We tried Ortho WeedClear on our stubborn lawn weeds. It mostly did the trick without harming the grass, which is always a relief.
Setting it up with the hose sprayer was a breeze. We noticed some weeds starting to die within a day or two.
It seems to work best when weeds are small and actively growing, which lines up with our spring garden routine. If you’re tackling a jungle, you might not see miracles overnight.
While it cleared out dandelions and clover pretty well, tougher weeds stuck around a bit longer. Just a heads-up: following the instructions closely is important if you don’t want to risk damaging your lawn.
Bottom Line
If you want a straightforward weed killer that works fast and doesn’t wreck your grass, Ortho WeedClear seems worth a shot. It’s simple to use and handles a lot of weed types.
Overview: Ortho WeedClear Weed Killer for Lawns Ready-to-Spray
We found this weed killer easy to use thanks to its hose sprayer attachment. It targets common weeds like dandelions and clover but leaves the grass alone if you apply it correctly.
Results started showing within a few hours, which felt pretty satisfying. The product covers a large area, so it’s handy for bigger lawns.
For tougher weeds, we had to wait a week or two for them to disappear. One thing: if you’re treating a huge yard, it can get a bit pricey.
Key Features
When we’re fighting weeds, we want something that works but doesn’t trash the grass we’ve worked hard to grow. This product stands out because it balances weed control and lawn safety in a ready-to-use form.
Kills Over 250 Common Weeds
We found it effective against a bunch of weeds—over 250 kinds, apparently. It handled dandelions and clover, but also less common stuff like poison ivy and chickweed.
This broad coverage makes it pretty versatile, especially if your yard’s a bit wild.
Won’t Harm Grass (When Used as Directed)
We liked that our grass stayed healthy after using it. The formula uses three active ingredients that focus on weeds, not lawn grass.
Apply it carefully, though. It’s easy to slip up and get some brown patches if you aren’t paying attention.
Visible Results in Hours
We saw changes quickly after spraying—within a few hours, weeds started to look rough. That’s always reassuring and lets you move on to other yard work without second-guessing.
Rainproof Protection Within One Hour
It becomes rainproof after about an hour. That’s pretty handy if you’re dodging spring showers.
As long as you let it dry for that hour, you don’t need to stress if it rains. Saves some hassle and rework.
| Feature | What We Noticed |
|---|---|
| Weed Variety Covered | Over 250 types, including common and tricky ones |
| Lawn Safety | Grass stayed healthy when used right |
| Speed of Results | Weed damage visible within hours |
| Rain Resistance | Effective even if it rains after drying for 1 hour |
Pros and Cons
After giving this weed killer a go, we noticed some clear strengths and a few things to watch for.
Pros
- Effective weed control: We saw dandelions and clover start wilting within a day or two. It works on a variety of common lawn weeds.
- Lawn-safe formula: Used as directed, it didn’t harm our grass, which is huge for keeping a nice lawn.
- Easy application: The ready-to-spray design made it simple to connect to a hose and cover big areas fast.
- Quick drying: It dried within an hour, so pets and kids could go back outside soon after.
- Two-pack value: Comes with two bottles, which covers a decent yard without refilling.
Cons
- Takes time for full effect: Some weeds needed up to two weeks to die off. Patience required.
- Coverage cost: If you have a big lawn, it might not feel super economical.
- Requires careful use: You really do need to follow directions or you risk harming grass or other nearby plants.
- Limited to visible spraying: Only the treated areas get hit, so you might need repeat passes for dense patches.
| Pros | Cons |
|---|---|
| Works on many weed types | Slow full weed death |
| Safe for lawn | May be costly for large yards |
| Simple hose attachment | Must follow directions closely |
| Fast drying and pet-safe | Only affects sprayed spots |
| Two bottles included |
Ease of Use
Applying the weed killer was straightforward. The ready-to-spray design meant we didn’t have to mix anything—nice and simple.
The spray nozzle gave us good control, so we could target specific spots and avoid hitting the grass. We had to wait for results, though; some weeds took up to two weeks to finally die.
Following the instructions was key to avoiding damage. It’s not totally foolproof, but it’s not rocket science either.
Pros:
- No mixing needed
- Simple spray application
- Good control over coverage
Cons:
- Takes time to see full effects
- Must be used carefully to protect grass
Coverage and Value
Two 32 oz. bottles cover up to 16,000 sq. ft., which is decent for small to medium yards. If you’ve got a larger lawn, you’ll probably need more, and that adds up.
It works on a bunch of weeds and doesn’t harm the grass if you use it right. Some of us noticed it takes several days for all the weeds to die, so don’t expect instant results.
The price feels fair for what you get, but if you want lightning-fast results on a massive yard, it might feel a little slow and expensive.
