More Details on Our Top Picks
The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control – Covers up to 5,800 sq ft (18 lb)
This product excels in preventing a broad spectrum of weeds like crabgrass and poa annua, thanks to prodiamine, making it ideal for proactive lawn maintenance. Compared to larger coverage options like Yard Mastery’s 45 lb bag, it offers a more manageable size for smaller lawns but still delivers professional-grade results. Its quick-dissolving granules ensure rapid soil absorption, which is key for effective prevention when applied early in the season. However, it doesn’t tackle existing weeds, so it’s less suitable for lawns with established weed problems. Its limited to pre-emergent use only, so it needs to be paired with other products for full weed control.
Pros:- Effective prevention of both grassy and broadleaf weeds
- Granules dissolve quickly for fast soil absorption
- Covers up to 5,800 sq ft, ideal for small to medium lawns
Cons:- Does not eliminate established weeds
- Limited to pre-emergent use only
- Requires application early in the season for best results
Best for: Homeowners seeking reliable weed prevention with easy application and manageable size.
Not ideal for: Gardeners with existing weed issues who need a product with post-emergent action or broader weed control spectrum.
- Coverage:5,800 sq ft
- Weight:18 lb
- Active Ingredient:Prodiamine 0.48%
- Application:Pre-emergent weed control
- Technology:DG Technology (dispersible granules)
- Made in:USA
Our verdict“This product suits proactive homeowners who want professional-grade weed prevention without handling larger quantities or post-emergent needs.”
5-0-30 Pre-Emergent Weed Control & Lawn Fertilizer, 15 lb
This product stands out for its dual action: preventing over 30 weed species while nourishing the lawn with balanced nutrients and iron, resulting in a lush, stress-resistant turf. Compared to Yard Mastery’s 45 lb bag, it offers a more convenient size for smaller lawns and easier application, especially with a broadcast spreader. Its requirement to water within 24 hours after application emphasizes the need for timely, attentive use, unlike products like Lesco 19-0-6 that focus more on slow-release fertilization. While it excels in early spring and fall, it’s less suitable for year-round weed prevention or lawns needing post-emergent weed control.
Pros:- Prevents over 30 weed types including crabgrass
- Strengthens turf against environmental stressors
- Easy to apply with broadcast spreader and quick watering
Cons:- Requires watering within 24 hours after application
- Limited use outside early spring and fall
- Cannot address existing weeds
Best for: Homeowners wanting a combined fertilizer and weed preventer for seasonal, proactive lawn care.
Not ideal for: Lawn care enthusiasts seeking a product with broad-spectrum, year-round weed control or post-emergent options.
- Weight:15 lb
- Coverage:up to 5,000 sq ft
- Application:Broadcast, water-in within 24 hours
- Type:Pre-emergent weed control and fertilizer
Our verdict“This pick makes the most sense for homeowners seeking an easy, seasonal solution that combines weed prevention with turf nourishment.”
Yard Mastery 0-0-7 Dimension Pre-Emergent Herbicide – 45 lb Bag
This product provides extensive coverage up to 15,000 sq ft, making it suitable for large lawns or multiple smaller areas. Its combination of dithiopyr as a pre-emergent herbicide and a 0-0-7 fertilizer blend supports early season weed prevention while promoting turf health. Compared to Lesco 19-0-6, it offers a similar fertilizer ratio but at a more affordable price point and larger coverage. Its granular form requires precise spreading and proper timing, or else its effectiveness diminishes. It’s limited to pre-emergent use, so it’s best paired with post-emergent treatments for full weed management.
Pros:- Large coverage area up to 15,000 sq ft
- Contains fertilizer for turf health
- Effective against crabgrass and broadleaf weeds when timed correctly
Cons:- Requires accurate timing for maximum effectiveness
- Granular application may need careful spreading
- Limited to pre-emergent use only
Best for: Lawn owners with large areas seeking cost-effective weed prevention combined with turf health benefits.
