The 8 Best Weed and Feeds in 2023

Whether you’re looking to keep your lawn healthy and lush year-round or trying to bring back some of the vibrant green to your yard, a weed and feed can be of great help. They get rid of tough, stubborn weeds while simultaneously helping your lawn grow lush and green.

But what exactly is a “weed and feed”? How does it work? How do you use it? And what should you consider before buying this product? Below, we have detailed answers to all these questions and more, as well as the top 8 weed & feeds currently on the market.

How to Choose a Weed And Feed: A Buying Guide

Weed and feed is a single, generic term that describes a wide range of lawn chemicals formulated to achieve two main goals: kill certain types of weeds and support the health of existing grass in your lawn.

With one application, this array of products is generally designed to boost your lawn’s ability to take up water and added nutrients, helping it grow better and stronger.

From there, as your lawn starts to grow, the new healthier grass discourages the propagation of unwanted weeds. This means that over time, you’ll need to use less and less weed and feed.

However, if you begin to notice that your lawn growth is declining or weeds are appearing more, you can re-incorporate weed and feed application into your plant care routine.

Types of Weed and Feed

The herbicides usually used in weed and feed products come in two major types: pre-emergent and post-emergent. Not only does knowing which one to buy and when to apply it depend on the weed situation you’re currently dealing with, but it’s also crucial to successfully getting rid of weeds and generating a healthy lawn.

Pre-emergent Weed and Feed

This type acts to kill unwanted weeds before they develop. This means that if your lawn is still under control and you can’t yet see grown weeds, a pre-emergent weed and feed is the right choice for you.

To achieve the best outcome, be sure to apply pre-emergent weed and feed once every year at the beginning of spring. This way, weeds are less likely to come back. 

Keep in mind that if you manage to clear out the unwanted weeds the previous year, there’s a chance they could appear again because the wind is constantly carrying more weed seeds into your lawn. As such, even if you keep your lawn perfectly weed-free, you should apply pre-emergent weed and feed each year.

Pre-emergent herbicides work best against Japanese stilt grass and crabgrass.

Post-emergent Weed and Feed

This type acts to kill unwanted weeds after they’ve already developed. How often you should use it and how much you should apply varies according to the number of weeds taking over your lawn.

If you can see a lot of weeds choking out the grass, a post-emergent product is probably what your lawn needs. Consider asking for advice from a local lawn care center or landscaper.

Post-emergent herbicides work best against nimblewill and bermudagrass.

When You Should Apply It (Not Too Early/Not Too Late)

Whether you’re using a pre-emergent or post-emergent weed and feed, the most important rule when it comes to product application is to never be too early or too late.

Season and Water Presence

It’s critical to treat your lawn when the unwanted weeds are growing actively early in the season. As such, if you apply your product during the winter, you won’t see any results in the spring and summer after.

Additionally, you should avoid applying weed and feed when it’s expected to rain. Although spreading weed and feed is preferably done on a damp or wet lawn because it allows the product to better reach the weeds, there’s no need for lots of water.

Using a sprinkler or waiting until right after rain is usually enough to maximize application efficiency. However, there should be no rain or lawn watering for two days after application.

This water break gives the herbicide time to stick to the weeds and get absorbed by them. Otherwise, the excess water will wash away the product. Though if that happens, you shouldn’t immediately re-apply the product due to the risk of over-feeding the lawn and potentially causing a lawn burn.

Time of Day

You can apply pre-emergent weed and feeds any time of day as their mechanism of action involves creating a soil barrier to prevent the growth of weeds.

On the other hand, the time of applying post-emergent weed and feeds depends on whether the product contains non-systemic or systemic herbicides. Check the label on the container to make sure.

The non-systemic type damages plant tissues, so you can apply it any time during the day.

However, the systemic type has to get absorbed through the roots to enter the weeds as they’re actively growing, so the time of using systemic herbicides changes according to the growth region.

Does Your Lawn Need a Weed and Feed?

If any of the following scenarios apply to your lawn, then it’ll benefit from a weed and feed:

  • Suffering from a weed infestation
  • Prone to weed infestations
  • Looking dull
  • Requiring extra nutrients

How Does it Work?

