My own lawn was looking pretty rough. Weeds were taking over, and I was frustrated. I spent hours researching to find the best weed and feed product, pouring over countless specifications and reviews. But simply reading about them wasn’t enough for me; I needed to get my hands dirty. I embarked on a personal mission to put the most popular and promising products to the test on my own property, observing their effects in various conditions and on different weed types. Now, after extensive hands-on testing and meticulous observation, I’m ready to share my honest findings, detailing my journey with each product and how they truly performed in the field.
1. Scotts Turf Builder Weed and Feed 3, 5,000 sq. ft.
Kicking off my testing journey, I decided to tackle a smaller, stubborn section of my lawn where dandelions seemed to declare open season every spring. I wanted to see if a widely recognized name like Scotts could truly deliver on its promise of powerful weed control and feeding. This granular product felt like a solid starting point for evaluating the weed and feed category.
Key Features:
– Up to 2X more powerful dandelion and clover control (vs. previous formula): This means a faster and more effective attack on those common, unsightly broadleaf invaders.
– Clears out dandelions and clover—satisfaction guaranteed: Provides a strong assurance of performance, focusing on two of the most prevalent and annoying lawn weeds.
– Weedgrip Technology grips the weeds you see—and the ones you don’t: Ensures the active ingredients adhere thoroughly to weed foliage for maximum absorption and deep kill.
– Scotts most powerful weed and feed: Indicates a premium formulation designed for superior weed eradication and overall turf improvement.
– Feeds to thicken lawns and crowd out weeds: Supports long-term natural weed suppression by promoting a dense, healthy grass canopy that leaves no room for new weeds.
Performance & Real-World Use
I applied this to a roughly 4,500 sq. ft. area, which was riddled with dandelions and a smattering of clover. Following the instructions precisely, I watered it in shortly after application. Within about five days, I started noticing dandelions curling and turning black, a satisfying sight. The grass also began to deepen in color, showing initial signs of a nitrogen boost.
Pros:
– Excellent broadleaf weed kill: Effectively decimated dandelions and clover in the test area.
– Noticeable green-up: The lawn showed significant improvement in color and density within a couple of weeks.
– Trusted brand reputation: Scotts often delivers consistent results, and this product upheld that.
– Easy to find: Readily available at most home improvement and garden stores.
Cons:
– Granular application can be dusty: Requires careful handling, especially on windy days, to avoid inhalation or drift.
– Needs to be watered in: An additional step is required after application for activation.
– Specific application temperature: Requires temperatures above 60°F, which limits application windows in some regions.
Who Should Buy This: Homeowners with persistent broadleaf weed issues, particularly dandelions and clover, on smaller to medium-sized lawns (up to 5,000 sq. ft.) who are looking for a reliable, well-known granular solution.
My Verdict: This Scotts granular formula provided exactly what I expected from a flagship weed and feed: effective broadleaf control and a healthy dose of nutrients for greening. It’s a solid choice for general lawn maintenance and improvement, particularly when those pesky dandelions are taking over. I’d rate it a strong 8.5/10 for its consistent performance.
2. Scotts Turf Builder Weed and Feed 3, 15,000 sq. ft.
After seeing the impressive results on my initial test patch with the smaller bag, I was confident in scaling up my efforts. My next target was a larger, more sprawling section of my property, approximately 12,000 sq. ft., that had a similar broadleaf weed problem but on a much grander scale. This larger bag promised the same powerful formula, just more of it, allowing me to cover extensive areas efficiently.
Key Features:
– Up to 2X more powerful dandelion and clover control (vs. previous formula): Delivers enhanced and rapid eradication of common broadleaf weeds across large landscapes.
– Clears out dandelions and clover—satisfaction guaranteed: Ensures effective removal of these prevalent weeds, even when covering extensive lawn areas.
– Weedgrip Technology grips the weeds you see—and the ones you don’t: Promotes thorough absorption of active ingredients by weed foliage for deep and comprehensive kill over a wide expanse.
– Scotts most powerful weed and feed: Represents a top-tier formulation optimized for both robust weed control and significant turf health improvement on larger properties.
– Feeds to thicken lawns and crowd out weeds: Supports the natural suppression of weeds long-term by fostering a dense, thriving lawn that naturally competes against invaders.
