More Details on Our Top Picks
Fertilome Crabgrass Preventer + Lawn Food 20-0-3, 16 lbs
This product stands out for its combination of fertilization and pre-emergent control, making it ideal for homeowners seeking a simplified lawn care routine. Unlike Scotts Turf Builder Triple Action, which also kills existing weeds, Fertilome focuses on prevention alongside boosting lawn resilience. Its 20-0-3 NPK ratio promotes healthy growth, while its ability to be applied up to 4 weeks later than other products offers flexibility. However, it does not control existing crabgrass, so timing is crucial. This pick suits those who want a dual-purpose product without extra steps, but it requires careful label consultation to match regional grass types.
Pros:- Combines fertilization and crabgrass prevention in one application
- Controls other annual grasses and broadleaf weeds
- Nitrogen and potassium promote season-long lawn resilience
Cons:- Application rate varies by region and grass type, requiring careful label reading
- Does not kill existing crabgrass, so timing must be precise
Best for: Homeowners who want an easy-to-apply, dual-function lawn product that emphasizes early season prevention and lawn health.
Not ideal for: Gardeners with existing crabgrass infestations needing immediate removal or control of mature weeds.
- Brand:Fertilome
- Model:11907
- NPK Ratio:20-0-3
- Weight:16 lbs
- Type:Lawn fertilizer + crabgrass preventer
Our verdict“This product is best suited for users seeking a preventive solution that also supports lawn health, with the understanding it won’t address mature weeds.”
GreenView Premium Formula Spring Lawn Fertilizer, Crabgrass Preventer 34 lb
This option makes the most sense for homeowners with sizable lawns needing extended crabgrass prevention paired with sustained fertilization. Compared with Scotts Turf Builder Triple Action, which offers weed control, GreenView emphasizes long-lasting feeding for up to 6 months, ideal if you prefer fewer applications. Its pre-emergent herbicide, Dimension, effectively prevents crabgrass and common weeds, but it is restricted to spring use, limiting year-round protection. Its large coverage area—up to 10,000 sq. ft.—adds to its value, though careful application is essential to avoid overuse or damage to sensitive plants. This choice suits those prioritizing long-term lawn resilience and broad weed prevention.
Pros:- Provides up to 6 months of fertilization
- Prevents crabgrass and controls 40 common weeds
- Large coverage area offers value for big lawns
Cons:- Requires precise application to avoid overuse
- Herbicide may not be suitable for all lawn types or areas
Best for: Lawn owners with large properties wanting a one-pass, long-duration prevention and feeding solution during spring.
Not ideal for: Users seeking year-round weed control or those with small or ornamental lawns where herbicide safety is a concern.
- Weight:34 lb
- Coverage:10,000 sq. ft.
- Pre-emergent Herbicide:Dimension
- Duration of Feeding:up to 6 months
Our verdict“This product is ideal for large lawn owners who want long-lasting prevention combined with sustained feeding, but it’s less suited for spot treatments or year-round control.”
Scotts Halts Crabgrass & Grassy Weed Preventer, 10.06 lbs.
Compared with products like Scotts Turf Builder Triple Action, Scotts Halts excels in its reliability for spring and fall applications, creating a barrier against crabgrass and other weeds without depending on weather conditions. Its weather-resistant performance means it won’t be affected by rain or snow, making timing less critical. Covering 5,000 sq. ft., it’s suitable for medium-sized lawns. However, it doesn’t control existing weeds or mature crabgrass, so homeowners with ongoing problems will need supplementary treatments. Its exclusion of Dichondra and Bentgrass lawns is a minor limitation, but overall, it’s a straightforward, dependable preventative for seasonal use.
Pros:- Effective pre-emergent weed prevention for crabgrass and other weeds
- Weather-resistant, unaffected by rain or snow
- Covers a large area per bag
Cons:- Does not control existing or mature crabgrass
- Requires reapplication every 8 weeks for weeds like goosegrass
Best for: Homeowners seeking a reliable, seasonal pre-emergent for spring and fall, especially in regions with unpredictable weather.
