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.

FAQ

When is the best time to apply Dandelion Doom?

Dandelion Doom Herbicide Concentrate works best when temperatures are between 50 to 85 degrees F with no rain expected for 3 or more hours. Spray when weeds are actively growing for the strongest results.

Will Dandelion Doom hurt my grass?

Dandelion Doom Herbicide Concentrate targets broadleaf weeds, not grass. Grass absorbs iron slowly and uses it as a nutrient, so your lawn may actually look greener after application. Some temporary dark discoloration is normal.

What weeds does Dandelion Doom control?

Dandelion Doom Herbicide Concentrate controls broadleaf weeds including dandelions, clover, chickweed, creeping charlie, thistle, plantain, oxalis, and speedwell. It also controls moss, algae, lichens, and suppresses lawn diseases like dollar spot and rust.

How long does Dandelion Doom take to work?

Dandelion Doom Herbicide Concentrate shows visible results within hours of application. Fully drenched weeds will dry up within 24 hours depending on the size and maturity of the plant. Repeat treatment in 3 to 4 weeks if needed.

How does iron based weed control work on lawns?

Dandelion Doom Herbicide Concentrate uses iron (FeHEDTA) to overload broadleaf weeds. Weeds absorb the iron too quickly and it becomes toxic. Grass absorbs the iron slowly and tolerates higher amounts, so it stays healthy.

Can I use Dandelion Doom with other Sunday lawn products?

Yes! Dandelion Doom Herbicide Concentrate can be applied before or after lawn fertilizer. Let the weed control dry completely before applying other Sunday liquid products or watering your lawn. The longer it sits on the leaves, the more effective it is.

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.
