Your lawn deserves an iron-based weed killer

Dandelion Doom is a selective iron-based weed killer that targets dandelions, clover, chickweed, ground ivy, and moss without harming your grass. It handles visible weeds as a post-emergent spot treatment. One ingredient, no mixing, no harsh chemicals. Grab a bottle and get to work. For more weed coverage, try the Dandelion Doom Starter Pack.

What makes Dandelion Doom Ready-to-Use Weed Killer Spray different

Visible weed wilting starts within hours
Iron-based formula with no harsh chemicals
Ready to use with no mixing required
Works on all cool and warm season grasses
You can reseed just 1 day after applying

Ingredients

Chelated Iron (FeHEDTA) is absorbed rapidly, overloading broadleaf weeds causing them to dry out and die. Your grass absorbs the iron slowly, so it stays green and healthy.

How to use

Apply on a sunny day when temperatures are between 50 and 85 degrees F. Avoid spraying if rain is expected within 3 hours.

Shake the bottle well and adjust the nozzle to your desired spray pattern.
Spray directly onto weed leaves until they are fully covered.
Let the product dry completely before foot or pet traffic on the treated area.
Repeat in 3 to 4 weeks for stubborn or established weeds.

FAQ

When should I use Dandelion Doom?

Dandelion Doom works best when weeds are actively growing and temperatures are between 50 and 85 degrees F.

Apply on a sunny day with no rain in the forecast for at least 3 hours. Spring and fall are the prime windows for broadleaf weed control.

How long does Dandelion Doom take to work?

Dandelion Doom starts wilting some broadleaf weeds within hours of application.

Full results, including root kill, typically appear within 1 to 2 weeks. Established weeds may need a second application 3 to 4 weeks later.

Will Dandelion Doom kill my grass?

Dandelion Doom is a selective weed killer, meaning it targets broadleaf weeds while leaving your grass unharmed.

It works on all cool and warm season grass types when used as directed. Grass absorbs iron more slowly than weeds, so your lawn stays green while weeds dry out.

Does Dandelion Doom stain concrete or sidewalks?

Dandelion Doom contains iron, which can stain hard surfaces like concrete, pavers, and sidewalks.

Avoid spraying on or near hard surfaces. If you accidentally spill, immediately dilute the area with water to reduce staining.

What weeds does Dandelion Doom kill?

Dandelion Doom controls broadleaf weeds including dandelions, clover, chickweed, creeping charlie, thistle, plantain, oxalis, knotweed, speedwell, and more.

It also controls moss, algae, and lichens, and suppresses lawn diseases like Dollar Spot, Rust, and Snow Mold.

What is the difference between the ready-to-use spray and the concentrate?

Dandelion Doom Ready-to-Use comes in pre-mixed spray bottles, ideal for spot treating individual weeds. No mixing, no assembly, just squeeze the trigger sprayer for fast weed control.

The concentrate covers more area and has an easier application style for larger lawns, but requires mixing with water and the Sunday Herbicide Pouch and Sprayer system to apply.

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...

No Success

I used this product as the instructions stated but received negative results. It was 0% effective on my yard, so I’m very hesitant to try it again. I was hoping for success, but it looks like I’ll have to switch to another weed control product.

Them weeds be dead

Not sure why these other people are saying it didn’t work. It killed almost all of my weeds. Did use a lot more product than expected but it killed the weeds without harming the grass.

No Dead Weeds in Our Florida Lawn

This weed killer came with our lawn plan. I applied as directed, and not one weed was killed in our Florida lawn. About a month later, I bought an Ortho product, and that did the trick. Dandelion Doom is worthless.

Waste of Money

Should have listened to the other negative reviews before buying. Followed directions, applied in sunny/dry conditions, and even applied to a variety of different weeds. It's been two days, and every single weed is still alive and well.

Great Product

I used this product approximately 24hrs ago on my lawn on both clover and some broad leaf weeds and I can see it working already. The weeds have already browned and are shriveling while the grass has remained healthy. I used this product with some level of skepticism after reading the other reviews ...

Sunday Customer Service is Great

I used Dandelion Doom without success. I left a review and Sunday contacted me and worked though the issue with *and actual person*. They explained what may have happened and they sent me a different product to try after looking at pictures of the weeds in my lawn that I sent. Kudos for the advice a...

Doesn’t kill Zoysia

Really happy to have finally found a product I can spray on my Zoysia lawn that doesn’t kill it! So nice to not have to get on my hands and knees anymore to pull the weeds from my lawn. So happy to have finally found this product! You guys rock!
