Ortho WeedClear Weed Killer for Lawns with Comfort Wand is designed to target and eliminate more than 250 common lawn weeds, including dandelion and clover, without damaging your lawn (when used as directed). Its formula contains three proven weed killers, ensuring effective root-level weed eradication. One of its significant advantages is the Comfort Wand applicator, which allows for precise, continuous spray control without the need for manual pumping, making it user-friendly and convenient.

Additionally, it produces visible results within hours and becomes rainproof just an hour after application, ensuring resilience against sudden weather changes. It's also safe for pets and children once the treated area has dried, adding an extra layer of reassurance for households with kids and animals. A potential drawback is the weight of the product, which is 9.4 pounds; handling and storage might be cumbersome for some users. The coverage area of 16,000 square feet is impressive for larger lawns but might be excessive for smaller yards.

It is a selective weed killer, which means it is effective on specific weeds but won't tackle all unwanted plants. This product is best suited for homeowners with medium to large lawns who need a reliable, easy-to-use weed killer that is safe for pets and children post-application.

Type of Weeds Targeted
Ortho GroundClear Weed and Grass Killer with Comfort Wand works amazingly well, easily eliminating stubborn weeds like dandelions and chickweed.
Application Method
The Comfort Wand makes application simple and precise, reducing strain while providing effective results.
Selective vs. Non-Selective
This herbicide is non-selective, meaning it can kill any plant it comes into contact with, so careful application is necessary.
Residual Activity
While labeled 'ground clear,' it only affects the plant tissue it contacts and has no soil activity, so it won't kill seeds in the ground.
Safety for Pets and Children
The product is generally safe for use around pets and children once dried, but caution is advised during application.

The Ortho GroundClear Weed & Grass Killer is a versatile and effective product for eliminating a wide range of weeds and grasses, including dandelions, chickweed, crabgrass, and moss. It is designed for use on patios, landscapes, walkways, and driveways, but not on lawns where you have desirable grass. The included Comfort Wand makes application easy and precise, ensuring you can target specific weeds without affecting nearby plants you want to keep.

One of the standout features is its fast action; you can see visible results within 15 minutes, and it's rainproof after just 2 hours of drying, making it convenient for varied weather conditions. However, users should apply it when weeds are small and actively growing for the best results, and it should not be used when the weeds are wet from rain or irrigation. The product is also OMRI Listed, indicating it meets organic standards, which is a plus for environmentally conscious users.

On the downside, this weed killer is non-selective, meaning it will kill any plant it comes into contact with, so careful application is necessary. Additionally, while effective, it may not offer the prolonged residual activity some users might prefer, requiring reapplication throughout the growing season. As for safety, it is generally regarded as safe for use around pets and children once dried, but caution is always advised during application. This product is ideal for homeowners looking for a quick, easy, and effective solution to weed control in non-lawn areas.

Ortho GroundClear Year Long Vegetation Killer1 Concentrate, Kills Weeds and Grasses, Prevents Unwanted Weeds and Grasses for up to 1 Year, 1 gal.

Rating
9.7
Type of Weeds Targeted

Most important from
14047 reviews

Type of Weeds Targeted
This product truly does work to kill weeds growing through rocks in the front yard.

The Ortho GroundClear Year Long Vegetation Killer1 Concentrate is designed to target both weeds and grasses, making it a versatile choice for various types of unwanted vegetation. It is a non-selective herbicide, meaning it will kill most plants it comes into contact with, so it is best used in areas where no plant growth is desired, such as driveways, sidewalks, and gravel areas. The product is easy to apply using a tank hose sprayer, which ensures even coverage and efficient use of the concentrate.

The instructions recommend mixing 24 fl. oz. of concentrate per gallon of water, and a single gallon of concentrate can treat up to 1,600 square feet, making it suitable for large areas. One of the key strengths of this product is its long-lasting effect, with the ability to prevent regrowth for up to a year. This makes it a convenient option for users who do not want to deal with frequent reapplications.

Additionally, it starts working immediately and kills weeds down to the root, ensuring thorough elimination. However, users should be aware that as a non-selective herbicide, it can harm desirable plants if they are accidentally sprayed. Also, its efficacy might be influenced by weather conditions, and it is not specifically indicated how rainfast it is. Safety for pets and children is another consideration; while the product does not specify particular safety measures, it is generally advisable to keep treated areas off-limits to pets and children until the product has dried and been fully absorbed.

Buying Guide for the Best Ortho Weed Killer

Choosing the right ortho-weed-killer can make a significant difference in maintaining a healthy and beautiful garden or lawn. The key is to understand the specific needs of your garden and the types of weeds you are dealing with. By focusing on the key specifications, you can select a product that effectively targets unwanted plants without harming your desired vegetation.
Type of Weeds TargetedThis specification indicates which types of weeds the product is designed to eliminate. It's important because different weed killers are formulated to target specific types of weeds, such as broadleaf weeds, grassy weeds, or sedges. To navigate this spec, identify the weeds present in your garden. If you have a mix of broadleaf and grassy weeds, look for a product labeled as 'broad-spectrum.' If you are dealing with a specific type, choose a product that targets that particular weed. Your need should guide you to select a weed killer that effectively addresses the weeds you are facing.
Application MethodThis refers to how the weed killer is applied, such as spray, granular, or concentrate. The application method is important because it affects ease of use and coverage. Sprays are convenient for spot treatments, granular products are good for large areas, and concentrates can be mixed for custom applications. To choose the right one, consider the size of the area you need to treat and your comfort with the application process. For small, targeted areas, a spray might be best. For larger lawns, granular or concentrate forms might be more efficient.
Selective vs. Non-SelectiveSelective weed killers target specific types of weeds without harming other plants, while non-selective weed killers will kill any plant they come into contact with. This is crucial because using the wrong type can damage your desired plants. If you need to protect your lawn or garden plants, opt for a selective weed killer. If you are clearing an area for new planting or dealing with a severe infestation, a non-selective product might be more appropriate. Your need to protect certain plants or clear an area will guide your choice.
RainfastnessRainfastness indicates how quickly the product becomes resistant to being washed away by rain. This is important because it affects the effectiveness of the weed killer after application. Products with shorter rainfast times are more convenient in areas with unpredictable weather. To navigate this spec, check the product label for rainfast times, which can range from a few hours to a full day. If you live in an area with frequent rain, choose a product with a shorter rainfast time to ensure it remains effective.
Residual ActivityResidual activity refers to how long the weed killer remains active in the soil after application. This is important for long-term weed control but can also affect future planting. Products with longer residual activity provide extended weed control but may prevent new plants from growing. To choose the right one, consider your future planting plans. If you plan to replant soon, opt for a product with minimal residual activity. If long-term control is your goal, a product with extended residual activity might be more suitable.
Safety for Pets and ChildrenThis specification indicates whether the product is safe to use around pets and children. It's important because some chemicals can be harmful if ingested or touched. To navigate this spec, look for labels that specify pet and child safety. If you have pets or children who play in the treated area, choose a product that is labeled as safe for them. Your need to ensure a safe environment for your family and pets will guide your choice.
