Ingredients

Chelated Iron (FeHEDTA) is the active ingredient. Iron occurs naturally in soil and your lawn already uses it. When sprayed directly on broadleaf weeds, they absorb the iron fast and it overwhelms them. Grass absorbs the iron slowly, so it tolerates the treatment. You may notice temporary darkening of your grass after application. That's just the iron doing its thing, and your lawn will bounce right back.

How to use

Apply when temperatures are between 50 and 85 degrees F and no rain is expected for at least 3 hours.

Pour one full bottle of Dandelion Doom into your reusable Sunday 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 leaves are entirely covered
Repeat treatment in 3 to 4 weeks for best results

FAQ

When should I use Dandelion Doom on my lawn?

Dandelion Doom Herbicide Concentrate works best from spring through fall when weeds are actively growing. Apply between 50 and 85 degrees F when no rain is expected for at least 3 hours.

Avoid mowing 1 to 2 days before and after treatment.

How long does it take for Dandelion Doom to work?

Dandelion Doom Herbicide Concentrate shows visible results within 1-2 days. Weeds darken and wilt as the iron formula takes effect.

For stubborn weeds, reapply every 3 to 4 weeks. Spray until leaves are entirely covered.

Why is my grass turning dark after applying Dandelion Doom?

Dandelion Doom Herbicide Concentrate can temporarily darken grass blades due to the iron formula. This is normal and your grass will recover.

Broadleaf weeds absorb iron faster than grass, which is how Dandelion Doom stays selective.

How do I apply the concentrate?

Dandelion Doom Herbicide Concentrate Refill requires the Sunday Herbicide Pouch and Sprayer in order to apply the product. The reusable pouch and sprayer are sold separately, or can be purchased as part of the Dandelion Doom Starter Pack

How is iron based weed control different from conventional weed killers?

Dandelion Doom uses iron chelate (FeHEDTA) instead of conventional ingredients like 2,4-D. Weeds absorb the iron quickly and it overwhelms them, while the grass remains unaffected.

No harsh chemicals. Also controls moss, algae, and lawn diseases like Dollar Spot.

What weeds does Dandelion Doom get rid of?

Dandelion Doom Herbicide Concentrate targets broadleaf weeds including dandelion, clover, thistle, chickweed, plantain, creeping charlie, and oxalis. Also controls moss, algae, and lichens.

It does not affect grasses or grass like weeds, or prevent new weeds from sprouting. Each 5 oz bottle treats up to 224 sq ft. The 2-pack covers 448 sq ft total.
