10 Best Weed And Feed For Lawns Reviewed [+ Buyers Guide]

Whether you’re an experienced hand in the garden or novice, there’s one thing we all aspire to achieve, and that’s a beautiful luscious weed-free lawn. But as you may have already come to realize to achieve it we need to find a high-quality lawn fertilizer and a great herbicide to beat down those troublesome weeds.

That’s where the 2-in-1 weed and feed comes into play, feeding our lawn and dealing with weeds. But which one to choose, as there are so many. To help make your selection easier, our expert gardeners have reviewed the best weed and feed products from the top brands, and we will show you how to use them to maximum effect.

The Different Types Of Fertilizer

The 3 common forms of fertilizers are: liquid, granular and powder.

Liquid fertilizers must be diluted with water before spraying on the lawn using a hose attachment.

Powdered fertilizers also require water to be effective. They are normally spread by hand.

Granular lawn fertilizers are by far the most preferred products that can be spread on damp topsoil across your lawn. These types of fertilizers are easy to apply and offer better value for money. They will soak into your garden over time and feature slow-release formulas so you won’t have to fertilize your lawn as often.  

There are 4 types of fertilizers that can be in the granular, liquid or powder form. These are:

Organic and Inorganic Fertilizers

These are natural materials that mainly consist of compost and manure. Organic fertilizers work slowly and over the long-term to build up your soil.

Inorganic fertilizers, on the other hand, are made up of chemical ingredients that give your garden a quick boost of nutrients. 

Nitrogen Fertilizers

Nitrogen is a vital nutrient that almost all plants need to continue growing. All organic and inorganic fertilizers contain sources of nitrogen at different ratios based on the type of plant or shrub you are growing. 

Phosphate Fertilizers

All plants need phosphate throughout their growth cycle to strengthen their root system.

Potassium Fertilizers

To encourage stronger roots and the ability to fight off diseases, plants need this vital nutrient for healthy growth. 

Looking For Lawn Deficiencies  

Anyone who is new to the world of gardening must learn the importance of lawn nutrients. To increase your lawn’s ability to absorb water and sunlight, you must provide it with a healthy root structure that can withstand pests and diseases. Nutrient-deficient lawns tend to look patchy or discolored. By adding the right fertilizer to your lawn, you will restore these patches and boost growth. 

There are different fertilizer blends that contain vital nutrients and minerals as well as micronutrients. These nutrient-rich products will promote green grass growth that all gardening enthusiasts love to see. 

Most fertilizers have a combination of many different nutrients, including carbon, iron, manganese, boron, and calcium. However, before you buy fertilizer for your lawn, it’s important to test your soil. 

For instance, alkaline soils are most commonly deficient in iron. The symptoms of iron-deficient lawns include yellow grass with a mottled appearance. Potash deficient grass can also turn yellow and brown. 

Without a soil test, there is no way of knowing which nutrients your lawn is deficient in, so before choosing a fertilizer, make sure you read the next section on how to test your soil.  

Testing Your Soil Step by Step 

Before deciding on which fertilizer will best suit your lawn needs, it’s important to take a soil test. There are four basic types of testers: analog, digital, chemical, and professional testing.

While you can take a sample of your soil and get it tested at a nursery, I have a quicker and more convenient solution for you. I used Luster Leaf capsules to test my soil at home. This affordable chemical soil tester analyzes the vital nutrients and pH levels of the soil, so if you don’t need 100% accurate results, then this type of test kit will be very cost-effective. 

Whichever soil tester you choose, most are quite simple to use. Follow these quick steps to test your soil at home: 

1. Take a small amount of soil preferably from around 3 inches deep and place it in a vial or tube.

2. Add water to fill the tube before dropping a colored capsule in the water. Make sure the capsule color matches the vial’s lid color. Each color relates to the soil nutrient you are testing.   

3. Shake the vial and wait as per the tester’s directions. 

4. Now compare the color of the liquid to the enclosed color chart to help you estimate the nutrient levels of the soil.

Reading Fertilizer Labels 

After obtaining your soil’s test results, it’s time to choose the right fertilizer based on the ratio of nitrogen, potash, and phosphate on the label.

All fertilizer products display three bold numbers that specify the ratio of vital nutrients. The first number is the amount of N (nitrogen), the second is the amount of P (phosphate) and the third number is K (potash).

To give you an example, a bag of fertilizer will contain the numbers 10-10-10 on its label, which means it has 10% nitrogen, 10% phosphate, and 10% potash. These numbers will help you decide which fertilizer is most suitable for your specific plant or shrub.

How To Apply Weed And Feed 

Every weed and feed product has its own specific application instructions, which must be followed for safety and for optimum results. But to give you a general idea of how to apply weed and feed, here are some guidelines:

1. Mow and water the lawn two days before applying weed and feed. This helps ensure even distribution of the granules in the wet lawn.

2.  Extreme temperatures will adversely affect your lawn’s tolerance so always choose a day when temperatures are higher than freezing but below 80 degrees Fahrenheit.

3. Don’t apply weed and feed immediately after heavy rain. Sure, you want the lawn to be moist but it shouldn’t be soggy!

4.  Using a rotary or drop spreader, follow the exact instructions of the particular weed and feed product you’re using to apply the granules in your lawn. Cover the area evenly by walking back and forth across the lawn.

5. If you’re using a spray weed and feed, attach the liquid bottle to your garden hose and apply it in a precise pattern as per the instructions to ensure full coverage.

Most weed and feed products require more than one application to yield results. It is, therefore, important that you carefully follow the directions so as to avoid burning your grass. 

When To Use Weed And Feed 

Applying weed and feed during winter will have no effect on the lawn in the next growing season. To get the most out of your 2-in-1 product, you need to get the timing right. As a general rule of thumb, apply weed and feed in the active season during the last week of March or early April.

While keeping pesky weeds out of your lawn can be a yearly struggle, with a comprehensive strategy, you can keep your lawn green and weed-free. Any weed and feed product you buy will have the exact details of when to apply the formula for best results so always read the label.  

How Long Does Weed And Feed Take To Work?

Assuming you’ve chosen the right product based on your grass and weed type, (don’t worry, our reviewed products specify all this!) it usually takes between 4 days and 1 month to notice results. Post-emergent weed and feed formulas stop the existing weeds from growing, while the pre-emergent formulas will stop weeds from emerging in the first place. Most pre-emergent herbicides actively work for up to 2-3 months starting from spring. Any weeds that germinate during this period will die.   

Does Weed And Feed Work?

Since the timing of the application determines the effectiveness of the weed and feed, many people might think that such products don’t work or are too harsh on their lawn. 

If applied too early in the season, your lawn can get more fertilizer than it needs. Most types of grass need more nutrients when they are actively growing in spring. This is why most weed and feed formulas are extended-release and should be applied early in the growing season.  

If, for example, you apply a pre-emergent weed and feed too late in the growing season, (like in the middle of summer) the weeds will have already been established and the grass will be brown, thus making the product ineffective.

So as you can see, it is all about getting the timing right. Again, always follow the product’s application instructions for ideal results.  

Best Weed and Feed For Lawns Conclusion

If you’ve been looking for the best weed and feed for lawns, we believe all of the products we’ve reviewed make a great option. That said, our top 4 picks stand out in terms of effectiveness, value for money, and proven track record.

To help you decide, why not consider a top-rated product from the reputable brand, Scotts. The company’s weed and feed products adequately cover a lot of ground and don’t require frequent applications to yield great results. There is also the fast-acting product from Pennington that won’t burn your grass and eliminates up to 250 types of weeds. Whichever product you choose, we’re certain your lawn will turn from lame to lush in no time!