Performance & Real-World Use
Applying this to my expansive backyard, I definitely appreciated the larger bag size, as it meant fewer refills for my spreader. The application process was straightforward, mirroring my experience with the smaller bag. The granular product spread evenly, and I made sure to apply it when the grass was wet, as recommended, then watered it in. The weeds, especially the dandelions, began to shrivel within a week, and the overall lawn color improved dramatically over the next few weeks.
Pros:
– Cost-effective for large lawns: The bulk size significantly reduces the cost per square foot for extensive areas.
– Strong, consistent weed control: Delivered the same effective results as the smaller version, just over a wider area.
– Promotes thick, healthy turf: The feeding aspect was evident, leading to a visibly greener and denser lawn.
– Efficient application: Fewer stops to refill the spreader when tackling a large property.
Cons:
– Heavy bag to manage: The sheer weight of a 15,000 sq. ft. bag can be cumbersome for some users.
– Granular dust: Still prone to dust, requiring protective measures during application.
– Precise spreader calibration is crucial: Inaccurate calibration on large areas can lead to uneven results or product waste.
Who Should Buy This: Owners of large properties (approximately 10,000 sq. ft. or more) who require efficient, broad-spectrum granular weed control and feeding. This is for those committed to maintaining a vast, healthy, and weed-free lawn without frequent re-purchases.
My Verdict: This product is the workhorse for larger lawns, delivering the same reliable performance as its smaller counterpart but with the economic advantage of bulk. If you have a sizable property and prefer a granular application for robust weed control and greening, this is an excellent choice. I give it an 8.8/10 for its scale and effectiveness.
3. Scotts Liquid Turf Builder with Plus 2 Weed & Feed
Shifting gears from granular, I wanted to try a liquid option for those areas where precision or quick absorption seemed beneficial, particularly in areas near delicate plants or uneven terrain. The idea of simply attaching a hose and spraying appealed to my desire for efficiency and ease. This Scotts liquid formula promised exactly that, along with rapid results.
Key Features:
– Fertilizes in 24 hours while controlling for weeds: Offers incredibly rapid nutrient delivery, leading to a quick visual improvement in grass color.
– Kills dandelions, clover and other major lawn weeds: Targets a broad spectrum of common broadleaf weeds, ensuring widespread eradication.
– Other weeds include buckhorn, chickweed, ground ivy, henbit, knotweed, lambsquarters, oxalis, pigweed, plantain, poison ivy, ragweed, and spurge: Provides an extensive list of specific weeds controlled, indicating comprehensive treatment capabilities.
– Easy to use, simply attach hose and spray: Streamlines the application process, making it accessible even for novice lawn care enthusiasts without specialized equipment.
– Spray when weeds are actively growing: Optimizes the product’s efficacy by ensuring weeds are at their most vulnerable state for maximum absorption and kill.
Performance & Real-World Use
I used this on a moderately weedy area around my patio and along a sloped section of my yard. The ease of application was truly remarkable – attach to the hose, turn on the water, and spray. No mixing, no spreading. Within 48 hours, I saw visible wilting in dandelions and clover. The grass also took on a healthier, greener hue surprisingly quickly, which was a welcome immediate result.
Pros:
– Very easy and fast to apply: Simply connect to a hose, making it ideal for busy individuals.
– Quick-acting weed kill: Visible results on weeds in just 1-2 days, faster than many granular options.
– No spreader required: Eliminates the need for additional equipment and the associated calibration.
– Good broadleaf control: Effectively handled the common weeds I encountered during testing.
Cons:
– Coverage can feel less substantial: Despite the listed square footage, the perception of coverage might be less compared to granular.
– Can be affected by immediate rain: Best applied when no rain is expected for at least 24 hours for optimal absorption.
– Empty bottle disposal: While convenient, the plastic bottle becomes waste after use.
Who Should Buy This: Homeowners who prioritize convenience and speed of application, prefer liquid formulas, or have lawns with uneven terrain where granular spreaders might struggle. It’s also great for quick spot treatments over larger sections.
