The 6 Best Weed Killers of 2022

The Spruce / Sabrina Jiang

Weed killers help keep your landscape looking its best year-round, without invasive weeds, crabgrass, dandelions, or sedges hogging the spotlight. They can also save you time and energy pulling weeds, so you can relax and enjoy your yard. To help you find the right one for your outdoor spaces (since not every product is good for your yard or needs), we researched dozens of weed killers and tested these picks in our own backyards, evaluating each product on several key features, including ease of use, effectiveness, and value.

Our Top Picks

Best Overall

Spectracide Weed and Grass Killer Concentrate

4.6
Spectracide Weed and Grass Killer Concentrate

Amazon

What We Like
  • Kills all plants at the root

  • Works on walkways and patios

  • Rainproof after 15 minutes

  • Cost-effective

What We Don't Like
  • Pump sprayer recommended (not included)

  • Can kill unprotected grass and other plants

Spectracide is a popular choice for areas where quality results count, such as golf courses, sports stadiums, and turf grass. This weed killer earns our top spot on this list, because it is highly effective and can be applied to many different areas around your yard, including flower beds, around trees, and even hardscapes, such as walkways and patios, to keep them looking their best. We also appreciate that you can expect results the same day it’s applied, and it is weatherproof within 15 minutes, so you don't have to wait for a clear day to do the task.

This cost-effective 64-ounce container must be diluted first and then applied with a tank sprayer for best results (purchased separately). To save time, you can also purchase this product in a pre-mixed ready-to-use spray format. To achieve the best success and reduce spray drift, we suggest applying it on warm, sunny days with minimal wind.

Keep in mind that this effective weed-killing product kills all plants at the root, so you want to avoid using it on plants and grass you want to keep (or cover them up if need be, as we did while testing). It's also recommended to not mow the treated areas for at least a week, but you can plant new flowers or shrubs after 24 hours. This product should not be used near edible plants. Like all weed killers, make sure to keep it out of reach of kids and pets and wait a full 24 hours to dry before letting them near the treated areas. Aside from these few downsides, we think this is an excellent budget-friendly, effective weed killer.

Best Natural

Green Gobbler 20% Vinegar Weed Killer

4.2
Green Gobbler 20% Vinegar Weed Killer

Amazon

What We Like
  • Contains no harsh chemicals

  • Can be used in various places

  • No dilution needed

What We Don't Like
  • Weeds need to be pulled for best results

Many weed killers contain harsh chemicals; however, Green Gobbler Vinegar Weed and Grass Killer is glyphosate-free and made without synthetic ingredients. Derived from corn, it can take care of unwanted crabgrass, dandelions, clover weeds, white clover, mold, and more.

We tested this natural weed killer and successfully used it on driveways, sidewalks, concrete, mulch, and flower beds and didn't see weeds return, even weeks after application. We especially appreciated using this to get rid of weeds growing in the cracks of a driveway. However, we did have to pull the weeds after they were killed to ensure they did not come back.

You can expect to see visible results in less than 24 hours, and the manufacturer offers a 100 percent satisfaction guarantee. Because it is vinegar based, it is not weed-specific and can harm all grass and plants. Make sure you use it only in areas where weeds are present, not plants you want to keep.

What to Look for in a Weed Killer

Targeted Plants

Not all weed killers target the same plant species. If you need to kill weeds in your lawn, look for a selective formula that doesn’t kill grass along with the weeds. For a vegetable garden, make sure your chosen product is approved for use around edible plants. If you prefer to get rid of all vegetation, a non-selective formula is the best way to go. Our best for flower beds pick, the Fertilome Over The Top Grass Killer is an example of a selective formula that can be used around flower beds and vegetable gardens, as well as driveways and walkways. If you want a weed killer that you can use on a hardscape, where you are not worried about killing other plants or grass, the Ortho GroundClear Year Long Vegetation Killer is your best bet.

Longevity

Do you want your weed killer to work once, or would you prefer a formula that keeps vegetation from growing back for up to a few months? Or better yet, do you want a product that keeps weeds from growing in the first place, like our best pre-emergent pick, the Preen Garden Weed Preventer and Plant Food? Check product information carefully so you'll know which kind of formula you are getting, especially if you are using a non-selective formula and plan to introduce new plants into the area.

Type of Substance

When choosing a weed killer, it's important to ensure that the type is appropriate for the area where you wish to apply it and that the application method—concentrated, ready-to-use, or granule—is the best choice. If you lack a backpack sprayer or pump sprayer, you may want to avoid a concentrate. If you just have a few spots to hit, a ready-to-use spray is the easiest to use. Granules are perfect for large lawns, especially if you have a spreader handy.

Toxicity

Herbicides vary in toxicity. Glyphosate is one of the best-known weed killers and has recently been identified as harmful to our waterways and health. Some chemicals, such as vinegar, are natural but still harmful! It’s important to remember that herbicides are meant to destroy plant tissue, so always use caution when applying near non-targeted plants.

Plants to Avoid

Most herbicides meant for use in the lawn are selective, meaning they kill only weeds but not your grass. But you can still overdo it and burn your grass, so make sure you follow the label instructions. Certain grass species, such as St. Augustine, tend to be more susceptible than other grasses to herbicides, and many lawn products are not recommended for them. While weed identification is tough, knowing what you have helps.

FAQ
  • How does a weed killer work?

    Herbicides kill weeds by inhibiting root and shoot development or affecting foliage. Usually, pre-emergent herbicides work on newly germinated weed seeds underground to stop the normal development of root systems or prevent the plant from sending up new shoots. Post-emergent herbicides attack existing weeds.

    Some herbicides are non-selective, which means they kill all plants they encounter. (Round-Up, a glyphosate-based herbicide, is a widely available type of non-selective weed killer.) Most gardeners prefer selective weed killers, which affect only the growth of targeted species. They are used mostly for broadleaf weed control.

  • Are pets OK around weed killers?

    Many chemical weed killers have long-lasting residual effects on the applied-to areas. Pet owners should use caution when applying such products to places where their pets are likely to walk or lounge, since they could ingest the chemical directly or by licking their paws and fur.

    Organic weed killer may be a better option, since its compounds tend to break down more rapidly and are absorbed by the ground. However, it is still important to read the directions for use and consider the warning label on any products you use, since the potential effects can vary based on the active ingredients of each formula.

  • Are natural weed killers effective?

    Organic herbicides can succeed as weed killers. Formulas range from homemade solutions of distilled vinegar to ready-made products containing clove oil, citric acid, and other natural, active ingredients. Whether you use a homemade weed killer or purchase an organic herbicide, note that these products are non-selective. While some inorganic herbicides affect only specific invasive species, organic herbicides kill all plants within the application area.

  • How long can you expect a weed killer to remain effective?

    Time of efficacy varies by brand and concentration. Rainproof resistance is a key consideration, since you know that a little rain shouldn’t wash away the herbicide. Using pre- and post-emergent treatments is the best way to get a handle on year-round weed control, as you prevent weeds from starting and take care of those that present, so their seeds won’t persist.

Why Trust The Spruce?

This article was written by Amanda Rose Newton, a freelance writer and garden reviewer for The Spruce. As a certified horticulturist, she delighted in personally testing out the products to provide advice to those with different needs, yards, and priorities when it comes to weed control.
