7 Best Weed and Feed Reviews – Give Your Lawn A Professional Look The Easy Way
When your lawn falls short of your expectations despite all the hard work you put into it, don’t blame yourself. It’s not you, it’s the lawn. Luckily, lawn problems, no matter how serious, are usually easy to fix with the right tools. This is not about working harder, but working smarter.
From weeds to yellow spots and barren patches, lawn problems can be a real headache. Not only does a meticulous lawn enhance your curb appeal, but it also gives you bragging rights in the neighborhood.
But as we all know, it’s not easy to keep your lawn looking its best every day all year round. The grass looks pale and sickly. Clumps of weed are sprouting everywhere, and heavy foot traffic has all but flattened the turfgrass. It looks like you’re in need of a double-action product that kills the weeds while feeding the grass at the same time.
Weed and Feed products do just that. They eliminate various types of weeds from your lawn and offer your grass the nutrients they need. Here we review the top weed and feed products in the market detailing their advantages and drawbacks. We follow that with a comprehensive buying guide to help you choose the right product for your specific lawn needs.
Best Weed and Feed Reviews
Whether your lawn has bare spots, yellow grass, or a weed infestation, the following weed and feed fertilizers offer answers to your lawn problems. You’ll be able to weed-proof your lawn while feeding your turfgrass with minimal effort.
1. GreenView Fairway Formula Fertilizer (Editor’s Choice)
We start off with the best of the pack. If you don’t have either the time or patience to keep the weeds on your lawn in check and take care of the feeding of the grass, then GreenView Fairway Formula Fertilizer might be what you’re looking for. This pro-grade fertilizer makes it easy to achieve a professional lawn appearance without putting in too much work.
What makes this fertilizer and weed-killer combo stand out is the wide range of weeds it targets. It focuses specifically on difficult lawn weeds such as crabgrass. Not only does it kill this lawn bane, but it blocks it from returning. People who had to struggle with crabgrass in the past know how stubborn this weed is and how it often comes back the next spring. So it’s a plus point for this product with its proprietary formula that it keeps crabgrass from invading your lawn after applying it.
Not only does GreenView eliminate crabgrass but it’s also effective against over 200 other weeds including the pesky dandelions. But that’s only half the story. Since we’re talking about weed and feed fertilizers, then the feeding part is just as important as killing and blocking weeds.
Greenview uses a 65 percent slow-release formula that’s high on nitrogen to feed the grass for up to 12 weeks after each application. The 24-0-6 formula is suitable for many turfgrass varieties as long as the roots are established in the soil.
On the downside, you need to watch out for young grass on the lawn. The high concentration of nitrogen in the fertilizer could burn the tender roots of yet-to-establish turfgrass. If you have grass varieties that are sensitive to nitrogen such as Saint Augustine or dichondra grass, you shouldn’t use this fertilizer.
- Blocks crabgrass.
- Effective against 200 weeds.
- Proprietary 65 percent slow-release formula.
- Covers 5,000 square feet.
- Not suitable for sensitive turfgrass.
- Needs heavier application to fight off clovers.
2. Scotts Liquid Turf Builder (Best Value)
Let’s face it. The main reason you’re using a weed and feed fertilizer is that you don’t have time to deal with weed infestation while also feeding the grass. I get it. It’s a lot of work. So when a product like Scotts Liquid Turf Builder comes in a nifty easy-to-use bottle with a hose, you know you’re in for a treat. All you have to do is point the nozzle and spray the liquid. It doesn’t get any easier than that.
This product kills a wide range of weeds that attack lawns both in the northern and southern parts of the country. This list includes pigweed, buckhorn, ragweed, chickweed, ground ivy, plantain, henbit, spurge, knotweed, oxalis, lambsquarters, and poison ivy. It also does a good job taking care of dandelions and clover.
As a post-emergent pesticide, Liquid Turf Builder is more efficient against weeds already growing on your lawn. It doesn’t prevent them from starting or stop them from coming back. So you’ll need to use it whenever you see weeds emerging among the turfgrass. The sooner you apply it the better results you get. With some stubborn weeds, especially clover, you might need to use another application about 3 weeks after the first one.
The container covers an area of about 6,000 square feet giving you the best value for your money. It has a custom 25-0-2 formula with a high concentration of nitrogen, zero phosphorus, and trace amounts of potassium.
Using this product is both safe and convenient. However, it has a major downside. It doesn’t work against crabgrass, either in pre-emergent or post-emergent capacities. That’s a major disadvantage and if you have crabgrass on your lawn, you’ll have to look for another product on this list.
- Covers 6,000 square feet.
- Effective against growing broadleaf weeds.
- Good value for money.
- Doesn’t kill crabgrass.
- Doesn’t work as a pre-emergent pesticide.
3. Bioadvanced All in One
We all know how tough it is to get rid of crabgrass. I’m not just talking about keeping it off the lawn, but actually killing the growing weed after it has taken root. So one of the criteria that separate a top-notch weed and feed fertilizer from the rest of the pack is its ability to attack crabgrass after emerging and eliminating it. In that respect, Bioadvanced All in One delivers in spades.
After it takes care of crabgrass, it turns to dandelions, chickweed, clover, spotted spurge. It shows satisfying results eliminating a long list of over 200 types of weeds. So you can use it as a post-emergent pesticide. However, it doesn’t block crabgrass from returning to the lawn. You’ll need to apply it whenever you spot emerging weeds.
