Helpful Tips from Lawn Advisors:

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.

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

I used Dandelion Doom without success. I left a review and Sunday contacted me and worked though the issue with *and actual person*. They explained what may have happened and they sent me a different product to try after looking at pictures of the weeds in my lawn that I sent. Kudos for the advice a...

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!

Store Owner

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 ...
