10 Best Fertilizer That Kills Weeds and Crabgrass for a Healthier Lawn in 2026

BioAdvanced 5-in-1 Weed and Feed Granules offer a straightforward solution for homeowners who want to simplify lawn care. This product combines four proven weed killers with a balanced fertilizer, targeting over 200 types of weeds including dandelions, clovers, and black medic, while also killing large crabgrass. It is designed for use on established lawns and covers up to 4,000 square feet per 9.6 lb bag, making it a practical choice for medium to large yards.

One of the standout features is its ability to prevent new weeds from emerging for up to six months. The granules create a protective barrier in the soil that stops listed weeds before they sprout, reducing the need for frequent reapplications. Additionally, the fertilizer component feeds your lawn for up to three months, promoting thicker, greener grass. This dual-action approach saves time and effort compared to using separate weed killers and fertilizers.

In terms of performance, the product works even if weeds and crabgrass have already sprouted, which is a major convenience. Users can apply it in spring or early summer and expect to see crabgrass start turning purple within three days, signaling that the treatment is working. The granules are easy to apply with a broadcast or drop spreader, and watering after application helps activate the ingredients.

However, there are a few trade-offs. You will need a spreader for even distribution, which adds to the initial cost if you do not already own one. Also, the granules must be watered in, so you need to plan around rain or irrigation. As with any combination product, it may not be as tailored as separate treatments for specific weed problems, and it is always wise to check the label for compatibility with your grass type and local regulations.

Overall, BioAdvanced 5-in-1 Weed and Feed Granules deliver a convenient, all-in-one approach to lawn care. They effectively kill weeds, prevent new growth, and nourish your grass, all in a single application. For homeowners looking to streamline their lawn maintenance without sacrificing results, this product is a solid choice.

Scotts Halts Crabgrass & Grassy Weed Preventer is a pre-emergent herbicide designed to stop crabgrass and other grassy weeds before they sprout. It's ideal for homeowners who want a straightforward, season-long solution without constant reapplication. The product comes in a 10.06-pound bag that covers up to 5,000 square feet, making it suitable for medium to large lawns.

The standout feature is its dual-season versatility. Apply it in early spring to prevent crabgrass and other summer weeds all season. Then, a fall application tackles winter weeds like poa annua, henbit, and chickweed, while also helping to prevent moss. This means one bag can serve two purposes depending on the time of year. The formula is designed to resist rain, snow, and freezing temperatures after application, so you don't have to worry about weather ruining your effort.

In terms of design, it's a granular product that works with any standard lawn spreader. There's no mixing or spraying, just even distribution across your lawn. The granules are consistent and spread easily, though you'll want to water lightly after application to activate the barrier. Build quality is typical for Scotts - reliable and well-tested in real-world conditions.

A key drawback is that this is a pre-emergent only. If you already see crabgrass or other weeds, this won't kill them. You'll need a post-emergent product for that. Also, timing is critical: apply too early and the protection may fade before peak germination; apply too late and weeds may already be growing. Following the label instructions for your region is essential.

Overall, Scotts Halts delivers dependable, season-long control when used correctly. It's a solid choice for preventively managing crabgrass and grassy weeds, and the fall benefit for winter weeds adds extra value. For the price, it's a cost-effective way to keep your lawn looking its best without constant maintenance.

The Scotts Turf Builder Triple Action1 is a straightforward solution for homeowners who want to simplify their lawn care routine. This 3-in-1 product combines a fertilizer, a broadleaf weed killer, and a pre-emergent crabgrass preventer in one bag. It's designed for people who tend to skip steps or just want to get the job done without keeping track of multiple products. The formula works on common grass types like Bermudagrass, Kentucky Bluegrass, Tall Fescue, and Zoysiagrass, which covers most of the country.

The standout feature here is the time savings. Instead of fertilizing, then waiting to apply weed killer, then adding a crabgrass preventer later, you do it all at once. It controls weeds like dandelion, clover, and dollarweed while feeding the grass to encourage thick growth. The crabgrass prevention lasts four months, which covers the critical spring and early summer window. Users should note that it won't kill existing crabgrass - that requires a separate post-emergent product. But for stopping new crabgrass from germinating, it's effective.

Application requires a bit of planning: you need to put it down on a wet lawn (right after rain or watering) and then water it in again after 24 hours. This helps activate the weed killer and fertilizer. A Scotts spreader is recommended for even distribution, but any calibrated broadcast spreader should work. The bag covers 4,000 square feet, which is fine for average-sized suburban lots. For larger lawns, you'll need multiple bags.