In addition to its weed killing qualities, Bioadvanced uses a proprietary technology called micro-feed action that unlocked nutrients in the soil while also improving nutrient uptake.
This product is suitable for Northern turfgrass including, Fescue, Seashore Paspalum, Zoysia grass, Buffalo grass, Kentucky Bluegrass, and Ryegrass. The package protects and feeds about 5,000 square feet.
On the downside, you cannot use this product with other types of turfgrass. Also, when applied to Bermudagrass, you might notice the grass turning yellow. It will take up to a week for the grass to regain its lush green color.
- Kill crabgrass after emerging.
- Effective against 200 types of weed.
- Easy to spread and use.
- Micro-feed action.
- Causes Bermudagrass discoloration.
- Limited to only Northern turfgrass.
4. Scotts Turf Builder Southern Triple Action
Scotts is an established brand in the world of weed killers and fertilizers. So when the Scotts Turf Builder Southern Triple Action package arrived at my door, I already had high expectations for it. And I have to say I wasn’t disappointed. The Triple Action delivered on all three fronts as advertised. I had a tough time keeping dollar weeds and oxalis off my lawn but one application in the early spring of this weed and feed was enough to eliminate these stubborn weeds. I still applied it again later that spring just to be on the safe side.
With a decent coverage rate of 4,000 square feet, this product is safe to use with many Southern turfgrass varieties. It works well on Zoysia grass, carpet grass, centipede grass, and Saint Augustine grass.
On the downside, you can only apply it in the spring with temperature in the mid-seventies. The formula doesn’t work in cold temperatures. Also, it’s not safe to apply it on newly mowed grass or tender grass that hasn’t established in the soil yet. After spraying, you should keep pets and children away from the lawn for at least one day until the pesticide has dissipated.
Although it works well as a pre-emergent pesticide, Scotts will not have much success against crabgrass once it takes root in the lawn. That’s the main drawback that kept it from contending for the top place on this list.
- Works well against growing broadleaf weeds.
- Suitable for Southern turfgrass.
- Covers 4,000 square feet.
- Not safe to use on newly seeded areas.
- Doesn’t kill growing crabgrass.
5. Pennington UltraGreen
As we have seen so far, some weed and feed fertilizers work only on northern grass while others specialize in Southern turfgrass varieties. But what if you want to use a product that works on all types of turfgrass? Pennington UltraGreen is that kind of product that handles a wide variety of weeds as well as grass types.
Its ability to aggressively go after over 250 types of weeds is impressive. You can use it against anything from dandelions and dollar weed to henbits, plantain, chickweed, and white clover. The conveniently resealable package offers protection to an area of 5,000 square feet.
One thing to watch out for with the UltraGreen is its high concentration of nitrogen. With a 10.5 percent slow-release nitrogen in a 30-0-4 formula, it has the highest nitrogen ratio among the products on this list. So use it with caution on sensitive turfgrass and make sure the roots are well established in the soil before you apply the fertilizer. It could burn tender shoots of grass and sensitive roots.
Another drawback about this product is that you can only use it in the late spring when the temperature is between 60 degrees to 80 degrees Fahrenheit. Also, it doesn’t work against crabgrass.
And while it advertises its suitability for Northern as well as Southern turfgrass, you should not use this product with Saint Augustine grass. The extra nitrogen in the ingredients would burn the grass or at least stunt its growth.
- Suitable for Northern and Southern turfgrass varieties.
- Covers 5,000 square feet.
- Effective against 250 types of broadleaf weed.
- Not good against crabgrass.
- Not suitable for Saint Augustine grass.
6. Preen 2164169 One LawnCare
While using weed and feed fertilizers, you need to be wary of the timing of the applications. Not only are you targeting pesky weeds, but you’re also feeding the grass with every application. In other words, you can’t just use it any time of the year since you might trigger growth in dormant grass in the fall or winter which has devastating consequences. But with Preen 2164169, you don’t have to worry about that.
Preen is safe to use three out of four seasons. You can use it in the spring, summer, and fall. Furthermore, you can use it to fight off fully grown crabgrass. This is what makes Preen stand out among other weed and feeds. It is still effective against crabgrass that’s about 4 weeks old. So you can use it as both a pre-emergent and a post-emergent weed killer.
But it’s not just crabgrass and dandelions. Preen shows satisfying results eliminating more than 250 types of broadleaf weeds on the lawn. This includes white clover, a notoriously difficult weed to manage once it takes root on your lawn.
The slow-release formula allows this fertilizer to keep feeding your grass for up to 8 weeks after each application. It has a custom 24-0-6 formula with zero phosphorus and covers over 5,000 square feet of lawn offering both nutrition and protection.
That said, you shouldn’t use this product if you have carpet grass, colonial bentgrass, Saint Augustine grass, or dichondra. The high concentrations of nitrogen could cause injury to the turfgrass.
- Can be used any time of the year except in winter.
- Eliminates crabgrass 4 weeks after emergence.
- Zero phosphorus formula.
- Effective against 250 types of weed.
- A little pricey.
- Requires more than one application to get rid of clover.
7. Jonathan Green Green-Up
A newcomer to the world of weed and feed, Jonathan Green Green-Up is already getting the attention of gardeners and homeowners. Its claim to fame is its focus on crabgrass. Not only does it aggressively eliminate growing crabgrass, but it also blocks it from returning to the lawn. So it works well both as a pre-emergence and a post-emergence herbicide.
