Helpful Tips from Lawn Advisors:

How does this lawn-safe weed killer work?

Grass and weeds absorb iron differently. Weeds quickly take in too much iron, which becomes toxic and kills them. Grass absorbs iron more slowly and can tolerate higher amounts. This difference allows us to target weeds while giving your lawn a healthy, deeper green color.

What's the difference between ready-to-use Dandelion Doom and the concentrate version?

This is a ready-to-use formula in convenient spray bottles - no mixing required. It's perfect for spot-treating individual weeds or small areas. The concentrate version is more economical for treating larger areas but requires mixing with water and using a sprayer system.

What weeds does Dandelion Doom control?

Dandelion Doom is effective on broadleaf weeds like black medic*, broadleaf plantain, bull thistle, Canada thistle*, common chickweed*, creeping buttercup, creeping charlie/ground ivy*, dandelion, dovefoot geranium*, English daisy*, false dandelion, healall*, moss, liverworts*, algae* and lichens*, narrow-leaved plantain*, oxalis, Persian Speedwell, prostrate knotweed*, shepherd’s-purse*, silverweed cinquefoil*, slender speedwell*, white clover, wild chamomile*.

It can also control or suppress diseases such as but not limited to*: Dollar Spot, Rust or Snow Mold.

*Not approved for this use in California. Please see California label for approved use.

Does Dandelion Doom stain?

Yes, it 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.

How to use Dandelion Doom with other Sunday products?

Ideally, apply weed control before seeding, fertilizing, or applying pest control. Allow to dry completely before applying other liquid products or watering your lawn. For best results with Sunday grass seed, wait one day after applying Dandelion Doom before seeding.

Killed my lawn

This killed about 5% of the weeds and killed 100% of the grass it was sprayed on. There's just big black spots on my lawn wherever I sprayed this. It looks like I torched my grass.

Worst product ever!

Purchase this for the first time (and last) to kill some dandelions coming in the yard. Sprayed and could tell zero affect after a day. Even more dandelions started coming in and I feel like it was a fertilizer more than a weed killer. Maybe I received a bad batch

Store Owner

Hi Zac, 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.

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.

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 ...

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.

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

Store Owner

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!
