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!
GreenView Fairway Formula Fertilizer – Best Pick
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.
Preen One Lawncare – Runner Up Pick
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.
GreenView Weed and Feed Review – Budget Pick
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 Review
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
Our final choice in this review is the BioAdvanced 3-in-1 Lawn Fertilizer and Herbicide. This product is effective at killing and controlling the growth of several weed varieties, including white clover and dandelions. A single application can last up to 6-months, and keep your lawn looking great throughout the summer.
This formula is ideal for southern grasses like Bermuda grass, centipede grass, zoysia grass, and Saint Augustine. The slow-releasing action of the granules means you only need to feed in the early spring and then at the beginning of June. A bag is 12.5 pounds, and it covers up to 5,000-square feet.
One application produces a noticeable difference. Regular use keeps grass healthy and weeds at bay. Kills weeds that other formulas can’t.
It takes time to dissolve in water. Not suitable for zoysia grass.

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
