10 Best Fertilizer That Kills Weeds but Not Grass Options for a Weed-Free Lawn in 2026

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.

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.

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.

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 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.

The Roundup Weed & Grass Killer₄ with Pump 'N Go 2 Sprayer is a concentrated herbicide that comes in a 1.33-gallon container with a built-in sprayer. It's designed for homeowners who want to eliminate tough weeds quickly without having to mix or buy a separate sprayer. This product is ideal for anyone managing flower beds, trees, shrubs, patios, driveways, and other outdoor areas.

One standout feature is its rainproof guarantee in as fast as 30 minutes. After a light rain, you don't have to reapply. The formula also starts showing visible results in hours, which is faster than many competitors. It kills weeds to the root, including stubborn species like poison ivy, crabgrass, and dandelion. The ability to plant new ornamentals 1 to 30 days after application adds flexibility for gardeners.

The Pump 'N Go 2 sprayer is a real convenience. It delivers up to 10 minutes of continuous spray without pumping, and the extendable wand lets you target weeds without bending over. The sprayer is lightweight and easy to handle. However, because it's plastic, it may wear over time, and you'll need to rinse it thoroughly after use to keep it working well.

On the downside, there are no customer reviews yet for this specific version, so real-world feedback is missing. Also, this is a non-selective herbicide, so any accidental overspray on desired plants can cause damage. Users should apply on calm days and use protective gear like gloves and glasses.

Overall, the Roundup Weed & Grass Killer₄ with Pump 'N Go 2 Sprayer offers a convenient, all-in-one solution for weed control. It delivers fast results and the sprayer makes the job easier. If you need to tackle tough weeds in multiple areas around your home, this product is a solid choice. Just be careful where you spray and store the sprayer properly.

However, be careful with overspray on desirable plants or garden beds because this is a non-selective herbicide for lawns only.

Overall, the Spectracide Weed Stop For Lawns Plus Crabgrass Killer is a solid choice for homeowners wanting an effective, easy-to-use weed killer.

On the downside, this product is non-selective, meaning it will kill any plant it touches. If you accidentally spray a prized shrub or flower, it will likely die.

Overall, Natural Armor Weed and Grass Killer delivers on its promise: a powerful, no-glyphosate solution that works quickly and safely.
