FAQ

What weeds does Dandelion Doom kill?

Broadleaf weeds including dandelions, white clover, chickweed, creeping charlie, ground ivy, oxalis, and bull thistle. Also kills moss and algae. Does not control grassy weeds like crabgrass, for that try Weed Warrior.

Will it kill my grass?

No. The formula is selective. Broadleaf weeds absorb iron in a way that's toxic to them while your grass tolerates it. Works on all cool and warm season turf when used as directed. Apply within the 50 to 85°F window for best results.

How long does it take to work?

Visible wilting starts within hours on actively growing weeds. Full results within 1 to 2 weeks. Established weeds may need a second application 3 to 4 weeks later.

Can I use this on my whole lawn?

This formula is for spot treating individual weeds. For heavier weed pressure across a larger area, Dandelion Doom Concentrate with a wand sprayer is the more efficient choice. No sprayer? These bottles work across the whole lawn one spot at a time.

Is the 2-pack worth it over buying one bottle?

Weeds show up in spring and again in fall. Stubborn ones need a second round. One bottle rarely covers a full season. Two keeps you stocked without thinking about it.

Is it safe for kids and pets?

This is made from one active ingredient, iron. No harsh chemicals, ever. So people and pets can return to the area once the spray has dried.

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!

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/wan...

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.

Does not wprk!

Does not work! Applied on a sunny day. Says you'll see wilting in a few hours. Nope! Waited 2 days still nothing. No rain fell for 2 days. Applied again after rain. Still nothing and there are more danelions. Seems like a complete waste of money! Going back to ortho weed be gone

Sunday

We’re really sorry to hear this was your experience, and we appreciate you taking the time to share it. Dandelion Doom works best when sprayed directly on actively growing weeds with full leaf coverage, and some mature dandelions can take more than one application plus a little patience before showing results. Cooler temps, stressed weeds, or rain timing can also slow things down. We know stubborn dandelions can feel personally offensive this time of year, and we’d love the chance to help troubleshoot and get better results from your next application.

Kills the tops but not the root

From my experience I have used the Dandelion Doom for 2 years and it would work on the top of the weed but then it will not work on the root. The Plant would die and then grow back. I have gone to hand pulling the weeds and I am pulling up some dandelion with some very big and long tap roots. Too ba...

Sunday

Thanks for sharing your experience, and honestly, those deep dandelion taproots can feel like nature’s version of a prank. Dandelion Doom is designed to target the weed down to the root over time, but larger, established dandelions with mature taproots can sometimes survive and regrow, especially if they’ve had a few seasons to settle in like unwanted houseguests. Hand pulling combined with spot treatment is actually a really solid strategy for stubborn weeds like these. We appreciate you giving it a real shot for two seasons, and we’re always here to help troubleshoot so your lawn can spend less time battling dandelions and more time looking gloriously green.

Mixed Results

Dandelion Doom does seem to kill dandelions but it's a long, slow process. I sprayed a week ago and saw the dandelions start to wilt within hours. However, a week later, they're not dead yet and during the slow kill process, the dandelions have produced a lot of blooms that are going to seed, before...
