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.

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 ...

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!

Didn’t work

Did the 2 rounds of this and neither worked to get rid of our weeds! We did it during dandelion season too!

Sunday

We're sorry to hear that your weed control results aren't as expected! Here are some Best Practices to follow for best results. 1.) Try to apply on a sunny day. While not mandatory, sunshine will improve the efficacy and speed of our herbicides. With sunshine unfiltered by clouds, our herbicides will work even better. A rainfall within 3 hours after application can make the herbicides ineffective. Optimal temperatures for application are between 50F to 85F. 2.) Apply when the weeds look healthy. When weeds are stressed or injured, weeds release hormones to recover. These hormones make herbicides less effective. Hormones are also released if weeds are mowed; we recommend not applying on the same day you mow. 3.) Apply the leaves liberally. Our herbicides just need to make contact with the leaves to work; trying to apply to the roots won't be effective. For best results, you want the leaves soaked, but not to the point where the herbicides is dripping off the leaves. 4.) Know the age of the weed. Older and established weeds will likely require more applications. For older weeds, we recommend doing multiple applications on the same day; just let the leaves dry out in-between applications.