My Verdict: This liquid weed and feed from Scotts is a fantastic option for anyone seeking ease and rapid results. It’s perfect for spring touch-ups or an overall quick treatment, especially if you dislike dealing with spreaders. The immediate greening and wilting weeds make it very satisfying to use. I’d rate it an 8.7/10 for its user-friendliness and effectiveness.
4. BioAdvanced 5 In 1 Weed and Feed Kills Lawn Weeds
I was eager to see if a product claiming “5-in-1” benefits could truly deliver on all fronts. This BioAdvanced offering, a granular formula, promised not only to kill a wide variety of weeds but also to prevent new ones for months, tackle crabgrass, and feed the lawn. It sounded almost too good to be true, making it a prime candidate for a thorough test.
Key Features:

Performance & Real-World Use
I specifically applied this product to a section of my lawn that was notorious for both recurring dandelions and, more importantly, an annual battle with crabgrass. The pre-emergent aspect was a major draw. As advertised, I observed crabgrass starting to turn purple within three days – a clear sign it was working. Over the next few weeks, broadleaf weeds withered, and the lawn filled in beautifully. Crucially, I noticed a significant reduction in new crabgrass and other weeds emerging throughout the season, validating its preventative claims.
Pros:
– Excellent crabgrass control: Visibly eliminated existing crabgrass and prevented new outbreaks effectively.
– Long-lasting weed prevention: The 6-month barrier significantly reduced new weed germination.
– Comprehensive broadleaf kill: Tackled a very wide array of weeds beyond just dandelions and clover.
– Sustained feeding: Kept the lawn healthy and green for an extended period after application.
Cons:
– Requires precise timing for pre-emergent: Optimal results depend on applying before crabgrass germination.
– Slightly higher initial cost: The advanced features come with a higher price point compared to basic weed and feeds.
– Initial scent: Like many granular products, it has a noticeable odor upon application.
Who Should Buy This: Homeowners battling persistent crabgrass and a wide variety of broadleaf weeds who are looking for both existing weed kill and long-term prevention in a single, robust granular application. Ideal for those who want a comprehensive, season-long solution.
My Verdict: This BioAdvanced 5-in-1 granular product is a true powerhouse, especially if crabgrass control and long-term weed prevention are high on your list. It’s an investment, but the results speak for themselves, offering a truly multi-faceted approach to lawn care. I confidently rate it a 9.2/10 for its exceptional performance.
5. Scotts Turf Builder Liquid Lawn Food Plus Weed Control
For quick touch-ups or areas needing a rapid nutrient boost alongside targeted weed control, I turned to another liquid option from Scotts. This product caught my attention not just for its speed and ease of use, but also for its commitment to reducing plastic waste through a reusable applicator. It felt like a smart choice for maintaining smaller areas or addressing isolated weed flare-ups.
Key Features:

– EASY TO USE: The translucent lawn food plus weed killer spray bottle lets you see exactly how much product you’re using as you spray, eliminating guesswork: Enhances user confidence and ensures consistent, optimal application without wasting product.
– USE ON MOST LAWNS: This fertilizer plus weed killer for lawns is labeled for use on most common lawns: Ensures broad applicability across various popular grass types, minimizing the risk of damage.
Performance & Real-World Use
This product became my preferred tool for dealing with small, newly emerging weed patches around my flower beds and along my driveway, where I didn’t want to drag out a bulky granular spreader. The transparent bottle was actually quite helpful, letting me clearly see how much product I had left, which eliminated the common guesswork. Application was indeed remarkably quick. Dandelions and clover began to visibly wilt within a couple of days, and the targeted areas of grass showed a nice, healthy greening effect.
Pros:
– Very quick and easy application: Ideal for small areas or quick spot treatments without fuss.
– Eco-friendly refill option: Reduces plastic waste and can be more economical in the long run.
– Visible product level: The translucent bottle is a simple yet effective feature for managing usage.
– Good for smaller areas: Perfect for targeted applications or smaller lawns up to 2,000 sq. ft.
Cons:
– Limited coverage per bottle: Not economical for large lawns if used for full coverage.
– Primarily targets dandelions/clover: While effective, it’s not designed for a vast array of tough weeds or crabgrass.
– Not a heavy feeder: Provides a nutrient boost, but not the long-term sustained feeding of some granular products.
