Ortho WeedClear Weed Killer for Lawns Ready-To-Spray - Won't Harm Grass (When Used as Directed), Weed Killer Spray, Kills Dandelion & Clover, Treats up to 16,000 sq. ft., 32 fl. oz.

I recently used the Ortho WeedClear Ready-To-Spray on my lawn and was honestly impressed. Here are the highlights from my experience: Effectiveness: It did exactly what it claimed to do. It targeted the weeds without harming my grass, and I saw them starting to wither pretty quickly. Coverage: My lot is about a half-acre, and one bottle managed to cover almost the entire lawn. For a "Ready-To-Spray" product, that’s great efficiency. Ease of Use: The hook-up to the hose was seamless with no leaks, which made the application go much faster than using a manual pump sprayer. Bottom Line: If you have a larger lot and want something that is effective and easy to apply, this is a solid choice. I'll definitely be keeping this in my lawn care rotation.

Dollar weeds coming up throughout my front yard. One application as directed took care of the weeds.

I see two types of complaints on this product - #1: Takes multiple treatments to work #2: Weeds come back in weeks. The answer can be found on the product label. It claims to treat 8,000 square feet for "Northern Lawns" and 16,000 square feet for "Southern Lawns". Well, that makes absolutely ZERO sense to me. I doubt the product will ever treat more than 8,000 square feet. How would a spray-bottle fed system last twice as long when there is no alternative direction for "Southern Lawn" application? It simply says spray until grass is wet. There is no separate instruction for "Southern Lawns", so how could the same 32 oz last twice as long? Obviously, that is logically impossible. I believe people who live in the south and attempt to make the 32oz bottle last for 16,000 square feet are under-treating their lawns and thus must re-apply this product again in a few weeks if they do not want weeds to re-appear. Try using it on a 90 x 90 foot piece of yard with one treatment of the entire bottle and see how it does. i suspect no re-application would be necessary.

This product is a rip off. I used 4 containers for my house yard (front and back) and not a single weed died. The lot is only 6,000 sq feet so there is no excuse. I ended up killing the weeds by purchasing vinegar from Homedepot.

I even over sprayed my 5,000 sq. ft. area just a little but it did not kill the main weed that I was spraying for.

I recently tried the Ortho WeedClear Weed Killer for Lawns Ready-To-Spray, and I must say I am highly impressed with the results. As someone who takes great pride in maintaining a lush and weed-free lawn, this product has proven to be a game-changer in my lawn care routine. The convenience of the Ready-To-Spray formula is a major selling point for me. It eliminates the need for mixing or measuring, making application quick and easy. I simply attached it to my garden hose and sprayed the product evenly over my lawn, covering up to 16,000 square feet with one application. What sets the Ortho WeedClear Weed Killer apart is its effectiveness. It targets a wide range of common lawn weeds, including dandelions, clover, and crabgrass, while leaving my grass unharmed. Within days of application, I noticed a significant reduction in the presence of weeds, with most of them wilting and dying off completely. I appreciate that this product is rainproof within hours of application, ensuring that it remains effective even if it rains shortly after treatment. Additionally, the long-lasting results mean that I can enjoy a weed-free lawn for an extended period before needing to reapply. Overall, I highly recommend the Ortho WeedClear Weed Killer for Lawns Ready-To-Spray to anyone looking for a reliable and efficient solution to weed control in their lawn. It is a convenient, effective, and long-lasting product that delivers on its promises, helping me achieve the beautiful and healthy lawn I desire.

I’ve had St. Augustine grass for years, and if you own it, you know the fear: almost every weed killer on the shelf says “safe for southern lawns”… followed by a warning that excludes St. Augustine. I spent several seasons watching weeds take over because I refused to risk a product that might scorch‑earth the turf. This spring I found Ortho WeedClear, and it’s the first product I’ve seen that clearly states safe for St. Augustine. I didn’t take that claim lightly. I dug into the details, including the Floratam issue. (For anyone reading: Floratam is a Florida‑specific cultivar that is sensitive to certain herbicides. I confirmed through a bit of lawn forensics that my grass is a cold‑tolerant Georgia type — not Floratam — so WeedClear is appropriate for my yard.) Once I verified that, I tried it. WeedClear worked exactly as advertised. The weeds collapsed, browned out, and laid down, and the St. Augustine didn’t show any burn or stress. If anything, the product is on the gentle side — which is exactly what you want with this grass. The layer of weed thatch left behind showed just how badly the turf had been smothered. It wasn’t weak; it was buried. Now that the weeds are gone, the lawn finally has room to breathe again. I’m already seeing runners waking up and color returning. For the first time in years, the yard looks like it has a real path to recovery instead of slow decline. If you’ve been afraid to treat your St. Augustine because everything else feels like a gamble, Ortho WeedClear is the first product I’ve used that delivers on the promise without putting the turf at risk. I wish this had existed years ago. WeedClear didn’t just kill weeds — it gave my lawn a second chance.