Helping Green-Up perform is a new proprietary technology called dimension Crabgrass control. It targets crabgrass in the lawn and effectively kills the invasive weed without affecting the turfgrass or other vegetation in its vicinity. You can use this product on crabgrass already growing.
This is something that sets it apart from other weed and feeds on this list. Usually, after crabgrass has reached a certain maturity, weed killers become less effective. But Green-Up can be used on crabgrass 4 weeks later than other pesticides. Applying it isn’t limited to spring the way it is with other brands. You can use it all season without having undesirable side effects on the soil or the turfgrass.
Along with crabgrass, this weed killer also eliminates other broadleaf weeds including spurge, bittercress, henbit, and chickweed among others. The package covers 5,000 square feet of the lawn both protecting and feeding in the turfgrass. And on the feeding side, the new formula has 25 percent slow-release nitrogen, doesn’t have any phosphorus, and is non-staining.
On the downside, you’ll have to wait for 4 months after applying the weed killer before you can seed the lawn. This limits your options when choosing the right time to apply the weedkiller.
- Targets crabgrass before and after emergence.
- Eliminates crabgrass 4 weeks later than other similar products.
- Protects and feeds 5,000 square feet.
- Need to wait 4 months after application to seed the lawn.
Weed and Feed Buying Guide
After this comprehensive review of the most popular weed and feed fertilizers in the market, let’s take a look at common lawn problems, the different types of fertilizers, and the best times to fertilize your lawn and apply weed and feed products.
Common Lawn Problems
Crabgrass and invasive weeds are not the only problems you might have to deal with on your lawn. Even a well-maintained lawn is prone to yellowing problems due to compact soil, poor soil, inadequate watering, excessive heat in the summer, or frost in the fall and winter.
Pests might also attack your turfgrass. White grubs, billbugs, and cranberry girdlers are common pests that feed on the grass and weaken its root system, creating yellow spots all over the lawn. You can use GreenView to tackle most of these problems including weak or mal-nourished grass.
Another problem you have to watch out for is fungi. Necrotic ring fungus is a hard infection to treat. It creates yellow rings in the lawn that can stay for three years. You’ll often have to turn up the soil, uproot the infected grass, and reseed the lawn.
Spilled chemicals can have a devastating impact on the soil and the quality of the grass as well. Whether it’s gasoline from your vehicle or pet urine, the roots of the grass are no match to the high concentrations of ammonia and gasoline in the soil. To solve this problem you’ll have to dig up the contaminated soil, supply fresh soil, and reseed the bare patches.
Check the Soil
Before you seed your lawn, you should take the necessary steps to test the soil to make sure the turfgrass you chose will actually grow on the lawn. Soil testing not only measures the presence of different nutrients in the soil but also the pH levels. To start with you need to make sure there’s a good balance of the three main nutrients, nitrogen, potassium, and phosphorus in the soil. Grass often needs more nitrogen than potassium and it just requires trace amounts of phosphorus in the soil.
You can use a pH meter to check the acidity levels of the soil and add coarse sand or perlite to adjust these levels.
On top of that, you need to test the soil’s texture and drainage. Almost all types of turfgrass need a well-drained and loamy soil. Loamy soil has more silt and sand than clay which improves its drainage. To check that your soil has the right texture, fill the palm of your hand with soil and close your hand tightly. If the soil turns into a clump in your hand then it needs more perlite and sand.
Check the soil drainage in your lawn by digging a hole a few inches deep. Fill the hole with water and see how fast the water disappears. If it takes a long time for the soil to absorb the water, then your lawn is not well-drained. Fix that problem by adding organic material and coarse sand.
Types of Weed and Feed
When selecting the best weed and feed fertilizer for your lawn, you often have to make a choice between the two main types, liquid or granular. Each has its advantages and drawbacks.
- Liquid: You will often use liquid weed and feed if you have a small lawn or backyard. It is often easier and more convenient to apply than granular products. The container often has concentrated liquid and you’ll need to connect it to your garden hose and start spraying. The whole process can take no more than a half-hour to cover your lawn. Some products such as Scotts Liquid Turf Builder have a lower risk of burning the grass since you can adjust the water flow as well as the concentration of the fertilizer according to your needs.
- Granular: If you have a large lawn, then granular weed and feeds are a better option. You load the spreader with the fertilizer and criss-cross the lawn until you’re done. There’s less risk of spillage or stains with granular fertilizers. GreenView is an excellent example of this type. It doesn’t require diluting or mixing with water which makes it less messy. This is the recommended type for lawns larger than a quarter acre but less than one acre.
Best Times to Fertilize the Lawn
When it comes to fertilizing your lawn, timing is of the essence. While some weed and feeds are limited to the early spring in warm climates and late spring in cold ones, other products can be applied all season without time limitations. In general, you should wait for the air temperature to go above 55 degrees Fahrenheit before you apply the fertilizer.
Ideally, from mid-April onwards is the right time to fertilize your lawn for most parts of the United States. Always pick a warm day and avoid applying weed and feed on rainy days or during strong winds. This could blow away the granules of fertilizer or steer them to where you least want them.
After the first application in mid-April, you’ll need to follow up with another in Mid-may. Depending on the soil quality you will need to apply the weed and feed between six to eight weeks throughout the summer and mid-fall. If you notice weeds emerging in your lawn between applications, you can use the weed and feed in a more focused fashion on the infected areas.
