I used to spend far too many frustrating hours every weekend wrestling weeds out of my beloved zoysia. Seriously, identifying the absolute best weed control for zoysia grass became my personal, obsessive mission. After countless experiments, I finally uncovered some truly effective products worth your attention. I am genuinely excited to share my hard-won, honest experiences with you now.
1. Scotts Liquid Turf Builder with Plus 2 Weed and Feed
When my Zoysia needed a quick pick-me-up while simultaneously battling widespread broadleaf weeds, this liquid combination product became a regular in my arsenal. The convenience of a hose-end sprayer is undeniable, especially when covering larger areas where granular spreaders can be finicky around obstacles. It’s a straightforward approach to lawn care that promises both nourishment and weed elimination.
Key Features:
– Fertilizes in 24 hours while controlling for weeds: This means your lawn gets a quick nutrient boost, encouraging healthy growth to outcompete emerging weeds.
– Kills dandelions, clover and other major lawn weeds: It effectively targets a wide range of common broadleaf nuisances that often plague Zoysia lawns.
– Other weeds include buckhorn, chickweed, ground ivy, henbit, knotweed, lambsquarters, oxalis, pigweed, plantain, poison ivy, ragweed, and spurge: This broad spectrum coverage reduces the need for multiple specialized products for different weed types.
– Easy to use, simply attach hose and spray: The ready-to-spray design simplifies application, saving time and eliminating the need for mixing or complex equipment.
– Spray when weeds are actively growing: This ensures the herbicide is absorbed effectively by the weeds, maximizing its killing power.
Performance & Real-World Use
I found this product particularly useful for spring applications when both weeds were actively growing and the Zoysia was waking up and needed feeding. The hose-end sprayer delivers a consistent pattern, and I noticed dandelions and clover beginning to wilt within a few days. The Zoysia itself responded with a noticeable green-up, indicating the fertilizer was working as intended. Coverage was generally even across the lawn.
Pros:
– Convenient Application: The hose-end sprayer makes it incredibly simple to apply evenly across the lawn without extra mixing.
– Dual Action: It feeds the lawn while killing weeds, promoting a dense turf that naturally resists future weed invasion.
– Broadleaf Control: Effectively tackles a long list of common broadleaf weeds that plague Zoysia.
– Quick Green-Up: The fertilizer component delivers rapid visible results in lawn health and color.
Cons:
– No Crabgrass Control: This product is designed for broadleaf weeds and will not address crabgrass issues.
– Weather Dependent: Optimal results require application during specific temperature ranges and when weeds are actively growing.
– Limited Control on Established Tough Weeds: While effective, very mature or deeply rooted weeds might require a second application or a more potent solution.
Who Should Buy This: This is an excellent choice for the homeowner seeking a convenient, all-in-one spring or fall application to tackle common broadleaf weeds while simultaneously boosting Zoysia health. It suits those who prefer liquid applications and value ease of use over specialized weed control.
My Verdict: For straightforward broadleaf control and a quick fertilization boost, this is a solid performer. Its ease of use makes it a go-to for general lawn maintenance, though it won’t solve all your weed problems. I rate it a strong 7.5/10 for its specific utility.
2. Scotts Turf Builder Weed and Feed 3, 5,000 sq. ft.
When a more aggressive stance against widespread dandelions and clover was required, I often reached for the granular Weed and Feed 3. This isn’t just about general feeding; it’s engineered with a focus on eliminating those notoriously stubborn broadleaf weeds that can quickly take over a Zoysia lawn. It offers a powerful combination for both eradication and turf strengthening.
Key Features:
– Up to 2X more powerful dandelion and clover control (vs. previous formula): This means it delivers a significantly stronger punch against two of the most pervasive broadleaf weeds.
– Clears out dandelions and clover—satisfaction guaranteed: This provides confidence in its ability to effectively remove these specific and common broadleaf weeds.
– Weedgrip Technology grips the weeds you see—and the ones you don’t: This innovative technology ensures the granules stick to weed foliage, enhancing absorption and effectiveness.
– Scotts most powerful weed and feed: This indicates it’s designed for maximum impact when facing significant broadleaf weed infestations alongside turf feeding.
