Detailed Reviews of the Best Granular Crabgrass Killers
Spectracide Weed Killer – Covers a large area; up to 3000 sq ft.
Clearly, this product offers several advantages for achieving a weed-free lawn. Its lightweight granular formula is designed for easy application with a hand-held spreader, ensuring smooth and even distribution without clogging. This makes the spreading process effortless, especially compared to heavier, clumping alternatives.
The granular form also offers a more effective application method compared to liquid sprays, which can be difficult to spread evenly due to droplet size and coverage. While multiple applications of weed killer may be necessary to achieve optimal results, this product effectively supports grass growth while controlling weeds. Although pre-application preparation, such as pulling tall weeds and mowing, is recommended, the product demonstrates a capacity to help establish a weed-free environment for grass to thrive.
A potential consideration is the bag size, as larger yards may require multiple bags to cover the entire area. While the product’s weed control may require repeated applications and may not eliminate established tall weeds, it provides a solution for maintaining a healthy lawn by targeting weeds without harming the grass. With consistent use, this product can contribute to a lawn free of weeds and promote healthy grass growth.

Scotts Halts Crabgrass and Grassy Weed Preventer – Prevents many common lawn weeds effectively.
My experience with this product has been overwhelmingly positive over the past ten years of managing my own lawn care. I discovered early on that pre-emergent control is the most effective strategy for preventing crabgrass, a common challenge for lawn enthusiasts. By incorporating this product into my lawn care routine, I’ve successfully maintained a crabgrass-free lawn.
The effectiveness of this pre-emergent weed control hinges on proper application: applying at the prescribed rate and timing the application approximately two weeks before soil temperatures rise enough for crabgrass germination. A helpful indicator is the blooming of forsythia bushes. Unlike weed and feed products commonly found in big box stores, this product focuses solely on pre-emergent weed control.
This is advantageous because early spring, while ideal for pre-emergent application, is not the optimal time for fertilizer application. Grass benefits most from fertilizer when it’s actively growing, which typically occurs more than a month after the ideal pre-emergent application window. Consulting your local university extension and co-op is invaluable for determining the correct application timing for your specific region.
Furthermore, maintaining a healthy lawn is crucial for weed prevention. A vigorously growing turf grass, such as Kentucky Bluegrass, can effectively outcompete weeds, including crabgrass. This pre-emergent control will keep crabgrass from taking over your lawn during periods of stress, such as drought.
I appreciate that this product, a pure pre-emergent, is available, as many companies prioritize combined weed and feed products. I’m pleased that Amazon carries this and hope they will continue to do so.
Pros
- Prevents many common lawn weeds effectively.
- Works all season long with one application.
- Application is simple and weather-resistant.
- Safe for use on most common grass types.
- One bag covers a large lawn area.
Cons
- Hard to find product
- Timing is very important
BONIDE PRODUCTS 60490 917453 Crabgrass Weed Killer – Wide coverage area, treats up to 5000 sq ft.
Ultimate lawn care solution that delivers surprisingly effective weed control. Despite initial skepticism, this product has proven its ability to transform weed-infested lawns into predominantly grass-filled areas. The product’s effectiveness is maximized when applied under optimal conditions, such as after recent rainfall.
Applying the product to grass still wet from rain allows it to target existing weeds effectively, while subsequent rainfall helps to water in the product, providing ongoing weed prevention. Noticeable results may take a week or two to appear, as the product gradually eliminates unwanted weeds. This product has demonstrated its ability to successfully eliminate common lawn weeds such as dandelions, henbit, and various prickly weeds.
While some areas may still experience weed growth and certain types of weeds, like wild rye, may not be affected, the overall results are highly satisfactory. The product’s ability to significantly reduce weed populations and promote a healthier, grass-filled lawn makes it a worthwhile investment for lawn care. Its ease of application and long-lasting effects contribute to a positive experience.
Pros
- Wide coverage area, treats up to 5000 sq ft.
- Convenient spray form for easy application.
- Trusted brand: Bonide, made in the USA.