Between October and April, you should hold back the fertilizer. Dormant grass doesn’t need fertilizing since it could trigger new growth during the cold winter.
Weed and Feed FAQs
If you’re new to using weed and feed, you might still have some unanswered questions. Here we answer the most common questions.
How does Weed and Feed work?
The way weed and feed products approach killing weed depends on the type of weed these products target. Generally speaking, there are two types of weeds that attack your lawn. The first is broadleaf weeds such as clover, dandelions, ground ivy, and others. Weed and feed brands such as Scotts and Preen would often attach the herbicide to the leaves and roots of the weeds in the first phase of the process.
The second type of weed is crabgrass which is very common and harder to get rid of. Weed and feed brands such as BioAdvanced and GreenView do a good job of eliminating this stubborn weed. Usually, they add a second phase that targets narrow leaf weeds. You might need to use more than one application to fully remove crabgrass and other narrow-leaf weeds from your lawn.
The final phase of the weed and feed process is the feeding part. While the product is killing the weed, your grass also gets valuable nutrients and plant food supplements that give the lawn a lush green look. Most products are high in nitrogen and low in potassium with zero content of phosphorus. That’s the right nutrient formula that your grass needs. However since some products have a higher concentration of nitrogen than others, you need to read the instructions carefully to apply the fertilizer in the right dosage.
How do I apply Weed and Feed?
Since there are two types of weed and feed, how you apply the fertilizer depends on the type you choose. Granular types such as BioAdvance and GreenView would usually require you to use a spreader. This helps you spread the fertilizer evenly across the lawn and prevent damage to the turfgrass. Even if you have a small lawn, resist the temptation to use your hands to spread the material. Many good lawns were ruined when clumps of fertilizer landed on certain spots while other areas remained untouched.
If your lawn is too small (less than a quarter acre) for a spreader, you might opt for a liquid weed and feed such as Scotts Liquid Turf Builder. It’s easy to use and only requires you to connect the container to a garden hose. Turn on the water and aim the nozzle at the lawn. When you’re done, release the handle and turn off the water. This is usually the easiest way to apply this type of liquid fertilizer.
There are other liquid products that require a more elaborate way of mixing the concentrated material with water before you can apply. We didn’t review these products since they’re a lot of hassle and can be messy to mix and apply.
How many Weed and Feed applications do I need?
The number of applications of weed and feed on your lawn depends on the type of turfgrass you have and the weed infestation. But in general, the first application in early or late spring (depending on the climate) is a good starter to nourish the grass at the beginning of the growing cycle. This early application also takes care of the sprouting weeds that could take advantage of the warming temperatures and the rainfall to spread across the lawn.
In most cases, you’ll need to apply weed and feed at least once every two months between April and October every year. If you need to fight emerging weeds between applications, then aim for a concentrated application that targets only the infested areas in the lawn.
The Last Word
We have taken a whirlwind tour of the most popular weed and feed products available online. We covered the good points and drawbacks of each product then detailed the main features to look for when buying a weed and feed fertilizer for your lawn.
After this exhaustive guide of weed and feed fertilizers, we recommend GreenView Fairway Formula Fertilizer. As both a pre-emergent and post-emergent herbicide, It does a good job eliminating crabgrass from your lawn and blocking it from coming back. The granular type product doesn’t stain and is easy to apply using a spreader. The package covers 5,000 square feet which is more than enough for most average-sized lawns. The product has a 65 percent slow-release formula that will feed the grass for weeks after each application.
If you’re on a budget, we recommend Scotts Liquid Turf Builder. The liquid fertilizer is easy to use and gives you a bang for your buck. The post-emergent herbicide works effectively against a wide variety of broadleaf weeds. It has an affordable price and one container protects and feeds about 6,000 square feet of the lawn.

Weeds can be tough to contain. And if you can’t stand the thought of spending another hour tirelessly weeding your yard, it may be time to snag a store-bought weed killer. “If left unchecked, weeds can completely ruin a lawn,” says Gladys M-Curtis, Ph.D., plant scientist, who adds that these herbicides are “one of the faster options in weed control.”
To determine the best weed killers, we researched dozens of the most popular options, considering their active ingredients, effectiveness, and ease of use. We also paid attention to whether the products were designed to kill weeds, prevent weeds, or both.

The first thing you should do before shopping for a weed killer is identify the types of weeds you have growing in your yard. Then, you can “determine your goal and use the information to select a weed killer,” says Dr. M-Curtis.
Our top pick, Scotts Turf Builder Triple Action, is a best-in-class option, thanks to its ability to kill and prevent specific weeds while fertilizing grass on your lawn.

Best Overall Weed Killer: Scotts Turf Builder Triple Action
Who it’s for: People who want a weed killer that also acts as a fertilizer.
Who it isn’t for: People who want to kill weeds on flower beds or vegetable gardens.
Scotts Turf Builder Triple Action earned the top spot on our list because it does more than the average weed killer. This product kills pesky lawn weeds and prevents unwanted grassy weeds from growing. And it does both of these things while fertilizing your lawn at the same time, eliminating the need for a separate fertilizer. This three-in-one approach sets it apart from other popular weed killers and preventers, making it a particularly convenient way to clean up your lawn. Although it’s important to note that this weed killer is intended for lawn care, not flower beds or gardens.
