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.

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

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.

absolutely nothing was killed

its been a week after I have used your products, killed absolutely nothing. Followed instructions, and looks like I got more flowers instead of killing them.

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.

Dandelion Doom??? More like Dandelion Boom!!

I just subscribed to your lawn care program, and I was excited to try the Dandelion Doom that was sent to me.   So far, I have to say I am far from impressed with your product.   I followed the instructions for that spray, and I am not sure it killed even 1 dandelion in my yard.   I truly hope your ...

Thanks for sharing your experience with us! As listed in the FAQ section of our product page, Dandelion Doom can cause staining due to high iron content. Avoid using on sidewalks, concrete, or other hard surfaces. If you accidentally spill, immediately spray and dilute the area with water. For best results, apply on calm days to prevent overspray.

Clover laughs at this stuff. I did not find the product effective in getting rid of any weeds listed.

Did absolutely nothing

After reading reviews on here and Sunday support replies, I applied it as directed and it did nothing. I bought mine from Costco during an event. I was really hopeful but the weeds are still there and I applied directly to the weed leafs on a Sunny and warm day. I’m going to return the kit I purchas...

What does it kill??

So far, I've yet to find a weed that this will actually kill. I've used it in bright sunlight. I've given it time to let them die. I've used an ample application. But nothing is dying. Did I buy a worthless product?

Not for crabgrass

This product did absolutely nothing for our crabgrass problem. I was hoping to use all Sunday products since they seem to be safer, but I may have to resort to a different herbicide for the crabgrass

Thank you for sharing your experience! Dandelion Doom is an effective weed control option for broadleaf weeds, but it does not address grassy weeds like crabgrass. Crabgrass can be tricky, particularly because it's so biologically similar to turfgrass! Crabgrass germinates in the summer and thrives in even the toughest of conditions, so it's important to treat the issue as soon as you see it! Our non-selective herbicide, Weed Warrior, will be the most effective option when treating crabgrass and other similar growth. Just be careful when using it within your lawn, since it damages healthy grass as well if sprayed directly on it!

Not effective for me.

I applied on a sunny day and came back to the property a week later and no effect. Weeds that I treated still happily growing.

Waste of money

ALL of the dandelions I treated came back up within a few weeks. Every one. I spend a lot of money on this stuff. I recommend the Fiskars stand up weeder. WAY more effective and less expensive. If you have a big yard like we do, this stuff just won’t do it. If you have a small yard, and can reapply ...