- Large 192-ounce size offers great value.
Cons

BASF Drive XLR8 Crabgrass Killer for Lawn & Turf – Effective active ingredient, Quinclorac 18.92% for full coverage.
My take on the BASF Drive XLR8 concentrate is that it effectively controls crabgrass and a variety of other weeds when applied as directed. The product is easy to use, mixing readily with water according to the instructions. Application is simple, especially with a handheld sprayer, as it blends well with water, preventing clogs and streaks.
One of the key benefits is its ability to inhibit new crabgrass growth while visibly diminishing existing weeds within a week. This demonstrates the product’s fast-acting nature and effectiveness in weed control. Furthermore, it provides up to thirty days of residual control, reducing the need for frequent reapplication and offering long-lasting protection for your lawn.
While the product’s odor during application is noticeable, this can be easily managed by wearing a mask or ensuring you are upwind while spraying. This minor inconvenience is outweighed by the product’s other advantages. The product handles well during application and rinses easily from equipment afterward, ensuring a hassle-free cleanup process.
Overall, this herbicide delivers noticeable improvements in lawn health by effectively eliminating unwanted weeds without unnecessary complications. Its ease of use, efficient weed control, and long-lasting effects make it a valuable tool for maintaining a healthy and vibrant lawn.

Buying Guide: What to Look For in a Granular Crabgrass Killers
Understanding Crabgrass and Its Control
Crabgrass is a common, unsightly weed that can quickly take over lawns. Choosing the best granular crabgrass killers involves understanding the type of crabgrass in your region and the stage of its growth. Granular crabgrass killers are favored for their ease of application and even distribution, ensuring consistent coverage across your lawn. They work by either preventing crabgrass seeds from germinating (pre-emergent) or killing existing crabgrass plants (post-emergent). Effective control requires selecting the right product for your specific needs and following the application instructions carefully.
Key Considerations When Choosing
When selecting the best granular crabgrass killers, several factors should be taken into account. First, consider the size of your lawn to ensure the product covers the entire area effectively. Next, look at the active ingredients; some are better suited for pre-emergent control, while others are designed for post-emergent application. Pay attention to the product’s safety for your grass type and any potential impact on desirable plants. Lastly, consider the ease of application and the overall value offered by the product, including coverage area per bag or container.
Types of Granular Crabgrass Killers
Granular crabgrass killers fall into two main categories: pre-emergent and post-emergent. Pre-emergent herbicides are applied in early spring before crabgrass seeds germinate, preventing them from sprouting. These products typically contain ingredients like pendimethalin or dithiopyr. Post-emergent herbicides, on the other hand, are used to kill crabgrass that has already sprouted. These products often contain ingredients like quinclorac or dicamba. Selecting the appropriate type depends on whether you are trying to prevent crabgrass or eliminate existing infestations. Choosing the best granular crabgrass killers means knowing your lawn.
Application Techniques and Timing
Proper application is crucial for the effectiveness of best granular crabgrass killers. For pre-emergent herbicides, apply in early spring before soil temperatures reach 55 degrees Fahrenheit. Use a spreader to ensure even distribution across the lawn. Water the granules into the soil after application to activate the herbicide. For post-emergent herbicides, apply when crabgrass is actively growing, usually in late spring or early summer. Avoid applying during periods of drought or extreme heat. Always follow the product label instructions carefully for best results and to prevent damage to your lawn.
Frequently Asked Questions about Granular Crabgrass Killers
When is the best time to apply granular crabgrass killer?
The ideal timing depends on whether you’re using a pre-emergent or post-emergent product. For pre-emergent granular crabgrass killers, apply in early spring before crabgrass seeds begin to germinate, generally when soil temperatures reach around 55 degrees Fahrenheit. Post-emergent granular crabgrass killers should be applied when crabgrass is actively growing, typically in late spring or early summer. Always check the product label for specific timing recommendations based on the active ingredients and your local climate.
How do I apply granular crabgrass killer correctly?
