It can also control or suppress lawn diseases: dollar spot, rust and/or snow mold.

FAQ

How does 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.

How to use Dandelion Doom with other Sunday products?

You can apply weed killer, like Dandelion Doom, before or after lawn fertilizer. Allow weed control products to dry completely before applying any other Sunday liquid products or watering your lawn–the longer the plant absorbs the weed control, the more effective the application.

When will I see results?

Fully drenched weeds will dry up in as little as 20 minutes or up to 24 hours, depending on the size and maturity of the plant you are spraying.

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.

Sunday

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.

Not Impressed

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

Sunday

Hi Ted, 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.

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

Sunday

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 ...

I applied the this yesterday and woke up today to a completely dead lawn. It was heading in the right direction and now it’s a disaster. Is the dandelion spray supposed to kill all of your lawn???
