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.

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.

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

FAQ

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.