Since this is a selective weed killer, you don’t have to be precise when applying it. Instead, you can spread it across your lawn and trust it to kill specific weeds while preserving the grass you want. When used correctly, the so-called “weed and feed” will kill common weeds like dandelions, clover, chickweed, and more. It can also prevent grassy weeds, like crabgrass, from growing for up to four months (although it will not kill any existing crabgrass).
- Active Ingredients: Dicamba, pendimethalin, and 2,4-D
- Pre-Emergent: Yes
- Post-Emergent: Yes
- Selective: Yes
- Targeted Plants: Dandelion, clover, dollarweed, ground ivy, chickweed, henbit, plantain, English daisy, crabgrass, barnyard grass, fall panicum, foxtail, and annual bluegrass
- Application Style: Broadcast spreader (sold separately)
Best Natural Weed Killer: Green Gobbler 20% Vinegar Weed and Grass Killer
Who it’s for: People who want a weed killer that’s safe for use around pets and children.
Who it isn’t for: People who want a selective weed killer that doesn’t require precise application.
Green Gobbler’s weed killer is an all-natural way to prevent weeds from growing in your yard. Its formula contains two simple ingredients: vinegar and water. But since the mixture is so concentrated, you can expect the weed killer to be about four times stronger than the table vinegar in your pantry.
This treatment works by drying out the weeds it touches, a process that typically kills them within 24 hours. This makes it an extremely effective natural weed killer. But there’s one important thing to note: The Green Gobbler weed killer will prevent all kinds of seeds from growing roots—including any seeds you intentionally planted if you accidentally spray them. (After all, vinegar doesn’t know the difference between weeds and vegetables.) This makes the application process less convenient than the selective weed killers on this list. But if your top priority is using all-natural ingredients, this is a necessary tradeoff—the product is one of the few all-natural and organic weed killers out there. And since it comes inside a tank sprayer, it should be easy to target unwanted weeds while avoiding the plants you want to keep. Plus, it’s safe to use around children and pets when used as directed, unlike most chemical weed killers.
- Active Ingredients: Vinegar
- Pre-Emergent: No
- Post-Emergent: Yes
- Selective: No
- Targeted Plants: All
- Application Style: Tank sprayer
Best Weed Killer for Lawns: BioAdvanced All-in-One Lawn Weed Killer Concentrate
Who it’s for: People who want to kill weeds on large lawns both before and after they’ve emerged.
Who it isn’t for: People who want a weed killer that’s safe to use around pets and kids.
Weeding by hand can be frustrating. But spraying individual weeds with weed killer can be just as tedious, especially if your yard is big. So when you’re working with a large space, like a lawn, a selective weed killer comes in handy. And that’s why we recommend BioAdvanced’s All-in-One Lawn Weed Killer for the job.
The weed killer is designed to kill 217 common yard weeds before and after they’ve emerged, including crabgrass. It’s a great option for killing fully grown weeds and for stopping younger weeds in their tracks. This dual approach makes the BioAdvanced weed killer a great pick for your lawn, and its easy application method makes it an even better buy. Simply attach it to your garden hose and turn the water on, then use your thumb to activate the sprayer. Since the weed killer is selective, you can spread it freely across your yard to clean up weeds without harming your lawn.
- Active Ingredients: 2,4-D, dimethylamine salt, Quinclorac, and dicamba
- Pre-Emergent: Yes
- Post-Emergent: Yes
- Selective: Yes
- Targeted Plants: Dandelion, clover, thistle, chickweed, crabgrass, and more
- Application Style: Tank sprayer
Best Weed Killer for Flower Beds: Roundup Landscape Weed Preventer
Who it’s for: People who want to protect landscaped flower beds from growing new weeds.
Who it isn’t for: People tending to lawns or vegetable gardens, or anyone who primarily needs to get rid of existing weeds.
Hoping to keep weeds out of your flower beds? Roundup’s Landscape Weed Preventer is a great first line of defense. While this product won’t get rid of existing weeds, it will kill weeds before they can grow in the first place, making your flower beds much easier to maintain in the long run.
The treatment contains pendimethalin as its active ingredient, and it acts as a “weed barrier,” so it stops common weeds from growing wherever you sprinkle it. This makes it a great pick for people who have flower beds and intricate landscaping. You can spread the treatment around your plants and flowers, and it will keep weeds at bay for up to six months. The Roundup weed preventer is another option on this list that’s selective, so it shouldn’t harm your prized flower beds or landscaping, even if you’re a little imprecise when applying it. It also has a built-in applicator, which means you can shake out the treatment directly from the bag.
- Active Ingredients: Pendimethalin
- Pre-Emergent: Yes
- Post-Emergent: No
- Selective: Yes
- Targeted Plants: Clover, chickweed, crabgrass, foxtail, and more
- Application Style: Shaker bag
Best Weed Killer for Vegetable Gardens: Preen Natural Vegetable Garden Weed Preventer
Who it’s for: People who want to stop weeds from growing around vegetables and herbs.
Who it isn’t for: People who want to kill existing weeds in their yard or garden.
When controlling weeds in a vegetable garden, you want a weed killer that’s all-natural and safe for use around food and herbs—and Preen’s Natural Weed Preventer fits the bill. This weed killer contains a single ingredient—corn gluten meal—which prevents germinating weeds from growing roots. You’ll have to be proactive though: This product stops weeds from growing in the first place, but it won’t kill any of the existing weeds in your vegetable garden.