– Feeds to thicken lawns and crowd out weeds: By promoting dense Zoysia growth, it creates a healthier turf that naturally suppresses future weed germination.
Performance & Real-World Use
I applied this granular product with a broadcast spreader after a light dew or rain, ensuring the granules would adhere to the weed foliage, as recommended. Within a week, the dandelions and clover showed clear signs of stress, yellowing and shriveling. The Zoysia grass, after a couple of weeks, exhibited a deeper green and noticeably thicker appearance. This product genuinely delivered on its promise of powerful weed control alongside turf nourishment.
Pros:
– Enhanced Dandelion/Clover Control: Clearly superior to many general products for these specific, common broadleaf weeds.
– Weedgrip Technology: Improves contact with weed leaves, leading to better absorption and kill rates.
– Thickens Lawn: The feeding aspect helps Zoysia become denser, crowding out new weed growth.
– Granular Application: Preferred by some for its controlled spread and less drift than liquid sprays.
Cons:
– Requires Wet Foliage: For optimal results, weeds must be damp for granules to stick, which can dictate application timing.
– No Crabgrass Control: Similar to other Weed & Feed products, it does not target grassy weeds like crabgrass.
– Temperature Sensitivity: Best applied when temperatures are consistently within the recommended range, which can limit application windows.
Who Should Buy This: This product is ideal for Zoysia owners battling a noticeable presence of dandelions and clover who also want to give their lawn a significant feeding boost. It suits those comfortable with granular spreaders and appreciate a satisfaction guarantee for weed control.
My Verdict: If dandelions and clover are your primary broadleaf headache, this is a potent solution. The Weedgrip technology is a real differentiator, and the feeding action is solid. A very effective choice for its specific purpose. I rate it 8/10.
3. Ortho WeedClear Lawn Weed Killer Ready-To-Spray – Kills Crabgrass, Dandelion
When facing a mixed bag of both broadleaf weeds and particularly aggressive grassy weeds like crabgrass in my Zoysia, this Ortho WeedClear solution often proved its worth. The convenience of a ready-to-spray hose attachment meant I could quickly and efficiently cover large areas, addressing multiple weed types without needing to swap products. It’s designed for direct, fast-acting treatment.
Key Features:

– WHERE TO USE: This spray weed killer for lawns won’t harm lawn grasses when used as directed – use on lawn grasses including Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass and Zoysiagrass: Explicitly stating Zoysiagrass compatibility provides peace of mind that your lawn will be safe.
Performance & Real-World Use
I found this product to be a reliable workhorse against a variety of weeds. The hose-end sprayer provided good coverage, and I saw noticeable wilting in broadleaf weeds within 24-48 hours, with crabgrass taking a few days longer to show significant decline. Importantly, my Zoysia remained unharmed when applied according to directions, even during warmer temperatures. It’s a quick, no-fuss solution for a common problem.
Pros:
– Broad-Spectrum Control: Effectively kills both broadleaf weeds (dandelion, clover) and grassy weeds (crabgrass, foxtail), which is a major advantage.
– Zoysia Safe: Formulated to be safe for Zoysia grass when used as directed, preventing unwanted turf damage.
– Fast-Acting: Provides visible results quickly, which is satisfying when tackling an infestation.
– Convenient Application: Ready-to-spray design eliminates mixing and mess, making application simple and efficient.
Cons:
– No Fertilization: Unlike “Weed and Feed” products, this is purely a weed killer, so separate fertilization is needed.
– Requires Even Application: Inconsistent spraying can lead to missed spots or over-application in others, potentially causing uneven results.
– Limited Residual Control: Primarily a post-emergent killer, it won’t prevent new weeds from sprouting long-term.
Who Should Buy This: This is an excellent choice for Zoysia homeowners dealing with a combination of broadleaf and grassy weeds, particularly crabgrass, who prioritize a fast-acting, convenient, and Zoysia-safe liquid solution. It’s for those needing targeted weed elimination without a feeding component.
My Verdict: For a truly versatile post-emergent that effectively tackles both broadleaf and grassy weeds like crabgrass without harming Zoysia, this Ortho product is a standout. It’s incredibly practical. I rate it 9/10 for its broad utility.
