How to Get Rid of Clover in Your Grass

Getting rid of clover grass in your grass is a common challenge for homeowners across the Sunshine Coast and Gympie regions. While clover might seem like a harmless addition to your turf, it can quickly take over and compromise the quality and appearance of your lawn. Whether you’re dealing with small patches or a widespread infestation, understanding how to effectively remove clover and prevent its return is essential for maintaining top-quality turf that looks consistently beautiful throughout the year.

Understanding Clover

What is Clover?

Clover is a low-growing perennial weed from the legume family, most commonly appearing in Australian lawns as white clover (Trifolium repens). You’ll recognise it by its distinctive three-leafed (sometimes four-leafed) rounded leaves and small white or pink flower heads. Unlike your premium quality turf, clover has a creeping growth habit that spreads rapidly across your lawn through both seeds and stolons (above-ground runners). It’s particularly hardy and can thrive in conditions where grass struggles, making it a persistent problem for lawn owners.

Why it’s a problem in lawns

Clover isn’t just an aesthetic issue – it creates several real problems for your turf. First, it competes directly with your grass for water, nutrients, and sunlight, often winning this battle thanks to its aggressive growth pattern. This competition means your grass blades will struggle to thrive and maintain that lush lawn health you’re after. Clover also disrupts the uniform appearance of your turf, creating patchy, uneven areas that stand out against your quality grass. Its dense mat-like growth can suffocate surrounding grass, preventing proper air circulation and water penetration to the soil beneath. Plus, when clover flowers, it attracts bees, which might be problematic for families with young children or anyone with bee allergies using the lawn.

Common signs of Clover infestation

Spotting clover early makes removal much easier. Look for these telltale signs:

Small patches of bright green, three-leafed plants growing lower than your grass
White or cream-colored spherical flowers appearing from spring through autumn
Dense, mat-like growth that feels different underfoot compared to grass
Areas that stay green during drought or nitrogen deficiency when your grass yellows
Patches that spread rapidly, creating increasingly larger circles or irregular shapes
Plants with shallow root systems that can be easily pulled but return quickly

How Clover Spreads in Lawns

Understanding how clover takes hold helps you combat it more effectively. Clover spreads through multiple methods, making it particularly invasive. Its primary spread mechanism is through stolons – horizontal stems that creep along the soil surface, rooting at nodes to establish new plants. This allows clover to spread quickly across your lawn, even from a single plant.

Clover also produces abundant seeds in those small flower heads. Each flower can produce multiple seeds that remain viable in your soil for years, waiting for the right conditions to germinate. These seeds spread easily through mowing (especially if you mow when flowers are present), foot traffic, birds, and even on the wind.

What makes clover particularly problematic is its ability to fix nitrogen from the atmosphere through a symbiotic relationship with bacteria in its root nodules. This means it can thrive in nitrogen-poor soils where your grass struggles. In fact, clover often appears in lawns with poor soil fertility, compacted soil, or inadequate fertilisation – conditions that weaken your turf and create opportunities for weeds.

Low mowing heights also encourage clover spread. When you scalp your lawn or cut more than 1/3 of the grass height at once, you stress your turf and create gaps where clover can establish. Remember, as with quality turf maintenance, you don’t want to overdo it – regular mowing at the proper height promotes a healthy, strong root system that can better compete with weeds.

Preventing Clover in Lawns

Prevention is always easier than removal. The best defence against clover is maintaining healthy, vigorous turf that naturally outcompetes weeds. Here’s how to keep clover from establishing in the first place:

Maintain proper soil fertility Clover thrives in nitrogen-deficient soils, so regular fertilisation is crucial. Consider our 8-week lawn care programme which provides consistent nutrition to keep your grass strong and competitive. A well-fed lawn will naturally crowd out potential invaders.

Follow proper mowing practices Stick to that important rule of thumb: don’t cut more than 1/3 of the grass height at once. Keep your mower blades sharp for a uniform cut, and maintain the appropriate height for your grass variety. Different varieties and weather conditions need different schedules, but consistency is key. Regular mowing means the healthy grass blades will thrive and weaker ones (and weeds) die out.