Not ideal for: Homeowners with small lawns or those needing post-emergent weed control and broader weed spectrum management.
- Weight:45 lb
- Coverage:up to 15,000 sq ft
- Active Ingredient:Dithiopyr
- Application:Pre-emergent weed control
Our verdict“This product is best suited for large lawns where budget-friendly, large-area weed prevention is a priority.”
Lesco 19-0-6 Dimension Pre-Emergent Fertilizer – 50 lb
Lesco’s formulation combines pre-emergent weed control with a balanced NPK ratio of 19-0-6, making it suitable for comprehensive lawn health and weed prevention. Compared with Yard Mastery, it offers a more traditional slow-release fertilization, which can be advantageous for sustained growth but may require longer to show visible turf improvements. Its coating, PolyPlus OPTI45, ensures slow release, reducing nutrient runoff, but this also means less immediate nutrient availability. Given its non-return policy, careful application is necessary to avoid over-application or runoff, especially in rain-prone areas.
Pros:- Effective pre-emergent weed control with Dimension
- Provides sustained, balanced fertilization
- Slow-release nitrogen minimizes nutrient runoff
Cons:- Non-returnable, so requires careful application
- Potential nutrient runoff if misapplied or in heavy rain
- Less immediate turf response compared to quick-release fertilizers
Best for: Lawn enthusiasts seeking a reliable, balanced pre-emergent and fertilizer combo for consistent turf health.
Not ideal for: Homeowners who prefer quick green-up or need post-emergent weed control solutions.
- Herbicide Content:0.15% Dimension
- NPK Ratio:19-0-6
- Weight:50 lb
- Coating:PolyPlus OPTI45
Our verdict“This product fits well for those prioritizing steady turf development and weed prevention over rapid results.”
Quali-Pro Prodiamine Pre-Emergent Herbicide, 5 lbs, Yellow Granules
This product offers strong, season-long weed prevention with a high concentration of prodiamine, making it suitable for lawns, landscapes, and golf courses. Compared to The Andersons Barricade, it provides a more concentrated active ingredient for longer-lasting control, especially when applied in spring and fall. Its yellow granules are easy to identify during spreading, but proper timing remains essential for effectiveness. While it excels at preventing weeds, it does not provide any fertilization benefits, so it must be used alongside other products to support turf health.
Pros:- Effective for multiple seasons with proper timing
- High concentration of prodiamine for long-lasting control
- Can be mixed with fertilizers and iron solutions
Cons:- Needs precise timing for maximum effectiveness
- Limited to pre-emergent weed control only
- Requires careful application to avoid missing weed prevention windows
Best for: Landscapers and serious lawn owners who need reliable, multi-season weed control with flexible application timing.
Not ideal for: Homeowners seeking combined fertilization with weed prevention or those with small, ornamental gardens needing post-emergent control.
- Active Ingredient:Prodiamine 65%
- Weight:5 lbs
- Application:Spring and fall
- Color:Yellow granules
Our verdict“This product is best suited for proactive land managers who need reliable, long-term weed prevention across various landscapes.”
Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food
This product stands out for combining effective crabgrass prevention with lawn fertilization that promotes quick green-up and strong root growth. Its ability to work in rain, snow, or freezing conditions makes it a top choice for those seeking reliable, season-long protection without seasonal timing worries. Compared with products like The Andersons Premium Crabgrass Preventer, it offers similar weed prevention but emphasizes rapid lawn feeding, making it ideal for early season care. The main tradeoff is the requirement to water within 2-3 days, which can be inconvenient in dry conditions. Overall, this pick makes the most sense for homeowners who need dependable, all-weather coverage and quick lawn improvement.