Not ideal for: Those needing to treat existing crabgrass or weeds or seeking year-round weed management.
- Brand:Scotts
- Weight:10.06 lbs
- Coverage:5,000 sq. ft.
- Application:Spring and fall
Our verdict“This product suits users focused on seasonal prevention in variable climates, but it won’t address existing weed issues.</p>”
Scotts Turf Builder Triple Action Lawn Fertilizer and Weed Control, 33.94 lbs.
This pick makes the most sense for homeowners who want a comprehensive lawn treatment that combines fertilization, weed control, and crabgrass prevention. Compared with Scotts Turf Builder Triple Action1, which offers similar 3-in-1 benefits, this option provides up to 4 months of crabgrass prevention, making it ideal for those seeking longer protection. Its ease of application—especially with Scotts spreaders—and its ability to handle various weed types make it versatile. However, it requires watering after application and isn’t suitable for newly seeded lawns. Its multi-functionality comes with the tradeoff of needing careful application to avoid overfeeding or affecting non-target plants.
Pros:- Kills and prevents multiple types of weeds
- Provides up to 4 months of crabgrass prevention
- Suitable for various grass types
Cons:- Requires watering after application for best results
- Does not control existing weeds or crabgrass
Best for: Lawn owners wanting a straightforward, all-in-one product that prevents crabgrass and controls weeds for several months with minimal effort.
Not ideal for: People with recently seeded lawns or those needing control of mature weeds or existing crabgrass.
- Weight:33.94 lbs
- Coverage:12,000 sq. ft.
- Application:Apply to wet lawn, water after 24 hours
Our verdict“This product is best for users seeking an easy, comprehensive lawn treatment with long-lasting weed prevention, provided they follow application instructions carefully.”
Scotts Turf Builder Triple Action1 Lawn Fertilizer, 11.31 lb.
Compared with larger options like Scotts Turf Builder Triple Action, this smaller bag suits homeowners with limited lawn space or those who prefer targeted treatments. It offers a 3-in-1 formula that feeds, kills weeds, and prevents crabgrass for up to 4 months, covering around 4,000 sq. ft. per bag. Its specific application steps—wet lawn and watering afterward—are similar to larger Scotts products but scaled down. While it’s effective for small to medium lawns, it won’t be cost-effective for bigger properties and doesn’t kill existing weeds. Its compact size makes it easier to handle for DIYers with limited storage but less economical for large areas.
Pros:- 3-in-1 formula with fertilization, weed control, and crabgrass prevention
- Covers up to 4,000 sq. ft. per bag, ideal for small lawns
- Easy to handle and store due to its size
Cons:- Does not kill existing crabgrass or weeds
- Requires precise application and watering, similar to larger Scotts products
Best for: Homeowners with small or medium-sized lawns seeking a manageable, multi-purpose weed and crabgrass preventer.
Not ideal for: Owners of large lawns or those needing to treat existing weeds or crabgrass already present in the yard.
Our verdict“This product is perfect for small lawn owners who want a simple, effective prevention and feeding solution without the need for large quantities or complex application routines.”
Bonide Dura Turf Crabgrass and Weed Preventer, 9.5 lb
This ready-to-use formula stands out for its ability to prevent over twenty types of weeds, including crabgrass, with a coverage of up to 5,000 square feet. Compared to the Scotts WeedEx Prevent, which also offers broad weed control, Bonide Dura Turf provides a longer-lasting effect—up to four months—making it ideal for homeowners seeking minimal reapplication. However, it does not contain fertilizer, so you’ll need to fertilize separately. Its ease of application suits those with established lawns who want reliable, season-long weed prevention without complex mixing. The main tradeoff is the restriction against use on edible plants, which limits its use around vegetable gardens.
Pros:- Effective against a wide variety of weeds including crabgrass
- Provides control for up to four months
- Ready to use with simple application
Cons:- Not suitable for use on edible plants
- Requires careful application to avoid non-target areas
Best for: Homeowners with ornamental gardens and lawns seeking effective, long-term weed prevention in spring.