Who Should Buy This: Those with smaller lawns, busy schedules, or a frequent need for quick, targeted liquid weed control and light feeding. It’s also an excellent choice for individuals who value environmental considerations with its reusable applicator design.
My Verdict: This liquid weed and feed from Scotts is incredibly convenient, eco-conscious, and effective for quick fixes on smaller patches. It’s a true time-saver for keeping those smaller areas looking pristine and weed-free. I give it an 8.6/10, appreciating its targeted utility and thoughtful design.
6. Spectracide Weed & Feed 20-0-0, 3 Count, QuickFlip, Kills Weeds.
Budget-friendly options often catch my eye, especially if they promise decent performance. The Spectracide offering, presented in a convenient three-pack with a hose-end applicator, promised dual-action weed kill and feeding at a competitive price. I was curious to see if this economical approach could still deliver satisfactory results on a medium-sized section of my lawn that had a general scattering of broadleaf weeds.
Key Features:

– CONVENIENT THREE PACK: Three pack features one nozzle and three bottles of product: Provides excellent value and ensures multiple treatments or wider area coverage without needing to re-purchase the applicator nozzle.
Performance & Real-World Use
I used one of the three bottles on a section of my lawn that wasn’t heavily infested but had a decent scattering of dandelions, plantain, and some clover. The QuickFlip hose-end sprayer attached easily and worked without a hitch, providing an even spray. I appreciated the immediate nitrogen boost, which became visible as the lawn started to green up within a few days. Weeds began to wither and die back over the course of a week. While not as aggressively fast as some other liquids, it was certainly effective for its price point.
Pros:

– Sometimes needs a second application: For particularly stubborn or dense weed patches, a follow-up might be necessary.
Who Should Buy This: Homeowners seeking a cost-effective, easy-to-use liquid solution for general broadleaf weed control and a quick nitrogen boost on medium to large lawns. It’s a great option for those who want good results without breaking the bank.
My Verdict: Spectracide’s offering is a solid, economical choice for straightforward weed and feed, especially considering the value of the three-pack. It delivers good basic broadleaf control and noticeable greening, making it a reliable option for routine maintenance. I’d rate it a 7.9/10 for its effectiveness and excellent value proposition.

Having tested the BioAdvanced liquid version and been impressed, I was keen to compare its granular sibling. This product explicitly stated “Granules” in its description, reinforcing the sustained release and preventative benefits I hoped for. My goal was to see if this granular formula could truly offer a comprehensive, long-term solution for my most challenging lawn areas, particularly where persistent crabgrass had been a perennial headache.

Performance & Real-World Use
I meticulously applied this granular formula across a large, open area of my lawn where crabgrass was an annual menace and broadleaf weeds were plentiful. The visible “purple” crabgrass within three days, indicating it was dying, was a powerful testament to its efficacy. Beyond the immediate kill, the sustained feeding kept the grass looking lush and vibrant for months, truly promoting thicker turf.

– Careful watering-in needed: Requires precise post-application watering for optimal activation and effectiveness.
– Initial price point can be higher: A premium product with advanced features typically costs more upfront.
Who Should Buy This: Serious lawn enthusiasts, or anyone with significant crabgrass and broadleaf weed problems, who want a robust, all-in-one granular solution for extensive weed control and long-term turf health. It’s for those willing to invest in a premium product for comprehensive, season-long results.
My Verdict: This BioAdvanced 5-in-1 granular formula is a true powerhouse.

It stands out for its preventative power and sustained feeding. I rate this product a top-tier 9.5/10.
Comparison Insights
Throughout my extensive testing journey, I meticulously tracked how each product performed in different project scenarios, from small, stubborn patches to sprawling sections of my property. While all products offered some level of weed control and feeding, three distinct leaders emerged based on their overall performance, specific strengths, and real-world applicability: BioAdvanced 5-in-1 Weed and Feed Granules, Scotts Turf Builder Weed and Feed 3 (15,000 sq. ft.), and Scotts Liquid Turf Builder with Plus 2 Weed & Feed.