4. Scotts Turf Builder Weed and Feed5 – Kills & Feeds
When my Zoysia lawn needed a substantial feed along with comprehensive broadleaf weed control, this granular Weed and Feed5 formula was a strong contender. It offers a robust dual-action approach, aiming not just to eliminate existing weeds but to encourage a thick, healthy turf that naturally crowds out future invaders. This particular formulation boasts control over a wide array of weeds.
Key Features:
– WEED AND FEED FOR LAWNS: Apply this combination weed killer for grass and lawn food to your wet lawn when weeds are actively growing and daytime temperatures are consistently between 60°F and 90°F; don’t apply more than 2X per year: This provides crucial guidance on optimal application timing for maximum effectiveness and turf safety.
– WEED KILLER PLUS LAWN FOOD: Scotts Turf Builder Weed & Feed5 weed killer plus fertilizer for grass is a clover and dandelion killer for lawns that also feeds to thicken your lawn and crowd out future weeds: This explains the core benefit of promoting a dense, weed-resistant lawn through nutrition and elimination.
– DO NOT USE ON: Do not use this grass fertilizer for lawns plus yard weed killer on St. Augustinegrass (including Floratam), Dichondra, Lippia, Carpetgrass, and Bentgrass lawns: This explicitly lists incompatible grasses, preventing accidental damage to sensitive turf types.
– USE ON LISTED GRASS TYPES: Apply this lawn care product to Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass: Confirming Zoysiagrass compatibility gives confidence in its safe application on your lawn.
– WEED CONTROL FOR LAWNS: These Scotts weed killer plus lawn fertilizer granules control over 50 listed lawn weeds, including clover, dandelion, plantain, morningglory, chicory, eveningprimrose, and purslane: This highlights its extensive broadleaf weed killing capability, making it a comprehensive solution.
Performance & Real-World Use
I used this product during the peak growing season, ensuring the grass was damp before application to help the granules stick. Within a week, the broadleaf weeds like clover and plantain started to shrivel and die, making a noticeable difference. The Zoysia gradually became richer in color and density, clearly benefiting from the fertilizer. It’s a reliable, thorough solution for broadleaf weed infestations when conditions are right.

7. Scotts Turf Builder Liquid Lawn Food Plus Weed Control
When I needed a fast, convenient way to give my Zoysia a quick feed and knock back common broadleaf weeds without the hassle of a granular spreader, this liquid Scotts Turf Builder was a reliable choice. The hose-end application is straightforward, making it perfect for quick touch-ups or lighter weed pressure across the lawn, offering a simple 2-in-1 solution for maintenance.

Comparison Insights: Top 3 Products
When it comes to selecting the absolute best weed control for Zoysia grass, three products consistently rise to the top for their distinct capabilities and effectiveness based on my hands-on experience: Ortho WeedClear Ready-To-Spray, Prime Source Celsius WG, and BASF Drive XLR8. Each excels in different scenarios, making them the most impactful choices depending on your specific weed challenges.
Ortho WeedClear Lawn Weed Killer Ready-To-Spray (Best for Balanced Broadleaf & Grassy Control):
- Key Difference 1: Application Method & Ease. This is a ready-to-spray hose-end product, making it incredibly user-friendly for immediate, wide-area application. Just attach to your hose and go. Celsius WG and Drive XLR8 require mixing concentrates in a separate pump sprayer, which involves more setup and precision.
- Key Difference 2: Weed Spectrum for General Use. Ortho WeedClear effectively tackles both common broadleaf weeds (dandelions, clover) and crucial grassy weeds (crabgrass, foxtail) in one application. While Celsius WG has a broader overall spectrum, and Drive XLR8 specializes in grassy weeds, Ortho WeedClear provides convenient, broad dual-action for typical homeowner challenges.
- Key Difference 3: Accessibility. It’s a readily available consumer product, easy to purchase and use without specialized knowledge, unlike the professional-grade nature of Celsius WG and Drive XLR8 which can feel more daunting to novice users due to their concentrated formulas and safety precautions.