One potential drawback is that this is a chemical product. If you prefer organic lawn care or have pets that graze on the grass, you might want to look elsewhere. Also, because it combines multiple actions, you're locked into a single schedule - you can't delay the fertilizer if your lawn doesn't need it yet. But for most people looking for a simple, effective spring treatment, this is a solid choice.

Overall, the Scotts Turf Builder Triple Action1 delivers on its promises. It kills common weeds, prevents crabgrass, and feeds the lawn, all in one pass. It's not perfect for every situation, but for the typical homeowner who wants a healthier lawn with less effort, it's a reliable product that works.

Size: 4,000 sq. ft.
Dimensions: 15 x 10 x 4 inches
Weight: 0.5 pounds (bag)
Product Group: Lawn & Patio
Binding: Lawn & Patio

Each bag covers 4,000 square feet when applied at the recommended rate. For larger lawns, purchase additional bags as needed.

The Ortho WeedClear Lawn Weed Killer Ready-To-Spray is a dependable solution for homeowners battling broadleaf weeds and common grassy invaders like crabgrass. This 32-ounce concentrate attaches directly to your garden hose, turning it into a powerful sprayer that covers up to 5,000 square feet. It's designed for those who want an effective weed killer without the hassle of mixing or using a separate sprayer, making it a practical choice for routine lawn care.

What sets this product apart is its fast-acting formula that kills weeds down to the root. In my experience, it handles dandelions, clover, chickweed, and creeping charlie with noticeable results in about a week. The hose-end sprayer delivers an even coat, and the “on/off” switch lets you control the flow easily. Just make sure the weeds are young and actively growing for the best outcome; it's not as effective on mature or dormant plants.

Design-wise, the Ortho WeedClear is straightforward. The container doubles as the sprayer, so you don't need extra gear. The trigger is comfortable, and the hose connection feels secure. One potential drawback is that you have to be careful not to overspray onto flower beds or vegetable gardens, as it can harm desirable plants. Also, while it's safe for many common grass types, always double-check your specific grass variety on the label to avoid damage.

A minor con is that some stubborn weeds like established clover may require a second application. The product recommends waiting a few weeks before retreating. Because it's a ready-to-spray formula, you can't adjust the concentration like you could with a concentrate, but for most users, the preset ratio works well for general weed control. The bottle is lightweight and easy to store, though it doesn't come with a separate measuring cup or extension wand.

Overall, the Ortho WeedClear Lawn Weed Killer Ready-To-Spray delivers on its promise of fast, easy weed control for lawns. It's well-suited for homeowners who want a simple, effective tool to maintain a weed-free yard without spending hours on DIY mixes. Given its high rating and practical design, it's a solid choice for anyone looking to tackle annual weeds quickly and safely.

The Scotts Liquid Turf Builder with Plus 2 Weed Control is a two-in-one lawn care product that combines a quick-release nitrogen fertilizer with a broadleaf weed killer. It is designed for homeowners who want to simplify their lawn maintenance by feeding and controlling weeds in one step. The ready-to-spray formula works with a hose-end applicator, making it accessible even for those new to lawn care.

One of the key benefits is the rapid green-up from the nitrogen boost, which can make your lawn look healthier within days. The weed control component targets over 20 common broadleaf weeds, including dandelions, clover, chickweed, and ground ivy. This broad spectrum saves time compared to using separate products. The coverage of up to 6,000 square feet for warm-season lawns (or 4,000 for cool-season) means a single bottle can handle a typical suburban yard.

The hose-end applicator is straightforward: you attach the bottle to your garden hose, turn on the water, and spray. There is no mixing or measuring required, which reduces mess and guesswork. The applicator has a dial for selecting coverage rate, but it is not as precise as a pump sprayer. However, for most users, the convenience outweighs the slight lack of precision.

A notable limitation is that this product only kills broadleaf weeds. If your lawn is infested with grassy weeds like crabgrass or nutsedge, you will need a different herbicide. Additionally, the weed killer requires active growth to be effective, so timing applications is important. Some users may find that stubborn weeds need a second treatment. The coverage difference between warm and cool-season grasses also means you need to adjust your application rate.

Overall, the Scotts Liquid Turf Builder with Plus 2 Weed Control is a solid choice for routine lawn maintenance. It delivers on its promise of feeding and weeding simultaneously, with minimal effort. While not a cure-all for every lawn problem, it is a reliable tool for keeping broadleaf weeds at bay while promoting a greener lawn. For the price, it offers good value for homeowners who want a simple, effective solution.

