What makes Dandelion Doom Herbicide Concentrate Starter (2-pack) different

Visible results on broadleaf weeds in hours
Iron powered formula, no harsh chemicals
Comes with a battery-powered wand sprayer
Targets weeds without touching your grass
Also controls moss, algae, and dollar spot
Reusable pouch and sprayer for next time

Ingredients

Chelated Iron, FeHEDTA. A concentrated iron compound that broadleaf weeds absorb too quickly, causing them to dry out and brown. Grass absorbs it slowly and remains unaffected.

How to use

For best results, apply when temps are between 50 to 85 degrees F when no rain is expected for at least 3 hours.

Pour one full bottle of Dandelion Doom concentrate into the reusable 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 all the leaves are entirely covered.
Repeat treatment in 3 to 4 weeks, or as needed. Store your wand sprayer and pouch for future use.

FAQ

When is the best time to apply Dandelion Doom?

Dandelion Doom Herbicide Concentrate works best when temperatures are between 50 to 85 degrees F with no rain expected for 3 or more hours. Spray when weeds are actively growing for the strongest results.

Will Dandelion Doom hurt my grass?

Dandelion Doom Herbicide Concentrate targets broadleaf weeds, not grass. Grass absorbs iron slowly and uses it as a nutrient, so your lawn may actually look greener after application. Some temporary dark discoloration is normal.

What weeds does Dandelion Doom control?

Dandelion Doom Herbicide Concentrate controls broadleaf weeds including dandelions, clover, chickweed, creeping charlie, thistle, plantain, oxalis, and speedwell. It also controls moss, algae, lichens, and suppresses lawn diseases like dollar spot and rust.

How long does Dandelion Doom take to work?

Dandelion Doom Herbicide Concentrate shows visible results within hours of application. Fully drenched weeds will dry up within 24 hours depending on the size and maturity of the plant. Repeat treatment in 3 to 4 weeks if needed.

How does iron based weed control work on lawns?

Dandelion Doom Herbicide Concentrate uses iron (FeHEDTA) to overload broadleaf weeds. Weeds absorb the iron too quickly and it becomes toxic. Grass absorbs the iron slowly and tolerates higher amounts, so it stays healthy.

Can I use Dandelion Doom with other Sunday lawn products?

Yes! Dandelion Doom Herbicide Concentrate can be applied before or after lawn fertilizer. Let the weed control dry completely before applying other Sunday liquid products or watering your lawn. The longer it sits on the leaves, the more effective it is.

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

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.