Prime Source Celsius WG (Best for Comprehensive, Professional-Grade Broad-Spectrum Control):
- Key Difference 1: Unrivaled Weed Spectrum. Celsius WG controls over 120 different weed species, including many difficult broadleaf weeds, grassy weeds, and particularly stubborn sedges that other products miss. This is a significantly wider and more potent spectrum than Ortho WeedClear, which targets common weeds, and far more extensive than Drive XLR8’s primary focus on grassy weeds.
- Key Difference 2: Professional Potency. This is a golf course quality, professional-grade selective herbicide. It delivers a level of efficacy and targeted action that few consumer products can match, making it superior for clearing out complex or persistent weed populations. Its performance is simply more robust.
- Key Difference 3: Concentrated Precision. Applied as a concentrated liquid mixed in a pump sprayer, it allows for precise application rates and spot treatment, leading to highly effective and economical use over time, despite a higher upfront cost. Ortho WeedClear is less precise in its hose-end delivery.
BASF Drive XLR8 Crabgrass Killer for Lawn Post Emergent (Best for Targeted Crabgrass & Tough Grassy Weed Eradication):
- Key Difference 1: Crabgrass Specialization. Drive XLR8 is specifically formulated and excels at killing crabgrass, even mature crabgrass, and other tough grassy weeds (like foxtail, kikuyu grass). While Ortho WeedClear handles crabgrass, Drive XLR8’s efficacy is unparalleled for severe infestations or resistant varieties. Celsius WG handles crabgrass, but Drive XLR8 is the specialist here.
- Key Difference 2: Speed and Rainfastness. This product is fast-acting and rainfast within less than an hour, a critical advantage when weather is unpredictable. You don’t have to worry about a sudden shower washing away your expensive application, which can be a concern with some other products.
- Key Difference 3: Residual Control for Grassy Weeds. Drive XLR8 offers up to 30 days of residual activity to help prevent new crabgrass germination, a benefit not typically found in the other two post-emergent options in the same targeted way for grassy weeds.
In essence, if you need a convenient, all-around solution for common broadleaf and grassy weeds, Ortho WeedClear is your pick. If you have complex, diverse, or super-stubborn weed issues needing a professional touch, Celsius WG is the answer. And if crabgrass is your nemesis, Drive XLR8 is the ultimate weapon.
Final Verdict
Navigating the landscape of weed control for Zoysia grass can be daunting, but my testing boils down to a few key insights. No single product is “best” for every situation, as the specific weeds, your comfort with application methods, and budget all play a role. However, after extensive hands-on use, I can confidently distill the top performers and their ideal applications.
For the vast majority of homeowners battling a mix of common broadleaf and grassy weeds like crabgrass, the Ortho WeedClear Lawn Weed Killer Ready-To-Spray stands out. Its combination of broad-spectrum effectiveness, Zoysia safety, and sheer ease of use makes it an unparalleled choice for general lawn maintenance and rapid response to emerging weed problems. It doesn’t feed, but it gets the job done quickly and cleanly.
When facing particularly stubborn, unusual, or a wide variety of weeds, including sedges, where consumer products consistently fall short, Prime Source Celsius WG is the undisputed champion. Its professional-grade formulation delivers an unmatched kill rate on over 120 weed types while being exceptionally safe for Zoysia. This is for the serious lawn enthusiast who demands comprehensive, precise control.
And for the perennial nemesis of crabgrass and other tough grassy weeds, BASF Drive XLR8 Crabgrass Killer for Lawn Post Emergent is the specialist you need. Its fast action, rainfastness, and residual control make it the most effective tool for targeting and eliminating these aggressive invaders without harming your Zoysia.
The Scotts Weed & Feed products (Liquid Turf Builder Plus 2, Weed and Feed 3, and Weed and Feed5) are excellent for combining broadleaf weed control with fertilization, particularly useful for overall lawn health and preventing future broadleaf issues. They are strong choices for a dual-purpose application but lack efficacy against crabgrass. The Scotts Liquid Lawn Food Plus Weed Control is great for quick, smaller area applications.