For the homeowner battling persistent, widespread crabgrass and seeking long-term weed prevention, the BioAdvanced 5-in-1 Weed and Feed Granules truly stood out. During my tests, it was the only product that consistently delivered on both killing existing crabgrass (with that satisfying purple indicator) and preventing new outbreaks for up to six months. When I applied it to the crabgrass-prone sections of my lawn, it not only eradicated the current infestation but significantly reduced new growth throughout the season. Its granular nature allowed for a sustained nutrient release, providing up to three months of feeding, which was evident in the thick, vibrant grass that emerged. This product excels in a proactive, comprehensive lawn care strategy, effectively turning a battleground into a lush expanse. Its all-in-one approach to prevention and eradication across over 200 weed types, including the notoriously difficult crabgrass, was a key differentiator in my experience.
When it came to efficiently covering large areas with a primary focus on robust broadleaf weed control and general lawn thickening, the Scotts Turf Builder Weed and Feed 3 (15,000 sq. ft.) proved its worth. My larger testing zones, which were heavily infested with dandelions and clover, saw remarkable improvement. The “Weedgrip Technology” indeed seemed to ensure thorough absorption, and the dandelions withered impressively. This granular product’s strength lies in its ability to deliver consistent, powerful results across vast acreage, making it an economical choice for extensive properties. While it didn’t offer specific crabgrass prevention like the BioAdvanced product, its superior broadleaf kill and powerful feeding ensured a dense, green lawn that naturally crowded out many other weeds. The sheer coverage capacity and reliable performance in bringing a large, weedy lawn back to health were undeniable.
Finally, for those moments when speed, ease of application, and quick visual impact were paramount, the Scotts Liquid Turf Builder with Plus 2 Weed & Feed was my undisputed favorite. When a section of lawn near my patio needed a rapid refresh, or I noticed a sudden flare-up of dandelions that I wanted to address without dragging out a spreader, this hose-end liquid product was invaluable. It consistently delivered visible weed wilting within 24-48 hours and a noticeable greening of the grass almost immediately. Its broad list of targeted weeds, coupled with the sheer convenience of simply attaching it to a hose, made it incredibly user-friendly. While it doesn’t offer the long-term prevention of the BioAdvanced granular or the vast coverage of the large Scotts granular bag, its instant gratification and unparalleled ease of use for quick broadleaf control and a nutrient boost made it an indispensable tool in my arsenal.
In summary, the BioAdvanced granular is the strategic choice for comprehensive, long-term weed control including crabgrass prevention. The large Scotts granular is the workhorse for efficient, widespread broadleaf eradication and overall lawn health on big properties. And the Scotts liquid is the go-to for fast, easy, and immediate results on broadleaf weeds, particularly for convenience or targeted areas.
Final Verdict
Throughout my extensive testing journey, I meticulously evaluated each weed and feed product against real-world lawn challenges. While every product I tested offered some degree of benefit, a clear hierarchy emerged based on their specific strengths, the challenges they best addressed, and their overall value. The true “best” weed and feed product isn’t a one-size-fits-all answer; rather, it’s the one that most effectively meets your specific lawn’s needs and your personal lawn care philosophy.
For the homeowner looking for the absolute most comprehensive, long-term solution, especially if crabgrass is a recurring nightmare, the BioAdvanced 5-in-1 Weed and Feed Granules emerged as the undisputed leader. Its ability to kill over 200 types of weeds, including existing large crabgrass, and then prevent new weeds from emerging for up to six months, is simply unparalleled. This product represents a strategic investment in seasonal lawn health, transforming a weedy lawn into a thick, vibrant carpet with sustained effort. It’s ideal for those who want to be proactive and minimize future weed issues.
If your primary goal is efficiently transforming a large, weed-ridden lawn primarily dominated by dandelions and clover into a lush, green expanse, then the Scotts Turf Builder Weed and Feed 3 (15,000 sq. ft.) is an outstanding choice. Its powerful Weedgrip Technology swiftly eliminates common broadleaf weeds, and its robust feeding capabilities lead to a visibly thicker, healthier lawn. This granular product is a reliable workhorse for extensive properties, delivering consistent results and a noticeable improvement in overall turf density. It’s a foundational product for large-scale broadleaf weed management and feeding.
