Your organic alternative, in a refill

Weed Warrior Concentrate Refill is a glyphosate-free organic weed and grass killer made from herbicidal soap. It strips the waxy coating off dandelions, crabgrass, chickweed, thistle, and plantain, with visible results in 20 minutes. Heads up, it kills grass too, so stick to driveways, patios, sidewalks, garden beds, and between pavers. For in-lawn weeds, grab Dandelion Doom.

What makes Weed Warrior Weed & Grass Killer Concentrate Refill different

  • Visible results in as little as 20 minutes
  • Glyphosate-free and OMRI-listed organic
  • Non-staining formula for patios and pavers
  • Works with your reusable Sunday sprayer
  • Works on 18+ weeds, moss, algae, and lichens

Ingredients

Herbicidal soap made from fatty acids. It breaks down the waxy outer layer on leaves, causing weeds to lose moisture and dry out rapidly.

How to use

Apply when temperatures are between 50 and 85 degrees F and no rain is expected for at least 3 hours.

  1. Pour the concentrate into your reusable Sunday pouch.
  2. Fill the pouch with water to the 1 gallon mark.
  3. Shake the pouch well to mix.
  4. Spray until leaves are entirely covered, top and bottom.
  5. Repeat in 2 to 3 weeks for any regrowth.

Will Weed Warrior kill my grass?

Weed Warrior Weed & Grass Killer Concentrate Refill is a non-selective herbicide, meaning it will kill any vegetation it contacts, including grass. Use Weed Warrior on driveways, patios, sidewalks, garden beds, and mulched areas.

For weeds growing in your lawn, use Dandelion Doom instead.

How fast does Weed Warrior work?

Weed Warrior Concentrate Refill delivers visible results in as little as 20 minutes. The herbicidal soap strips the waxy coating off leaves, causing weeds to dry out and brown on contact.

For tougher weeds with deep roots, repeat the application in 2 to 3 weeks.

What is the difference between Weed Warrior and Dandelion Doom?

Weed Warrior Concentrate Refill is non-selective, meaning it eliminates all vegetation on contact. Use it on patios, driveways, and garden beds. Dandelion Doom is selective and targets broadleaf weeds like dandelions and clover while leaving grass unharmed.

Is Weed Warrior a good alternative to Roundup?

Weed Warrior Concentrate Refill is a glyphosate-free, OMRI-listed organic weed and grass killer. It uses herbicidal soap from fatty acids instead of glyphosate. You can see weeds brown and wilt within 20 minutes of application, with no harsh chemicals.

Do I need the starter pack to use this refill?

Weed Warrior Concentrate Refill requires the Sunday reusable pouch and wand sprayer to apply. If you do not already have the sprayer system, pick up a [Herbicide Pouch + Sprayer](https://www.getsunday.com/shop/lawn-care/sunday-weed-killer-pouch-and-sprayer) or a Weed Warrior Starter Pack.

How long does Weed Warrior concentrate last?

Weed Warrior Concentrate Refill has a shelf life of approximately 2 years. After the initial mixing, shake the pouch well again if it sits for 30 or more days before the next use.

It works on many weeds

It works on many weeds but doesn't work as well on clover. I know it's sprayed on 1 weed at a time and maybe I missed some. I find that a solution attached to a hose and sprays provides better coverage

Well, it's August, the month

Well, it's August, the month I was waiting for to really put Sunday to the test. By now, the lawn is usually withered and full of crab grass. Thanks to the great instruction AND the very effective products. I'm in the green in August for the first time in 20 years!

I like the idea of

I like the idea of less chemicals and more natural ingredients. Unfortunately, this just does not do the job. I will stick with the fertilizers, but continue to use the top name brands for weed killers.

Fit for purpose

I have a gravel driveway that was swimming in weeds. I tried vinegar on them, but it made only a tiny dent in the problem. This works so much better. In combination with a Dutch hoe, the driveway is finally clear. Don’t expect Roundup like results, but I’m trying to stay away from that stuff. Also...

Weed Warrior.....

Weed Warrior is marginally effective at best in my experience. It does not work on all weeds and is not a permanent fix.
