This ensures that only the weeds are affected while leaving the grass unharmed when applied as directed.

The product features a convenient Comfort Wand applicator, making it easy to apply with precision and without the need for pumping. This user-friendly feature can save time and effort during application. Additionally, the product promises visible results within hours and becomes rainproof after just one hour of drying, allowing for quick and effective weed control even in unpredictable weather conditions. It also covers a substantial area of up to 16,000 square feet, making it suitable for larger lawns.

At 9.4 pounds, it may be a bit cumbersome to handle for some users. Additionally, as with any herbicide, improper application can lead to unintended damage to the lawn, so careful adherence to instructions is essential. Ortho WeedClear Weed Killer is a reliable option for those seeking an effective solution to weed problems without compromising the health of their grass.

Additionally, while it is effective on listed Northern grasses like Kentucky Bluegrass and Perennial Ryegrass, it may not be suitable for other grass types or regions.

Users can start to see visual results anywhere from 1 to 6 weeks after application, which provides a broad timeline but might require some patience.

One major advantage is its rainproof protection, which kicks in after just 4 hours, so there's less worry about weather conditions impacting its effectiveness right after application. With a liquid volume of 128 fluid ounces, the product offers substantial coverage, making it suitable for larger areas infested with various weeds and brush. The ready-to-use spray form simplifies the application process, eliminating the need for any mixing or additional preparation.

However, it's worth noting that while the product is highly effective against a range of tough weeds, it is not explicitly mentioned that it won't harm grass.
