A single product that at one application fertilizes your lawn and controls weeds helps you save time and energy when growing and maintaining a beautiful lawn. We reviewed eight varieties of these weed and feed products based on their ease of use, spreadability on your lawn, and their overall value.

Our top pick, Scotts Turf Builder Weed and Feed, stood out from the rest for its ability to extinguish the most notorious weeds, such as dandelions and clover, and its ease in fertilizing at the same time.

Here are our top picks for the best weed and feed products for a beautiful lawn.

Best Overall: Scotts Turf Builder Weed and Feed

Gets rid of hard-to-kill weeds such as dandelions and clover

Good nitrogen source

Covers the size of a basketball court

Works best with Scotts brand spreaders

Not for use on warm-season grasses

Scotts is one of the oldest names in the green industry, developing dozens of innovative products each year. The Turf Builder Plus is a fan favorite due to its effective control of weeds that reseed easily such as dandelion and clover. It includes a healthy dose of nitrogen, expressed in its ratio of nitrogen, phosphorus, and potassium (N-P-K ratio), keeping grass green and growing late into the season.

Like most weed and feeds, you apply Turf Builder Plus when rain is not in the forecast, to ensure it doesn’t wash away (but it is recommended to apply to a wet lawn). Application is a breeze: Simply follow the illustrated, easy-to-read directions on the bag, add to your spreader, and fertilize away. While Turf Builder works on an impressive number of grass types, it isn’t recommended for several warm-season southern grasses such as the ever-popular St. Augustine.

NPK Ratio: 28-0-3︱Type: Slow Release︱Application: Granular

Fertilizers rely on three major nutrients—nitrogen, phosphorous, and potassium (chemical symbol K) —to keep grass in weed-fighting shape. Expressed as product’s N-P-K numbers, they reflect each nutrient’s percentage by weight. So a product with an N-P-K ratio of 28-0-3 would have 28 percent nitrogen, zero percent phosphorus, and 3 percent potassium. Understanding this ratio helps you make the best choice when selecting a weed and feed to help keep your beautiful lawn looking good!

Best Budget: GreenView Weed & Feed

Vast broadleaf weed control

Not commonly found in garden centers

Slower acting than others

Greenleaf might be light on price but it goes heavy on weeds! Boasting control of over 250 broadleaf species, a 13-pound bag should be enough to cover a yard the size of a basketball court. The heavy nitrogen allows for quick green-up without the risk of burning your lawn. The zero-phosphate formula helps prevent runoff into nearby waterways, ensuring you don’t contribute to algal blooms.

The slow-release formula feeds the soil and aids in water retention to help protect from heat and drought during the summer months. Recommended for most grass types, this weed and feed only needs to be used twice a year to guarantee results.

NPK: 27-0-4︱Type: Slow Release︱Application: Granular

Best Splurge: Pennington UltraGreen Weed & Feed

Extended feeding time

Kills over 250 weed varieties

5% iron helps keep grass green

Not for St. Augustine Grass

Pennington features high-quality products and are a staple brand for golf courses and sports stadiums. The UltraGreen weed and feed claims to kill over 250 broadleaf weeds, including dollar weed, clover, and henbit. Both a quick and slow-release formula; it allows grass to green up quickly while slowing releasing nutrients over 3 months.

As with several other brands reviewed, you can use UltraGreen on just about any grass type, northern or southern, with the exception of St. Augustine. Distinctive to the formula, Pennington always offers of a shot of iron, a staple ingredient in constructing green grass. The resealable bag makes it easy to store leftovers, and the coverage size of 5,000 square feet (about the size of a basketball court) makes it useful for just about all lawn sizes.

NPK ratio: 30-0-4︱Type: Slow and quick release︱Application: Granular

Best Organic: Espoma Organic Weed Preventer

Abundant nitrogen for green-up

Easy to use, with clear directions

Works on all grass types

Doesn’t kill existing weeds

Espoma is the oldest organic company in the green industry. This product contains corn gluten meal, a natural source of nitrogen, aiding quick green-up, and which the U.S. Environmental Protection Agency (EPA) has found to lack adverse effects on humans and animals . Application is easy with a spreader, and a 25-pound bag covers up to 1,250 square feet, a fourth of the size of a basketball court.

Applied twice a year, this weed and feed is a preventative, to stop weeds before they emerge. (If you are trying to kill weeds that are already present, this is not the weed and feed for you.) The corn gluten that prevents feeds also feeds the grass, giving it a rich green color and strong roots.