Weed and feed products contain nutrients in the form of minerals and herbicides that are either non-systemic or systemic. The nutrients promote healthy grass growth, whereas herbicides kill unwanted weeds.

The mechanism with which these chemicals work depends on the form they come in. Generally, weed and feeds are available in two forms:

  • Granules — this form consists of tiny granules coated with a herbicide. You apply such a product by spreading the pellets across your lawn when it’s damp or wet so that they stick to the weeds. The water then makes contact with the granules, dissolving the herbicide coat and releasing the killer chemicals as well as the nutrients.
  • Liquid — this form consists of liquid chemicals mixed with water. You apply such a product via a sprayer to easily cover your lawn. It doesn’t matter whether the grass is wet or dry upon application.

The choice here is up to your preference. But whatever you end up picking, be sure to closely follow the instructions indicated on the container to achieve the best outcome.

Additionally, since certain herbicides work best against certain types of weeds, carefully reading the labels can help you make a better decision.

Soil Testing

Weeds in your lawn aren’t the main problem, they’re actually a symptom of a bigger problem. As such, weeds offer a natural way for soil testing your lawn as different weeds can indicate various issues in your lawn. For example:

  • Chickweed indicates a high nitrogen content.
  • Crabgrass indicates a low level of nutrients, especially calcium.
  • Dandelions indicate a depleted compact soil that lacks calcium.

How to Apply Weed and Feed

Granular weed and feed: You apply such a product by spreading the pellets across your lawn using a spreader or by hand. The grass has to be damp or wet so that the granules stick to the weeds. Then, when the water makes contact with the pellets, it dissolves the herbicide coat and releases the chemicals as well as the nutrients.

We recommend that you use a spreader for application to dispense the proper amount evenly over your lawn. If you spread too many pellets in one area, they can damage the grass. Not to mention, overusing weed and feed can produce harmful runoff.

Liquid weed and feed: liquid products are a popular choice among homeowners because they contain already diluted chemicals, making them safe. You can buy liquid weed and feed in bulk or smaller containers fitted with a sprayer nozzle for extra convenience.

How Long Does it Work

Post-emergent weed and feeds can show initial results within four to seven days, though they may take up to three weeks to completely eliminate weeds. As for pre-emergent herbicides, they act even before you can see weeds and they remain active for up to eight weeks.

Regardless of the type of your weed and feed, your application frequency shouldn’t exceed twice per year.

When to Water After

Don’t water your lawn for two days after application. This water break gives the herbicide enough time to stick to the weeds and get absorbed by them. Otherwise, the excess water will wash away the product.

If that happens, you shouldn’t immediately re-apply the product due to the risk of over-feeding the lawn and potentially causing a lawn burn.

Key Considerations for Buying Weed and Feed

Granular vs. Liquid Application

Generally, weed and feeds are available in two forms:

  • Granules — this form consists of tiny granules coated with a herbicide. You apply such a product by spreading the pellets across your lawn when it’s damp or wet so that they stick to the weeds.
  • Liquid — this form consists of liquid chemicals mixed with water. You apply such a product via a sprayer to easily cover your lawn. It doesn’t matter whether the grass is wet or dry upon application.

The choice here is up to your preference and the size of your lawn. You can use granules on small to mid-size lawns without too much trouble, while larger lawns are easier to manage with liquid products.

Grass Type

Some types of grass respond better to particular types of fertilizer while others don’t do much for them. So, when you’re choosing a weed and feed, it should contain a fertilizer that’s compatible with your lawn grass.

Nitrogen and Other Nutrients

On the label of a weed and feed, you’ll see numbers that indicate the NPK value, which is the percentages of nitrogen, phosphorus, and potassium. You must check the amounts of these nutrients to make sure that the grass will get what it needs.

In smaller amounts, your lawn also requires other elements to stay healthy and strong such as molybdenum, zinc, cobalt, sulfur, and magnesium.

Weed Targeting

Some weed and feed products are better formulated to kill specific types of weeds than others. As such, you should figure out the type of weeds plaguing your lawn so you can pick a product that’s effective against them.

Common weeds that most of these products target include broadleaf weeds such as including dandelions, creeping charlie, plantain, and chickweed.