Not ideal for: Gardeners growing edible plants, since it is not suitable for use on fruit or vegetable crops.
- Weight:9.5 lb
- Coverage:Up to 5,000 sq ft
- Application:Spring
- Use:Lawns and ornamental gardens
- Contains fertilizer:No
Our verdict“This pick makes the most sense for homeowners seeking broad, long-lasting weed prevention without the need for fertilizers.”
Scotts WeedEx Prevent with Halts Pre-Emergent Weed Preventer, 10.06 lbs
Scotts WeedEx Prevent excels at stopping a broad spectrum of weeds—including crabgrass, spurge, and Poa annua—before they emerge, with a coverage of 5,000 sq. ft. It’s compatible with all grass types except Dichondra and Bentgrass, and its performance remains unaffected by rain, snow, or freezing conditions, making it a reliable choice for unpredictable spring or fall applications. Compared to the Andersons Barricade, which is more focused on professional-grade control, Scotts offers user-friendly coverage with less fuss. Its limitation lies in only controlling weeds at the seed stage, so it won’t eliminate mature weeds already growing. It also doesn’t prevent moss in California, a potential downside for some regions.
Pros:- Prevents a wide range of weeds before germination
- Unaffected by weather after application
- Safe for use on most grass types
Cons:- Does not kill existing weeds
- Not suitable for Dichondra or Bentgrass lawns
- Moss prevention not available in California
Best for: Homeowners needing dependable, rain-resistant pre-emergent weed control across varied weather conditions.
Not ideal for: Lawn owners with Dichondra or Bentgrass, as it’s not compatible with those grass types.
- Weight:10.06 lbs
- Coverage:5,000 sq. ft
- Application Timing:Early spring or fall
- Compatible Grass Types:Most, except Dichondra and Bentgrass
- Active Concerns:Crabgrass, foxtail, spurge, moss, Poa annua, henbit, chickweed
Our verdict“Ideal for those wanting a weather-proof, broad-spectrum pre-emergent that works regardless of rain or cold.”
Jonathan Green & Sons Crabgrass Preventer, 5,000 sq ft
This straightforward crabgrass preventer offers season-long control, ideal for homeowners who want a no-fuss, effective solution. It covers 5,000 square feet and requires no assembly, making it accessible for those new to lawn care. Compared with the Andersons Barricade, which is more professional-grade and suitable for multiple weed types, Jonathan Green focuses solely on crabgrass, providing a targeted approach. The main limitation is its focus on crabgrass only, so if you’re dealing with broadleaf weeds or other grasses, this might not be enough. It’s best suited for those with smaller lawns or specific crabgrass issues, but it’s less versatile for comprehensive weed management.
Pros:- Provides season-long crabgrass control
- No assembly required
- Easy to apply
Cons:- Limited to crabgrass prevention only
- Coverage may be insufficient for very large properties
Best for: Homeowners seeking a simple, effective crabgrass preventer for lawns primarily affected by crabgrass.
Not ideal for: Lawn owners needing broad-spectrum weed control or with large properties, due to its limited coverage and scope.
- Coverage:5,000 sq ft
- Application:Crabgrass prevention
- Assembly:No
Our verdict“A solid choice for homeowners focused solely on preventing crabgrass without extra fuss.”
The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control – Covers up to 5,800 sq ft (18 lb)
This professional-grade product stands out for its rapid-dissolving granules, which activate quickly upon watering, offering effective soil treatment for early spring and fall. It covers nearly 6,000 sq. ft., making it suitable for larger lawns or multiple treatment zones. Compared with the Scotts WeedEx, Barricade is more suited to those seeking a stronger, possibly more durable control, thanks to its pro-grade formulation. Its main limitation is that it only prevents weeds in the pre-emergent stage, meaning it won’t eliminate existing weeds—so it’s best for pre-season application. Also, it requires watering for activation, adding a step that some homeowners might find inconvenient.