NPK Ratio: 9-0-0︱Type: Slow Release︱Application: Granular

Best Spray: Scotts Liquid Turf Builder with Plus 2 Weed Control Fertilizer

Easy and fun to apply

Goes to work quickly

Large coverage area

Cannot use on St. Augustine Grass

Requires a hose to apply

Scotts Turf Builder comes in a handy liquid form. Great for those with small spaces, you can easily fertilize and control weeds with a single spray. The bottle features a hose attachment, which allows you to cover about a basketball-court-size area from 4,000 square feet (cool-season grasses) to 6,000 square feet (warm-season lawns). It’s fun, too!

Controlling post-emergent weeds including ivy, knotweed, clover, and dandelions, you can use this multiple times a year with just about every grass type. (Once again, owners of St. Augustine Lawns are out of luck.) The spray allows for easy uptake of needed nutrition and serves as a healthy vitamin boost for your grass.

NPK Ratio: 25-0-2︱Type: Quick Release︱Application: Liquid

Best for St. Augustine Grass: Fertilome St. Augustine Weed & Feed

Safe for St Augustine and other warm-season grasses

Offers preventative and post-emergent control

Only covers 2,500 square feet

Not usable on Bermuda grass

Southern homeowners love St. Augustine grass for its hearty ability to stand up to intense heat and high traffic. However, many major weed and feed brands explicitly instruct not to use their products on the Southern classic. Florida brand Fertilome offers a St. Augustine-exclusive blend that serves as both a preventative and post-emergent weed-destroying superhero. In fact, the manufacturer specifies to use this product only on St. Augustine, Zoysia, Centipede, and carpet grass lawns.

You need to apply this product only once, in early spring, and the slow-release formula continues to feed the rest of the season. This product only covers up to 2,500 square feet (half a basketball court), half the coverage offered by the other brands tested.

NPK Ratio: 15-0-4︱Type: Slow Release︱Application: Granular

Best Weed Preventive: Preen One LawnCare Weed & Feed

Kills up to 250 types of weeds

Covers 5,000 square feet

Not for use on St. Augustine grass

For a post-emergent weed world, Preen One is our top choice for banishing them quickly. It also works as a pre-emergent, making sure developing seeds from existing weeds do not make their appearance again next season. Controlling over 250 weeds, including clover and dandelions, it also feeds your lawn for up to 2 months. The manufacturer also claims the product kills other common lawn weeds, including dandelions, chickweed, thistle and clover, and prevents crabgrass and its cousins from coming back.

As a feeder, the product contains slow-release nitrogen for steady nutrition. Homeowners living near waterways can feel confident of using this zero-phosphate formula without worrying about runoff. While this product is not to be used on Southern grasses, such as St. Augustine and colonial bentgrass, it can be used for other, common warm-season grasses such as Bermuda and Zoysiagrass, You can purchase Preen One in three sizes: 9-, 18-, and 36-pound bags, which can cover areas from half a basketball court to just under an Olympic swimming pool.

NPK Ratio: 24-0-6︱Type: Slow︱Application: Granular

Best for Cool Season: GreenView Fairway Formula Spring Fertilizer Weed & Feed with Crabgrass Preventer

Kills over 200 types of weeds

Has both quick and slow release nutrients

Covers 15,000 square feet

Should not be used on new lawns

Crabgrass is the bane of many homeowners because it disrupts a lawn’s smooth texture. Most prevalent in cooler-season grasses, it can be near impossible to get rid of once it settles in. This product’s slow-and-quick- release formula knocks out crabgrass, as well as 200 other weeds; the manufacturer claims its proprietary formula kills dandelions and seedling crabgrass at the same time. As a feeder, its nutrients slowly release over a 3-month period, providing lasting nutrition for established lawns.

The spring lawn-care product is a pre-emergent, meaning it is designed to prevent crabgrass and other undesirables from growing. However, it is not meant for use on freshly planted lawns, as it is likely to burn new growth. Also, this product is not available for sale in Alaska, Hawaii, and California. And, it was hard to track down due to issues with shipping it to certain states, so bear that in mind as you plan your search.

NPK Ratio: 24-0-6︱Type: Quick and Slow Release︱Application: Granular

Scotts Turf Builder is our pick for Best Overall Weed and Feed. Not only does it suppress 250 species, but it is also easy to use, and works on just about every grass type. For a product that busts weeds but not your budget, we recommend GreenView Weed & Feed for its heavy nitrogen content, allowing for quick green-up.