The Preen weed preventer is another all-natural product that isn’t selective, so you have to make sure you only apply it to areas with weeds. Otherwise, you might find that the treatment stops your veggies and herbs from growing, too. But, when used correctly, the product works for up to four weeks, so you only need to apply it every month or so. And if you maintain an organic vegetable garden, it’s available in an organic version, too.
- Active Ingredients: Corn gluten meal
- Pre-Emergent: Yes
- Post-Emergent: No
- Selective: No
- Targeted Plants: All
- Application Style: Shaker
Best Weed Killer for Patios: Spectracide Weed and Grass Killer With Extended Control Concentrate
Who it’s for: People who need to kill weeds on paved areas like patios or driveways.
Who it isn’t for: People who want to target specific plants and weeds.
Fast-acting, effective, and easy to use, Spectracide’s Extended Control Weed and Grass Killer is a great option for patios, sidewalks, driveways, and other paved areas. The product relies on several active ingredients to control weeds, and it’s a very effective formula. It can kill existing weeds in as little as three hours and it can prevent new weeds from growing for up to five months. And you don’t have to worry about inclement weather right after application—if it rains more than 15 minutes after application, the precipitation won’t wash away the treatment.
Since this Spectracide weed killer isn’t selective, it should effectively knock out any plant or weed it touches. This may sound like a negative—if the product isn’t selective, you usually have to be careful where you spray it—but remember that you’re applying it on pavement. Anything growing out of your patio or driveway likely wasn’t supposed to be there in the first place. That’s why we still think using the Spectracide weed killer is an efficient way to clean up paved areas.
- Active Ingredients: Diquat dibromide, fluazifop-p-butyl, dicamba, dimethylamine salt, and oxyfluorfen
- Pre-Emergent: Yes
- Post-Emergent: Yes
- Selective: No
- Targeted Plants: All
- Application Style: Tank sprayer
Capable of killing existing weeds, preventing new weeds, and fertilizing your lawn, Scotts Turf Builder Triple Action is our favorite because it’s a triple threat. We also like that the treatment is selective, so you don’t have to worry about it harming your plants or grass while it cleans up the weeds in your yard.
How to Shop for Weed Killers Like a Pro
Weed killers can use a range of different ingredients—some natural, some not. If you’re curious about what’s inside a weed killer, be sure to check both its active ingredients list and its other ingredients list. We made it easy for you by listing the active ingredients for each weed killer we recommend (some common examples are dicamba, pendimethalin, vinegar, and 2,4-D). Unfortunately, most companies don’t disclose full lists of the other ingredients in their formulas, which makes it difficult to determine everything that’s in a given weed killer.
Pre-Emergent vs. Post-Emergent
Weed killers can be pre-emergent, post-emergent, or both. If a weed killer is pre-emergent, it will help you control weeds before they start to grow. (These are usually called weed preventers.) Post-emergent weed killers, on the other hand, will help you kill existing weeds in your yard. Finally, if the weed killer is pre-emergent and post-emergent, it will do both of these jobs.
Selective vs. Non-Selective
Some weed killers are selective, meaning they’re designed to kill certain weeds without harming other plants. Others are non-selective, so they’ll kill any plant they encounter. Selective weed killers are generally more convenient than non-selective weed killers: You don’t have to be super precise when applying them, and they won’t harm other vegetation such as landscape flowers or plants. But they’re also engineered, so people who want an all-natural solution should pick a non-selective weed killer instead.
If you choose to use a selective weed killer, check to see which weeds the product is designed to target. (You can usually find a list on the product label.) Make sure the formula you’re considering can help kill or prevent the specific weeds that you have in your yard. You’ll also want to confirm that it won’t kill grass on your lawn and any plants you want to keep.
There are many different ways to apply weed killer to your lawn and garden. Some of the most popular methods include traditional spray bottles, shaker bags, tank sprayers, and broadcast spreaders.
Generally speaking, targeted options (like traditional spray bottles) are more precise but not as convenient to use. You can easily treat weeds with a spray bottle, but it may take a while to get through your entire yard. This makes weed killers with targeted application styles a great option as long as it’s a non-selective formula.
Less targeted application styles (like broadcast spreaders) make it harder to be precise, but they’re easier to use. You can cover a lot of ground quickly, but you may end up spraying everything in your yard. Because there’s a greater risk of accidentally treating flowers or plants that you want to keep, these application styles are much better when you’re using a selective weed killer.
Questions You Might Ask
How do weed killers work?
There are two different kinds of weed killers—contact weed killers and systemic weed killers—and both work by disrupting the normal growth of a plant. “When sprayed on a weed, [contact weed killers] cause the membranes of the tissues…to be disrupted and the contents of the cells to leak,” Dr. M-Curtis says. This can cause the plant to turn brown, dry out, and eventually die—but it may not kill the plant down to its roots.
Systemic weed killers work a bit differently. According to Dr. M-Curtis, systemic options enter the tissues of the targeted weed and move around until they find “active” parts. There, the weed killer “can act by inhibiting the biological process of cell division, photosynthesis, or amino acid production,” she says. This means that systemic weed killers tend to affect entire plants, killing them down to their roots.
Can you mix different weed killers together?
Every expert we spoke to cautioned against mixing different weed killers. “If you mix weed killers together incorrectly, it can cause phytotoxicity, essentially burning your grass,” Augaitis says. “You may eliminate the weeds but damage your grass and garden while doing so.”
