Before You Buy

Maintaining a healthy lawn includes mowing, weeding, watering, and fertilizing. However, fertilizing isn’t always necessary. Over-fertilizing your lawn will make the grass grow more vigorously, causing you to have to mow more frequently or lead to run-off which ends up in your local watershed.

Excessive fertilizing can result in lawn burn, which is when the nitrogen and salt levels in the soil are too high and cause yellow to brown strips or patches of dead grass. A lawn, as with any type of plant, only needs fertilizing if the soil lacks the vital nutrients to help it grow. In situations like these, fertilizing your soil is essential.

Types of Weed and Feed

Weed and feed comes in two forms: liquid and granular. Although the liquid forms are easier to apply and provide faster results, it’s more economical to use the granular form. Spray or liquid weed and feed are designed for small yards. Granular weed and feed covers more area, often 5,000 square feet or more, and are available in 18-lb bags and larger. Granular versions offer a better value for your money, but you do need to water your lawn after application for it to penetrate the grass.

Some weed and feed feature slow-release formulas so you don’t have to fertilize as often. However, to achieve good results plan on treating your lawn at least once every eight weeks from the start of spring.

What to Consider When Choosing the Best Weed and Feed

Type of Turf Grass

The best weed and feed product for your lawn depends on the type of grass you have. Grass species have different nutrient requirements, so not all of them are safe for every species of grass. Using the wrong product can damage your grass. In general, grass species are divided into two categories: warm season and cool season. The seasons do not refer to the time of year, but the climate and average soil temperature range.

  • Warm-season turfgrasses grow best with average soil temperatures between 80 and 95 degrees Fahrenheit. Warm-season grasses thrive in warmer climates found in the Southeastern and Southwestern United States and include Bahia grass, Bermuda grass, carpet grass, Saint Augustine grass, and zoysia grass (Japanese lawn grass).
  • Cool-season turfgrasses grow best with average soil temperatures between 60 and 75 Fahrenheit. Cool-season grasses thrive in the cooler climates of the Midwest and Northern regions of the United States. Some cool-season grasses are Kentucky bluegrass, perennial ryegrass, and tall and hard fescue.

Selecting a fertilizer and weed killer that’s compatible with your grass species will give you far better results.

Nutrients

To grow a lush lawn, your soil needs to have essential nutrients. Fertilizers temporarily add nutrients to the soil. Fertilizers denote their nutrient ratios as NPK. This denotation represents the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the product. This is how the nutrients help grass:

  • Nitrogen helps the grass to grow properly and develop a green color.
  • Phosphorus helps to develop strong root systems.
  • Potassium protects plants from disease, drought, and cold.

There are at least 11 states that ban phosphorus fertilizer use or sale. Luckily, many lawn weed and feed products available have adapted to this and have removed phosphorus from the product. Don’t worry—the weed and feed will still green up and thicken the grass without the additional phosphorus.

Fertilizers can also contain secondary elements and micronutrients needed for healthy growth such as sulfur, calcium, magnesium, boron, iron, molybdenum, zinc, copper, chloride, nickel, and manganese. To find out exactly what nutrients your lawn needs can be determined by conducting a soil test. You can either purchase a test to use at home or take a soil sample to your local cooperative extension testing office.

Targeting Weeds

Many fertilizers also have built-in herbicides or weed preventatives. Some products are better at killing certain types of common weeds and pests than others. In general, most weed and feed target common types of broadleaf weeds including plantain, chickweed, creeping charlie, dandelions, and clover.

Weed preventers, or pre-emergent weed killers, block weed seeds that are already in the soil, like crabgrass, poa annua, chickweed, and henbit, from germinating. Identify the type of weeds that are infesting your lawn and then make sure you choose a product that’s made to take care of it.

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.

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.