Use a fertilizer spreader to ensure even distribution of the granules across your lawn. Calibrate the spreader according to the product label instructions to apply the correct amount. Avoid overlapping passes to prevent over-application, which could damage your grass. After applying, water the granules into the soil to activate the herbicide. Be sure to wear protective gear, such as gloves and eye protection, while handling the product. Sweep any stray granules off driveways and sidewalks to prevent staining.
Are granular crabgrass killers safe for my pets and children?
Most granular crabgrass killers pose some risk to pets and children if ingested or if they come into contact with treated areas before the product has dried or watered in. Always read and follow the safety precautions on the product label. Typically, it’s recommended to keep pets and children off the treated lawn until the granules have been watered in and the area is completely dry. Some products may have longer re-entry waiting periods, so it’s important to adhere to the manufacturer’s instructions.
What are the active ingredients in granular crabgrass killers?
Common active ingredients in granular crabgrass killers include dithiopyr, pendimethalin, quinclorac, and dicamba. Dithiopyr and pendimethalin are typically used in pre-emergent herbicides to prevent crabgrass seeds from germinating. Quinclorac and dicamba are often found in post-emergent herbicides designed to kill existing crabgrass plants. The specific active ingredient and its concentration will determine the product’s effectiveness and its suitability for different types of crabgrass and grass types.
Can I use granular crabgrass killer on all types of lawns?
Not all granular crabgrass killers are safe for all types of lawns. Some herbicides can damage or kill certain grass varieties. Before applying any product, carefully read the label to ensure it is safe for your specific grass type, such as Kentucky bluegrass, fescue, or Bermuda grass. If you are unsure, it’s best to test the product on a small, inconspicuous area of your lawn first to observe its effects before treating the entire area.
How long does it take for granular crabgrass killer to work?
The time it takes for granular crabgrass killer to work depends on the type of product (pre-emergent or post-emergent) and the specific active ingredients. Pre-emergent herbicides prevent crabgrass from emerging, so you won’t see immediate results. Post-emergent herbicides typically start to show effects within a few days to a week, with complete kill taking up to two weeks, depending on the size and maturity of the crabgrass plants. Weather conditions, such as temperature and rainfall, can also influence the product’s effectiveness.
Will granular crabgrass killer also kill my grass?
When applied correctly, granular crabgrass killer should not kill your grass, provided the product is specifically formulated for your grass type and you follow the label instructions carefully. Over-application or using the wrong product can damage or kill desirable grasses. Avoid applying during periods of drought or extreme heat, as this can increase the risk of lawn damage. Always calibrate your spreader accurately and apply the product evenly to prevent localized over-application.
How often should I apply granular crabgrass killer?
The frequency of application depends on the type of product and the severity of the crabgrass infestation. Pre-emergent herbicides typically require one application in early spring to provide season-long control. Post-emergent herbicides may require multiple applications, spaced several weeks apart, to effectively kill existing crabgrass plants. Refer to the product label for specific re-application intervals and guidelines. Over-application can harm your lawn, so it’s important to follow the manufacturer’s recommendations.
What are the benefits of using granular crabgrass killer over liquid?
Granular crabgrass killers offer several advantages over liquid formulations. They are generally easier to apply evenly, especially over large areas, using a fertilizer spreader. Granules also provide a more controlled release of the herbicide, reducing the risk of drift and off-target damage. Additionally, granular products are often less susceptible to wash-off from rain or irrigation compared to liquid formulations, making them more effective in certain weather conditions.
Can I apply fertilizer at the same time as granular crabgrass killer?
It depends on the specific products you are using. Some products, like “weed and feed” combinations, combine a crabgrass killer with fertilizer in a single application. However, it’s important to check the compatibility of the ingredients to ensure they won’t interact negatively or harm your lawn. If you are using separate products, it’s generally recommended to apply the crabgrass killer first and then wait a few days before applying fertilizer to allow the herbicide to properly absorb into the soil. Always follow the label instructions for both products carefully.

After careful consideration of all the options, we believe the Spectracide Weed Killer stands out as the best overall choice for most users. It offers an excellent balance of features, performance, and value.