Pros:- Effective crabgrass prevention across diverse weather conditions
- Provides quick lawn green-up with integrated fertilization
- Works reliably in rain, snow, or freezing weather
Cons:- Requires watering within 2-3 days for optimal results
- May be less effective if watering guidelines are not followed
Best for: Homeowners seeking a reliable, all-season preemergent and fertilizer combo that works in various weather conditions
Not ideal for: Those who cannot water within a few days of application or prefer a product with longer soil residuals without watering requirements
- Coverage Area:5,000 sq. ft.
Our verdict“Best suited for homeowners who need dependable, weather-resistant lawn protection and quick greening, despite the watering requirement.”
Scotts Halts Crabgrass & Grassy Weed Preventer, 10.06 lbs
Compared with the Scotts Turf Builder, this product offers a broader application window by covering both spring and fall, making it ideal for seasonal weed control. Its weather-resistant performance allows effective weed prevention regardless of timing, but proper application timing is crucial for best results, and severe weed problems might require multiple applications. This flexibility makes it ideal for proactive homeowners who want to prevent weeds before they emerge. However, it may not be suitable for those looking for a single, quick-season solution, especially if weed issues are severe. This product is best for gardeners prioritizing broad, season-long weed prevention with flexible timing.
Pros:- Effective season-long prevention for multiple weeds
- Suitable for both spring and fall applications
- Weather-resistant performance ensures reliable results
Cons:- Requires proper timing for maximum effectiveness
- May need multiple applications for severe weed problems
Best for: Homeowners wanting effective, season-long weed prevention with flexible spring and fall application windows
Not ideal for: Gardeners with severe weed infestations that might require multiple treatments or those needing immediate, short-term control
- Weight:10.06 lbs
Our verdict“Ideal for proactive homeowners seeking flexible, long-term weed prevention across different seasons.”
This product excels by combining up to 4 months of crabgrass prevention with a balanced nutrient profile, making it suitable for most turf types. Its inclusion of both quick- and slow-release nitrogen ensures rapid green-up while supporting ongoing lawn health. Compared with the Veri-Green, which offers a longer 3-month control, this product provides longer-lasting protection suitable for homeowners wanting fewer applications. However, it isn’t safe for dichondra and bentgrass, and its regional restrictions limit availability. This pick is ideal for those seeking a comprehensive, long-term solution with fertilization benefits.
Pros:- Provides up to 4 months of crabgrass and weed prevention
- Includes both quick- and slow-release nitrogen for rapid and sustained green-up
- Suitable for most turf types
Cons:- Not safe for dichondra and bentgrass lawns
- Unavailable in certain states like NY, FL, CA, IN
Best for: Homeowners with established turf seeking long-lasting weed control plus ongoing lawn nourishment
Not ideal for: Gardeners with dichondra or bentgrass lawns or those in restricted states like NY, FL, or CA
- N-P-K:26-0-6
- Coverage:6,000 sq ft
- Weight:17 lb
- Active Ingredient:Dimension
Our verdict“Best for established lawns where long-lasting weed prevention and fertilization are priorities, and regional restrictions are manageable.”
Jonathan Green Veri-Green Crabgrass Preventer & Fertilizer – 15,000 Sq Ft
Compared with the Andersons product, Veri-Green emphasizes a broader coverage area, making it suitable for larger lawns up to 15,000 sq ft. Its nutrient analysis of 20-0-3 provides a gentle, season-long fertilization experience, ideal for spring applications before crabgrass germination. Its ease of application with standard spreaders simplifies use for homeowners managing large spaces. However, it cannot be used when seeding a new lawn and offers only up to 3 months of fertilization, slightly shorter than some competitors. This makes it well-suited for large, established lawns needing reliable, broad coverage with basic weed prevention and fertilization.
