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.

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...

Product Works Great

I used this product on dozens of weeds we had and they were all dead by the next day. The downside was that after some rain, a few days later many other weeds had grown in their place. I need something to spray this on my entire lawn.

Didn't work :(

I used an entire bottle spraying each dandelion plant in our yard and none of them died!!!!

Sunday

Hello K, Ugh, that’s frustrating—we’d expect at least some dandelion drama after a full bottle. Most likely the spray didn’t fully absorb (waxy leaves can be sneaky), so try reapplying on a warm, dry day and really coat the leaves, not just the flower. If they’re still standing proud, Sunny (our yard expert) can help dial in the approach for your exact lawn so we can finally evict those freeloaders

Mixed results. Some great, some just ok.

worked like a CHARM last year. This year seems to be more of a challenge. Also when I used iron boost last year, it seemed to somehow prevent almost all the dandelions from blooming. The ones that did bloom last year were zapped right away with the dandelion killer. This year maybe I was late to spr...

Dandelion boom…

After emptying 4 gallons on hundreds of dandelions, I’m here to report that not even one died. This product is like dumping water on them.

Sunday

Hi Stephen, I'm sorry to hear about your experience with our product. That’s frustrating, and definitely not the result we’re going for. Dandelion control works best when sprayed directly on the leaves on a warm, sunny day so the formula can fully absorb and do its thing. If you’re up for it, our yard advisors can help troubleshoot and get those weeds waving the white flag—we’ve got your back

Kills grass

I tried this on my lawn o. Clover and other leafy weeds, but it killed my burmuda grass as well and didn’t do a great job on the actual weeds.

Sunday

Hello Allison, we're sorry to hear that, that’s definitely frustrating when your grass takes a hit and the weeds stick around. Dandelion Doom is designed to target broadleaf weeds without harming turf, but Bermuda grass can sometimes be more sensitive, especially in heat or if the lawn is already stressed. In the meantime, watering the lawn deeply but infrequently can help your grass recover and strengthen roots. We’re here to help you get things back on track and dial in the right approach for your lawn.

Didn't work

I really wanted this to work. I took a picture of the plants I was having problems with and this was the recommendation I got. I've applied both bottles, saturating all of the weeds. The bottle says you should see results in a few hours, but 24 hours later and everything is still doing fine, even th...

Sunday

Hi Nick, I'm sorry to hear that our product didn't meet your expectations. We really appreciate you giving it a shot—and sharing the details here. Dandelion Doom should start showing visible changes within a day, especially on true dandelions, so if everything looks untouched after 24 hours, that’s not the experience we want you to have. A couple factors like weed type, maturity, and coverage can impact results—but even then, you should be seeing something. Glad to hear your grass is doing okay—that part matters too. If you’re up for it, send us that photo you mentioned and we can help ID what you’re dealing with and recommend the right next step (or make this right for you)

Great product

I have been using this product for several years on a very resistant bull thistle that kept popping up all over my yard. It kills it dead in a few hours. I like that it is not poison and won't harm the environment or my kids or pets. It is super effective for spot treating only the weeds you want to...
