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.

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

Can I use weed and grass killer on my lawn?

Weed Warrior is non-selective, meaning it will kill any unwanted vegetation - weeds and 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 bare patches with Sunday grass seed or Bare Repair.

How to use Weed Warrior with other Sunday products?

You can apply weed killer, like Weed Warrior, before or after lawn fertilizer.

Allow weed control products to dry completely before applying any other Sunday liquid products or watering your lawn–the longer the plant absorbs the weed control, the more effective the application.

When will I see results?

Fully drenched weeds will dry up in as little as 20 minutes or up to 24 hours, depending on the size and maturity of the plant you are spraying.

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

This product is approved for use in all states.

    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.