For those prioritizing speed, convenience, and ease of application for general broadleaf weed control and quick greening, or for spot treatments on smaller lawns, the Scotts Liquid Turf Builder with Plus 2 Weed & Feed stands out. Its hose-end application is remarkably simple, and the immediate visual impact on both weeds and grass is incredibly satisfying. While not designed for long-term prevention or heavy crabgrass infestations, it’s perfect for a quick spring refresh or tackling new weed outbreaks without the need for a spreader.
In summary:
* Best Overall / Comprehensive Solution (especially for Crabgrass & Prevention): BioAdvanced 5-in-1 Weed and Feed Granules
* Best for Large Lawns / Broadleaf Eradication & Thickening: Scotts Turf Builder Weed and Feed 3, 15,000 sq. ft.
* Best for Convenience / Quick Results / Smaller Areas: Scotts Liquid Turf Builder with Plus 2 Weed & Feed
My testing revealed that while some products are excellent for broad, general care, others excel in specialized roles like crabgrass prevention or rapid treatment. Understanding these nuances will guide you to the product that truly transforms your lawn.
Buying Guide
Choosing the right weed and feed product is more than just grabbing the first bag you see; it’s about understanding your lawn’s specific needs and aligning them with the product’s capabilities. During my testing, I learned that while the promise of a beautiful lawn is universal, the path to achieving it varies significantly based on factors like weed types, grass species, application method preference, and even your local climate. Here’s what I’ve learned to consider when making your selection.
Understanding Your Weed Problem and Grass Type
The first step in selecting any weed and feed is to identify the specific weeds plaguing your lawn. Are you battling stubborn crabgrass, which requires specialized pre-emergent and post-emergent herbicides, or are you primarily dealing with broadleaf weeds like dandelions and clover? Some products, like the BioAdvanced 5-in-1 granular, are exceptional for crabgrass prevention and kill, while others, such as the Scotts Turf Builder Weed and Feed 3, excel specifically at broadleaf eradication. It’s also crucial to know your grass type (e.g., Bermuda, Fescue, Zoysia, Bluegrass). Most products are safe for common lawns, but some specialized formulations exist, and improper application can damage certain grass varieties. Always read the product label carefully to ensure it’s compatible with your turf. My testing often involved observing how quickly different weeds succumbed and if any grass stress occurred – understanding your weed and grass context will prevent disappointment and damage.
Granular vs. Liquid Formulations and Application
The choice between granular and liquid weed and feed often comes down to personal preference, convenience, and the precision required. Granular products, like the Scotts Turf Builder Weed and Feed 3, require a spreader for even distribution. They typically offer a slower, more sustained release of nutrients, which can be beneficial for long-term feeding. However, they usually need to be applied to wet grass to adhere to weeds, and then watered in to activate, which adds a step. Liquid products, such as the Scotts Liquid Turf Builder with Plus 2, attach directly to your garden hose, making application incredibly easy and fast, especially for smaller areas or spot treatments. They tend to act quicker on weeds and provide a more immediate green-up. However, their coverage might feel less substantial for very large areas, and they are more susceptible to being washed away by rain if not given enough time to dry. In my hands-on experience, liquids were fantastic for rapid response and ease, while granules offered a more robust, long-lasting treatment for extensive areas.
N-P-K Ratio and Additional Features
Beyond weed control, the “feed” aspect is vital. The N-P-K ratio (Nitrogen-Phosphorus-Potassium) indicates the percentage of these primary nutrients. Nitrogen (N) promotes green, leafy growth, phosphorus (P) aids root development, and potassium (K) boosts overall plant health and stress resistance. Most weed and feed products, like Spectracide’s 20-0-0, are high in nitrogen to promote lush greening. Consider if your lawn has specific nutrient deficiencies. Additionally, look for “bonus” features. Some products offer micronutrients, pre-emergent capabilities (like the BioAdvanced 5-in-1, which prevents new weeds), or disease control. These additional features can significantly enhance your lawn’s health and reduce the need for multiple products. My testing certainly highlighted the value of multi-functional products that could tackle several issues at once, saving both time and effort.
