Our Top Picks

Our #1 Top Pick: Spectracide Weed & Grass Killer

The Spectracide Weed & Grass Killer is a powerhouse when it comes to tackling unwanted vegetation. Its fast-acting formula starts to destroy weeds and grasses to the root within hours. Easy to use, its spray bottle comes with a user-friendly trigger for precise application. Once applied, this formula becomes rainproof in just 15 minutes, ensuring that a sudden downpour won’t wash away your efforts. The Spectracide Weed & Grass Killer is perfect for use on driveways, walkways, and around fences, with visible results promised within 3 hours. However, note that this non-selective weed killer is potent and will kill any vegetation it contacts, so careful application is required.

Pick #2: Ortho GroundClear Vegetation Killer

Ortho GroundClear Vegetation Killer aims to not only eliminate weeds but to prevent new ones from emerging. This product is designed for both killing weeds and providing up to one year of prevention. The spray features a comfort wand for easy application over large areas. It’s ideal for creating clear zones on patios, driveways, and gravel areas. It’s important to note that this is another non-selective formula, which means it will kill any plants it touches, so users must apply it with caution.

Pick #3: Roundup Ready-To-Use Weed & Grass Killer III

Roundup is one of the most recognized names in weed control, and their Ready-To-Use Weed & Grass Killer III upholds that reputation. This easy-to-use product includes a convenient pump and go spray design, tailored for consumer ease and spot treatment. It is particularly effective for use around flower beds, trees, and shrubs, with the power to kill the toughest weeds down to the root. After application, it becomes rainproof in 10 minutes, and its formula is optimized for rapid results, with weeds starting to wilt and die within 24 hours of use.

Pick #4: Preen Garden Weed Preventer

Differing from the immediate weed killers, the Preen Garden Weed Preventer takes a proactive approach. It’s used to stop weeds from germinating in the first place, making it an ideal choice for those looking to maintain a weed-free space over long periods. Best applied after mulching, this weed preventer can be used around a vast range of flowers, vegetables, trees, and shrubs. It’s not suitable, however, for already-infested areas, as it will not kill existing weeds, but it’s an excellent preventive measure. Users will have to reapply it every few months for continuous protection.

Pick #5: Green Gobbler Vinegar Weed & Grass Killer

For those seeking an alternative to traditional chemical weed killers, Green Gobbler’s Vinegar Weed & Grass Killer offers a natural, organic solution.

What to Know Before You Buy

  • All-Purpose vs Selective: Some weed killers, known as non-selective herbicides, will kill any plant they contact. Selective herbicides, on the other hand, are designed to target specific types of weeds without harming other plants.
  • Contact vs Systemic: Contact weed killers will immediately affect the parts of the plant they touch, while systemic weed killers are absorbed by the plant and move through its system to completely kill it, taking longer to see full results.
  • Pre-Emergent vs Post-Emergent: Pre-emergent herbicides are applied to prevent weed seeds from germinating, while post-emergent herbicides are used to kill weeds that are already actively growing.
  • Environmental Safety: Some weed killers can be harmful to the environment. Look for products with a lower toxicity level or organic certifications if this is a concern for you.
  • Area of Application: Consider the area where you will be using the product. Some herbicides are specifically made for use around vegetable gardens, flower beds, or lawns, and choosing the wrong one can damage desirable plants.
  • Persistence: Check how long the weed killer remains active in the soil. Some products offer longer control against weeds while others might require frequent applications.

Factors to Consider Before Buying

  • Active Ingredients: Research the active ingredients in the weed killer. Glyphosate, for example, is a common and effective ingredient, but it’s also controversial due to its potential health risks. Consider alternatives if you prefer to avoid certain chemicals.
  • Ease of Use: Weed killers come in various forms including ready-to-use sprays, concentrates, and granules. Choose the one that you feel most comfortable handling and that suits your particular weeding needs.
  • Safety: If you have children or pets, look for pet-friendly and kid-safe weed killer options. Always read the label for safety precautions and follow them strictly.
  • Seasonality: Some weed killers are best applied during particular seasons. Make sure the one you choose is suitable for the current weather conditions and season.
  • Brand Reputation: Opt for brands with a consistent and positive reputation for effectiveness and customer satisfaction. Research reviews and ratings to inform your decision.
  • Budget: The cost of weed killers can vary widely. While you may not want to skimp and go for the cheapest option, it’s also unnecessary to overspend on features you don’t need.

Frequently Asked Questions

What is the best weed killer spray to use for large areas?

The best weed killer spray for large areas is usually a non-selective, systemic herbicide that can cover a large area efficiently. Products containing glyphosate are often recommended for their effectiveness in killing a wide range of weed species. Always make sure to follow the instructions on the label for the proper application.

Can I use weed killer spray in my vegetable garden?

Yes, but you must choose a product that is safe for use around edible plants. Look for weed killers labeled as safe for use in vegetable gardens, and always apply it according to the manufacturer’s instructions to ensure the safety of your food crops.

How long does it take for a weed killer spray to work?

The time it takes for a weed killer spray to work can vary depending on the product and the type of weeds being treated. Some products may show visible results within a few hours, while others might take several days to be effective. Systemic herbicides may require up to two weeks to fully kill the roots of the weeds.

Can I make a natural weed killer spray at home?

Yes, you can make a natural weed killer spray using common household ingredients like vinegar, salt, and dish soap. However, be aware that such homemade solutions may not be as effective as commercial herbicides and could also harm desired plants if not used carefully.

Is weed killer spray harmful to pets and children?

Some weed killer sprays can be harmful to pets and children if they are not used properly. Always look for pet-friendly and child-safe options if this is a concern. Regardless of the product, make sure to follow the safety precautions listed on the label, such as keeping pets and children away from treated areas until the product has dried or as instructed.

When is the best time to apply weed killer spray?

The best time to apply weed killer spray is typically during the spring and fall when weeds are actively growing. For best results, apply on a calm, dry day when rain is not expected for at least 24 hours to prevent wash-off. Early morning or late afternoon application can reduce the potential for herbicide evaporating too quickly in the heat of the day.

Will rain wash away the weed killer spray?

Rain can wash away the weed killer if it occurs soon after application. It’s best to apply herbicides when there is no rain forecast for at least 24 hours to ensure that the product has sufficient time to absorb into the plant’s system.

How often should I reapply weed killer spray?

This varies by product and the severity of the weed problem. Some products may provide control for several weeks or months, while others might require reapplication more frequently. Always consult the product label for specific reapplication intervals.

Are there any environmental concerns associated with using weed killer sprays?

Yes, there can be environmental concerns such as the potential for chemical runoff into waterways, the killing of non-target plants, and negative impacts on beneficial insects and soil health. It is important to use weed killers responsibly and to choose eco-friendly and sustainable options whenever possible.

What safety precautions should I take when using weed killer spray?

When using any weed killer spray, wear protective clothing, gloves, and eyewear to prevent exposure. Make sure the area is well-ventilated if you’re using it in confined spaces. Read and follow all instructions on the product label, and avoid direct contact with the spray.
