. Less effective for large lawn infestations.

Pros: Safe for the environment, supports organic methods to remove clover.

Cons: May require multiple treatments; less effective on mature clover.

Chemical Herbicides

For widespread clover or stubborn patches, chemical herbicides provide fast, effective control. Here’s how to choose the best herbicide for clover:

• Selective Herbicides: Products containing 2,4-D, dicamba, or MCPP (e.g., Ortho Weed B Gon) target broadleaf weeds like clover without harming grass. Apply on a calm, dry day per label instructions.
• Non-Selective Herbicides: Glyphosate (e.g., Roundup) kills clover and grass, so use it for spot treatments in non-lawn areas. Re-seed after 7–10 days.
• Application Tips:
  • Use a pump sprayer for even coverage.
  • Apply when clover is actively growing (spring/early summer).
  • Avoid mowing for 2–3 days post-application to maximize absorption.

Pros: Quick results, ideal for large infestations.

Cons: May harm beneficial plants or pollinators if misapplied; follow safety guidelines.

Best Time of Year to Remove Clover

Timing is critical for effective clover removal. The best periods are:

• Early Spring: Clover is actively growing but hasn’t yet flowered, making it easier to control before seeds form. Corn gluten meal works well as a pre-emergent now.
• Early Summer: Young clover is more susceptible to herbicides or vinegar sprays. Avoid treating during hot, dry periods when plants are stressed and less responsive.
• Fall: A secondary window for spot treatments, as clover prepares for dormancy but is still active.

Avoid removal during peak summer heat or winter dormancy, as clover may not respond well to treatments. Regular lawn maintenance after clover treatment helps prevent regrowth.

Prevention Tips to Avoid Clover Regrowth

Once you’ve eliminated clover, keep it at bay with these proactive steps:

• Fertilize Regularly: Apply a nitrogen-rich lawn fertilizer (e.g., 16-20-0 NPK) in spring and fall to strengthen grass, reducing clover’s advantage.
• Mow Properly: Set your mower to 3–3.5 inches to promote dense grass growth, shading out clover seedlings.
• Aerate Annually: Core aeration reduces soil compaction, improving grass health and limiting clover’s foothold.
• Water Consistently: Provide 1–1.5 inches of water weekly to keep grass vigorous without overwatering, which favors clover.
• Overseed Thin Areas: Plant fast-growing grass varieties (e.g., tall fescue or perennial ryegrass) in bare spots to crowd out clover.
• Monitor Regularly: Check for clover weekly during growing season to catch new growth early.

Conclusion

Learning how to get rid of clover in lawn empowers you to restore your yard’s beauty and health. Whether you choose manual removal, organic solutions like vinegar or corn gluten meal, or the best herbicide for clover, a targeted approach ensures success. Pair removal with prevention tactics—proper fertilization, mowing, and aeration—to keep clover at bay for good. With persistence and the right strategy, your lawn can be clover-free and thriving.
