Your lawn deserves an iron-based weed killer

Dandelion Doom is a selective iron-based weed killer that targets dandelions, clover, chickweed, ground ivy, and moss without harming your grass. It handles visible weeds as a post-emergent spot treatment. One ingredient, no mixing, no harsh chemicals. Grab a bottle and get to work. For more weed coverage, try the Dandelion Doom Starter Pack.

What makes Dandelion Doom Ready-to-Use Weed Killer Spray different

  • Visible weed wilting starts within hours
  • Iron-based formula with no harsh chemicals
  • Ready to use with no mixing required
  • Works on all cool and warm season grasses
  • You can reseed just 1 day after applying

Ingredients

Chelated Iron (FeHEDTA) is absorbed rapidly, overloading broadleaf weeds causing them to dry out and die. Your grass absorbs the iron slowly, so it stays green and healthy.

How to use

Apply on a sunny day when temperatures are between 50 and 85 degrees F. Avoid spraying if rain is expected within 3 hours.

  1. Shake the bottle well and adjust the nozzle to your desired spray pattern.
  2. Spray directly onto weed leaves until they are fully covered.
  3. Let the product dry completely before foot or pet traffic on the treated area.
  4. Repeat in 3 to 4 weeks for stubborn or established weeds.

When should I use Dandelion Doom?

Dandelion Doom works best when weeds are actively growing and temperatures are between 50 and 85 degrees F.

Apply on a sunny day with no rain in the forecast for at least 3 hours. Spring and fall are the prime windows for broadleaf weed control.

How long does Dandelion Doom take to work?

Dandelion Doom starts wilting some broadleaf weeds within hours of application.

Full results, including root kill, typically appear within 1 to 2 weeks. Established weeds may need a second application 3 to 4 weeks later.

Will Dandelion Doom kill my grass?

Dandelion Doom is a selective weed killer, meaning it targets broadleaf weeds while leaving your grass unharmed.

It works on all cool and warm season grass types when used as directed. Grass absorbs iron more slowly than weeds, so your lawn stays green while weeds dry out.

Does Dandelion Doom stain concrete or sidewalks?

Dandelion Doom contains iron, which can stain hard surfaces like concrete, pavers, and sidewalks.

Avoid spraying on or near hard surfaces. If you accidentally spill, immediately dilute the area with water to reduce staining.

What weeds does Dandelion Doom kill?

Dandelion Doom controls broadleaf weeds including dandelions, clover, chickweed, creeping charlie, thistle, plantain, oxalis, knotweed, speedwell, and more.

It also controls moss, algae, and lichens, and suppresses lawn diseases like Dollar Spot, Rust, and Snow Mold.

What is the difference between the ready-to-use spray and the concentrate?

Dandelion Doom Ready-to-Use comes in pre-mixed spray bottles, ideal for spot treating individual weeds. No mixing, no assembly, just squeeze the trigger sprayer for fast weed control.

The concentrate covers more area and has an easier application style for larger lawns, but requires mixing with water and the Sunday Herbicide Pouch and Sprayer system to apply.

    Fast working and effective!

    I used the small wand with a pouch and sprayed each dandelion plant individually. Before spraying, my yard looked like my neighbors. 24 hours later, they are dying nicely!

    Disappointing clover results

    Very disappointing. I applied this multiple times exactly as directed, on both young and established clover, and it simply did not work. The clover is still there and looks completely unaffected. Glad I bought it on sale.

    Sunday

    We're really sorry to hear it didn't work as expected—that's frustrating. There could be a few factors at play (clover can be stubborn), and our yard experts would love to troubleshoot with you to make sure your next application actually works. Reach out to our team at [email protected] or chat with Sunny, our yard expert available 24/7, and we'll get your lawn back on track.

    Very effective and easy to use!