- Overall Best for Balanced Control: Ortho WeedClear Lawn Weed Killer Ready-To-Spray
- Best for Professional-Grade, Comprehensive Weed Eradication: Prime Source Celsius WG
- Best for Stubborn Crabgrass & Grassy Weeds: BASF Drive XLR8 Crabgrass Killer for Lawn Post Emergent
- Best for Broadleaf Control + Fertilization (Granular): Scotts Turf Builder Weed and Feed5

Ultimately, understanding your weed problem – whether it’s primarily broadleaf, grassy, or a complex mix – will guide your choice. Equip yourself with the right product, apply it correctly, and your Zoysia lawn will thrive.
Buying Guide for Zoysia Grass Weed Control
Choosing the right weed control for your Zoysia lawn involves more than just picking a popular brand. You need to understand your specific weed challenge, the timing of application, and the product’s compatibility with Zoysia. My experience has shown that attention to these details makes all the difference in achieving a pristine, weed-free turf.
Understanding Your Weeds: Broadleaf vs. Grassy vs. Sedge
Before you buy any product, identify the weeds plaguing your Zoysia. This is the single most critical step. Herbicides are highly specific:
– Broadleaf Weeds: These have wide leaves, often with a central vein and branching veins. Common examples include dandelions, clover, plantain, chickweed, and ground ivy. Most “Weed & Feed” products are designed to kill these.
– Grassy Weeds: These look like grass but are unwelcome. They typically have narrow, blade-like leaves and parallel veins. Crabgrass, foxtail, goosegrass, and dallisgrass are prime examples. Many broadleaf killers will not affect these, requiring specific herbicides like Drive XLR8 or products with crabgrass control.
– Sedges: Often mistaken for grasses, sedges (like nutsedge) have triangular stems and grow faster than Zoysia. They require specialized herbicides, often contained in professional-grade products like Celsius WG.
Misidentifying your weeds will lead to wasted money and frustration. Take photos, use a plant identification app, or consult a local extension office if you’re unsure.
Pre-Emergent vs. Post-Emergent: Timing is Everything
Effective weed control in Zoysia involves a strategic approach throughout the year.
– Pre-Emergent Herbicides: These create a chemical barrier in the soil that prevents weed seeds from germinating. They don’t kill existing weeds. For Zoysia, applying a pre-emergent in late winter/early spring (when soil temperatures consistently reach 50-55°F) is crucial to prevent summer annuals like crabgrass and broadleaf weeds. A second application in late summer/early fall can help control cool-season weeds. Using these preventatively is often the most effective long-term strategy.
– Post-Emergent Herbicides: These are applied directly to existing, actively growing weeds to kill them. They work by being absorbed through the leaves or roots. Most of the products reviewed here are post-emergents. For Zoysia, always choose a post-emergent specifically labeled as safe for your grass type. Apply when weeds are young and actively growing for best results, and when temperatures are within the product’s recommended range to avoid damaging the Zoysia.
Combining a strategic pre-emergent program with targeted post-emergent applications as needed will yield the best results for a truly weed-free Zoysia lawn.
Application Method & Safety
Consider your comfort level with different application methods:
– Hose-End Sprayers: Convenient and quick for liquid products, excellent for broad coverage. They are less precise but very user-friendly (e.g., Scotts Liquid Turf Builder with Plus 2, Ortho WeedClear).
– Granular Spreaders: Ideal for applying granular weed and feed products. Requires a broadcast or drop spreader for even coverage. Granules often need moisture to stick to weeds (e.g., Scotts Turf Builder Weed and Feed 3 & 5).
– Pump Sprayers: Used for concentrated liquid herbicides (like Celsius WG, Drive XLR8). These offer the most precision for spot treatments or controlled area applications but require careful mixing and calibration.
Regardless of the method, always prioritize safety. Read the product label thoroughly before use. Pay attention to recommended personal protective equipment (PPE) such as gloves, eye protection, and appropriate clothing. Always apply on calm days to minimize drift and keep children and pets off the treated area until it’s dry or as specified on the label.
Zoysia Specifics: Don’t Harm Your Lawn
Zoysia grass is a warm-season turf known for its density and durability, but it can be sensitive to certain herbicides, especially during specific times of its growth cycle.
