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.

What's doing the work

  • Results in 20 minutes Fastest weed control in the Sunday lineup
  • Kills weeds, grass, moss, and algae Non-selective, kills all vegetation on contact
  • OMRI-listed for organic weed killer Approved for use in organic gardens
  • Non-staining formula Safe around bricks, concrete, and hardscapes
  • Two bottles, up to 100 sq. ft. One for spring, one for fall
  • Backed by our satisfaction guarantee

How to use

Apply between 50 and 85°F on a sunny day. Avoid rain for 3 hours after. Not for use in lawns.

  1. Shake bottle and adjust nozzle to desired spray pattern.
  2. Spray directly onto weed leaves until thoroughly covered.
  3. Repeat in 2 to 3 weeks for tough or established weeds.

People and pets can re-enter the area once the spray has dried.

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 violet! I highly recommend Weed Warrior for your weed control. Fred

    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!

    Sprayer handle is junk

    I’ve ordered the two pack twice. While the weed killer works Awsome. All 4 sprayer handles did not work. I only got one to kinda work the other 3 didn’t pump one ounce. I had to constantly shake the bag to get one to work They are absolute garbage.

    Sunday

    We're really sorry you got stuck with four broken sprayers when our weed killer is actually doing its job—that's inexcusable, especially when you've given us a second chance. We need to fix this for you with working sprayers or our pro sprayer so you can finally use the product that's actually working and get results without the frustration. Happy to help get another option in your hands!

    It Works!

    This weed killer has worked well for us. It's easy to use (but be careful to avoid the plants you want to keep) and it's more safe for our dog than the very toxic chemicals found in most weed treatments.

    Hello Rebecca! We're delighted to hear that our weed killer worked well for you. We look forward to helping you with any future gardening needs you may have. Thank you for choosing us!

    Not a permanent kill

    Weed warrior did kill the leaves of all the weeds and grass I sprayed within 3 hours just as advertised. However, within the week, the exact same weeds began growing right in the middle of the dead leaves! It seems the product does not kill the root permanently. These weeds were not large. Do I have to keep applying in order to kill the root? If so, I would need to purchase quite a bit more!!

    Thanks for sharing your experience. Weed Warrior works by burning back the top growth it contacts, but some weeds, especially perennial weeds, can regrow from roots or underground structures that weren't fully affected by the application. A follow up application may be needed for tougher weeds, but we'd love to help identify what's coming back. If you can share a photo of the weeds, our yard expert Sunny can take a closer look and recommend the best next steps. We’re here to help you get those weeds under control.

    Easy enough

    I like the ease of application. Was a little nervous about the possibility animals might tread on it before it dried, so I applied it at sundown. A word to those who said it doesnt work, be sure to shake it well before you use it.

    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 a second time where I had missed places, but it was still simple.

    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. The only thing I don’t love is the smell. I sprayed 12 hours ago and my backyard still stinks.

    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.