    I’ve bought this 3 or 4 times now and found it to be very effective against bitterchambers, clover and other broadleaf annoyances. They’re usually dead within. 24 hours. Unfortunately, the weeds keep coming back from my neighbors yard to mine but this product helps me stay on top of them. No issues using the bag and battery powered wand to apply it. My only thought would be I need a larger size for a larger lawn. Will buy again!

    Good product

    Works great. Have used it a couple years now on my southwest Florida lawn. Neighbors have the "snowball" and assortment of weeds- my lawn is all grass. I spot onto the specific weeds and walk the entire property. It kills about 90% of the varieties of weeds here in my hot humid area.

    Works ok, but weeds came back

    Used this in the spring and again in the summer. It managed to kill the weeds temporarily, but they came back.

    I give up after two sprayers

    Never could try the product: two sprayers in a row dead on arrival. Very frustrating. Also, do YOU feel it’s easy to find troubleshooting steps on your website? Set a timer, and ask a coworker to browse the site for instructions on how to test the Dandelion Doom product if it isn’t working.

    Sunday

    We're sorry to hear that. Two sprayers arriving unusable is incredibly frustrating, and we appreciate you letting us know. If you're willing to give it one more try, our support team can walk you through a few quick troubleshooting steps, like checking that the hose is fully tightened, the sprayer dial is set correctly, and the water is turned on before replacing the sprayer if needed. We're here to help get you up and running. And we'll spend some time adjusting our videos to ensure they are easy to find!

    Quality control needs work

    The herbicide is decent. Not great, but decent. My bigger complaint is that 3 of the bag/wand combos have leaked excessively - cost me time and money. The first time it happened, made huge mess in my garage. I learned my lesson, cleaned it all up, and put the equipment in a plastic bin. Next bag/wand leaked again and ruined the wand this time. Sunday replaced it, but now it's happened a third time. Went to grab my herbicide and it wouldn't work, bin was filled with liquid, battery shorted out. Done with this. I love Sunday in theory, the execution leaves much to be desired.

    Sunday

    Hi Adam, we are so sorry — three leaks is not a streak of bad luck, it's a pattern, and we own that completely. You did everything right: you cleaned up the first mess, took precautions with a bin, and gave us another chance after we replaced your wand. Having that battery short out after all of that is genuinely unacceptable, and we're embarrassed it came to this. We've flagging this as a quality issue with our R&D team. Your feedback on the Dandelion Doom 2-pack is exactly the kind of thing that needs to reach them. We have refunded you for your pouch and sprayer. You've been more patient with us than we deserved, and we don't take that lightly. Thank you for sticking with Sunday as long as you have.

    Dandelion weed killer doesn't work

    I followed the instructions and sprayed each dandelion in my front and back yard, nothing happened. Dandelions are just as healthy as they were before. some of my grass died around the dandelions though, so it may be a good grass killer.

    Sunday

    Hi Ken, thank you for sharing this, we're really sorry to hear about your experience, and we want to get to the bottom of it. A couple of things can affect how our weed control performs on dandelions: -Temperature at application: Our formula works best when temps are between 50–90°F. Applications in heat over 90°F or during cooler stretches can reduce effectiveness. - Dandelion growth stage: Dandelions are hardiest when they're flowering. Spraying when they're young and actively growing (pre-flower) tends to get the best results. - Coverage: Dandelion leaves have a waxy coating, so thorough coverage on the tops *and* undersides of the leaves is key. We'd love to make this right. Please reach out to us at [email protected] and we'll work with you on next steps!

    Works for me!

    It works for me. I also pick off every flower before it even fully blooms to prevent more seeds. I use it in my front yard only, and you can really tell the difference. I spot treat, rather than spray the whole lawn.

    Followed direction perfectly. Nothing. Dandelions never died, still growing. Will switch to a different brand for weed control

    Sunday

    We're sorry to hear that and appreciate you taking the time to share your experience. Dandelions can be especially stubborn, and factors like weed maturity, application timing, and weather conditions can affect results. We'd love to learn more about your lawn and application so we can help troubleshoot. Our team is always happy to take a closer look and help you get the most from your products.
