Dandelion Doom is an iron based lawn weed killer that targets dandelions, clover, chickweed, creeping charlie, and thistle without touching your grass. The iron powered formula overloads broadleaf weeds while making your lawn a deeper green. No harsh chemicals. This 2-pack includes concentrate, a reusable pouch, and a battery-powered wand sprayer. Pair it with Weed and Green or build a Custom Lawn Plan.
What makes Dandelion Doom Herbicide Concentrate Starter (2-pack) different
- Visible results on broadleaf weeds in hours
- Iron powered formula, no harsh chemicals
- Comes with a battery-powered wand sprayer
- Targets weeds without touching your grass
- Also controls moss, algae, and dollar spot
- Reusable pouch and sprayer for next time
Ingredients
Chelated Iron, FeHEDTA. A concentrated iron compound that broadleaf weeds absorb too quickly, causing them to dry out and brown. Grass absorbs it slowly and remains unaffected.
How to use
For best results, apply when temps are between 50 to 85 degrees F when no rain is expected for at least 3 hours.
- Pour one full bottle of Dandelion Doom concentrate into the reusable pouch and attach the sprayer.
- Use your outside hose to fill the pouch up to the 1 gallon mark. Secure the cap and shake well.
- Spray onto weeds in your lawn until all the leaves are entirely covered.
- Repeat treatment in 3 to 4 weeks, or as needed. Store your wand sprayer and pouch for future use.

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.

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.
Sunday

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.

Question: I sprayed Dandelion Doom yesterday on weeds and the grass where I sprayed is brown. IS this normal? THanks
Sunday
Good news, that browning is totally normal. Dandelion Doom works by targeting broadleaf weeds, so any brown you're seeing is just the weeds doing what we want them to do. If you sprayed it directly on your grass instead of just the weeds, your grass should bounce back in a few days without any lasting damage. If you've got any other questions about keeping those treated areas looking great, our yard expert Sunny can help you 24/7 at [email protected].

Question: Yard is full of dandelion and have to use that one spray pouch just won't work for the size of yard!
Sunday
For bigger areas, you’ll want something made for broadcast coverage like Weed & Green, which is designed to treat and help prevent broadleaf weeds across the whole lawn in one go: https://www.getsunday.com/shop/lawn-care/weed-green-liquid-weed-control Dandelion Doom is awesome for targeted hits, but for a yard-wide takeover, Weed & Green is the move. And if you want help dialing in the best game plan, we’ve got your back every step of the way

Question: Is this product safe for free ranging chickens?
Louisa D.
Great question! When using Sunday in an area where animals will be grazing, we recommend the following: 1. Apply Sunday only as directed according to your instructions and labels. 2. Wait 24 hours and then water the entire grass area with 1/2" of water, or wait until a rain before allowing animals back onto the grazing area.

Question: I have several weeds in my lawn, some dandelions, some creeping Charlie, clover, and others that I don’t even know what they are. I’m not sure what to do. Do you have a weed killer that I could attached to my hose and one that will kill all those weeds that I mentioned. I’m at a loss as to what to do. It’s a project. They have to tackle myself, which is not easy for a 79-year-old woman. Please let me know if you have any suggestions. Thank you