Water correctly Deep, infrequent watering encourages deep grass roots that can better compete with shallow-rooted clover. Avoid frequent shallow watering which favours clover establishment.

Improve soil conditions Test your soil pH and adjust if necessary – most premium quality turf prefers slightly acidic conditions (pH 6.0-7.0), while clover tolerates a wider range. Core aeration helps relieve soil compaction, allowing grass roots to penetrate deeper and access nutrients more effectively.

Overseed thin areas Bare or thin patches are invitations for clover. Overseeding these areas with quality grass seed suited to your climate helps maintain dense turf coverage. Here on the Sunshine Coast and in Gympie, we can help you select the right varieties for your conditions.

Apply pre-emergent controls In early spring, before clover seeds germinate, consider applying a pre-emergent herbicide that prevents seed germination without harming established grass.

Removing Clover from Lawns

If clover has already established in your lawn, don’t worry – several effective removal methods exist. The best approach often combines multiple techniques.

Manual removal for small infestations

For isolated patches or early-stage infestations, manual removal can be highly effective. Water your lawn the day before to soften the soil, making removal easier. Using a weeding tool or your hands (gloves recommended), grasp the clover at its base and pull gently but firmly, trying to remove as much of the root system and stolons as possible. Be thorough – any fragments left behind can regenerate. After removing clover, fill the bare spots with quality topsoil and overseed to prevent reinfestation.

Organic methods

Vinegar solution: A natural herbicide, household vinegar (5% acetic acid) or horticultural vinegar (20% acetic acid – handle with care) can kill clover. Apply directly to clover on a sunny day, avoiding surrounding grass as much as possible. You’ll likely need multiple applications. This works best on young clover plants.

Corn gluten meal: Applied in early spring, this natural pre-emergent prevents clover seeds from germinating. It won’t affect established clover but helps prevent new infestations.

Smothering: For large patches, cover the clover with cardboard or thick newspaper, then top with mulch or soil. After several weeks, the clover will die from lack of sunlight. You can then plant new grass.

Selective herbicides

For widespread infestations, selective broadleaf herbicides offer the most efficient solution. Products like Bow and Arrow are specifically designed to target broadleaf weeds including clover while leaving your grass unharmed. These herbicides work by disrupting the growth hormones in broadleaf plants.

Application tips:

Apply when clover is actively growing (spring and autumn are ideal)
Choose a calm, dry day with no rain forecast for 24-48 hours
Avoid applying when temperatures exceed 28°C as this can stress your grass
Water your lawn 2-3 days before application so plants aren’t drought-stressed
Don’t mow for 2-3 days before or after application to maximise absorption
Follow product instructions precisely regarding mixing rates and application methods
Be patient – it can take 2-3 weeks to see full results
Multiple applications may be necessary for established infestations

Always read and follow label directions carefully. If you’re unsure about application, our team at Roberts Turf Supplies is happy to provide guidance.

Combination approach

For best results, especially with moderate to severe infestations, combine methods. Start with a selective herbicide application to knock back the majority of the clover. As it dies off, manually remove any remaining patches. Then, focus on prevention strategies to ensure clover doesn’t return. This comprehensive approach addresses both existing plants and the conditions that allowed clover to establish.

Post-Removal Lawn Care

Once you’ve removed clover, proper follow-up care is essential to help your turf recover and prevent reinfestation. Think of this as giving your lawn equal access to the sun and water it needs to flourish.

Overseed bare patches: Clover removal often leaves gaps in your turf. Fill these with appropriate grass seed for your lawn type and climate. In the Sunshine Coast and Gympie regions, we can recommend turf varieties that will thrive in your specific conditions.

Fertilise strategically: Apply a balanced fertiliser to give your recovering grass a boost. This helps grass quickly fill in areas where clover grew, preventing new weeds from establishing. Remember, strong, healthy grass is your best defence.

Maintain consistent watering: Newly seeded areas need regular moisture to germinate and establish. Water lightly but frequently until new grass is established, then return to deep, infrequent watering.

Resume proper mowing: Once your grass has recovered and new growth is established, return to your regular mowing routine. Keep blades sharp for that uniform cut, and maintain appropriate height for your grass variety. This promotes lush lawn health and helps combat pests and keep weeds away.

