9 Best Ortho Weed Killer 2025 in the United States

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 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.

Ortho GroundClear Weed & Grass Killer Super Concentrate is designed to tackle tough weeds and grasses with a fast-acting formula that works on contact and moves down to the roots for a thorough kill. Weeds start to wilt within hours and die completely in 1 to 2 weeks, providing quick results. It becomes rainfast just 15 minutes after application, so you don’t have to worry about losing effectiveness if it rains shortly after you spray. This product is a concentrate, meaning you need to mix it properly before use, which adds a small step compared to ready-to-use sprays.

It’s suitable for various outdoor areas like patios, walkways, and driveways, but since it kills on contact and targets roots, it’s non-selective and will harm any plants it touches, so be careful around flowers or grass you want to keep. The product should be applied when weeds are actively growing and temperatures are above 60°F for best results. Covering up to 2240 square feet per bottle, it offers good coverage for medium-sized areas.

This weed killer is effective for quickly eliminating unwanted weeds and grasses but requires careful handling and precise application to avoid damage to desirable plants and ensure safety.