What to Look for in a Weed and Feed

Before buying any fertilizer product, keep in mind these important considerations to make sure you buy the best to suit your grass type, climate, and timeline.

N-P-K Ratio

All fertilizers, including those with added herbicide, rely on the three big nutrient needs to keep grass in weed fighting shape. Nitrogen, Phosphorous, and Potassium are generally listed front and center on any fertilizer bag you pick up, with the percentages of package weight listed clearly. Understanding what each one does helps you make the best choice when selecting a week and feed to help keep your plants healthy while enlisting a weed suppressant for assistance.

  • Nitrogen, listed first, is the most important for overall growth. It promotes healthy leaf development and is responsible for the bright green we love to see in lawns. A shot of nitrogen helps take away the stress endured from competing with weed species.
  • Phosphorous, the second listed number, is responsible for developing healthy roots. Most lawns tend to be deficient in phosphorus, and grass is not a notorious heavy phosphorous feeder. Fertilizers containing phosphorus are not permitted for lawns near waterways or in a county with a fertilizer ban during the rainy season. Phosphorus deficiency shows up as reduced vigorous or slowed growth ; a quick soil test can let you know if your lawn is phosphorus deficient.
  • Potassium, also known as potash, helps roots dive deeper into the soil, allowing grass to increasingly resist stressors such as heat, drought, and weeds. While nitrogen allows for quick growth, it is necessary to encourage those roots to stretch out and not become reliant on a quick fix from a heavy nitrogen source. It also gives weeds less space to take over.

Application Type

Fertilizers and weed and feeds are sold in slow-release and quick-release formats. Liquid weed and feeds are always quick-release, meaning they are water-soluble; plants can take them in a short time, generally within a month. Non-soluble slow-release weed and feeds are sold in a granular, polymer-coated format. As the product breaks down, it slowly releases nutrients, which the plant can take up as needed. This also allows for fewer applications, as slow-release products can take 3 months to fully break down. This also helps prevent the likelihood of burning plants through too much nitrogen fed too quickly. Many weed and feed products mix both slow and quick release, working quickly on weed suppression while slowly feeding the plant. This helps increase the overall rigor, which decreases the likelihood of opportunistic weeds from elbowing in.

Grass Type

The United States is divided into many gardening zones, based on climate. Grass suited to North Dakota likely cannot handle the intense heat of Florida summers. To keep it simple, grass is defined as cool-season Northern (like Kentucky bluegrass) or Southern (like St. Augustine). Identifying turf grass can be challenging but it is essential for making sure you select an. appropriate weed and feed. If not, the herbicide component may kill turf grass. Manufacturers must list the types of grass best suited to each product, so be sure to consult first before you use.

If you believe your lawn comprises multiple types of turf grass, always err on the side of caution and select based on cool- or warm-season grasses.

The basic premise of a weed and feed is to include a herbicide and nutrition in one shot. When lawns are healthy, weeds have less opportunity to outperform your grass. Generally, the herbicide is 2, 4-D or Dicamba, which are in amounts designed to target weeds but not the surrounding grass.

Pre-emergent weed and feeds concentrate on getting weeds before they appear. Most noxious weeds produce numerous seeds, which pre-emergents help make sure never make it to adulthood. Consider a post-emergent when weeds are already problematic.

For best results, apply a weed and feed at the start of growing season, when grass is no longer dormant and weeds are getting ready to pop. Depending on where you reside, that could be late March or early April. Weed control is all about strategy, and timing is at the heart of it. Plan on fertilizing and using a pre-emergent in early spring, and follow up later with a post-emergent, as needed.

For most fertilizers and weed and feeds, wait at least 48 hours before watering. This window leaves enough time for the herbicide to make its way into the weeds, leaving less residue to potentially wash off. Pre-emergent weed and feeds are less finicky, allowing you to get away with 24 hours. If possible, try to time your application so rain doesn’t spoil weed-preventative plans.

Be sure not to overwater! This can cause the herbicide to wash away along with all the nutrition you just added.

The Best Weed Killers for Your Lawn for 2022

Wondering how to choose the best weed killer for your lawn? Read on to learn how weed killers work, how to apply these products, and our recommendations for the top weed killers.

If your lawn is getting out of control with weeds, hand pulling them just isn’t going to cut it. Sure, you can tug out a few by the root, but it may be difficult and time-consuming to do that for your entire yard. That’s where weed killers come in, often the best method for lawn weed control.

There are tons of lawn weed killers on the market, so it may be difficult to choose the exact right one for your lawn. The This Old House Reviews Team has rounded up the top weed killers for 2022—and how to choose them. For extensive weed control and lawn care, we recommend considering a lawn company like TruGreen.

