Ingredients
Iron (FeHEDTA) is the active ingredient in Dandelion Doom. It's a selective broadleaf herbicide that targets weeds like dandelions, clover, and creeping charlie while leaving grass unharmed.
9-0-2 NPK blend in Sun and Shade Seed plus Feed delivers nitrogen for fast greening and potassium for stronger roots, with premium cool-season grass seed mixed in.
How to use
For best results, apply in spring or fall when temperatures are between 55 to 75 degrees F.
- Mix Dandelion Doom concentrate into the herbicide pouch and attach the battery-operated wand sprayer.
- Spot-treat visible weeds across your lawn, spraying leaves until covered. Avoid any areas you plan to seed.
- Wait 24 hours, then apply Sun and Shade Seed plus Feed evenly across your lawn at the recommended rate.
- Water thoroughly and keep soil consistently moist until seed germinates, typically 8 to 21 days.
- Reapply weed control as needed once new grass is established.

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.