Pros:- Covers up to 15,000 sq ft, ideal for large lawns
- Provides up to 3 months of gradual fertilization
- Easy to apply with standard spreaders
Cons:- Cannot be used during lawn seeding
- Limited fertilization duration compared to some competitors
Best for: Homeowners with large lawns up to 15,000 sq ft seeking effective, easy-to-apply crabgrass prevention with moderate fertilization
Not ideal for: Those establishing a new lawn or requiring longer fertilization periods beyond 3 months
- Coverage:15,000 sq ft
- Weight:50 lbs
- Nutrient Analysis:20-0-3
Our verdict“Best for large, established lawns needing straightforward, large-area crabgrass prevention and moderate fertilization coverage.”
Prodiamine 65 WDG 5lbs Pre-emergent Grass & Broadleaf Weed Control
This product offers effective pre-emergent control specifically targeting crabgrass and broadleaf weeds, making it ideal for precise applications. Its formulation allows for accurate dosing and application when timing is critical, which distinguishes it from products like Scotts Turf Builder that focus on broader lawn feeding. The key tradeoff is that it requires proper timing and careful application; misuse can reduce its effectiveness or cause harm. It’s less suitable for casual users or those seeking a combined fertilizer component. This pick is best for experienced homeowners or landscapers aiming for targeted, high-precision weed prevention.
Pros:- Highly effective for targeted pre-emergent weed control
- Suitable for both crabgrass and broadleaf weeds
- Easy to apply with proper timing
Cons:- Requires careful timing for effectiveness
- Potentially harmful if misused or applied improperly
- No fertilizer component included
Best for: Experienced homeowners or landscapers needing precise control over crabgrass and broadleaf weeds with targeted application timing
Not ideal for: Beginners or homeowners looking for a combined fertilizer and weed preventer with easy, no-fuss application
- Weight:5 lbs
- Application:Pre-emergent weed control
- Target weeds:Crabgrass, broadleaf weeds
Our verdict“Ideal for experienced users seeking precise, effective weed prevention with strict timing requirements and no fertilization.”
Lesco 0-0-7 with 0.43% Stonewall Pre-Emergent, 50 lbs
This Lesco pre-emergent stands out for its impressive coverage area of 12,500 sq. ft, making it ideal for larger lawns or multiple landscape beds. Compared to smaller packages like the Yard Mastery 0-0-7, it offers a more economical solution for extensive areas without sacrificing weed prevention duration — up to 4 months. Its inclusion of potassium and iron not only helps prevent weeds but also supports turf health, a benefit not always found in basic pre-emergents. However, the product’s non-returnable nature means you need to be certain of your lawn’s needs before applying, and it’s strictly a weed barrier, offering no fertilizer component. This makes it better suited for homeowners prioritizing long-term weed control over fertilization. The large bag size is a plus for extensive coverage, but it might be too much for smaller yards or those with minimal weed issues.
Pros:- Prevents weeds for up to 4 months, reducing the need for frequent reapplication
- Large coverage area of 12,500 sq. ft offers great value for big lawns
- Enhanced with iron for turf health benefits
Cons:- Non-returnable and non-refundable, requiring confidence before purchase
- Limited to pre-emergent weed control only, no fertilizer included
Best for: Lawn care professionals or homeowners with large landscapes seeking long-lasting weed prevention and nutrient boosting in a single application.
Not ideal for: Small yard owners or those who prefer combined fertilization and weed control, since this product only prevents weeds and does not fertilize.
- Nutrient Ratio:0-0-7
- Active Ingredient:0.43% Stonewall Pre-Emergent
- Weight:50 lbs
- Coverage Area:12,500 sq. ft
- Includes:Potassium, Iron
Our verdict“This product is ideal for large-scale applications where long-term weed prevention and added turf support are priorities, but less suited for those wanting combined fertilization.”