Identifying Weeds

Before you can choose the proper weed killer, you’ll have to determine exactly what type of weed you’re dealing with. Different weed types require different treatments—what’s effective for one may do little or no damage to another.

There are three main categories of weeds: broadleaf, grassy, and grass-like.

1. Broadleaf weeds

These weeds have broad, flat leaves, so it’s unlikely you’ll mistake them for grass. They thrive in soil that’s lacking key nutrients, and they come in different types—annual, biennial, and perennial, so different broadleaf weed varieties require different chemicals depending on their life cycle.

Examples of broadleaf weeds include dandelions, ground ivy, clover, chickweed, dollarweed, thistle, and oxalis.

2. Grassy weeds

Grassy weeds have leaves that look like grass blades, and they grow one at a time. Examples of grassy weeks include crabgrass, quackgrass, goosegrass, and foxtail.

3. Grass-like weeds

This weed type resembles grass, but its leaves are more tube-like and triangular than flat. Examples of grass-like weeks include garlic, nutsedge, and wild onion.

How Weed Killers Work

Weed killers work by using chemicals that kill the weed or prevent its growth. There are a variety of different herbicide types to treat weeds at different stages of their life cycle—or before they even sprout. Here are the main characteristics to consider when choosing your specific weed killer.

Pre- or post-emergent

Pre-emergent weed killers target weed seedlings before they get a chance to sprout. If weeds have already popped up, this type won’t help. Post-emergent weed killers are designed to eradicate weeds in their active growing season. You apply post-emergent weed killers directly to the plants’ leaves.

Selective or non-selective

This aspect is critical. Selective weed killers eliminate weeds without harming beneficial plants nearby, while non-selective herbicides will damage all nearby plants, even if they’re beneficial.

Systemic or topical

Systemic weed killers attack the entire plant, including the roots. Topical herbicides, on the other hand, only kill the areas where the weed killer is applied.

Persistent or non-persistent

Persistent weed killers stay active after you apply them to prevent future weeds. Non-persistent weed killers don’t offer ongoing weed control.

How to Apply Weed Killer

Even if you select the right weed killer, applying it incorrectly can make your efforts fruitless, and the wrong application can cause complications.

Many weed killers need to be diluted with water and put in a spray bottle. The product’s label will explain precisely how much water and weed killer you’ll need to combine. Some weed killers, however, come in granular form. Solid weed killers must be applied with a spreader.

When applying weed killer, timing is everything. You don’t want to apply weed killer immediately after mowing your lawn since that could harm your tender grass. The same goes for fertilizer. In both cases, wait several days before applying weed killer.

The weather also plays a role in when to apply weed killer. Applying weed killer when it’s too hot can stress your grass, and applying it right too soon before it rains means it can wash away before it gets absorbed.

The 3 Best Weed Killers

Here are the top three best weed killers for 2022.


This powerful, fast-acting weed killer battles the exterior part of the weeds it contacts as well as the root systems. It kills stubborn weeds very efficiently, and spraying weeds selectively will ensure your lawn stays intact.

How to Prevent Weeds

When it comes to tackling weeds, the best defense is a good offense. You should always take these steps to keep your grass hardy and robust, reducing the chances of weeds taking over.

  • Water deeply and infrequently—If you want your grass to have strong, deep roots, you need to water deeply and infrequently instead of choosing shallow, daily watering. With deep, sturdy roots, your grass can grow nice and thick and compete with weeds that may try to grow.
  • Mow high—Weeds need sunlight to grow. If you let your grass blades grow taller by setting your lawn mower to the first or second highest setting, the grass will grow tall enough to cast shade on any weed seeds, preventing them from sprouting.
  • Feed regularly—Stressed lawns are more susceptible to being crowded by weeds. Feeding regularly will keep your lawn lush and make it less hospitable to enterprising weeds.

Our Rating Methodology

To provide readers with the most objective, accurate, and detailed recommendations, the This Old House Reviews Team continually researches lawn care service companies on the market. We take the following steps to obtain up-to-date information about the industry and each company we review:

Best Weed and Feed Spray Buying Guide

Grass Type

Despite grass looking relatively the same – long, thin, and green – grass is actually a plant with many species. Like the varying species of one animal, different species of grass benefit from different things.

In terms of weed and feed, this means that some types of grass respond better to certain fertilizers, while others yield no result from them. Before buying and applying a weed and feed, you need to figure out which type of grass you have.