Monitor closely: Keep an eye out for clover returning. Early detection makes control much easier. If you spot new clover plants, remove them immediately before they spread.

Consider professional support: If you’re starting fresh or need expert guidance, our professional lawn services include turf installation and maintenance advice tailored to Sunshine Coast conditions.

Common Mistakes to Avoid

Even with the best intentions, homeowners often make mistakes that either reduce treatment effectiveness or create conditions for clover to return:

Scalping your lawn: This is perhaps the biggest mistake. Never remove more than 1/3 of the grass blade length at a time, even if your lawn has become overgrown. If it’s too tall, you’ll need to mow in stages. Scalping stresses your turf, creates bare patches, and makes life harder for yourself.

Applying herbicides incorrectly: Using too much herbicide can damage your grass, while too little won’t effectively control clover. Spraying in windy conditions, extreme heat, or before rain reduces effectiveness. Always follow product instructions precisely.

Neglecting soil health: Removing clover without addressing the underlying soil conditions (low nitrogen, compaction, poor pH) means it’ll likely return. Healthy soil grows healthy grass that naturally resists weeds.

Inconsistent treatment: Spot-treating clover here and there without a comprehensive approach rarely works. Clover spreads quickly, so partial treatment just delays the inevitable.

Mowing clover flowers: If clover has flowered, mowing spreads seeds throughout your lawn, potentially worsening the problem. Remove or treat clover before it flowers, or collect clippings if flowers are present.

Ignoring small patches: That tiny bit of clover won’t stay tiny. Early intervention is far easier than dealing with a widespread infestation later.

Over-watering: Frequent shallow watering favours clover over grass. Deep, infrequent watering builds stronger grass roots that better compete with weeds.

Poor timing: Treating dormant clover or applying products in unsuitable weather conditions wastes time and money without achieving results.

FAQs About Clover in Lawns

Is clover always bad for lawns? While some people intentionally plant clover for its nitrogen-fixing abilities and drought tolerance, in a traditional turf lawn it’s generally considered a weed. It disrupts uniformity, can overtake grass, and attracts bees which may be unwanted. For most homeowners seeking quality turf, clover removal is desirable.

How quickly can clover take over a lawn? Under favourable conditions, clover can spread rapidly. A single plant can cover several square metres in one growing season through its creeping stolons. Seed production is also prolific, with plants potentially producing hundreds of seeds annually.

Can I prevent clover without chemicals? Yes! Maintaining healthy, vigorous grass through proper fertilisation, mowing, and watering is the most effective natural prevention. Dense, well-maintained turf naturally resists clover invasion. Manual removal of small patches also works well as a chemical-free option.

Will clover go away on its own? Unfortunately, no. Once established, clover persists and spreads unless actively managed. It won’t disappear without intervention.

What grass varieties resist clover best? Dense-growing varieties that create thick turf coverage resist clover most effectively. However, the key isn’t the grass variety itself but rather maintaining healthy, vigorous growth through proper care. Any quality turf, when well-maintained, will outcompete clover.

How long after herbicide application can children and pets use the lawn? This varies by product. Most selective herbicides require waiting until the spray has dried (typically 2-4 hours) before allowing access. Always check the specific product label for guidance. If you’re concerned, manual removal methods avoid this issue entirely.

Why does clover appear in well-maintained lawns? Even well-maintained lawns can develop small areas of poor fertility, compaction, or other stress factors that create opportunities for clover. Seeds can also blow in from neighbouring properties or remain dormant in soil for years before germinating.

Final Thoughts

Removing clover grass from your lawn requires a combination of effective control methods and ongoing prevention strategies. Remember, you might start with premium quality turf, but maintaining it requires consistent care and attention. By understanding why clover establishes, how it spreads, and what conditions favour its growth, you’re better equipped to keep your lawn clover-free.

The key to long-term success is creating conditions where your grass thrives and clover struggles. This means regular fertilisation to maintain nitrogen levels, proper mowing practices that promote healthy root systems, appropriate watering schedules, and quick action when problems arise. Don’t let small infestations become major ones – address clover as soon as you spot it.
