Your grass stays, weeds don't

Dandelion Doom is an iron-based lawn safe weed killer for dandelions, clover, chickweed, and thistle. Weeds absorb too much iron and brown out. Your grass takes it in slowly and greens up instead. A post-emergent biopesticide, it handles visible weeds, not future ones. Build a Custom Lawn Plan for the full picture.

What makes Dandelion Doom different

Iron-based formula, no harsh chemicals
Visible results within hours of spraying
Your lawn stays green (actually gets greener)
Suppresses dollar spot, rust, and snow mold
Reusable pouch and sprayer for repeat use
EPA-registered biopesticide

Ingredients

The active ingredient is FeHEDTA, a chelated form of iron. It overwhelms broadleaf weeds while your grass absorbs it gradually and uses it as a nutrient. That is why weeds brown out and your lawn greens up.

How to use

Apply between 50 to 85 degrees F when no rain is expected for 3 or more hours.

Pour one full bottle of concentrate into the reusable pouch and attach the sprayer.
Fill pouch to the 1-gallon mark with your hose. Secure cap and shake well.
Spray onto weeds until all leaves are entirely covered.
Repeat in 3 to 4 weeks, or as needed. Store your sprayer and pouch for future use.

FAQ

When should I apply Dandelion Doom to my lawn?

Dandelion Doom works best when applied between 50 to 85 degrees F on a dry day with no rain expected for 3 or more hours.

The longer it sits on the weed leaves, the better. Spring and fall are the most common times to spray, when broadleaf weeds are actively growing.

Will Dandelion Doom damage my grass?

Dandelion Doom is a selective broadleaf herbicide, so it targets weeds while leaving grass alone.

Grass absorbs iron slowly and tolerates higher amounts. Weeds take in too much iron too quickly, which causes them to dry out. Your lawn may actually look greener after application.

What weeds does Dandelion Doom control?

Dandelion Doom controls broadleaf weeds including dandelions, clover, chickweed, thistle, creeping charlie, plantain, oxalis, and English daisy, plus moss, algae, and lichens.

It also suppresses lawn diseases like dollar spot, rust, and snow mold.

How long does Dandelion Doom take to work?

Dandelion Doom shows visible results on some weeds within hours of application.

Fully drenched weeds respond within 24 hours depending on the size and maturity of the plant. Repeat treatment every 3 to 4 weeks as needed.

Can I use Dandelion Doom with other Sunday products?

Dandelion Doom can be applied before or after lawn fertilizer. Let it dry completely before applying any other Sunday liquid products or watering.

For best results, plant Sunday grass seed a day after applying to fill in spots left by the weeds.

How is Dandelion Doom different from conventional broadleaf herbicides?

Dandelion Doom uses iron (FeHEDTA) as its active ingredient instead of the harsh chemicals found in conventional broadleaf treatments.

It is an EPA-registered biopesticide that controls weeds through iron overload rather than the harsh ingredients in conventional weed treatments.

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!

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

Hello Alec! Thank you for sharing your experience with us. We're glad to hear that our product helped control the weeds, and we look forward to providing even better results in the future.

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.
