Twenty minutes from spray to dead weed

Weed Warrior is a ready-to-use organic weed and grass killer that starts working on contact. Spray it on and you'll see visible results in as little as 20 minutes. No synthetic chemicals, no mixing, no setup.

The herbicidal soap formula breaks down the protective coating on weeds, causing rapid die-off. It kills everything it touches, so it's built for flower beds, garden borders, driveways, patios, and mulched areas. Not for use in lawns.

Two bottles keeps you stocked for spring cleanup and fall maintenance without a reorder.

FAQ

Will Weed Warrior kill my grass?

Yes. Weed Warrior is non-selective, meaning it kills all vegetation it contacts including grass. Use it in flower beds, along driveways, around patios, and in mulched areas. Avoid spraying on grass you want to keep. For weed control in lawns, Dandelion Doom is selective and leaves grass untouched.

What's the difference between Weed Warrior and Dandelion Doom?

Two different jobs. Weed Warrior is non-selective and kills all vegetation on contact, grass included. Use it in beds, hardscapes, and borders. Dandelion Doom is selective and kills broadleaf weeds while leaving your grass alone. Use it in lawns. If you're not sure which to reach for, ask yourself: is there grass nearby you want to keep?

What does Weed Warrior kill?

Annual bluegrass, chickweed, crabgrass, dandelion, groundsel, lambsquarters, plantain, pigweed, sheep sorrel, shepherd's-purse, thistle, moss, algae, lichens, and more. Because it's non-selective, it will also kill any desired plants it contacts. Apply carefully around flowers, shrubs, and anything you want to keep.

Can I use Weed Warrior in flower beds?

Yes, of course. Weed Warrior is safe to use around ornamental flowers, mature shrubs, and trees as a spot treatment. Apply directly to weed leaves, avoiding spraying desirable plants. Works well in bark mulch, raised beds, and planters before planting.

How long does it take to work?

Visible results in as little as 20 minutes. Fully drenched weeds die within 24 hours. Older or more established weeds may need a second application 2 to 3 weeks later.

Is it safe for kids and pets?

This contains one active ingredient: herbicidal soap. No glyphosate, no harsh chemicals. So people and pets can return to the area once the spray has dried.

Weed Warrior Recommendation

I've used Weed Warrior on my toughest weed (purple violet) and on persistent weeds that grow in the cracks of our driveway. Within hours, the weeds are dead and so is my grass (the label clearly states it will kill grass too). Patching the small amount of grass is worth it to get rid of the purple v...

This stuff WORKS!

I love my Sunday weed warrior! I like that the weed killer works and doesn't kill my grass. Plus I don't have to worry about harmful chemicals and feel good letting my dog/neighbor kids run around on the grass after it's dry. Sunday fan for life!

The solution for environmentally aware yards

Great product. We have a creek alongside our yard and don’t use herbicides unless absolutely necessary. Weed Warrior did an excellent job on a large lawn rehab, taking out tons of crabgrass and mock strawberry I had struggled with for years, so we can overseed with the Sunday shade mix. I went back ...

Weed warrior kills weeds

I think this stuff works great. My weeds were awful this spring and I wish I tried this sooner. If it isn’t working for you, I think you might not be following the instructions. Make sure you’re shooting the leaves and not going for the roots. I think the sun also plays a role in the success. Th...

This stuff works FAST!

I don’t know what any of these people are talking about who say this stuff doesn’t work. I sprayed this on crab grass and weeds and everything. It’s all dead in less than 12 hours.

Great for dandelions

My experience is that it works great for dandelions but doesn’t do anything for other weeds.

So much crab grass

Weed warrior did nothing for me. I have so much crabgrass. I have never had this much. Will not be renewing Sunday this had not been a good experience.

We're sorry to hear that your weed control results aren't as expected! Here are some Best Practices to follow for best results. 1.) Try to apply on a sunny day. While not mandatory, sunshine will improve the efficacy and speed of our herbicides. With sunshine unfiltered by clouds, our herbicides will work even better. A rainfall within 3 hours after application can make the herbicides ineffective. Optimal temperatures for application are between 50F to 85F. 2.) Apply when the weeds look healthy. When weeds are stressed or injured, weeds release hormones to recover. These hormones make herbicides less effective. Hormones are also released if weeds are mowed; we recommend not applying on the same day you mow. 3.) Apply the leaves liberally. Our herbicides just need to make contact with the leaves to work; trying to apply to the roots won't be effective. For best results, you want the leaves soaked, but not to the point where the herbicides is dripping off the leaves. 4.) Know the age of the weed. Older and established weeds will likely require more applications. For older weeds, we recommend doing multiple applications on the same day; just let the leaves dry out in-between applications.

Amazing

The 2024 spring season in Wisconsin met us with a lot of rain. Between juggling work/ family/ animal needs we just could not stay on top of the weeds in our many flower beds. We have dogs, chickens, outdoor koi and two bee hives on our land- so having something "safer" was necessary. We tried the da...

No impact at all

Sprayed this product on weeds and no impact. My initial thought was rains the next day impacted the application so used a second round on a hot day with no rain. Again, absolutely no impact on any of the weeds sprayed. Very dissatisfied with this product.