BioAdvanced All-In-One Lawn Weed and Crabgrass Killer is a concentrated solution designed for homeowners who want to reclaim their lawn from stubborn weeds without damaging the grass. It targets over 200 broadleaf weeds and crabgrass, making it a versatile choice for most lawns.

The formula works by penetrating to the root, ensuring that weeds don't come back quickly. It becomes rainproof in just one hour, which is a major advantage for those unpredictable weather days. The all-in-one approach means you don't need separate products for different weed types.

As a concentrate, you mix it with water according to the instructions and apply using a sprayer. This allows for precise targeting and can cover a large area. The 40 oz bottle goes a long way, making it cost-effective. It's compatible with various grass types, so you don't have to worry about harming your lawn.

One potential downside is that it requires proper mixing and application equipment. If not applied carefully, it might affect nearby garden plants. Additionally, like many weed killers, it may take a couple of applications for particularly resilient weeds. Always follow the label directions.

Overall, the BioAdvanced All-In-One Lawn Weed and Crabgrass Killer is a reliable and efficient choice for maintaining a weed-free lawn. Its broad spectrum, root-killing action, and rainproof feature make it stand out. For the price, it offers solid value for homeowners seeking effective weed control.

Scotts Turf Builder Triple Action1 is a three-in-one granular lawn treatment designed for homeowners who want an efficient way to tackle weeds, prevent crabgrass, and feed their grass all at once. It is best applied in early spring when dandelions are actively growing and works on a wide range of common grass types including Bermuda, Fescue, Kentucky Bluegrass, and Zoysia.

The standout feature of this product is its convenience. Instead of spreading a weed killer, a crabgrass preventer, and a fertilizer separately, you get all three in one bag. It controls broadleaf weeds like dandelion, clover, and ground ivy while simultaneously stopping crabgrass from sprouting for up to four months. On top of that, the fertilizer promotes thick, green growth that helps your lawn resist future weed invasions.

Application is straightforward: use a Scotts spreader on a wet lawn, then water in the granules after 24 hours. The 33.94-pound bag covers 12,000 square feet, which is generous for most home lawns. The granules are easy to store and handle, and the bag includes clear instructions for setting your spreader correctly. One thing to note is that the product must be applied before crabgrass seeds germinate, so timing is important.

No product is perfect, and this one has a couple of honest limitations. It will not kill crabgrass that is already growing; it only prevents new crabgrass from emerging. Also, if you miss the watering requirement or apply to a dry lawn, results may suffer. Additionally, it is not recommended for certain grass varieties like St. Augustine or Bentgrass, so always check the label.

Overall, Scotts Turf Builder Triple Action1 is a solid choice for anyone looking for a simple, all-in-one spring lawn treatment. It delivers on its promises when used correctly, saves you time and money, and helps keep your lawn looking its best. If you have a medium to large lawn and value convenience over separate applications, this product is well worth considering.

GreenView Premium Formula Spring Fertilizer Weed & Feed and Crabgrass Preventer is a three-in-one lawn treatment designed for homeowners who want to simplify their spring lawn care. This 36-pound bag covers 10,000 square feet and combines a balanced 24-0-6 NPK fertilizer with pre-emergent crabgrass prevention and broadleaf weed control. It's best suited for established lawns of Kentucky bluegrass, perennial ryegrass, fine and tall fescues, as well as warm-season grasses like Bermuda, zoysia, and St. Augustine (excluding Floratam).

The standout feature is its season-long feeding. With 66.3% slow-release nitrogen and slow-release potassium, one application provides nutrients for up to six months. That means you don't have to reapply in midsummer. The fertilizer also includes Dimension, a reliable active ingredient that prevents crabgrass from germinating and kills young seedlings for up to four weeks after they appear. At the same time, it suppresses over 200 broadleaf weeds including dandelion, clover, and thistle, so you can tackle multiple problems in one pass.

In real-world use, the quick-release nitrogen delivers visible greening within days, while the slow-release portion keeps the color lasting. The potassium strengthens the grass roots, improving stress tolerance during hot, dry spells. One big plus is the no micro-plastic coating. Many slow-release fertilizers use plastic coatings that can linger in the soil, but GreenView uses a different technology that feeds longer without leaving residue. The formula also promotes even, steady growth rather than a sudden flush, which means less mowing and fewer clippings to manage.