Pros:- Effective pre-emergent weed prevention
- Rapidly dissolving granules for easy application
- Suitable for early spring and fall treatments
Cons:- Does not kill existing weeds
- Requires watering for activation
Best for: Lawn care professionals or dedicated homeowners who want a powerful, fast-acting pre-emergent for large areas and multiple seasons.
Not ideal for: Homeowners with small lawns or those looking to control existing weeds, since it focuses on prevention only.
- Coverage Area:5,800 sq ft
- Weight:18 lb
- Active Ingredient:Prodiamine 0.48%
- Made in:USA
- Application Seasons:Spring and Fall
Our verdict“Best suited for those with large lawns or professional-grade needs focused on pre-season weed prevention.”
The Andersons Premium Crabgrass Preventer Plus Fertilizer 26-0-6 with Dimension, 17 lb
This product combines crabgrass prevention with lawn feeding, offering up to four months of weed control alongside a balanced fertilizer. It’s ideal for homeowners who want to combine weed prevention with a spring green-up, thanks to its mix of quick- and slow-release nitrogen. Compared with the Barricade, which focuses solely on weed prevention, this option adds the benefit of feeding. However, it’s limited to lawns up to 6,000 sq. ft. and is not safe for dichondra or bentgrass, which might restrict its use around certain landscape types. Its dual function makes it especially appealing for those seeking convenience, but for those with larger properties or specific turf types, it may fall short.
Pros:- Provides up to 4 months of weed prevention
- Includes quick- and slow-release nitrogen for spring green-up
- Covers up to 6,000 sq ft
Cons:- Limited to lawns under 6,000 sq ft
- Not suitable for certain turf types like dichondra or bentgrass
Best for: Homeowners looking for a combined lawn fertilizer and weed prevention solution for up to 6,000 sq. ft.
Not ideal for: Lawn owners with dichondra or bentgrass, as it’s not safe for these turf types.
- Coverage:6,000 sq ft
- Weight:17 lb
- Active Ingredient:Dimension
- Fertilizer Ratio:26-0-6
- Application:Lawn fertilizer and weed preventer
Our verdict“Best suited for homeowners wanting a combined feed and weed prevention for mid-sized lawns.”
Lebanon Prodiamine 0.58G Crabgrass Preventer 40 lb. Bag
This granular pre-emergent offers impressive coverage for extensive lawns and professional landscapes, making it ideal for large properties needing reliable crabgrass prevention. Compared with GreenView Premium, which is better suited for homeowners with smaller lawns, Lebanon Prodiamine delivers a much larger area coverage (20,000 sq. ft. vs. 10,000 sq. ft.), but it requires careful timing and professional application for best results. Its granular form ensures even distribution across turf, trees, and flower beds, reducing weed germination effectively. The main tradeoff is its limited availability in certain states and the need for precise application timing, which might challenge casual users. Overall, this product stands out for those managing large lawns or commercial landscapes demanding robust, professional-grade weed prevention.
Pros:- Huge coverage area of 20,000 sq. ft. per bag
- Effective against crabgrass and grassy weeds
- Suitable for turf, trees, shrubs, and flowers
Cons:- Limited availability in some states (e.g., CA, FL, NY)
- Requires precise timing and professional application
Best for: Landscapers, professional lawn care services, or homeowners with large, mixed landscapes
Not ideal for: Small residential lawns or casual gardeners who prefer ready-to-use, easy-apply products
- Brand:LebanonTurf
- UPC:088685402838
- Coverage:20,000 sq. ft.
- Weight:40 lbs
- Application:Pre-emergent grassy weeds and crabgrass
- Model Number:2440573
Our verdict“This product is ideal for large-scale or professional applications where coverage and effectiveness outweigh convenience.”
Preen Lawn Crabgrass Control 15 lb. Bag, Covers 5,000 sq. ft.