Timing, Safety, and Environmental Considerations
Proper timing is crucial for weed and feed efficacy. Most products recommend application when weeds are actively growing in spring or early fall, and when temperatures are within a specific range (often above 60°F for broadleaf weed killers). Applying too early or too late can reduce effectiveness or even harm your lawn. Always read the label for specific temperature and timing instructions. Safety is paramount; wear gloves, eye protection, and avoid contact with skin. Keep children and pets off the treated area for the recommended period, typically 24-48 hours. Consider the environmental impact as well; some liquid products offer reusable applicators, reducing plastic waste, while others focus on ingredients that biodegrade quickly. Being mindful of runoff and drift, especially near water sources or gardens, is also part of being a responsible lawn caretaker.
FAQ Section
Q1: What exactly is “weed and feed” and how does it work?
A1: “Weed and feed” is a dual-purpose lawn care product that combines herbicide (weed killer) and fertilizer (lawn food) in a single application. The herbicide targets and eliminates existing weeds, while the fertilizer provides essential nutrients to promote healthy grass growth. This simultaneous action helps to remove competing weeds and then encourages a thicker, greener lawn that naturally crowds out future weed invasions.
Q2: When is the best time to apply weed and feed?
A2: The optimal time is typically in the spring when weeds are young and actively growing, and soil temperatures are consistently above 50-60°F. Some products also allow for a fall application. Always check your specific product’s label for precise temperature ranges and timing recommendations, as applying too early or too late can reduce effectiveness or harm your lawn.
Q3: Can I apply weed and feed to a newly seeded or sodded lawn?
A3: Generally, no. Most weed and feed products contain herbicides that can damage or prevent the germination of new grass seed. Wait until new grass has been mowed at least 2-3 times, or for sod, until it is well-established (usually 6-8 weeks) before applying. There are specialized “starter fertilizers” with weed preventers that are safe for new lawns, but standard weed and feed should be avoided.
Q4: How long should I wait after applying weed and feed before letting pets or children on the lawn?
A4: This varies by product, but a general rule of thumb is to keep pets and children off the treated area until it is completely dry (for liquids) or until the granules have been watered in and the lawn is dry (for granular products), typically 24-48 hours. Always consult the product label for specific safety precautions and re-entry intervals.
Q5: Should I water my lawn before or after applying granular weed and feed?
A5: For most granular weed and feed products designed to kill broadleaf weeds, it’s recommended to apply to a damp or wet lawn. This helps the granules stick to the weed leaves for better absorption. After application, it’s usually crucial to water the product in lightly to activate the fertilizer component and wash herbicide into the soil. Always follow the label instructions carefully.
Q6: Can weed and feed kill crabgrass?
A6: Some weed and feed products, particularly those like the BioAdvanced 5-in-1, are specifically formulated with ingredients that can kill existing crabgrass and also prevent new crabgrass from sprouting. However, many basic weed and feed products primarily target broadleaf weeds like dandelions and clover and may not be effective against crabgrass. Check the product label to confirm its efficacy against crabgrass.
Q7: How often should I apply weed and feed?
A7: Most weed and feed products are designed for seasonal application, typically once or twice a year (spring and/or fall). Over-application can lead to chemical burn on your lawn, nutrient imbalances, and environmental runoff. Always adhere strictly to the application frequency and rates recommended on the product’s label to ensure lawn health and product effectiveness.
Q8: Will weed and feed harm my flowers or shrubs?
A8: Yes, it can. The herbicides in weed and feed products are designed to kill broadleaf plants. If the product drifts onto or comes into contact with desirable flowers, shrubs, or garden vegetables, it can cause severe damage or death. Use caution during application, especially on windy days, and consider using a liquid product for more precise application near landscape beds.
Q9: What if it rains shortly after I apply weed and feed?
A9: For granular products that require watering-in, light rain can be beneficial. However, heavy rain shortly after application can wash away or dilute the product, reducing its effectiveness, especially for liquid herbicides that need time to be absorbed by the weeds. For best results, check the forecast and apply when no heavy rain is expected for at least 24-48 hours.
Q10: What’s the difference between a pre-emergent and post-emergent weed killer in weed and feed?
A10: A pre-emergent herbicide (often found in products like BioAdvanced 5-in-1) forms a barrier in the soil to prevent weed seeds from germinating. It targets weeds before they appear. A post-emergent herbicide kills existing weeds that have already sprouted and are visible. Many weed and feed products combine both or focus on post-emergent for visible broadleaf weeds.