Do weed killers go bad?
Yes, weed killers can go bad. And once they have expired, they may not be as effective as they used to be. Even though weed killers can go bad over time, the “consequences can be minimal,” says Augaitis. If you decide to use an expired weed killer, there’s no way of knowing if it will actually kill your weeds. Augaitis says the product might simply not perform well anymore, which could still leave you with unwanted plants in your yard after treatment.

Are you looking to improve your lawn and kill the weeds? A Weed and Feed is the best way – Read our reviews to find the best product to suit you.
Taking the best care of your lawn means that you need to weed frequently, and fertilize at the right times of the year. Unfortunately, weeding your garden can be a time-consuming exercise, especially if you have a big piece of property.
Getting down on your hands and knees to pull weeds is back-breaking work. There’s also a chance that you don’t get the whole weed.

The Best Weed & Feed Reviews
We reviewed the best weed and feed products available. We went through dozens of products to isolate these five options. Choose a product that meets the needs of your garden, and say goodbye to the weeds while you welcome in the grass!
Best Pick: GreenView Fairway Formula Fertilizer
We start our review with the best product in its class. TheGreenview Fairway Formula Fertilizer Plus Crabgrass Preventer is the top choice in this review. We think of this as a professional grade-product, with long-lasting effects from the slow-releasing formula. In warmer climates, you can get away with two annual feedings in the early spring and fall, with no intra-seasonal feeding necessary.
When you think about the effect of this slow-releasing compound on reducing your annual feeding costs, it’s easy to justify the price tag for this product. The manufacturer states this formulation kills over 200-species of weeds, including chickweed, seedling crabgrass, and dandelion.
Due to the slow-releasing formula, this product is best for use on established lawns that have a healthy root system. Using it on younger grass may result in burning and stunted growth. The manufacturer has this weed and feed formula available in 18 and 36-pound bags. An 18-pound bag will cover 5,000-square feet of lawn.
- Short reaction time, with results noticeable after 4-weeks.
- Fertilizer requires infrequent application.
- Successfully eliminates dandelions.
- Might injure carpet grass, dichondra, and Saint Augustine grass.
Runner-Up Pick: Preen One Lawncare
This product is a close runner up on the GreenView Fairway formula. This weed and feed product is best for lawns where weeds are already growing and taking over the yard. This formula features post-emergent, so the user can apply it up to 30-days after noticing the first signs of crabgrass.
The manufacturer also states that this product kills white clover, dandelion, and over 250-species of broadleaf weeds. The weedkiller penetrates to the roots, destroying the weed while leaving your lawn weed-free.
Do not use this formula on carpet grass, colonial bentgrass, Saint Augustine or dichondra. Avoid using this fertilizer after sowing seeds for at least the first 8-weeks. The Preen One Lawncare formula is ideal for use on Zoysia, bluegrass, Fescue, or ryegrass. The 36-pound bag is more than enough to cover 10,000-square feet of lawn. You also have the option of 18-lbs and 9-lbs bags as well.
- Effective in removing dandelions.
- Works in less than 4-weeks.
- Grass looks healthier and thicker after use.
- May require several applications.
Budget Pick: GreenView Weed and Feed Review
The smaller brother of the Fairway formula from the same company is still a potent weed and feed product for the home garden. The formula comes with the same 250-species weed killer formula featured in the Fairway blend, and the same time-release formula to save you on seasonal feedings.
Greenway specialized this formula for generalized use country-wide, with select ingredients that every lawn needs for optimal nutrition and growth. It’s slightly less potent that the Fairway blend, and you’ll need to reapply every eight to 190-weeks for best results.
Apply it to your lawn straight after mowing, and let it help your grass retain water and nutrients in the soil. This formula comes in 9-lbs, 18-lbs, and 36-lbs bags, for coverage of up to 15,000-square feet.
- Kills dandelions fast before they spread.
- It gives the grass a dark green color.
- It prevents the spread of invasive weeds.
- It improves the thickness and growth of grass.
- Takes multiple applications to kill weeds.
- Clovers are resistant to this product.
Scotts Turf Builder
While it’s not in the top three products in this review, Scotts Turf Builder Starter Food and Weed Preventer is a premium lawn care formula that you should still consider. This product contains lawn food and pre-emergent, with active ingredient lasting up to 6-weeks between feeding sessions.
The product is effective at removing dandelions, crabgrass, and weeds from the lawn, but you need to apply it more frequently than the Greenview products. As a result, you’ll end up spending as much on this product as the Fairway formula from Greenview.
However, Scott’s turf builder stops weeds from sprouting. As with most other pre-emergent herbicide formulas, you’ll need to apply it in the early spring. This strategy prevents the weeds from growing when the ground starts to get warmer, and the rains arrive.
This product is also suitable for use with sod and grass plugs and sod, and the formula helps new lawns thrive, making it the ideal choice for younger grass. One 9-lbs bag covers 5,000-square feet.
Take a look here we go into more detail about Scott’s Fertilizer products.
- Use this formula to reseed a garden or start a new one.
- Works fast, results in 2-weeks or less.
- Grass proliferates and turns thick with a deep green color.
- Not available in Florida

Weed and Feed Buyer’s Guide
Fertilizer and weed killer are essential parts of any gardeners toolshed. Fertilizer improves the health of your plants, causing them to yield and flower more than without using the treatment. It’s the same for your lawn as well. By feeding your garden, you ensure that your grass grows thick, healthy, and full of color.