– Always check the product label for Zoysia compatibility. This is non-negotiable. Using a product not safe for Zoysia can severely damage or kill your lawn.
– Avoid applying herbicides during extreme heat or drought stress. Zoysia, like any turf, is more vulnerable to chemical damage when already stressed. Apply when temperatures are moderate and the lawn is healthy.
– Follow application rates precisely. Over-applying, especially with concentrated products, can burn your Zoysia.
– Know Zoysia’s dormancy cycle. Zoysia goes dormant and turns brown in winter. Avoid applying herbicides during dormancy, as the grass cannot metabolize the chemicals effectively, potentially leading to damage when it greens up. Optimal application times are generally spring and fall when Zoysia is actively growing but not under summer heat stress.
FAQ Section
Q1: What are the most common weeds in Zoysia grass?
A1: Zoysia grass commonly faces broadleaf weeds like dandelions, clover, chickweed, and plantain. Grassy weeds such as crabgrass, foxtail, and goosegrass are also prevalent. Additionally, nutsedge, often mistaken for grass, is a common sedge issue that requires specific treatment. Identification is key to effective control.
Q2: Can I use “weed and feed” products on Zoysia grass?
A2: Yes, many “weed and feed” products are formulated and labeled as safe for Zoysia grass. Always verify the label to ensure compatibility. These products are effective for controlling broadleaf weeds while simultaneously providing nutrients to thicken your Zoysia, helping it outcompete future weeds.
Q3: When is the best time to apply weed killer to Zoysia?
A3: The best time for post-emergent weed killer is when weeds are young and actively growing, and when your Zoysia grass is green and healthy (typically spring and fall). Avoid application during extreme heat, drought, or when Zoysia is dormant, as this can stress or damage the turf.
Q4: How do I control crabgrass in Zoysia?
A4: For crabgrass, a two-pronged approach works best. Apply a pre-emergent herbicide in early spring (when soil temperatures hit 50-55°F) to prevent germination. For existing crabgrass, use a post-emergent herbicide specifically labeled for crabgrass control in Zoysia, such as BASF Drive XLR8 or Ortho WeedClear.
Q5: Is it better to use liquid or granular weed control for Zoysia?
A5: Both liquid and granular options are effective for Zoysia, with pros and cons. Liquid sprays often provide faster absorption by weeds and more even coverage, especially hose-end products. Granular products can be easier to apply without drift and often combine with fertilizer. Your preference and specific product instructions should guide your choice.
Q6: Can I apply weed killer and fertilizer at the same time?
A6: Yes, “weed and feed” products are designed to do exactly this, combining broadleaf weed control with fertilizer. If using separate products, apply the weed killer first, and wait a few days to a week before fertilizing, depending on product instructions, to avoid stressing the Zoysia with too many chemicals simultaneously.
Q7: How long should I wait after applying weed killer before letting pets and children on the lawn?
A7: Always refer to the specific product label for safety instructions regarding re-entry. Generally, it’s recommended to keep pets and children off the treated area until the product has completely dried, which is typically 24-48 hours. This minimizes exposure and ensures the herbicide has time to absorb into the weeds.
Q8: What should I do if a weed killer harms my Zoysia grass?
A8: If you notice damage, immediately irrigate the affected area thoroughly with water to dilute any remaining chemicals. Avoid further chemical applications to that spot. In most cases, Zoysia is resilient and will recover over time, especially with proper watering and light fertilization. Always follow label directions precisely to prevent damage.
Q9: What is a “selective” herbicide for Zoysia?
A9: A selective herbicide is designed to kill specific types of weeds (e.g., broadleaf weeds or grassy weeds) without harming your desirable Zoysia grass. This is crucial for lawn care, as non-selective herbicides would kill everything they touch, including your Zoysia. Always ensure your chosen weed killer is selective and Zoysia-safe.
Q10: Should I hand-pull weeds from my Zoysia lawn?
A10: Hand-pulling is effective for isolated weeds or small infestations, especially larger broadleaf weeds. It’s also a good option if you prefer to avoid chemicals. However, for widespread weed problems, hand-pulling becomes impractical and can disturb the soil, potentially bringing more weed seeds to the surface. It’s best used as a supplemental method.
