Helpful Tips from Lawn Advisors:

How does weed and grass killer work?

Weed Warrior is a powerful herbicidal soap made from fatty acids. It eats away at the waxy coating that protects most green leafy growth from the elements, causing rapid desiccation and plant death.

What vegetation does Weed Warrior control?

Effective against bluegrass, chickweed, crabgrass, corn spurry, dandelion, groundsel, lambsquarters, mouse-eared chickweed, mustards, plantain, redroot pigweed, round leaved mallow, sheep sorrel, shepherd's-purse, stinkweed, thistle, moss, algae, and lichens.

Do I need the Weed Warrior Starter Pack to use this product?

Yes, this is a refill concentrate only. You'll need the sprayer and pouch that come with the Weed Warrior Starter Pack or Starter 2-Pack to apply this product.

How many applications will I get from this 2-pack?

Each bottle treats up to 224 sq. ft., so the 2-pack provides enough concentrate for two separate applications at this coverage, or one application over a larger 448 sq. ft. area.

Can I use weed and grass killer on my lawn?

Weed Warrior is non-selective, meaning it will kill any vegetation it contacts - including grass. We recommend using it in gardens, sidewalks, mulch and other hardscapes rather than within your lawn. If you use Weed Warrior within your lawn, repair it with Sunday Grass Seed or Bare Repair (https://www.getsunday.com/shop/category/lawn-care/grass-seed).

How long does concentrate last?

Concentrates have a shelf life of approximately 2 years. After the initial mixing, mix well again if it sits for 30+ days.

Are there any US states where this is not approved for use?

This product is approved for use in all states.

Bye bye grass in flowerbeds

So the new flowerbed had some Bermuda grass coming up through the weed guard paper, not any more. I watched it get wilty within 30 minutes when I went to check on it. I pulled the dead grass the next morning. Other weeds I hit in the flowerbed where much easier to pull then weeds I didn’t hit with w...

Didn’t work

I used this product on a number of weeds, twice. The weeds still live and this product didn’t touch them, I had high hopes for this product, however, it did not work for me.

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.

This product should be renamed!

It's called Weed Warrior. It should be called Vegetation Killer! It kills everything! I asked the support will it kill my grass too? "Our herbicide killer is specifically designed to target unwanted grass with direct application. Rest assured, it is highly unlikely to harm your existing grass." Not ...

DID ABSOLUTELY NOTHING ☹️

I really wanted to like Sunday Weed Warrior because of it not having dangerous chemicals and being more natural alternative to traditional weed spray. However, I use this multiple times on my weeds and they didn’t even wilt a bit. It’s almost as if it fed them vs. killed them. They continued to grow...

I was totally amazed at

I was totally amazed at how fast the results revealed how it works. Sprayed at noon and by 4 pm it was obvious to me the weeds were done. Sunday said it was quick - it was faster than that!

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!