If you’ve never had to deal with fertilizer before, then out buyers’ guide will give you everything you need to know about this topic.
Looking for Lawn Deficiencies
Anyone that’s new to garden needs to learn about the importance of adding nutrients to your lawn. Nutrients increase your lawn’s ability to process water and sunlight, giving them a healthy root structure that avoids diseases and premature death of the grass. When your garden starts to develop deficiencies in nutrients, it will turn up in patches of discolored lawn. By treating it with fertilizer, you restore these burned or spare patches to normal health.
Fertilizer complex’s come in a range of blends using three to four different minerals. The most common types found in fertilizer are phosphorous, nitrogen, and potassium. Nitrogen is the mineral responsible for promoting growth in your grass, and giving it that deep green color every gardener loves.
Phosphorous helps to stimulate root growth, and potassium helps your lawn with drought and disease resistance. Most fertilizers have a combination of these three essential ingredients, along with some other additions to specialize in the formulation. Fertilizers can help your lawn deal with deficiencies in calcium, carbon, oxygen, carbon, boron, magnesium, boron, iron, cobalt, and manganese as well.
Fertilizer can get your lawn looking it’s absolute best.
Testing Your Soil
The first step in analyzing what fertilizer will suit the needs of your lawn is through a soil sample. You can take a sample of the soil of your lawn through to a nursery for testing. Most places will get your test results while you wait. After receiving the test, the technician will make recommendations on minerals you need to add to the soil.
Reading Fertilizer Labels
After receiving your test results, it’s time to pick the right fertilizer blend. Every bag of fertilizer will list the ration of nitrogen, phosphorous, and potassium on the label. Ask the technician who did your soil sample about the best ratio to suit the mineral deficiencies in your lawn.
The Different Types of Fertilizer
There are two common types of fertilizer on the market; liquid and granular. Both of these types have individual advantages and disadvantages. We recommend that you stick with the tried and tested granular types of fertilizer. Most companies that produce spray fertilizers make them for indoor use or small gardens, and granular offers better value for your money.
Some fertilizers feature slow-release formulas, and you don’t have to fertilize as often to achieve good results. However, most fertilizers require you to treat the lawn at least every 8-weeks from the start of spring.
How to Fertilize Your Lawn
After purchasing your fertilizer formula that’s ideal for restoring the health of your grass, it’s time to spread it on your lawn. We recommend that you use a fertilizer spreader. A spreader provides you with an even level of disbursement over the lawns surface.
A chest-mounted spreader would be the ideal option to fertilize a smaller lawn. You strap on the harness, fill the hopper, and walk around your yard winding a crank. Repeat this treatment every few weeks, and your lawn will be looking great in no time.
Types of Grass
Different species of grass respond better to different fertilizer formulations. If you don’t know what kind of grass you have growing in your yard, then take a sample along to your nursery when you go for the soil test. An experienced gardener will be able to tell you what kind of grass it is with a simple look at your sample.
There are general fertilizers that may burn sensitive species of grass. So, always ensure that you choose the right formulation before you go home and kill your entire lawn. We recommend a slow-release formula for established laws.
These formulations have strong doses for your grass that release over many months. We don’t recommend these formulations for younger lawns that are not yet mature. Younger grass may require a more frequent application to prevent burning from slow-release formulations.
The Best Weed and Feed Formula for Southern Lawns
Southern grass species prefer wetter conditions and plenty of fertilizer. You can use Scotts Triple Action for Southern Lawns to take care of your Bahia, Bermuda, St Augustine, and centipede varieties of grass.
The Best Weed and Feed Formula for Bermuda grass
BioAdvanced 3 in 1 Weed and Feed is the best option for your Bermuda grass. This species is common around Texas, and not all weed and feeds are suitable for these lawns.
Tips for Feeding Your Lawn
To get the best results out of feeding your lawn, you need to pay attention to your feeding schedule. Timing is of the utmost importance, and knowing when to spread your fertilizer is half the battle.
For older, established lawns, early springtime is the best time for the first feeding session of the season. If you use a slow-releasing formula, you won’t have to feed again until mid-May. After the May feeding, you’ll need to increase the fertilizer schedule to once every six weeks to accommodate the summer growth. Keep feeding your lawn through until the end of October.
Watering Your Lawn
When fertilizing your lawn, it’s essential that you remember to keep watering throughout the summer. If you don’t water your garden after feeding it, then you’ll probably end up causing burning in some patches. Water thoroughly after your feeding session to ensure that the nutrients go into the ground.
We recommend that you use a large sprinkler system to water your lawn after a feeding session. Always water in the early morning before the sun gets too high in the sky. The heat of the day increases evaporation rate, and watering later in the afternoon or peak sun hours will be wasting this resource.
Weedkiller in your Fertilizing Formula
All of the weed and feed formulas listed in this review come with weedkiller included. Dandelions are a pesky invasive species that turn up in everyone’s lawns in the summertime. If you don’t take extra precaution during the summer months, and weed out those pesky plants, they can take over a garden quickly.
Fortunately, all of the products in this review are effective at killing off dandelions that invade your lawn, before they have a chance to spread. Some of the formulations in this review can remove up to 250-species of weeds from your yard.
Dandelions are one type of nuisance weed that can be killed