There are a few drawbacks to consider. The bag is heavy at 36 pounds, so it might be awkward to carry and pour into a spreader. Also, the product is not recommended for Floratam St. Augustine grass, bentgrass, or newly seeded buffalograss. If you have those grass types, you'll need a different product. The price is on the higher side for a single bag, but given that it replaces a separate fertilizer, crabgrass preventer, and weed killer, the value is reasonable for the coverage area.

Overall, GreenView Premium Formula is an excellent choice for homeowners who want a straightforward, all-in-one spring treatment. It saves time, reduces the number of products you need to store, and delivers reliable results for most common lawn grasses. If your grass type is compatible and you're looking for a low-maintenance approach, this is a strong option.

The Scotts Turf Builder Weed and Feed5 is a combination weed killer and lawn fertilizer designed for homeowners who want to simplify their lawn care routine. Instead of applying separate products for weed control and feeding, this granular formula does both in one pass. It targets over 50 types of broadleaf weeds, including stubborn ones like dandelion, clover, plantain, and morningglory, while delivering nutrients to thicken and strengthen your grass. This product is ideal for lawns with grass types such as Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass, but it should not be used on St. Augustinegrass (including Floratam), Dichondra, Carpetgrass, or Bentgrass.

The standout feature here is the dual action. By killing weeds and feeding the lawn simultaneously, you save time and ensure your grass gets the nutrition it needs to recover and fill in bare spots. The formulation helps crowd out future weeds by promoting dense growth. Coverage is generous with an 11.32 pound bag covering up to 4,000 square feet, which is enough for a typical suburban lawn. Application is straightforward using a Scotts spreader, which provides even distribution - just make sure to apply when the lawn is wet and daytime temperatures are consistently between 60 and 90 degrees F. You can treat up to twice per year, so for most lawns, one bag will last the season.

In terms of build quality, the granular form is easy to handle and store, and the bag dimensions (16.3 x 10.8 x 3 inches) are manageable. The product weight is listed as 0.5 pounds in the specifications, but this seems to be a data discrepancy - the actual product weight is 11.32 pounds as shown in the title. This is likely a label error, and the bag is indeed substantial. It's important to follow the label instructions carefully to avoid harming non-target grass types or over-applying during hot weather.

One drawback is that this product is not suitable for all grass types, especially St. Augustine, which is common in warm climates. Also, the application window (wet lawn, specific temperature range) can be tricky if you have unpredictable weather. Some users might wish for more than two applications per year, but the product's efficacy makes this less of an issue for maintenance.

Overall, the Scotts Turf Builder Weed and Feed5 is a reliable, all-in-one solution for weed control and lawn feeding. It delivers on its promises for the grass types it supports, and the convenience factor is high. If your lawn is compatible and you follow the instructions, this product can save you time and keep your yard looking healthy and weed-free. For most homeowners, it's a solid choice.

Scotts WeedEx Prevent with Halts is a pre-emergent herbicide designed to stop crabgrass and other listed weeds before they get a chance to sprout. It's a granular product you spread over your lawn using a standard spreader, making it a straightforward addition to your spring or fall lawn care routine. This product is best for homeowners who want to take a proactive approach to weed control, especially if crabgrass has been a recurring problem.

The standout feature is its ability to prevent a wide range of weeds, including foxtail, spurge, barnyardgrass, and more, all season long when applied in early spring. For fall applications, it targets Poa annua, henbit, corn speedwell, and chickweed. The formula is rainproof after application, so you don't have to worry about a sudden shower washing it away. It also works through snow and freezing temperatures, giving you flexibility in timing.

The bag itself is straightforward - just a 10.06 lb plastic bag with clear instructions. The granules are fine and spread evenly with a rotary or drop spreader. Coverage is generous: one bag treats up to 5,000 sq ft. The product is safe for all common grass types, including Bermuda, fescue, ryegrass, and zoysia, but you should avoid using it on Dichondra or Bentgrass lawns.

One honest drawback is that this is strictly a preventative product. If you already have weeds growing, WeedEx won't kill them - you'll need a post-emergent herbicide for that. Also, timing is critical. Apply too early or too late, and you might not get full-season control. The product's rating of 4.6 out of 5 suggests most users are satisfied, though there are no written reviews yet to provide specific feedback.

Overall, Scotts WeedEx Prevent with Halts is a reliable, easy-to-use pre-emergent that delivers on its promises. It's a solid choice for anyone looking to get ahead of lawn weeds without dealing with messy sprays or complicated mixing. For best results, follow the label instructions carefully and pair it with a good lawn care schedule.