Preen Lawn Crabgrass Control strikes a balance between ease of use and effective weed prevention, making it well-suited for homeowners seeking season-long control. Unlike Lebanon Prodiamine, which is more suited to professionals or large properties, Preen is designed for smaller lawns and allows application after crabgrass emergence (up to 4 weeks), offering flexibility. Its ability to be used on a variety of grasses makes it versatile, but users must carefully time applications for maximum effectiveness and reapply if they want extended coverage. Its moderate coverage of 5,000 sq. ft. fits most residential lawns, though it may require reapplication for prolonged seasons. This product makes the most sense for homeowners who want reliable, season-long weed control without complex procedures.
Pros:- Provides up to 4 months of crabgrass prevention
- Effective on a wide variety of grass types
- Can be applied after crabgrass emergence for post-control
Cons:- Requires precise timing for best results
- May need reapplication for full season coverage
Best for: Homeowners with medium-sized lawns seeking flexible, long-lasting weed prevention
Not ideal for: Large properties or commercial landscapes that need extensive coverage or professional-grade solutions
- Brand:Preen
- Weight:15 lbs
- Coverage:5,000 sq. ft.
- Application Timing:Up to 4 weeks after emergence
- Suitable for:Multiple grass types
- Model Number:2464064
Our verdict“This product offers a practical, flexible option for homeowners wanting season-long crabgrass control with moderate effort.”
GreenView Premium Formula Spring Weed and Feed & Crabgrass Preventer, 36 lb.
GreenView’s combination of fertilizer and pre-emergent crabgrass preventer makes it ideal for homeowners who want to feed and protect their lawns simultaneously. Unlike the dedicated pre-emergents like Lebanon Prodiamine or Preen, which focus solely on weed prevention, this product offers a comprehensive solution — feeding the turf for up to 6 months while preventing crabgrass for about 4 months. Its slow-release nitrogen ensures consistent turf health, but it’s only suitable for established lawns, not new seedings. The granular formulation and coverage of up to 10,000 sq. ft. make it convenient for routine maintenance, though timing sensitivity means it must be applied at the right moment for crabgrass prevention to be effective. This pick is best for homeowners seeking a dual-purpose product that simplifies lawn care.
Pros:- Combines fertilization, weed killing, and crabgrass prevention
- Covers up to 10,000 sq. ft. with one application
- Provides up to 6 months of feeding
Cons:- Timing-sensitive for crabgrass prevention
- Not suitable for new seedings or delicate turf
Best for: Homeowners with established lawns who want to fertilize and prevent weeds simultaneously
Not ideal for: New seedings or lawns with delicate or newly planted turf, due to timing sensitivity
- Bag Weight:36 lbs
- Coverage:Up to 10,000 sq. ft.
- NPK Analysis:24-0-6
- Feeding Duration:Up to 6 months
- Crabgrass Prevention:Up to 120 days
- Formulation:Granular, slow-release
Our verdict“This product simplifies lawn care by combining feeding and crabgrass prevention, ideal for established lawns needing comprehensive treatment.”
How We Picked
I evaluated each product based on its weed prevention effectiveness, ease of use, coverage area, and price. Products that deliver consistent results and are simple to apply ranked higher, especially those with proven active ingredients like Prodiamine or Dithiopyr. I also considered build quality, customer reviews, and whether the product offers additional benefits like lawn fertilization. The ranking reflects the best balance of value, performance, and versatility for different lawn care needs, with top picks excelling across these factors while tradeoffs highlight cost or convenience considerations.Factors to Consider When Choosing Best Crabgrass Preventers
Choosing the right crabgrass preventer involves understanding several key factors that influence lawn health and weed control. Beyond just price, consider how the product fits your lawn size, your timing schedule, and the specific weeds you want to prevent. Proper application techniques and active ingredient longevity can make a big difference in effectiveness. Being aware of common mistakes, like applying at the wrong time or over-using chemicals, can help you avoid costly errors. This guide covers the essential considerations to help you select a crabgrass preventer that aligns with your lawn care goals.Active Ingredients and Effectiveness
Look for products containing proven pre-emergent chemicals such as Prodiamine, Dithiopyr, or Pendimethalin. These ingredients provide long-lasting control and are more reliable than generic weed preventers. Choosing a product with the appropriate active ingredient depends on your local climate and the weeds prevalent in your area. Be cautious of products with weaker formulas that may require multiple applications or less effective results, especially in high-pressure weed zones.
