If you desire a beautiful, lush lawn, you will have to put in the effort and most importantly, time into the myriad lawn care tasks. Apart from mowing your grass regularly to maintain its appeal, you need to set a great foundation for protection from rampant weeds that can threaten your lawn’s very existence.
Getting rid of weeds from your lawn is a daunting task to say the least, but one that must be done to improve your lawn’s ability to absorb water and essential nutrients. Weed and feed is comprised of two components — weed meaning herbicides and feed for fertilizer, and is available in several different options, geared towards varying lawn types.
Since weed and feed is a single product that serves two different purposes, applying it to your lawn saves you both time and money. However, it is important to fortify your lawn with the right weed and feed, or else it may do more harm than good. That said, here’s a list of 6 top-rated weed and feed options you can use to nourish your turf.

Applying granular weed requires a bit more attention than liquid weed and feed because you need to prevent the granules from drifting away into the storm drains. If you’re using liquid weed and feed, make sure you spray in a precise pattern and evenly so that you cover the entire lawn.
After application, you will have to keep children and pets away from the lawn for a week or two or until the residual product has washed away. And as a reminder, follow the manufacturer’s instructions carefully to use the product the right way, and without causing harm to your lawn and others.
Weed and Feed Buying Guide
First things first, weed and feed is not to be confused with fertilizers, because the latter does not kill weeds. Weed and feed is generally available in granular form, but there are some liquid options that you can use to kill weeds and fertilize your lawn. Adding to this, they should be spread across your lawn evenly and helps proactively get rid of weeds.
Fertilizers only feed your lawn with nutrients and are not a weed control solution. Therefore, you should ideally use both a fertilizer and herbicide to grow a lush lawn. But if your lawn is plagued with weeds, using a single weed and feed solution makes sense, as just one application usually works for weeks, and all through the summer.
Does Your Lawn Need Weed and Feed?
You should refrain from applying any lawn care products if it doesn’t need them. If you have only a small number of weeds in your lawn, then a manual weed removal tool may be useful for you. So, if your lawn is exceptionally unhealthy, and you’ve got a weed problem, then a weed and feed treatment is right for you.
However, if there’s a specific area of your lawn that is indeed exceptionally healthy, another area that’s flourished with weeds, then you may want to reconsider using weed and feed, as it is meant to be applied to your entire lawn.
Liquid Weed and Feed vs. Granular Weed and Feed
Both liquid and granular weed and feed products are readily available, but there are a few differences between the two, which can make one better than the other depending on your needs. For starters, liquid weed and feed is just that — a fertilizer and herbicide in liquid form that is applied by simply spraying it over the affected area.
Granular weed and feed aka dry weed and feed looks similar to granular fertilizers, and are basically small size pellets coated with weed-killing herbicides. These products can be applied using either drop or push spreaders and are designed to eliminate actively growing weeds.
Results from both liquid and dry weed and feed can be very effective, but the latter takes a bit longer to stick to the leaf of the weed in order to be absorbed and travel down its root system. So, if you don’t mind waiting a bit longer yet want a highly effective fertilizing and weed combo solution, granular weed and feed is a good option.
What to Look for in the Best Weed and Feed?
Both dry and wet weed and feed contain herbicides and fertilizers, which collectively kill weeds while simultaneously providing essential nutrients to your lawn. There are a few factors to consider when selecting a weed and feed product that’s right for your lawn.
Nitrogen content – grass needs nitrogen to grow lush and green, but extremely high nitrogen content such as over 90 percent could actually burn your lawn. Along with nitrogen content, it is a good idea to buy weed and feed that contains small amounts of potassium and phosphorus, which work well to dilute the concentration of nitrogen.
Weeds it kills – while most of the best weed and feed products are formulated to kill several major types of weeds, some don’t so buy one that can help you control the weed you’re dealing with.
Grass compatibility – just like weeds, some weed and feed can be used on both northern and southern lawns and certain types of grasses, whereas others are all-rounders, and can be used on most grass types.
The ideal conditions to apply weed and feed is when you have a minimum of two inches of new growth, and when the weather is clear, with no rain forecast for at least a couple of days.
Windy and rainy conditions can cause the weed and feed to become less absorbent to the weeds, and in worse cases drift away, and be absorbed by favorable plants. The herbicides in weed and feed will be highly ineffective if it rains in the next 48 hours after application, where even a light shower can put an end to your efforts.
How to Apply Weed and Feed?
As mentioned earlier, weed and feed should be applied across your entire lawn, and not just to certain problematic areas. You can apply liquid weed and feed using a sprayer, and dry weed and feed using a spreader such as the Scotts Southern Weed & Feed + Wizz Spreader.
Avoid applying weed and feed more than twice to the same area, and only to the surface of the soil, because the herbicides must be absorbed by the leaves of the weeds in order to kill them.
Spraying directly on the soil is a waste of the product, and may even harm healthy and ornamental plants. Most importantly, do not mow your lawn before application, as doing so will get rid of the leaves of the weeds the herbicide is supposed to stick to.
What to Do After Applying Weed and Feed?
Now that you’ve applied weed and feed, and the weeds you’ve targeted are dead, you’ve got some cleaning up to do! First, you should not mow your lawn for at least a week or even a bit longer, as this extra time will allow the weeds to absorb the herbicides better.
Once this waiting period has lapsed, do not apply more weed and feed, but rather put on a pair of gardening gloves, and pull any weeds that lived through the weed and feed application right down from their roots. After you’ve removed all the weeds including the dead weeds, you can now mow your lawn to prevent the spreading of their seeds.
When to Water After Weed and Feed Application?
Just like mowing your lawn, you don’t want to rush into watering your lawn after a weed and feed application. Your lawn should however be moist at the time of the application, but watering it right after the weed and feed treatment will wash it away, making it ineffective.
Since not all weed and feed products are the same, you should refer to the manufacturer’s instructions on the use of the product. But you should wait at least a week or so before watering your lawn after applying weed and feed.
Do Seasons Affect the Use of Weed and Feed?
Even though most weed and feed products mentioned on this list can be applied at any time of year, spring is typically the best time for application. You can generally find the best time to apply weed and feed according to your growth zone right on the manufacturer’s label.
How to Use a Weed and Feed Spreader?
Applying liquid weed and feed is a no-brainer by simply spraying the liquid evenly across the weeds and your lawn. But applying dry weed and feed can be a little bit tricky, as first, you need to decide on the type of spreader to use — broadcast spreaders or drop spreaders.
Both drop and broadcast feeders are push powered machines that share many similarities. Drop spreaders and broadcast spreaders are fitted with a hopper in the middle complete with adjustable holes at the bottom. The handlebar of both spreaders is equipped with a gauge, which allows you to adjust the size of the holes.
Drop spreaders are generally a good choice for small lawns, as they lay a trail of weed and feed the size of their hopper. Broadcast spreaders are a choice of professionals and are best for lawns over 4,000 square feet. Further, they can also spread the material over a wider area, which makes them a great choice for weed and feed treatments.
