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*.

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.

Does not kill dandelions or creeping charlie

I had high hopes that this would work on dandelions and creeping charlie. It did not. Dandelions do wilt, but simply return. Creeping charlie was barely affected. Back to herbicides, unfortunately.

Wow… it killed them all!

This was my first time using dandelion doom. We are up in Bozeman MT with unpredictable weather right now but I made sure to choose the right day - sunny and warm with emerging, healthy dandelions (covering pretty much our entire lawn, they were out of control this year). So I took my time spraying ...

Not effective

We applied this product as instructed: it was the ideal temperature, on actively growing weeds, and applied as a spot treatment. I’d estimate it worked on less than half of the dandelions in our yard. After two emails with Sunday, their answer seems to be “apply it again. ” We used what was included...

Sprayer clogs

The product is a "4," but the sprayers are a "0. " I bought two sprayers at the end of last year to use this spring, but they clogged on the first use. I'm unsure what is getting stuck inside, but it is slimy and thick. I've tried shaking the concentrate to break up the gunk as best as possible. It ...

Did nothing for my weed covered lawn :(

Unfortunately, Dandelion Doom Weed Killer did nothing for my lawn. I drenched the leaves and spread heavily throughout but the lawn is still riddled with weeds! Some areas now have more weeds than before. I have also seeded twice after applying and I'm still under a bed of weeds.

Lacks killing power.

Dandelion Doom- Looks like it hurts the plants but doesn't kill them. I have made 2 batches of Dandelion Doom spray over the past 4 days, used it all. I still have dandelions, still in the same spots. Seems to hurt the plants the day of use and the next day but after 2 days they regain strength. I o...

Zombie plants

I can't believe all the 1 star reviews. Must be corporate Round-Up reps or something. The dandelions I've sprayed this on are dead as shit. They are all black and look like zombie plants next to the green grass.