This is because some fertilizers can burn certain types of grass, so you need a fertilizer that will be both gentle and effective on you your specific grass species.

Types of Weed & Feed

There are two types of weed and feed solutions: granular and liquid. Both types have their own set of advantages and disadvantages.

Granular is the oldest type of weed and feed. It has been used for decades and is trusted by professionals. This being said, it also tends to be a bit more work to apply and can be hard to lift and carry from one place to another.

Liquid weed and feed is a new concept. It’s easy to apply, doesn’t usually require any preparation, and is a lot easier to carry form the front lawn to the back lawn than a big bag of granular product is. However, it hasn’t been tested as much and doesn’t have much of a reputation. It can also be expensive.

Lawn Size

The size of your lawn is going to play a huge role in which weed and feed you purchase. Although you could technically use any of the available weed and feed options that are safe for your grass, some prove to be better options than others.

This comes down to the volume of the product and the value you get for your money when you make a purchase and head outside to use the product. A large lawn is not ideal for small bottles of liquid weed and feed, for example. You’d need multiple bottles to get the job done!

Product Safety

If you have outdoor pets or children who like to play outside, you might want to pay special attention to the safety of the weed and feed you have in mind. While almost all weed and feeds use some sort of chemical, safety risks, and precautions can vary greatly by product and company.

Some weed and feeds are safe to touch within hours, while others can take two or three days to be considered safe to be around. This might not be practical if you have pets who go outside to use the washroom, or children who use the lawn for soccer practice.

Along with the safety of your children and pets, you also need to consider your own safety. Most weed and feeds aren’t dangerous to spread, but whenever you’re using a chemical it’s a good idea to at least put on a pair of rubber safety gloves. If you don’t feel safe using weed and feeds with chemicals period, consider opting for a natural weed and feed, which is likely to be much safer.

Post-emergent vs Pre-emergent Weed & Feed: What’s the Difference?

There are two varieties of weed and feed: pre-emergent and post-emergent. Knowing which of the two to look for is critical in order to treat your lawn without causing damage or wasting money.

Pre-emergent weed and feed is used to kill weeds before they grow, allowing you to apply it to laws that have already been established and have no current weed problems. It is, essentially, a preventative.

Pre-emergent weed and feed should be applied every year at the start of the spring season. This prevents the weeds from recovering from the prior treatment and re-growing, It’s ideal to use the product yearly because even if the previous year’s weeds have been dealt with, the wind is constantly moving weed seeds around and dropping them onto your lawn.

Post-emergent weed and feed is an herbicide designed for weeds that have already grown and are prominent and easy to see. Generally, the frequency in which you apply this kind of product is determined by how quickly the weeds appear in the yard.

Weed & Feed Tips and Tricks

1. If you’re unsure of which type of grass you have outside, you can find out by taking a small sample to your local tree nursery or garden expert. Any experienced gardener will be able to take one look at your sample and decide which type of grass you have.

2. To boost the effectiveness of your product, mow your lawn 1-2 days before you apply it. Then, the clippings from the next three or four mows should be quickly discarded and not used as mulch or for flower beds, as they’re likely to contain chunks of weed that could start to grow.

3. Weed and feed products only work on broadleaf weeds. This includes an array of the most common weeds including dandelions, chickweed, and henbit, but excludes plants like crabgrass. You’ll need a different product to deal with weeds that don’t have leaves for the product to settle on.

4. Don’t skip the mowing! Before you use a weed and feed, be sure to lug out that old lawn mower and go over the lawn a day or two before. Although it’s not the most fun summer activity, it is necessary. Mowing allows weeds to better absorb non-systemic solutions and gives systemic solutions better access to the soil.

5. Take care to avoid spreading weed and feed on flower beds, vegetable gardens, or plants that you don’t want to kill. Weed and feeds target broadleaf plants and are not selective when it comes to whether the plant is a weed or not; if it touches a broadleaf plant, it will kill it.

6. When using weed and feed around flower beds or the edges of gardens, use a drop spreader to apply. Or, you can choose to cover the area you wish to protect with plastic until you have finished the application.

7. If you feel that you have applied too much product, the best thing to do is try and flush out the excess. You can do this by watering the area with 1-2 inches of water for a total of four days. Don’t apply any more product until the next season.

8. Avoid getting the product in your eyes or on your skin. Should the product get in the eyes, flush them for 15 minutes with clean water. If it gets on your skin, a thorough washing should do the trick; wear long sleeves, pants, and safety glasses for application.