Fertilome St. Augustine Weed & Feed 15-0-4, 25.6 lbs
This Fertilome Weed & Feed is tailored for St. Augustine, Centipede, and Zoysia lawns, making it a targeted choice for homeowners with these grass types. Unlike the Lesco product, which focuses solely on weed prevention, this combo offers both weed control and fertilization, providing a more complete lawn care solution—especially useful for early spring applications when growth starts. Its nitrogen-rich formulation (15-0-4) helps promote healthy, lush turf, but it’s not suitable for Bermudagrass or Northern grasses, which limits its versatility. The 25.6-lb bag covers about 5,000 sq. ft, fitting smaller to medium-sized lawns, yet the application instructions can be tricky if your area varies greatly in size, requiring careful measurement. It’s best for those seeking quick, combined weed and nutrient management in specific warm-season grasses, but not for those with different turf types or seeking a broad-spectrum product.
Pros:- Combines weed control and fertilization in one product for convenience
- Effective on specific warm-season grasses, improving lawn health quickly
- Covers a substantial 5,000 sq. ft for its size
Cons:- Not suitable for Bermuda or Northern grasses, limiting its use
- Application instructions require careful measurement, especially on irregular lawns
- Only effective if applied in early spring, reducing flexibility
Best for: Homeowners with St. Augustine, Centipede, or Zoysia lawns who want an easy, combined weed control and fertilization solution in early spring.
Not ideal for: Owners of Bermudagrass or lawns outside the specified grass types, since it’s not formulated for those species and could cause damage or ineffective results.
- Type:Weed & Feed
- N-P-K Ratio:15-0-4
- Weight:25.6 lbs
- Coverage:5,000 sq ft
- Suitable for:St. Augustine, Centipede, Zoysia lawns
Our verdict“This product suits homeowners with specific warm-season grasses seeking targeted weed control and lawn feeding, but it’s not a universal solution.”
How We Picked
Products were evaluated based on their effectiveness in weed prevention, ease of application, coverage area, formulation quality, and value for money. We prioritized products that deliver consistent results with minimal user effort and examined customer feedback and expert recommendations. The ranking reflects a balance between performance, affordability, and versatility, ensuring options suitable for different lawn sizes and user expertise. Higher-ranked products tend to offer better coverage, longer-lasting results, and ease of use, making them more suitable for a broader range of buyers.Factors to Consider When Choosing Preemergent Herbicide Plus Fertilizer
When selecting a preemergent herbicide plus fertilizer, it’s important to consider several factors beyond just price. First, think about your lawn size to ensure the product’s coverage matches your needs. Next, evaluate the weed spectrum—some products target specific weeds like crabgrass, while others provide broader control. Application ease can save time and effort, especially for larger lawns. Also, consider the nutrient content to support ongoing lawn health. Finally, weigh long-term effectiveness versus upfront cost, and read labels carefully to avoid over-application or damage to desirable plants.Coverage Area and Application Method
Matching the product’s coverage area with your lawn size ensures you don’t overspend or leave sections untreated. Granular products typically require less frequent applications and are easier to spread evenly, especially with a broadcast spreader. Liquid formulations may offer faster results but often need more precise application techniques. Larger lawns benefit from bulk-sized packages, but they may come with higher upfront costs. Small or irregularly shaped lawns might prefer smaller or more precise applicators to avoid waste and ensure effective coverage.
Weed Spectrum and Effectiveness
Some preemergent herbicides target specific weeds like crabgrass, while others offer broader spectrum control against various annual grasses and broadleaf weeds. The choice depends on your lawn’s weed pressure—if crabgrass is a recurring problem, select a product known for reliable crabgrass prevention. Combining fertilizer with weed control can be advantageous, but ensure the herbicide’s active ingredients are compatible with your lawn type. Consider formulations with proven long-term efficacy, especially if weed pressure is high or persistent.
Ease of Application and User Experience
Ease of use can significantly influence how consistently you apply the product and achieve desired results. Granular products are generally straightforward with broadcast spreaders, making them suitable for DIYers. Liquid options might require sprayers or nozzle adjustments, which can be challenging for beginners. Timing is also critical; applying too early or late can reduce effectiveness. Readability of instructions and the availability of application tools should influence your choice, especially if you prefer a hassle-free experience.