Coverage Area and Bag Size
Matching the product’s coverage to your lawn size prevents waste and ensures complete control. Larger bags typically offer better value per square foot but require more storage space. Smaller containers are convenient for small lawns but can become costly over time. Assess your lawn size carefully and pick a product that provides ample coverage without excess leftovers, which could lead to unnecessary expenses.
Timing and Application Method
Applying pre-emergent crabgrass preventers at the right time—usually early spring before soil warms—is critical for success. Some products are easier to apply with a spreader, while others come in ready-to-use formulations. Mistimed applications can render your efforts ineffective or harm your existing grass. Read instructions carefully to align your treatment schedule with your local climate and lawn growth cycle.
Additional Lawn Benefits
Some products include fertilizer components, offering dual benefits of weed prevention and lawn nourishment. This can save time and money, especially if you prefer a single-step treatment. However, these multi-benefit products tend to be pricier and might not suit lawns with specific nutritional needs. Consider your lawn’s soil health and whether a separate fertilization plan might be more appropriate.
Cost vs. Performance Tradeoffs
Higher-priced products often provide longer-lasting control and better coverage, but there are effective budget options available. Cheaper products may require more frequent reapplications or may not perform as well under high weed pressure. Balance your budget with your desired lawn quality—investing a bit more upfront can reduce ongoing costs and effort over the season.
Frequently Asked Questions
When is the best time to apply crabgrass preventer?
The optimal window for applying crabgrass preventers is early spring before soil temperatures reach 55°F. Applying too early may reduce effectiveness, while late applications can allow weeds to establish. Monitoring local weather and soil temperature is key—aim for just before crabgrass seeds typically germinate in your area.
Can I apply crabgrass preventer and fertilizer at the same time?
Many products combine pre-emergent chemicals with fertilizer, simplifying your lawn care routine. If using separate products, it’s best to apply the pre-emergent first, then wait a few days before fertilizing. This sequencing prevents chemical interference and ensures both treatments work effectively without overwhelming your lawn.
Will crabgrass preventer harm my existing grass?
Most pre-emergent products are safe for established lawns when applied correctly and at the right time. However, over-application or applying during sensitive growth periods can cause stress or damage. Always follow the manufacturer’s instructions and avoid applying during drought stress or extreme heat to protect your turf.
How long does crabgrass preventer typically last?
The longevity of crabgrass preventers varies, but most provide protection for about 8 to 12 weeks. Some advanced formulas with active ingredients like Prodiamine can last longer with a single application, reducing the need for reapplication. Check product labels for specific coverage durations to align with your lawn’s seasonal needs.
Is it necessary to water after applying pre-emergent?
Yes, watering after application helps to activate the chemical and ensure it penetrates the soil effectively. Typically, a light watering of about ¼ inch of water is recommended within 24 hours of application. This step enhances the product’s ability to form a barrier against crabgrass seeds and increases its overall effectiveness.
Conclusion
The best overall pick, Fertilome Crabgrass Preventer + Lawn Food, offers reliable control plus lawn nourishment, making it ideal for most homeowners. For budget-conscious buyers, Preen Lawn Crabgrass Control provides solid coverage at a lower price without sacrificing too much performance. If you want a premium, long-lasting solution with added fertilizer benefits, the Andersons Premium Crabgrass Preventer Plus Fertilizer is worth the investment. Beginners should consider easy-to-apply formulas like Scotts Halts or Scotts Turf Builder Triple Action, which combine weed control with user-friendly features. For specific needs, such as large coverage or organic options, select a product that aligns with those priorities to keep your lawn healthy and crabgrass-free throughout the season.
