Ortho WeedClear Lawn Weed Killer Ready-to-Spray, 32 fl. oz. | Weed Killer Spray for Lawns, Kills Crabgrass, Dandelion and Clover, Hose-End Application, Covers 5,000 sq. ft.

My wife and I bought our first house together in March. 1/2 acre total, sandwiched close to two parks. Lot of animal and bird activity, therefore pollen. Started out with dandelions and clovers then mid summer got hit with a very fast crabgrass infestation. After treating all 3 with different products and at one point scorching my grass, let me share what I learned. The most important factor in fighting weeds that are blended in with grass is making sure it is safe for your grass type and do so by looking at the active ingredients. Second, use your smartphone camera and google search by photo your weed type. Many look identical but the key is some require different chemicals. For my application, this blend of quinclorac and 2,4D is perfect and the best part is it being less money than some other competitor’s products.

I had three trees taken down, and the areas were filling with weeds. I bought this to spray the weeds and other weeds in the yard, and it worked really well. Very easy to use by hooking it up to a hose.

This item killed my Clover and broadleaf weeds, but it didn't touch the crabgrass.

3-Star Review for Ortho WeedClear Lawn Weed Killer I picked up Ortho WeedClear Lawn Weed Killer to deal with a mix of weeds popping up in my lawn, and it’s been a decent experience, but not without flaws. The application was straightforward—mixing with a sprayer was easy, and it covered my medium-sized yard well. Within about 10 days, I saw noticeable results on dandelions and chickweed; they started wilting and didn’t come back, which was great. It also didn’t damage my grass, which is a plus since I’ve had issues with other products burning the lawn. That said, it wasn’t as effective on tougher weeds like thistles or creeping Charlie. I had to reapply a couple of times, and even then, some patches were stubborn. The bottle’s instructions were a bit vague on how long to wait between applications, which led to some guesswork. Also, the smell is pretty strong, so I had to keep my pets and kids off the lawn longer than I’d like. In summary, Ortho WeedClear works well for common weeds and is lawn-safe, but it struggles with more resilient types and requires patience. It’s a good middle-of-the-road option, but I might look for something more heavy-duty for persistent problems.

There is a comment about that says it does not kill crabgrass. Do not listen to that post because that’s what I use this for and have been using it for years to kill crabgrass. It’s pretty effective and has work very well for me. Crabgrass, clover, dandelion are specifically what I have always used this for and it will work for you. I do put it down with caution and wait until the early hours of the morning or a day when summer temps drop low for a day or two. It works.

this worked REALLY well against crabgrass. within a few days it started dying off. easy enough to apply too. I didn't have to mix chemicals in a sprayer which was nice.

Used this to kill the basic weeds in MO and one good coating and all the weeds haven't grown back. Been about a month and grass is still looking great.

Seemed mildly effective had to reapply a 2nd time