Nutrient Content and Lawn Health
Fertilizer ingredients vary, with some products providing balanced nutrients to promote healthy turf growth, while others focus solely on weed prevention. The nitrogen, phosphorus, and potassium ratios should match your lawn’s needs—for example, lawns needing more nitrogen for lush growth benefit from higher-urea formulations. Be cautious of high-phosphorus products unless soil tests indicate a deficiency, as excess can harm the environment. Combining weed control with fertilization can be cost-effective but requires selecting formulations that won’t interfere with each other’s efficacy.
Long-term Effectiveness and Cost Tradeoffs
Long-lasting weed prevention can reduce the frequency of applications, saving time and money over the season. However, premium products with extended efficacy often come at higher upfront costs. Cheaper options might require more frequent reapplication, which can add to ongoing expenses and effort. Consider your lawn’s weed history and your willingness to apply multiple treatments—sometimes investing in a more durable product pays off through less maintenance and better results over time.
Frequently Asked Questions
Can I apply preemergent herbicide plus fertilizer on a newly seeded lawn?
Applying preemergent herbicide immediately after seeding is generally not recommended, as it can prevent seed germination. Most products specify a waiting period after seeding—often around 4-6 weeks—before application. Fertilizer can be applied sooner, but its timing should align with your lawn’s growth stage and the product instructions. Always check the label for specific guidance on pre- and post-seeding applications to avoid inadvertently harming new grass.
How often should I reapply preemergent herbicide and fertilizer during the season?
The frequency depends on the product’s longevity and your lawn’s weed pressure. Many granular preemergents last around 3-4 months, so applications every 2-3 months are common for season-long control. Fertilizer is often applied every 6-8 weeks during active growing seasons. Combining the two means scheduling reapplications carefully to maintain weed prevention without over-application, which can damage the lawn or waste money. Always adhere to label instructions for best results.
Will these products harm my existing garden beds or landscaping?
Most preemergent herbicides are formulated to target specific weed seeds and generally won’t harm established plants if used correctly. However, drift or runoff during application can affect nearby plants, especially if they are sensitive or young. Using proper application techniques, such as avoiding windy days and following recommended distances, minimizes risks. Always read the label for precautions, and consider applying these products when wind or rain are unlikely to cause drift toward flower beds or shrubs.
Can I use these products on all types of lawns?
Many preemergent herbicides are suitable for a range of grass types, but some formulations are optimized for specific turfgrass species, such as Kentucky bluegrass or St. Augustine. Always check the product label to ensure compatibility with your lawn type, especially if you have a sensitive or ornamental grass. Incorrect use can lead to lawn damage or reduced effectiveness. If you have a specialized lawn, consulting local extension services or lawn care professionals can help you choose the safest option.
Are there environmentally friendly or organic options available?
While most preemergent herbicides are synthetic, some organic or natural options aim to control weeds without chemicals. These typically include corn gluten meal or other natural mulching methods, but they often lack the broad-spectrum efficacy of chemical products. If you prefer environmentally conscious lawn care, carefully review labels for organic certifications or eco-friendly claims. Keep in mind that organic options may require more frequent applications and may not provide the same level of weed prevention as conventional products.
Conclusion
The best choice depends on your lawn’s size, weed pressure, and experience level. For overall reliability and ease of use, The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control is the top pick, offering consistent results for most homeowners. Budget-conscious buyers will appreciate the 5-0-30 Pre-Emergent Weed Control & Lawn Fertilizer for its balance of price and performance. Those seeking premium, long-lasting control should consider products like Prodiamine 65 WDG, which offer extended protection but at a higher cost. Beginners or small lawn owners might prefer simpler liquid formulations, while larger properties should prioritize coverage size and ease of application. Ultimately, selecting the right product involves balancing your specific lawn needs, budget, and desired convenience to achieve a healthy, weed-free yard.
